ASP.NET MVC 3和jquery.unobtrusive，ajax.min.js [英] ASP.NET MVC 3 and jquery.unobtrusive-ajax.min.js

问题描述

我想使用的Ajax.ActionLink HTML辅助，因此我需要jquery.unobtrusive-ajax.min.js库，但IE浏览器总是显示此错误：

  

微软JScript运行时错误：无法设置属性不显眼的值：对象为null或undefined

我读过的解决方案是jquery.validate.min.js和jquery.validate.unobtrusive.min.js的用法但我不能识别服务器端的Ajax调用。

解决方案

  

我读过的解决方案是jquery.validate.min.js的使用和
  jquery.validate.unobtrusive.min.js

没有，那些2脚本都无关 jquery.unobtrusive-ajax.min.js 。它们被用于不显眼验证。对于Ajax。*帮手你需要的是的jQuery 和 jquery.unobtrusive-ajax.min.js （包含在< STRONG>该顺序）。

因此​​，对于不显眼的AJAX你需要：

 ＆LT;脚本的src =@ Url.Content（〜/脚本/ jQuery的-1.5.1.min.js）TYPE =文/ JavaScript的＆GT;＆LT ; / SCRIPT＆GT;
＆LT;脚本的src =@ Url.Content（〜/脚本/ jquery.unobtrusive-ajax.min.js）TYPE =文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
 

如果你想使用不引人注目的验证你也可以包括2个脚本之后（在该顺序排列）：

 ＆LT;脚本的src =@ Url.Content（〜/脚本/ jquery.validate.min.js）TYPE =文/ JavaScript的＆GT;＆LT; /脚本＆GT;
＆LT;脚本的src =@ Url.Content（〜/脚本/ jquery.validate.unobtrusive.min.js）TYPE =文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
 

这是你应该确保另一个非常重要的事情是，你已删除微软的* .js 从项目脚本绝对任何痕迹。这些脚本已过时，从ASP.NET MVC 3开始不再默认使用。此外，确保启用挥霍在你的web.config不显眼的AJAX，否则系统会退回到传统的Microsoft AJAX脚本：

 ＆LT;＆的appSettings GT;
    ＆LT;添加键=网页：版本值=1.0.0.0/＆GT;
    ＆LT;添加键=ClientValidationEnabledVALUE =真/＆GT;
    ＆LT;添加键=UnobtrusiveJavaScriptEnabledVALUE =真/＆GT;
＆LT; /的appSettings＆GT;
 

I want to use the Ajax.ActionLink Html helper therefore I need the jquery.unobtrusive-ajax.min.js library but IE is always showing this error:

Microsoft JScript runtime error: Unable to set value of the property 'unobtrusive': object is null or undefined

I've read that the solution is usage of jquery.validate.min.js and jquery.validate.unobtrusive.min.js but then I can't recognise the ajax call on server side.

No, those 2 script have nothing to do with jquery.unobtrusive-ajax.min.js. They are used for unobtrusive validation. For Ajax.* helpers all you need is jQuery and jquery.unobtrusive-ajax.min.js (included in THAT order).

So for unobtrusive AJAX you need:

<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>

If you want to use unobtrusive validation you could also include the 2 scripts afterwards (in THAT order):

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

Another very important thing that you should make sure is that you have removed absolutely any traces of Microsoft*.js scripts from your project. Those scripts are obsolete and starting from ASP.NET MVC 3 are no longer used by default. Also make sure that youhave enabled unobtrusive AJAX in your web.config, otherwise the system will fallback to the legacy Microsoft ajax scripts:

<appSettings>
    <add key="webpages:Version" value="1.0.0.0"/>
    <add key="ClientValidationEnabled" value="true"/>
    <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
</appSettings>
