jQuery Find and Replace String without HTML ID

May 23, 2012 12:45 pm Published by Leave your thoughts

I’m going to begin posting more day to day pieces of projects I’m working on, in particular solutions to problems I come across along the way.

I’ve been updating an e-commerce checkout page for a client, but since the store uses a hosted solution I often come across parts of pages I have no control over the HTML or content strings. For example, this specific hosted solution allows gift wrapping with a gift message input field, but my client only wishes to provide a gift message, no wrapping. Unfortunately the h4 element always says ‘Gift Wrap’ regardless if wrapping is turned off and messaging turned on. Therefore I used a combination of the jQuery contains selector with the jQuery replaceWith function to replace ‘Gift Wrap’ with ‘Gift Message’. Like so:

$(document).ready(function() { $("h4:contains('Wrap')").replaceWith("<h4>Gift Message</h4>"); });

I could have also used JavaScript find and replace by element ID, but the string I was looking to replace did not have a unique element ID that I could access. The jQuery solution above works around not using an HTML ID and instead focuses on the specific text.
