Question

Asked many times, but I can’t get it to work…

I have strings like:

"text!../tmp/widgets/tmp_widget_header.html"

and am trying like this to extract widget_header:

var temps[i] = "text!../tmp/widgets/tmp_widget_header.html";
var thisString = temps[i].regexp(/.*tmp_$.*\.*/) )

but that does not work.

Can someone tell me what I’m doing wrong here?

Thanks!

Answer 1

var s = "text!../tmp/widgets/tmp_widget_header.html",
    re = /\/tmp_([^.]+)\./;

var match = re.exec(s);

if (match)
    alert(match[1]);

This will match:

• a / character
• the characters tmp_
• one or more of any character that is not the . character. These are captured.
• a . character

If a match was found, it will be at index 1 of the resulting Array.
