Abstract
The invention discloses an input method based on XMLHttpRequest. The input method based on the XMLHttpRequest comprises the steps that an input command is generated by an input method module; an XMLHttpRequest module detects the input command, carries out protocol conversion and generates a URL request; and a browser module detects the URL request and executes the input command corresponding to the URL request. The input method and device based on the XMLHttpRequest disclosed by the invention are characterized in that the command in the input method is converted into the URL request by the XMLHttpRequest module through a certain protocol, and internal communications with a browser can be implemented; and corresponding treatments are executed inside the browser according to the different commands, so that interactions between an input method UI and the browser are realized. In this way, difficulty in transplantation and re-development can be reduced greatly.

Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of input method based on XMLHttpRequest, and with reference to Fig. 1, the described input method based on XMLHttpRequest comprises the following steps:
Step S10, input method module generate input order.
Further, with reference to Fig. 2, described input method module generates the concrete steps of input order and includes:
Step S11, obtain current focus positional information.
Step S12, generate the input order corresponding with the button being positioned at described position.
Further, with reference to Fig. 3, the concrete steps of the input order that described generation is corresponding with the button being positioned at described position include:
Step S14, judging the type of button, described push-button type includes character input button, function button and logical buttons, and described character input button includes letter input key and numeric input keys, and described function button includes back deleting button and removing button；Described logical buttons includes capital and small letter switching key, language switching key, symbol/letter switching key and multiselect character display button.
If the described button of step S15 is character input button, then obtain the character of correspondence, by character assignment in corresponding global variable, and generate character input order.
If the described button of step S16 is function button, then obtain the key assignments of correspondence systematic function input order.
If the described button of step S17 is logical buttons, then calls the power function of correspondence, and generate logic input order.
Specifically, user is by by directionkeys moving focal point, acquiring unit in input method module obtains the positional information of current focus, simultaneously, logic judgment unit in input method module judges the push-button type being positioned on this position, described push-button type includes character input button, function button and logical buttons, and described character input button includes letter input key and numeric input keys, and described function button includes back deleting button and removing button；Described logical buttons includes capital and small letter switching key, language switching key, symbol/letter switching key and multiselect character display button.If belonging to special function keys, then special function keys list is gone to obtain corresponding key value structure；If belonging to general character input key, the coordinate position that current language is corresponding is then gone to obtain corresponding character, and the key assignments now obtained is assigned to a certain global variable keyval, when user presses acknowledgement key (OK key), logic judgment unit does corresponding operation according to current key assignments, if input method module internal logic button then calls corresponding power function and changes the display of the page, such as switch current language, switching capitalization is little, switching symbol/letter, language is configured and multiselect character shows, here multiselect character refers to the different display modes of same letter, such as French, character ' c' has four kinds of display modes, be respectively ' c', ''、''、''；If the function buttons such as submission or character display button are then processed by corresponding power function.
Step S20, XMLHttpRequest module detect input order, and carry out protocol conversion, generate URL request.
Specifically, XMLHttpRequest module is mainly the logic requests of input method module according to a certain agreement, it is organized as specific HTTP request by certain mode, form is as follows, protocol therein (agreement) can be any custom protocol word string, such as, webime: // etc..Cmd_name and arg is incoming order and parameter.
Such as can pass through such as the transmission input command information that gives an order:
Above-mentioned code represents and sends input command information by the OPEN function of XMLHttpRequest object, Send function, after browser module receives the request of this agreement, and resolve command and parameter, do corresponding action.XMLHttpRequest is to liking the page creation in input method module, and browser module itself is a container, it is possible to open the different pages.
Step S30, browser module detect described URL request, and perform the input order of corresponding described URL request.
Further, with reference to Fig. 4, described browser module detects described URL request, and the concrete steps performing the order of corresponding described URL request include:
Step S31, described URL request is carried out protocol filtering and command analysis.
The order that step S32, basis parse performs corresponding order with parameter, and described order is by browser inter-process the input frame being output as Web page.
Specifically, Browser processes custom protocol request according to event message type, and obtain request data, described data comprise URL information, described URL information is filtered processing by browser, if the protocol header of request comprises the custom protocol webime of input method: //, then forward corresponding flow processing to, parse order and parameter, and carry out corresponding action.Such as show/hide input method, input validation, return functions such as deleting.
Embodiments of the invention by XMLHttpRequest module by the order in input method through certain protocol conversion be URL request and browser intercommunication, different orders is done corresponding process by browser internal needle, reach the purpose that input method UI interface is mutual with browser, thus the difficulty reducing transplanting to a great extent, developing once again.
