[RESOLVED] JavaScript: Remove <table>blah</table> by macgyver08 on 01-29-2010 at 09:32 PM

I've tried...

code:
string.replace(/<table([^%]+)</table>/ig,"");
...but it doesn't seem to be working.

Are you trying to replace everything including the <table></table>?

Yes, the table tags, and everything they contain.

js code:
// IGNORE -> html = html.replace(/\<table\>.+?\<\/table\>/gi, "");
html = html.replace(/\<table.+?table\>/gi, "");

Should do it.

EDIT:
Changed it to allow for attributes in the table tag such as styles, class, id etc.

Doesn't appear to be working *-)

EDIT: I didn't see your edit before i said it didn't work. Let me try your new one.

New one isn't working either. I don't know if it's your code,or my code that I've  pasted it to though.

I replaced the code with one that removes square brackets and that works, so...it seems like it's your code. Not to insult though, I really appreciate the help, it's just not working.

Yes, it does work. Maybe there is some strange character in the html?

EDIT: Try adding the m modifier to make it run over multiple lines... My test was on a single line basis

RE: JavaScript: Remove <table>blah</table> by macgyver08 on 01-29-2010 at 10:18 PM

Well...it's not working with my code for some reason. I don't know why. What strange character in the HTML could stop it from working?

Also, I'm fairly new to JavaScript, so it's quite likely it's something I've done (or haven't done). Everything else is working though. I just need this one line finished and I think it'll be finished lol

I dunno, experiencing a problem with it too now with a more complicated table
RE: JavaScript: Remove <table>blah</table> by Spunky on 01-29-2010 at 10:40 PM

Line breaks are casuing it to break and I can't get the m modifier to work so we can add an extra replace.

js code:
html = html.replace(/\n/gi, "").replace(/\<table.+?table\>/gi, "");

If you wanted to, you could replace the \n with a unique string so it can be put back together again...

js code:
html = html.replace(/\n/gi, "this-used-to-be-a-line-break").replace(/\<table.+?table\>/gi, "");
html = html.replace(/this-used-to-be-a-line-break/gi, "\n");
// This is just so the source formatting looks good when viewed,
// rather than all being on one line

Hey, I found the problem. It was that what I was testing it on was on multiple lines, so I had to use the metacharacters \r and \n.

code:
html.replace(/<table(.|[\r\n])+?<\/table\>/gi, "");

Thanks for your help though! I really appreciate it :D

Well done, it's a lot more elegant than my solution, but couldn't remember the right syntax for it at the time :p
