Huh! Have you try to use TM Billing System with Firefox? Yeah! It doesn’t works well on Firefox. When trying to view my latest bill statement, it gives me error (looks like no action at all).

Grrr… Then, with a power of Firefox, I use Firebug Extension to debug it. The debugger shows a message “invoiceObject is not defined“. As expected, javascript problem.

When looking at the source code:

<span class="sourceRowText" /> <p align="left"><select size="1" name="invoiceObject"> <option value="0.0.0.1 /invoice 5583702330 0">24 Dis 2006</option> <option value="0.0.0.1 /invoice 5484966728 0">24 Nov 2006</option> <option value="0.0.0.1 /invoice 5387829069 0">24 Okt 2006</option> </select></p> <div class="sourceRow"><a class="sourceLine"> 99</a><span class="sourceRowText"> </span></div> <div class="sourceRow"><a class="sourceLine">103</a><span class="sourceRowText"> <p align="center"><input type="button" onclick="window.location = 'invoiceTemplate.jsp?language=BM&invoicePoid='+invoiceObject.value" value="Versi Bahasa Malaysia" name="getInvoiceBM" /></p> </span></div> <div class="sourceRow"><a class="sourceLine">104</a><span class="sourceRowText"> </span></div> <div class="sourceRow"><a class="sourceLine">106</a><span class="sourceRowText"> <p align="center"><input type="button" onclick="window.location = 'invoiceTemplate.jsp?language=ENG&invoicePoid='+invoiceObject.value" value="English Version" name="getInvoiceENG" /></p> </span></div> <div class="sourceRow"><a class="sourceLine">107</a><span class="sourceRowText"> </span></div> <p align="left">

A suggestion to fix this is to replace

invoiceObject.value

WITH

document.getElementsByName(’invoiceObject’)[0].value

getElementsByName are specifically designed for fast and efficient dynamic object property changes from JavaScript. The sweetest part of it is, these methods will not only go dig up all the tags with a certain name attribute or tag name, they’ll slap them into convenient arrays for us. Now, that’s service!

I believe this fix should works with all browser. TMnet, please modify the code to make the system firefox friendly.
