string must have specific length

I want the value of a variable to always have 6 characters. If it has less, I want zero’s added to the end, and if it has more I just want the end of it cut off. Any suggestions on how to do it?

@heavenly_blueauthorAug 03.2004 — would this work for if it's less than 6 characters long?

[CODE]
while (theVariable.length < 6){theVariable = theVariable + "0";}
[/CODE]

@heavenly_blueauthorAug 03.2004 — and possibly this for the other?

[CODE]
if (theVariable.length > 6){theVariable.length = 6;}
[/CODE]

i'm just making this up as i go along, but it looks like it might work.

@JonaAug 03.2004 — [font=trebuchet ms]Quite surely, it is, for the first.[/font]

@JonaAug 03.2004 — [font=trebuchet ms]For the second, use the following.[/font]

<i>
</i>&lt;script type="text/javascrpit"&gt;
var k = "This is more than six";
if(k.length &gt; 6){
k = k.substr(0, 6);
}
alert(k);
&lt;/script&gt;

Success!
