No error, but no value. Why?

Here's my code:

<div id="helper" style="display:none;"></div>
<input id="ord_reviewOrder_submit" type="button" class="btn_base btn_green_60" value="Submit" onclick="$('#ord_reviewOrderError').slideUp().html('');
       if($('#ord_deliveryMethod').val().length == 0 || $('#ord_deliveryCost').val().length == 0)
       var amount = $('#helper').val();
       $('#ord_reviewOrderError').append('A delivery method must be selected to process the order.<br/>');
       [b]$('#ord_reviewOrderError').append('$('#helper).val()');[/b]

What you're looking at is a part of a page that I'm being asked to troubleshoot.

The solution I'm trying to engineer will be looking for the value the API is going to be putting in the "helper" div.

Ultimately, I want to be able to evaluate that value, but for now I'm just trying to reproduce it and I can't get it to show up in the line that I have in bold.

There's no error, but there's no value either.

When I look at the source code, I can see this:

[code]<div id="helper">1000</div>

But I won't see "1000" in the "ord_reviewOrderError" div which is located toward the bottom of the page.

No error, but no value.

What am I missing?

HTML code:

<div id="helper"  style="display:none;" ></div>
<input type="button" id="ord_reviewOrder_submit"  value="submit">

Open in new window

JQuery script

 $('#ord_reviewOrder_submit').on('click',function(){
       $('#ord_reviewOrderError').slideUp().html('');
       if($('#ord_deliveryMethod').val().length === 0 || $('#ord_deliveryCost').val().length === 0){
       var amount = $('#helper').parseInt(text());
       $('#ord_reviewOrderError').append('A delivery method must be selected to process the order.<br/>');
       $('#ord_reviewOrderError').append($('#helper').val());
       }
  });

Just to highlight the problem

$('#ord_reviewOrderError').append('$('#helper).val()');

Open in new window

Look at what is being passed to the append

'$('#helper).val()'

Open in new window

This is a string - it is in quotes so the actual string $('#helper).val() is going to be appended - not the value of #helper

As suggested above you need to pass in the actual value i.e. remove the quotes.

Thank you, guys! It was the "text" dynamic as opposed to "val." That made the difference!
