Re: Get data from javascript

For your specific example (not tested):

/replace_image\(([^,]+)/
[download]

/replace_image\(["']([^"']+)/
[download]

should fetch the URL into $1 for you.

The url in the JS is fixed per page, so one per page. I parse lots of pages and want to extract the URL. I tried the code you gave `my $wanted = $page =~ /push_delayed_image\(([^,]+)/; print Dumper $wanted;` [download] But this prints $VAR - 1; not the URL	[reply] [d/l]

You need list context to get the capture groups back. `my ($wanted) = $page =~ /push_delayed_image\(([^,]+)/; # ^ ^` [download] ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l] [select]

Alternately to what Choroba said, you could: `$page =~ /push_delayed_image\(([^,]+)/; my $wanted = $1;` [download] Often, I'm using a conditional, so will do this: `if ($page =~ /push_delayed_image\(([^,]+)/) { my $wanted = $1; ... }` [download]	[reply] [d/l] [select]
