我刚刚转移到了不显眼的阿贾克斯附带MVC-3，但在突破一个点。 这里是我的链接

i have just shifted to unobtrusive ajax that ships with mvc-3 but it is breaking at one point. Here is my link

<%:Ajax.ActionLink("Edit", "Home", "Edit", new{id = Model.SomeID}, new AjaxOptions{OnSuccess = "DoSomething"})%>

这是将要叫上我的成功js函数

this is my js function that will be called on success

<script type="text/javascript">
function DoSomething(data)
{
    var clickedLinkID = this.id; // this line breaks it used to work with microsoft ajax
    //rest of code goes here
}
</script>

我发现这篇文章中，伊姆兰介绍了如何解决这个问题。但它涉及到添加一行jquery.unobtrusive-ajax.js。它有什么副作用？我应该会改变jQuery的文件吗？如果没有我怎样才能被点击，如果不改变jquery.unobtrusive-ajax.js文件的链接的ID

i found this article in which imran describes how to solve the problem. but it involves adding one line to jquery.unobtrusive-ajax.js. Does it have any side effects? should i be changing jquery files? if not how can i get id of the link that was clicked without changing jquery.unobtrusive-ajax.js file

推荐答案

下面是编辑MS不显眼的AJAX包括新缩小的版本的完整副本。它包含的范围内（源元素缺失）加固定的另一个重要修正，由此所记录的取消类应用时，提交的项目已被拒绝（应该prevent验证，但没有）。

Here is a complete copy of edited MS unobtrusive AJAX including a newly minified version. It contains the context (source element missing) fix plus another important fix whereby the documented "cancel" class was not honoured when applied to submit items (should prevent validation but doesn't).

我失望的是，这些关键的正常行为的修复还没有在这么长的时间（特别是由于只有三种简单的编辑）纠正。即使是最新的2013年9月发布的AJAX工具包的依然采用了现在传统的SYS微软的AJAX库，而在世界其他地区已经迁移到jQuery用户界面。也许这都将使用Visual Studio的RTM澄清2013具体的MVC 5？

I am disappointed that these critical normal behavioural fixes have not been corrected in such a long time (especially since there are just three simple edits). Even the latest September 2013 release of the AJAX toolkit is still using the now legacy "Sys" Microsoft AJAX Library whilst the rest of the world already migrated to jQuery UI. Maybe this will all be clarified with the RTM of Visual Studio 2013 specifically MVC 5?
