我有以下 ajax.actionlink。我想将点击事件添加到此操作链接。我怎样才能做到这一点

<%= Ajax.ActionLink("text", "textaction", new { param = 1}, new AjaxOptions
                            {                                   
                                OnSuccess = "updatePlaceholder",                                
                                UpdateTargetId = "result"
                            })%>

由于您正在使用 Ajax.ActionLink 帮助器方法，因此单击事件处理程序已添加到此链接。此单击事件处理程序将取消默认操作并向此链接指向的地址发送 AJAX 请求。您可以尝试设置 OnBegin 选项。

如果您在项目中使用 jquery，则可以有一个正常链接（无需通过 Ajax.ActionLink 帮助器将所有 javascript 添加到您的标记中）：

<%= Html.ActionLink(
    "text", 
    "textaction",
    new { param = 1 },
    new { id = "mylink" })
%>

然后在一个单独的链接中javascript 文件附加点击事件处理程序：

$(function() {
    $('#mylink').click(function() {
        // here you could execute some custom code
        // before sending the AJAX request
        $('#result').load(this.href, function() {
            // success function
        });
        return false;
    });
});

这种方式将实现标记和 javascript 文件之间的清晰分离。由于 javascript 将位于单独的文件中，这些文件将由客户端浏览器缓存，因此您将减少带宽。

The click event handler is already added to this link because you are using the Ajax.ActionLink helper method. This click event handler will cancel the default action and send an AJAX request to the address this link is pointing to. You may try setting the OnBegin option.

And if you use jquery in your project you could have a normal link (without all the javascript added to your markup by the Ajax.ActionLink helper):

<%= Html.ActionLink(
    "text", 
    "textaction",
    new { param = 1 },
    new { id = "mylink" })
%>

and then in a separate javascript file attach the click event handler:

$(function() {
    $('#mylink').click(function() {
        // here you could execute some custom code
        // before sending the AJAX request
        $('#result').load(this.href, function() {
            // success function
        });
        return false;
    });
});

This way will achieve a clear separation between your markup and javascript files. As javascript will be in separate files which will be cached by client browser you will reduce bandwidth.
