    <span class="qty">Quantity</span>
    <br style="clear:both;">

</td>

I want that : after to be Removed/Deleted using Jquery, but i am not getting what handler should be used shall i apply a class to <br> dynamically and do something to it

Answer 1

The jQuery way, without regex:

$('td.quantitybox').contents().filter(function(){       
    return this.nodeType === 3  && // textNode
           $.trim(this.nodeValue) === ":";
}).remove();

Or simply change the textnode to an empty string:

$('td.quantitybox').contents().filter(function(){       
    return this.nodeType === 3  && // textNode
           $.trim(this.nodeValue) === ":";
})[0].nodeValue = "";

If you have multiple textnode with colons- : that you want to remove:

$('td.quantitybox').contents().filter(function() {
    return this.nodeType === 3 && // textNode
    $.trim(this.nodeValue) === ":";
}).each(function() {
    this.nodeValue = "";
});​

If you want to do it with regex and aware of it’s risks:

$('td.quantitybox').html(function(i, old){
    return old.replace(/:\s*</, '<');
});

Note that your HTML code in the question was edited, so I added the white space to the regex so it will work with the initial markup as well….
