javascript question

[Anon]

Hello,

I want to do following in Javascript: The function has 2 string inputs and it outputs how many times the first string appears in the second string.

I assume there is a function does this but didn't figure out which one?

thanks a lot!

check:

<SCRIPT>
function countSubstr(a_str, a_substr)
{
count=0;
sub_index = a_str.indexOf(a_substr, 0);
while ( sub_index != -1)
{
count ++;
sub_index = a_str.indexOf(a_substr, sub_index+1);

    };
    return count;

}
sub1 = 'ab';
sub2 = 'abc';
bigstr = 'abdabcabcdab';
window.alert(sub1 + ' in ' + bigstr + "\n\n" + countSubstr(bigstr, sub1));
window.alert(sub2 + ' in ' + bigstr + "\n\n" + countSubstr(bigstr, sub2));
</SCRIPT>
