@Ajax.ActionLink("like", "Like", "Article", new { postId = Model.post.PostId, userName = User.Identity.Name }, new AjaxOptions { OnBegin = "OnBegin" }, new { @class = "like_link" })

function OnBegin()
{
    if( true ) // value from client side. not returning value from server.
    {
        // I dont want to work the link. I want only alert message.
    }
    else
    {
        // Go to controller with parameters.
    }
}

我想是这样上面。 OnBegin不neccesary做到这一点。可能是另一种解决方案。

I want something like above. OnBegin is not neccesary to do it. May be another solutions.

感谢。

推荐答案

OnBegin 应该这样做。简单地返回真或假取决于你是否要执行控制器动作与否：

OnBegin should do it. Simply return true or false depending on whether you want to execute the controller action or not:

function OnBegin() {
    if (true) // value from client side. not returning value from server.
    {
        // I dont want to work the link. I want only alert message.
        alert('alerting some message');
        return false;
    }
    else {
        // Go to controller with parameters.
        return true;
    }
}
