[javascript] jQuery - Click event on <tr> elements with in a table and getting <td> element values

I have the following HTML in a JSP file:

<div class="custList">
   <table class="dataGrid">
      <c:forEach var="cust" items="${custList}">
         <tr>
            <td>${cust.number}</td>
            <td>${cust.description}</td>
            <td>${cust.type}</td>
            <td>${cust.status}</td>
        </tr>
     </c:forEach>
  </table>
</div>

I need to be able to trigger a 'click' event on each of the dynamically created <tr> tags and also be able to access the values of the <td> tags (of the clicked <tr>) from within the JavaScript function. I have this function already, but sadly it doesn't seem to be working.

$(document).ready(function() {
    $("div.custList > table > tr").live('click', function() {
        alert("You clicked my <tr>!");
        //get <td> element values here!!??
    });
});

Update (Jan 2016): jQuery.live is deprecated (as noted here:http://api.jquery.com/live/)

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.

Try jQuery's delegate() function, like so:

$(document).ready(function(){
    $("div.custList table").delegate('tr', 'click', function() {
        alert("You clicked my <tr>!");
        //get <td> element values here!!??
    });
});

A delegate works in the same way as live() except that live() cannot be applied to chained items, whereas delegate() allows you to specify an element within an element to act on.

<script>
jQuery(document).ready(function() {
    jQuery("tr").click(function(){
       alert("Click! "+ jQuery(this).find('td').html());
    });
});
</script>

$(this).find('td') will give you an array of td's in the tr.

Since TR elements wrap the TD elements, what you're actually clicking is the TD (it then bubbles up to the TR) so you can simplify your selector. Getting the values is easier this way too, the clicked TD is this, the TR that wraps it is this.parent

Change your javascript code to the following:

$(document).ready(function() {
    $(".dataGrid td").click(function() {
        alert("You clicked my <td>!" + $(this).html() + 
              "My TR is:" + $(this).parent("tr").html());
        //get <td> element values here!!??
    });
});?

$("body").on("click", "#tableid tr", function () {
    debugger
    alert($(this).text());
});

$("body").on("click", "#tableid td", function () {
    debugger
    alert($(this).text());
});

This work for me!

$(document).ready(function() {
    $(document).on("click", "#tableId tbody tr", function() {
        //some think
    });
});
