The click event is not working

Can someone point me in the right direction in figuring out why the event in the code below is not working. I tried using firefox but not sure how to troubleshooting this problem using firefox.

Whe开发者_开发问答n I click on the button, nothing happens. I don't see the alert box

 <script type="text/javascript">
 $(document).ready(function()
 {
     $(#saveButton).click(function()
     {
         alert("hello World");
     });
 });
 </script>

 <div id="west" class="ui-layout-west">
    <input id="saveButton" type="button" value="save"></input>
    <div> <ul id="ul_west"></ul> </div>
 </div>

You forgot the quotes around the id.

$('#saveButton').click(function(){
     alert("hello World");
 });

$('#saveButton').click(function() // forgot '
     {
         alert("hello World");
     });
