如何使用 Ajax.BeginForm 更新 div 并执行 javascript 函数?

我正在使用这样的方法更新带有部分视图的 div:

<% using (Ajax.BeginForm("Action", "Controller",
               new { id=Model.id },
               new AjaxOptions
               {
                   UpdateTargetId = "divId",
                   InsertionMode = InsertionMode.InsertAfter,
               }))
   {  %>

它工作正常,返回的视图被附加到 div,但是我现在需要在发布成功时执行 JavaScript,所以我想:“简单,只需将 OnSuccess = "MyJsFunc()" " 添加到 AjaxOptions 即可,但这样做后,它停止工作了!现在页面已刷新,并且仅呈现返回的部分视图:(,我什至尝试使用简单的 Alert("Hi") 并且它不起作用。我怎样才能让它工作?

(顺便说一句,我认为这可能是 https 的重复://stackoverflow.com/questions/1994754/execute-javascript-after-loading-a-mvc-page-using-ajax-beginrouteform但是这个问题被放弃了,没有答案)

I am updating a div with a partial view by using something like this:

<% using (Ajax.BeginForm("Action", "Controller",
               new { id=Model.id },
               new AjaxOptions
               {
                   UpdateTargetId = "divId",
                   InsertionMode = InsertionMode.InsertAfter,
               }))
   {  %>

and its working fine, the returned view gets appened to the div, however I now need to execute a javascript when the post is successful, so I thought: "easy, just add OnSuccess = "MyJsFunc()" " to the AjaxOptions, but after doing this, it stopped working! now the page is refreshed and only the returned partial view is rendered :(, I even tried with a simple Alert("Hi") and its nor working.. how can I get this to work?

(by the way I think this can be a dup of https://stackoverflow.com/questions/1994754/execute-javascript-after-loading-a-mvc-page-using-ajax-beginrouteform but that question got abandoned with no answer)

有什么理由不以正确的方式去做(毕竟我们已经是 2010 年了)?将 MS AJAX 以及依赖于它的所有 Ajax.* 帮助程序转储到它所属的位置并编写正确的代码。虽然在经典 Web 表单中使用 MS AJAX 可能是合理的,因为 UpdatePanel 等,但今天在新的 ASP.NET MVC 应用程序中使用 MS AJAX,尤其是在 Microsoft 完全接受 jQuery 之后,似乎是一个坏主意。

因此,在咆哮之后,这是我的建议:

<% using (Html.BeginForm("Action", "Controller", new { id = Model.id }) { %>

然后在单独的文件中使用 jquery 不显眼地附加提交处理程序:

$(function() {
    $('form').submit(function() {
        $.ajax({
            url: this.action,
            type: this.method,
            success: function(result) {
                // feel free to execute any code 
                // in the success callback
                $('#result').html(result);
            }
        });
        return false;
    });
});

或使用优秀的 jquery 表单插件

$(function() {
    $('form').ajaxForm(function(result) {
        // feel free to execute any code 
        // in the success callback
        $('#result').html(result);
    });
});

这种方法的优点:

  • 不显眼
  • 标记和 javascript 之间清晰分离
  • 缓存 javascript 文件并减少带宽使用

额外好处:没有麻烦。

Any reason for not doing it the right way (after all we are in 2010)? Dump MS AJAX where it belongs along with all the Ajax.* helpers which depend on it and write proper code. While using MS AJAX in classic webforms could have been justified because of the UpdatePanels, etc... doing it in a new ASP.NET MVC application today, especially after Microsoft have fully embraced jQuery, seems like a bad idea.

So after the rant here's my recommendation:

<% using (Html.BeginForm("Action", "Controller", new { id = Model.id }) { %>

and then attach the submit handler unobtrusively using jquery in a separate file:

$(function() {
    $('form').submit(function() {
        $.ajax({
            url: this.action,
            type: this.method,
            success: function(result) {
                // feel free to execute any code 
                // in the success callback
                $('#result').html(result);
            }
        });
        return false;
    });
});

or using the excellent jquery form plugin:

$(function() {
    $('form').ajaxForm(function(result) {
        // feel free to execute any code 
        // in the success callback
        $('#result').html(result);
    });
});

Benefits of this approach:

  • Unobtrusive
  • Clear separation between markup and javascript
  • Caching javascript files and decreasing bandwidth usage

Bonus benefit: no headaches.

我不断环顾四周,在这里找到了答案:

将 Javascript 函数分配给 AjaxOptions OnSuccess 属性会引发错误 - ASP.NET MVC(未选择答案)

引用 阿兹

如果你必须传递任何参数
您可能需要执行的 OnSuccess 事件
这样写函数。

OnSuccess = "function(){exampleFunction('" + param1 + "');}

这对我有用!

I kept looking around and found the answer here:

Assign a Javascript function to AjaxOptions OnSuccess property raise an error - ASP.NET MVC (with the answer that was not selected)

Quoting Atzu

If you have to pass any parameter to
the OnSuccess event you may have to
write the funcion in this way.

OnSuccess = "function(){exampleFunction('" + param1 + "');}

and it worked for me!
