How can I use javascript regexp to do a case insensitive, global search and replace on a string with the following pattern:
[media id="5"] or [Media id=5]
and replace entirely with:
http://someurl/?somevar=THE_ID_FROM_THE_PATTERN
So basically, something like this:
var mystring = '<img src="[media id=5]" />';
Should be converted to:
var newstring = '<img src="http://someurl/?somevar=5" />';
You need to capture the number, using parentheses, and add it back in with $1 when you replace. Also, based on your example, it should be case insensitive (//i) and the quotation marks are optional.
var mystring = '<img src="[media id=5]" />';
var re = /\[media id="?(\d+)"?\]/gi;
mystring.replace(re, "http://someurl/?somevar=$1");
You can use:
var mystring = '<img src="[media id=5]" />';
mystring.replace(/\[media id=5\]/gi, 'http://someurl/?somevar=5').toString();
AND/OR
var mystring = '<img src="[media id=\"5\"]" />';
mystring.replace(/\[media id=\"5\"\]/gi, 'http://someurl/?somevar=5').toString();
var regexp=/\[media id="5"\]/gi;
The right way, I think, would be something like this:
var regexp = /\[[mM]edia\ id\=\"\d+\"\]/g;
var mystring = '<img src="[media id=5]" />';
var newstring = mystring.replace(regexp, "http://someurl/?somevar=$1");
regexp are not optional. Tack on a question mark to them to allow 0 or 1 occurrence.
