Get iframe name 1

[Ruriko]

Hi I'm a newbie at javascript and I was wondering how can I extract the iframe name using regex only? so for example if the string value contains:

<DIV style="MARGIN-TOP: 0px; WIDTH: 670px; HEIGHT: 210px; VISIBILITY: visible; MARGIN-LEFT: -335px; TOP: 48px" id=TB_window><DIV id=TB_title>  <DIV id=TB_ajaxWindowTitle>Add Media</DIV>  <DIV id=TB_closeAjaxWindow><A id=TB_closeWindowButton title=Close href="#" jQuery172014112867239284427="140"><IMG src="[URL unfurl="true"]http://www.gorgeoushentai.com/wp-includes/js/thickbox/tb-close.png"></A></DIV></DIV><IFRAME[/URL] style="WIDTH: 670px; HEIGHT: 180px" id=TB_iframeContent onload=tb_showIframe() src="[URL unfurl="true"]http://www.gorgeoushentai.com/wp-admin/media-upload.php?post_id=168&"[/URL] frameBorder=0 name=TB_iframeContent656 hspace=0>This feature requires inline frames. You have iframes disabled or your browser does not support them.</IFRAME></DIV>

then it would extract TB_iframeContent656

Hi

For your sample input this will work, but note that regular expressions are not suitable for parsing complex structured data :

matchlist[teal]=[/teal]yourstring[teal].[/teal][COLOR=darkgoldenrod]match[/color][teal]([/teal][fuchsia]/<iframe\b[^>]+\bname=["']?(.+?)\b/i[/fuchsia][teal])[/teal]
[b]if[/b] [teal]([/teal]matchlist[teal])[/teal] iframename[teal]=[/teal]matchlist[teal][[/teal][purple]1[/purple][teal]][/teal]

Using a regular expression seems a little arcane, bordering on bizarre to say the least.

surely

var IFname = document.getElementsByTagName('iframe')[0].name;

would do perfectly well. Assuming ther is only one iFrame which your question does imply.

Hi

Chris, that may not be enough, given the OP wrote (s)he has a "string value".

True, but tempered with the the point that javascript and iframes are only likely to occur in the context of a web browser, it seems like a reasonable assumption that the TS as a

newbie at javascript

is asking the wrong question.


And then the number of time it has asked the same question and the wording it may also be a coursework question from yet another lazy student.

AND

there is this one, thread329-1696839 lurking in the vBScript board which I hadn't even noticed was by the same person, it all smells rather "studenty" to me.
