Reading the first 6 characters of a Text-Box

Hi all,

Can anybody tell me how to read the first 6 characters of Text-box?
I think I have to use indexOf but don't know how it works URL

Moin Henk,

indexOf() is not the function that matches your question. The question for indexOf() is "does the string contain this substring".

Your question is "give me the first n characters". This is a job for substr().

(pseudo code!)

n = 5;
sub = "";

value = document.forms.elements[..].value;

if (""!=value && value.length>=n) {
sub = value.substr(0,n);
window.alert(sub);
}
