It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
One embodiment of the invention discloses a kind of map label method, as shown in Figure 1, method includes the following steps:
Step 101: when receiving the drag operation for the target mark object on map, forbidding itself of the map
Drag function；
In the present invention, drag function can be added for the element on map in advance, so that in triggering for map
It, can be by the way that irremovable element, these elements can be referred to as to mark originally on drag operation moving map when mark behavior
Infuse object.That is, mark object is the element for being attached with drag function on map.Optionally, it is receiving for the target on map
Before the drag operation for marking object, further includes: utilize DOM (Document Object Model, DOM Document Object Model) operation side
Method is that the element on map adds drag function, and it is mark object that determining, which has the element of the drag function,.The DOM operating method
Operating method including Jquery UI operating method or javascript DOM.
The drag operation can operate to touch drag operation or mouse drag.
When determining that the mark behavior for map starts, determine that the dragging object of drag operation is target mark object, and
Forbid itself drag function of map.Wherein, it triggers there are many modes for the mark behavior of map, for example, can pass through
Click map on a certain specific keys mode trigger or to map on a certain element carry out predetermined operation when triggering,
The time for such as clicking a certain element reaches preset time, determines that triggering is directed to the mark behavior of map, and determines that the element is mesh
Mark mark object.
It should be noted that the current display area that itself drag function of map is map can be based on drag operation
The function of change, and itself drag function of map can not change the geographical position coordinates of the element on map.
Step 102: at the end of the drag operation, determining the target mark of the target mark object on the map
Position；
Wherein, when drag operation of the release for target mark object, determine that drag operation terminates, at the end of drag operation
Target mark object position is target labeling position of the target mark object on map.For example, user marks object to target
Drag operation is carried out, discharges, determines after target mark object is dragged to the second position on map by the first position on map
Drag operation terminates, which is that target marks target labeling position of the object on map.
Optionally, target labeling position can be manually entered by user；Certainly, in the present invention, system can also be counted automatically
Target labeling position is calculated, can be specifically discussed in detail later.
Step 103: saving the corresponding relationship of target the mark object and the target labeling position.
The corresponding relationship that object and target labeling position are marked by saving target is realized for the map after mark more
Newly.
In an alternative embodiment of the invention, this method further include: by target mark object pass corresponding with target labeling position
System is sent in server；And/or the corresponding relationship of target mark object and the target labeling position is updated to and institute
In the data for stating the outer elements correlation of map.
Wherein, server is sent to which realization is directed to by the corresponding relationship that target is marked object and target labeling position
The long-range update of map after mark.
With the data of element outside map can for the associated object of map, be managed collectively and tieed up for map
Shield.
It can be seen that in the present embodiment, when receiving the drag operation for the target mark object on map, forbidding
Itself drag function of the map determines target mark object on the map at the end of the drag operation
Target labeling position saves the corresponding relationship of target the mark object and the target labeling position.I.e. the present invention can pass through
Drag operation realizes the dragging to target mark object, so that it is determined that the target labeling position of the target mark object after pulling, is realized
The dynamic label placement of to map, improves the convenience of mark.
Another embodiment of the present invention discloses a kind of map label method, as shown in Fig. 2, method includes the following steps:
Step 201: when receiving the drag operation for the target mark object on map, forbidding itself of the map
Drag function；
Step 202: at the end of the drag operation, obtaining outside the target mark object and the predetermined map
Base position between the first offset；
Base position is used to calculate the offset between the first position on target mark object and map, which is
A position outside map, can be preset, or specified by user by system.
It optionally, can be using the upper right Angle Position of the Webpage where map as base position, alternatively, can be by ground
The upper left position of Webpage where scheming is as a reference value, and the present invention is not limited thereto certainly；For example, if current aobvious
Show interface while showing map and another display object, it is possible to using a certain position of another display object as base
Level is set.
Step 203: obtaining the second offset between the first position and the base position on the predetermined map
Amount；
First position on the map can also be set based on actual conditions, for example, can be by the upper left on map
Angle Position is perhaps made using the lower right position on map as first position or by map center location as first position
For first position.
Step 204: the target mark object and described the are calculated based on first offset and second offset
Third offset between one position；
First offset and the second offset are made into difference and obtain the third offset between target mark object and first position.
Step 205: determining that the target of the target mark object on the map marks position using the third offset
It sets.
