[eluser]Innovative[/eluser]
Hi,
I am beginner so need your help.
I have a form with phone field, if the user enters 0 as first digit then i need to trim that 0 when the field looses focus and also a gmail like or any fancy alert informing abt the change is to be accomplished. Pls suggest.

Add zero to it.

005 + 0 = 5

Javascript has no trim function but you can get the same
effect by using the function below.

(german site)

Code:

<scr+ipt language="javascript" type="text/java+scr+ipt">
function trim (your_string)
{
    return your_string.replace (/^\s+/, '').replace (/\s+$/, '');
}
</scr+ipt>

Try onblur event in your form

005 + 0 = 5[/quote]
It would work in PHP, but not in JS (because + is also the concatenation operator)

Usually, I multiply by 1, or subtract 0.

Typecasting guys.

Code:

echo '005'; // 005
echo (int) '005'; // 5
