joe92 Posted March 3, 2012 Share Posted March 3, 2012 You needn't run two replace commands for what can be done in one. You may have tried including the brackets before but were unaware that they have a special meaning in regular expressions. They represent capturing parenthesis. An extremely useful tool. If you want to match them literally you have to escape them in the pattern with a backslash. Change your replace lines to the following one: tag = tag.replace(/\(\d+\)/g,''); This won't get the 5 in html5 as it is not surrounded by round brackets. Hope that helps you, Joe Link to comment https://forums.phpfreaks.com/topic/258150-deleting-var-from-a-string/#findComment-1323331 Share on other sites More sharing options...
