Choose any symbol in javascript regex

 /start(.*)end/

will match FOO in startFOOend and BARendBAZ in startBARendBAZend.

 /start(.*?)end/

will match FOO in startFOOend and BAR in startBARendBAZend.

The dot matches anything except a newline symbol (\n). If you want to capture newlines as well, replace dot with [\s\S]. Also, if you don't allow the match to be empty (as in startend), use + instead of *.

See http://www.regular-expressions.info/reference.html for more info.

I'm not sure I understand what you mean by "symbol", if you mean anything, that's what the dot . will match

Are you trying to do this?

var regex = /start(.*)end/; 
var templateCode = myString.match(regex);
