How can I get this value into my JS code?

[RickB]

Guys, I'm trying to get a value to populate my JS code dynamically. Here's an example.

I need to have a 17 digit VIN number like this "2T1BURHE6EC013995" to populate into my JS code for google adwords in this section "ecomm_prodid: 'REPLACE_WITH_VALUE',".

<script type="text/javascript">
var google_tag_params = {
ecomm_prodid: 'REPLACE_WITH_VALUE',
ecomm_pagetype: 'REPLACE_WITH_VALUE',
ecomm_totalvalue: 'REPLACE_WITH_VALUE',


I have a RegEX that can find the VIN number. var myRegxp = /[A-Z0-9]{17}/

My question is how can I get my VIN number to populate into my JS code dynamically. Can I just place my RegEx Var in and it pull it automatically?

Any pointers or help is greatly appreciated!

You need to apply the RegEX to some text to get the VIN, where is this text coming from ?

Not sure I'd worry about the regex and trying to parse through the page to find a vin or anything like it seems you'd have to do to need a regex to find the info on the page -- Personally, I think I'd just put the vin in a <span> with an id and grab the value with JS.

<span id="vin_number">2T1BURHE6EC013995</span>

<script type="text/javascript">
var vin_num=document.getElementById('vin_number').innerHTML;

var google_tag_params = {
ecomm_prodid: vin_num,
ecomm_pagetype: 'REPLACE_WITH_VALUE',
ecomm_totalvalue: 'REPLACE_WITH_VALUE',

Thank you guys soooo much for your replys. JD, I think your way would work the best for me in this scenario. Using your example, how would I extract only the VIN from this piece of code. Well, let me change that question. Using your example, I know how to extract the inner.html, but it will extract "Vin:xxxxxxxxxx".

<span class="value">6-Speed Automatic</span>
</li>
<li class="exteriorColor">
<strong class="title">
Ext. Color:
</strong>
<span class="value">White Diamond Tricoat</span>
</li>
<li class="vin">
<strong class="title">
VIN:
</strong>
<span class="value">1GYUKCEF6AR250229</span>
</li>
<li class="modelCode">
<strong class="title">
Model Code:
</strong>
<span class="value">6K10706</span>
</li>
<li class="stockNumber">
<strong class="title">
Stock #:
</strong>
<span class="value">00DG438A</span>
</li>
<li class="bodyStyle">
<strong class="title">
Bodystyle:

Can I strip the word "Vin:" and only get the 17 Chars? If I tell it to grab the inner.html, it will get "Vin:xxxxxxxxxxxx". I only need the number.

Also, if you need the full html, here's a page on the website that I manage.

It's really a simple change in your template:

<li class="vin">
<strong class="title">
VIN:
</strong>
<span class="value" id="vin_number">1GYUKCEF6AR250229</span>
</li>

<script>
// As low on the page as you can, but before the call for the ads
var vin_num=document.getElementById('vin_number').innerHTML;

var google_tag_params = {
ecomm_prodid: vin_num,
ecomm_pagetype: 'REPLACE_WITH_VALUE',
ecomm_totalvalue: 'REPLACE_WITH_VALUE'
}
</script>

In PHP you might have to do a bit more work, like:

$id_for_class='';
if($variable_for_the_li_class=='vin') {
$id_for_class=' id="vin_number"';
}

echo '<li class="'.$variable_for_the_li_class.'">
<strong class="title">
VIN:
</strong>
<span class="value"'.$id_for_class.'>1GYUKCEF6AR250229</span>
</li>';

If changing the HTML being generated is an option then consider generating

<script>var vin_num="1GYUKCEF6AR250229";</script>

if NOT in jQuery

var vin_num = $('.vin').find('span').text();

[Readie]

var vinNo = document.getElementsByClassName('vin')[0].getElementsByClassName('value')[0].innerHTML;

If you're not using jQuery and want to make no changes to your templates.

Thank you guys for your help. I'm very green with JS and I'm currently trying to test what you guys recommended. Our dealership pays a company to provide the website platform for us. I know that I can't change the template. As far as if they are using jQuery, there are a few functions on the page using jQuery at the bottom of the page. I don't know if that is affecting the section of the page I'm looking at.

Guys, I need you help again with testing. I'm trying to get the script to write it to the doc with the vin #. That way I know for sure that it's getting the right info and working. Right now, it's not working. What am I doing wrong?

<script>

var vin_num = document.getElementsByClassName('vin')[0].getElementsByClassName('value')[0].innerHTML;

document.write(vin_num);

</script>

Guys,

I apologize. It is working and working correctly. I was using a different program to test the code and program wasn't working correctly. I tried it on w3schools.com and it worked perfect and also in Dreamweaver. Thank you so much for your help.

getElementsByClassName is relatively new to IE ( IE9 ) ensure you are using a library that supports it for older browsers.
