javascript - Event for a button in modal window

Question

I am new to Javascript and was doing a simple website with a modal dialog. I face problems when invoking an event when clicking a button on the modal window:

my modal code:

<div class="modal fade" id="askus_modal" style="display:none" >  
....
     <div class="modal-footer">
        <button class="btn" data-dismiss="modal" id="askus_cancel">Cancel</button>
        <button class="btn btn-primary" id="askus_submit" type="button">Submit</button>
      </div>
</div>

How do I invoke an alert box(for example) upon the click of Submit button??

I tried:

<script>
    $("#askus_submit").live("click", function(event){
        alert( "GO" ); 
    });
</script>

and

 <script>
     $('#askus_modal').on("click","#askus_submit", function () {
        alert("GO");
  });
 </script>

but both are not working.. can anyone help? I am really new to this

我认为你没有在标题中添加这一行..

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>

并尝试使用您的第一个脚本标记代码..
