How to extract the number using regular expressions in JS?

Hi,
Can you please let me know how I can extract the "anynumber" from the following string?

<TD ALIGN=RIGHT NOWRAP><anystring HREF='/atv-bin/mytree.cgi?line=anystring&job=anynumber' TARGET=middle_frame

Open in new window


An example case:
The number that I want to assign to a variable using regular expressions is 515595:
<TD ALIGN=RIGHT NOWRAP><C HREF='/atv-bin/mytree.cgi?line=C&job=51595' TARGET=middle_frame

Open in new window


How can I do that?

Thanks,

//or...

var sample = "<TD ALIGN=RIGHT NOWRAP><C HREF='/atv-bin/mytree.cgi?line=C&job=51595' TARGET=middle_frame ";
var digits = sample.replace( /^.*job=(\d+).*$/, "$1" );
alert( digits );

digits = sample.match( /(?:job=)(\d+)/ );
alert( (digits)? digits[1] : 0 );

Why did you use replace?

Can we use match as well? Because I don't want to replace it with something else.

Thanks,

Well it wouldn't actually replace the string unless you assigned the result back to the source string. String replacment in JS is not in-place. This means when you call the replacement function, the resulting, replaced string is returned from the function and the original string is untouched. Many languages perform this kind of string handling.

As an example:
var source = "Hello World!"

alert(source);                   // displays: Hello World!
alert(source.replace(/l/, ''));  // displays: Heo Word!
alert(source);                   // displays: Hello World!
source = source.replace(/l/, ''));
alert(source);                   // displays: Heo Word!
