Question

@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.
    }
}

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

Thanks.

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;
    }
}