It should be noted that it is exactly picture of the target mark object on map that target, which marks target labeling position of the object on map,
Plain coordinate.And pixel coordinate of the target mark object on map is determined based on the base coordinate on map, i.e., target marks object
Offset with base coordinate position is pixel coordinate of the target mark object on map.Under normal circumstances, the base coordinate
Position be map on upper left position.It is preferred, therefore, that can be using the upper left position on map as the first of map
Position.
Therefore, determine that the target of the target mark object on the map marks position using the third offset
It sets, may include:
When determining the first position is the base coordinate position of map, directly using the third offset as described in
Target marks the target labeling position of object on the map；
When determining the first position not is the base coordinate position of map, the third offset is converted to described
Target marks the offset of object and the base coordinate position, then exists the offset after conversion as target mark object
Target labeling position on the map.
It certainly, in the present invention, can also be using the upper right Angle Position on map as the position of basic coordinate.
In order to make it easy to understand, being illustrated with a simple examples, as shown in Figure 3a, it is assumed that base position is net where map
The upper left position A of page S1, first position are the upper left position B on map S2, and target marks level in the position on map S2
Set C.
So, the first offset between target mark object position C and base position A is (a1, b1), first position B
The second offset between the A of base position is (a2, b2), to mark object position C and the by calculating target as difference
Third offset between one position B is ((a1-a2), (b1-b2)).In this example, based on the upper left position B on map
Coordinate position, therefore, third offset are ((a1-a2), (b1-b2)), and the pixel coordinate on map of object is marked for target,
As target labeling position of the target mark object on map.
As shown in Figure 3b, as the center D on the map that first position is map S2, then, target marks where object
The first offset between position C and base position A is (a1, b1), and the second offset between first position D and base position A is
(a3, b3), thus by making difference to calculate target to mark the third offset between object position C and first position D to be ((a3-
A1), (b3-b1)).
In this example, the upper left position B on map is basic coordinate position, then, need by third offset into
Row conversion, is converted into the offset of target mark object position C and the upper left position B on map.Specifically, determining
The offset between upper left position B on center D and map, the present embodiment are referred to as the 5th offset, the 5th offset
Amount is (a4, b4), then obtaining the offset for the upper left position B that target marks on object position C and map by making difference
For ((a4- (a3-a1)), (b4- (b3-b1))), the offset after converting marks pixel coordinate of the object on map into target, i.e.,
Target labeling position of the object on map is marked for target.
It should be noted that the offset between two positions include two positions offset in the horizontal direction and
Offset on vertical direction.
It can be seen that the present embodiment can realize the dragging for marking object to target by drag operation, so that it is determined that pulling
The target labeling position of target mark object afterwards, realizes the dynamic label placement of to map, improves the convenience of mark.
In the present invention, the operation such as amplify, reduce, moving for the ease of user's to map, when dragging for map
After dragging operation, it can be again started up itself drag function of map, and after starting itself drag function of map, map
State can cause to change by the operation such as pulling, zooming in or out.When the state of map changes, target will lead to
Pixel coordinate of the object on map is marked to change, therefore, it is necessary to redefine the target labeling position of target mark object, this
It invents another embodiment and discloses a kind of map label method, to realize the target labeling position after map state changes
Redefine.
As shown in figure 4, method includes the following steps:
Step 401: when receiving the drag operation for the target mark object on map, forbidding itself of the map
Drag function；
Step 402: at the end of the drag operation, starting itself drag function of the map；
In order to not influence the dragging behavior for being directed to map itself, in the present invention, when for the dragging behaviour of target mark object
At the end of work, start itself drag function of map, it is possible to the dragging for map itself be realized, for the sheet of map
The drag operation of body includes at least amplifying operation, reduction operation, moving operation.
Step 403: obtain between the base position outside target mark object and the predetermined map first partially
Shifting amount；
Step 404: obtaining the second offset between the first position and the base position on the predetermined map
Amount；
First position on the map can also be set based on actual conditions, for example, can be by the upper left on map
Angle Position is perhaps made using the lower right position on map as first position or by map center location as first position
For first position.
Step 405: the target mark object and described the are calculated based on first offset and second offset
Third offset between one position；
First offset and the second offset are made into difference and obtain the third offset between target mark object and first position.
