Hi,

I have a list menu that is populated by our sales reps. I have a field below the list menu that the user can enter in a percent for the sale. However I need to make it so the list menu can select multiple sales reps and based on how many sales reps are selected I would like the same amount of text fields to populate below. Each one of the sales reps selected in the list menu should auto create the text fields with a sales rep assigned to each field (percent of sale).

Thank you,

Brian

					<cfoutput query="qSalesReps">
					<option value="#record_id#">#first_name# #last_name#</option>
					</cfoutput>
				</select>

<input type="text" name="sales_rep_id">

Not fully understand but try this :


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Untitled Document</title>
<script language="javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script language="javascript">
	$(document).ready(function() {
		$("option", "select[name='SalesReps']").click(function() {
			if( $(this).is(":selected") ) {
				for(var i=0;i<parseInt($("#sales_rep_id").val());i++) $("body").append("<br /><input type='text' name='" + $(this).val() +"' />");
			}
			else {
				$("input[name='" + $(this).val() + "']").remove();
			}
		});
	});
</script>
</head>
<body>
<select name="SalesReps" multiple="multiple"  size="8">
	<option value="record_id1">first_name1 last_name1</option>
	<option value="record_id2">first_name2 last_name2</option>
	<option value="record_id3">first_name3 last_name3</option>
	<option value="record_id4">first_name4 last_name4</option>
</select>
<br />
<input type="text" name="sales_rep_id" id="sales_rep_id" value="10">
<br />
</body>

That's pretty close. I've attached a .PDF of what I need to make it easier. I don't think it's too much more than what you have done. I tried figuring it out from where you left off but I'm just a beginner at jQuery.

Disregard the last .PDF... I made a instruction change that was more clear on this one.

Sweetness! Looks great! jQuery is so cool! Do you have any recommendations of books or other resources for learning jQuery? I'm ok at JavaScript. Would you recommend learning more JS first then getting into jQuery?

Thanks for the advice...

You can learn both at the same time but never forget the origin : Javascript
So 60/40

A book : I can't recommend you one, sorry
A good link(?) : http://www.noupe.com/tutorial/51-best-of-jquery-tutorials-and-examples.html
