Introduction to the second Internet: scriptcript extraordinary understanding, at least, its web development javascript web development appear competent enough to return to the contents of the PAGE of callbehind updates, so there is certainty DEV threshold increases when the Ajax-based mechanism to stop when DEV , under the original method based on postbehind time, asp.net source code from the backend logic (Model), aspxPAGE (View), aspx.cs (Controller) MVC framework consisting of failure in fact, when callbehind return data, either in the client end web development web development using javascript to return the content to appear updated analysis, or server-side configuration is necessary ... in the body: 1, difficult background
Currently, more and more people start trying to stop non-Based Ajax refresh WebDEV, however,. Net environments, the actual use of Ajax is not easy as unusual, mainly estimated by the following part of the reason is due to:
• Since the Ajax web development javascript-based nature of web development, making the need for javascript DEV Zhe development Feibixunchang understanding of network development network, at least, the javascript development web development network appear on the callbehind competent enough to return to the contents of the PAGE updates, so the DEV's determine the degree of increase in the threshold there is
* Ajax-based mechanism to stop the DEV when when under the original method based on postbehind when, / 'target =' _blank 'class =' infotextkey '> asp. Net from the back-end logic (Model), aspxPAGE (View), aspx.cs ( Controller) MVC framework consisting of failure in fact, when callbehind return data, either in the client-side javascript web development web development by parsing the content returned by an update, or server-side structure is necessary to better compete in the complete source code for static pages, and then directly from the web development javascript web development constructed to a good set of static pages PAGE object, it is clear that as a result, there should be a function of the easiest callbehind, should a lot of source code, and is relatively random contest source code, even in the difficult coming asp.net2.0 still not been effectively resolved
2 The purpose of this
This paper aims to fully conducive to the existing asp.net ajax own characteristics and features, made for a stop under the asp.net ajax the webDEV the MVC-based solutions to the following main objectives:
· Asp.Net Ajax environment for a clear MVC architecture
Reduced everyone too much javascript coding web development web development to reduce dependence on the threshold of English
• Flexible support of the daily DEV ajax mode method
3, difficulty planning
How to appear above the main purpose?
1) To xmlhttprequest for a better package, so call the method is more simple;
2) Try to update the data in the server side to stop the construction, but also to avoid the hand each time to return data structure, therefore, to expect did not score the full application of UserControl, the UserControl as the "View", corresponding to the document as by the ascx.cs " Controller ", consisting of MVC is also a contest as a clear;
4, difficult to solve
Based on the above ideas, a person to the group following a class library to simplify the process:
Source Code Analysis:
1) First in the client side, AjaxHelper.js encapsulates the xmlhttprequest, and will be available to help a
Sequence into the form param1 = v1 ¶ m2 = v2 & ... form for the post of parameters;
Update r (ajaxTemplate, output, params, onComplete) parameters for the call once callbehind
ajaxTemplate (required): Specifies the path UserControl run demand function
output (optional): Fill the prescribed label to return the data reference or IDvalue
params (optional): form param1 = v1 ¶ m2 = v2 & ... the post parameters
onComplete (optional): returns the data can be used to stop the special treatment of the callback parameter, the parameter formatting function (str), str for the returned data
SerializeForm (form) parameters for the sequence of
form: no result is specified reference or IDvalue
2) In the server side, Ajax.aspx documentation package for the specified by the client ajaxTemplate UserControl call, the rest of the specific logic function in a particular UserControl and ascx.cs appeared in;
3) as a callbehind specific run, the English we simply PAGE reference AjaxHelper.js, and in the specified location through the web development web development javascript: Update r (ajaxTemplate, output, params, onComplete) to stop calling, if the demand Stop a form submission, you can call the javascript web development web development: SerializeForm (form) sequence of the form and pass params, of course, did not score manually constructed params, and returns the data specified by set output or through the practical application of the PAGE onComplete custom processing.
4) The full use of UserControl, means that the results did not make full use of existing side asp.net controls and data binding mechanisms, as a matter of fact, has largely simplified the return data structure, in ascx.cs, after Request.Form [ParamName] visit to the client side will be able to pass the params, then visit the logic source code for the source data.
