Hi y'all, JS gurues!

I have the following issue:

I execute a page which i defined two functions: lpad and rpad
using String.prototype, like this:
================
String.prototype.lPad = function (n,c) {var i; var a = this.split(''); for (i = 0; i < n - this.length; i++) {a.unshift (c)}; return a.join('')}

String.prototype.rPad = function (n,c) {var i; var a = this.split(''); for (i = 0; i < n - this.length; i++) {a.push (c)}; return a.join('')}
================
My PC has IE 5.5 installed.

But, in the laptop I'm working in right now (it's not mine), it's installed IE 5.0, and when the page reaches the sentence:

miRoot = "ENTERPRISES"; miRoot = miRoot.rPad(66,' ');

a message error is shown with the following msg:

"the object does not accept this property or method"

I isolate the error and i'm 100% sure there it is where is produced, because I tested the page, commenting all the references to xxxxx.rpad() and/or xxxxx.lpad(), and the page works fine, but the texts are not justified - that's the purpose of these li'l functions.

I think the problem is the IE version, but .... what do you have to say about it?


Thanx in advance.

Interesting, indeed. Could you provide some code that shows the code in use?

... test it under IE 5.0 and IE 5.5+

I'm not sure, but perhaps unshift() and push() (as well as pop() and shift()) are the problem. These methods were implemented in JavaScript 1.2.