Step 406: after starting itself drag function of the map, when the state for determining the map changes
When, the third offset is converted to the geographical position coordinates of the target mark object；
The geographical position coordinates are the practical latitude and longitude coordinates that target marks object.The practical longitude and latitude of element on map is sat
Mark is to be calculated based on the preset base coordinate on map, and under normal circumstances, the position of the base coordinate is ground
Upper left position on figure.It is preferred, therefore, that can be using the upper left position on map as the first position of map.
Correspondingly, the third offset to be converted to the geographical position coordinates of the target mark object, comprising:
When determining the first position is the base coordinate position of map, the third offset is directly converted into institute
State the geographical position coordinates of target mark object；
When determining the first position not is the base coordinate position of map, the third offset is converted to described
Target marks the offset of object and the base coordinate position, then the offset is converted to the ground of the target mark object
Manage position coordinates.
The conversion regime can be calculated based on coordinates transformation method, and which is existing calculation, the present invention
Excessive explanation is not done.It should be noted that needing to calculate the geographical position of target mark object when the state of first time map changes
Set coordinate, and when the state of map later changes again, then be used directly the geographical position coordinates, without each
All recalculate.
In the present embodiment, after starting itself drag function of the map, first determine that the state of the map changes
Become, then the third offset is converted to the geographical position coordinates of the target mark object.And in another embodiment of the present invention
In, the third offset first can be converted to the geographical position coordinates of the target mark object, and stored, work as determination
When the state of the map changes, the geographical position coordinates are directly utilized.
Step 406: the geographical position coordinates being inverted to coordinate system locating for the map, obtain the target mark
Coordinate position of the object on the map after state changes, using the coordinate position as target mark object in institute
State the target labeling position on map；
After starting itself drag function of map, the current state of map may change, when the current shape of map
When state changes, it will lead to pixel coordinate of the identified target mark object on map and change, it is therefore desirable to again
Determine coordinate position of the target mark object on the map after state changes.Due to the geographical position coordinates of target mark object
It is the accurate location of target mark object, therefore coordinate system locating for map can be inverted to based on geographical position coordinates, obtains mesh
Mark coordinate position of the labeling position on the map after state changes.
In the present embodiment, the coordinate position obtained after reversion is target mark position of the target mark object on map
It sets, if determining the target labeling position of the target mark object on the map using third offset before, that
, the replacement of the two need to be only carried out, that is, the coordinate position redefined is utilized to replace predetermined target labeling position.
It should be noted that the third offset for target to be marked object and first position is converted to geographical position coordinates
Coordinates transformation method and the coordinate for the 4th offset that geographical position coordinates are reversed to target mark object and first position are converted
Algorithm is just opposite algorithm.
Based on example above, as shown in fig. 5, it is assumed that target labeling position becomes from C1 point after the state of map changes
For C2 point, then, it is that target marks object and exists by the 4th offset (a5, b5) after the geographical position coordinates conversion of target mark object
Pixel coordinate on map S2, as target labeling position.
Step 407: saving the corresponding relationship of target the mark object and the target labeling position.
It can be seen that the present embodiment can realize the dragging for marking object to target by drag operation, so that it is determined that pulling
The target labeling position of target mark object afterwards, realizes the dynamic label placement of to map, improves the convenience of mark.

Coordinate position of the target mark object on the map after state changes is stated, using the coordinate position as the target
Mark the target labeling position of object on the map.
After starting itself drag function of map, the current state of map may change, when the current shape of map
When state changes, it will lead to pixel coordinate of the identified target mark object on map and change, it is therefore desirable to again
Determine coordinate position of the target mark object on the map after state changes.Due to the geographical position coordinates of target mark object
It is the accurate location of target mark object, therefore coordinate system locating for map can be inverted to based on geographical position coordinates, obtains mesh
Mark coordinate position of the labeling position on the map after state changes.
In the present embodiment, the coordinate position obtained after reversion is target mark position of the target mark object on map
It sets, if determining the target labeling position of the target mark object on the map using third offset before, that
, the replacement of the two need to be only carried out, that is, the coordinate position redefined is utilized to replace predetermined target labeling position.
It should be understood that the third offset for target to be marked object and first position is converted to geographical position coordinates
The coordinate of coordinates transformation method and the 4th pixel coordinate that geographical position coordinates are reversed to target mark object and first position turns
Scaling method is just opposite algorithm.
