Abstract

The invention discloses a generation method of a label-based JSP (java server pages) form read-only page code. A JSP form page generally comprises a group or a plurality of groups of input fields; and when a modification status is added, the form elements are generally displayed in a programmable status. But in browsing status, the form elements are designed to be in a read-only status, and page resources can be shared. By the page design process, although a page code can be shared, a display effect is not good. Conventionally, the read-only status is displayed as a text according to a printing format, instead of an input control format. By a user-defined label technology, the invention provides a page code generation method, so that in the read-only status, through automatically controlling the input fields by a switch, the form page has a final display effect on a page that the programmable status is displayed as a control, and the read-only status is displayed as the text. By the generation method, perceptibility of the page is increased, and data which are required to be displayed on the form page are expressed more clearly.

Description

A kind of read-only page code of Jsp list generation method based on label

Technical field

The present invention relates to areas of information technology, particularly the realization of the read-only state code generation of JSP label.

Background technology

The forms pages generation technique is the common technique in the Web application and development.The code of forms pages generally meets the html standard.Comprise one group or the input domain of organizing, when increasing the modification state, but Form Element is shown generically editing mode more.And when browse state, general designing form element is a read states, and page resource can be shared.The processing of this Pages Design, although can share same page code, display effect is not good.Convention, a read states generally can directly be shown as text according to print format, rather than adopt the input control pattern.The present invention is by the customized label technology, a kind of page code generation method is provided, so that in forms pages below a read states, by the final display effect of the automatic control inputs of switch territory on the page: but editing mode is shown as control, a read states is shown as text.By the method, can improve the perceptibility of the page, express more clearly the data that forms pages need to show.

Summary of the invention

The invention discloses a kind of read-only page code of Jsp list generation method based on label, realize same forms pages resource by the mode that defines the label read only attribute, below read-only and editor's two states, generate different html scripts.Simultaneously, aspect status attribute, provide control levels and list rank two kinds of control modes.

For achieving the above object, the invention provides the self-defined controls tab of a cover.The label that comprises Windows form controls commonly used is such as single-line text boxes, multiline text frame, drop-down frame, radio box, the check box of selecting.

The attribute of label is designed with Provider attribute and Status attribute.The Provider attribute is used for the binding relationship of description value; Status as abstract factory final represent pattern, by this Status switch attribute, select different code generators to make up the html script that label finally represents.Read-only like this and editor's two states page can use same page resource, but is presented as distinct page effect.

The attribute of label also comprises the attribute commonly used of general Form Element type, to support corresponding Form Element function.

The present invention also provides the Form form tags.Form tags provides Provider and Status attribute.The show state of the whole list of Status property control, subordinate's form controls label can be inherited this attribute, when the Form label is provided with the Status attribute, all controls of whole list will be preferentially according to the state control display of Form label.

The present invention also provides the method for input thresholding binding.The Provider attribute is used for arranging the bound object of respectively inputting thresholding in the list.Empty object is that initialization list, value object are editor's list.The binding of value is transmitted by the jstl expression formula.Object type is Map＜String, String 〉, key and Form Element are of the same name, and value is the value of Form Element.

The present invention also provides the dictionary table caching function.But during the binding of element value, the input input frame is directly finished the assignment of object by the key/value of Map.The assignment of select is carried out the name conversion of key by provider.The buffer memory of dictionary data is dynamically finished.Buffer structure is designed to ConcurrentHashMap＜name, Map＜String, String〉〉.

Can be found out by such scheme, the read-only page code of control Jsp list attribute that arranges by tag attributes among the present invention generates, and realizes same forms pages resource, below read-only and editor's two states, generates different html scripts.Accelerate inquiry and the binding of page data by the mode of dictionary buffer memory.

Description of drawings

In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art.

Figure is system architecture schematic diagram in the embodiment of the invention.

Embodiment

For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further illustrated below in conjunction with the drawings and specific embodiments.

Embodiment one, referring to figure.

The invention provides a kind of read-only page code of Jsp list generation method based on label, realize same forms pages resource by the mode that defines the label read only attribute, below read-only and editor's two states, generate different html scripts.Its development and implementation process is as follows:

1) in the web project, adds tag library jar bag.

2) create the jsp page, in the page, import tld.

3) at the jsp page, add the form label, status attribute and provider attribute are set, the provider attribute imports Map＜String into, String 〉.

4) in the form label, add controls tab, the status attribute is set.When having specified status such as form, the status attribute that control arranges is invalid.

5) start web server, browse the status page, view result.

6) switch form label status attribute, again browse the status page, view result.

Can be found out by such scheme, pass through the customized label technology among the present invention, a kind of page code generation method is provided, so that in forms pages below a read states, by the final display effect of the automatic control inputs of switch territory on the page: but editing mode is shown as control, a read states is shown as text.By the method, improved the perceptibility of the page, express more clearly the data that forms pages need to show.

Claims

1. the read-only page code of Jsp list generation method based on label, it is characterized in that: designed one group of controls tab that comprises the Status attribute, the label that comprises Windows form controls commonly used is such as single-line text boxes, multiline text frame, drop-down frame, radio box, the check box etc. of selecting; Also comprise simultaneously the containers labels such as Grid, Window; Label comprises particular community: Status, and as the switch of the final display effect of abstract factory, when the status attribute was edit, label was shown as control; When if the status attribute is read, label only is shown as text message, and design and browsing pages can use same rower label code like this.

2. the read-only page code of Jsp list generation method based on label, it is characterized in that: designed one group of form tags that comprises the Status attribute, it is characterized in that: form tags also comprises the Status attribute, as the overall situation setting of whole label; When list is provided with the Status attribute, each the input domain label in the list can both be inherited this attribute so.
