Hi,

Using Chrome Dev Tools I have found the CSS selector of a H3 heading.

#container > div.my-table > h3

Open in new window


Within the H3 heading is "Test - some more text here". I need to replace "Test" with "New".

The following attempt results in an 'undefined' error message -

document.body.innerHTML = document.querySelector('#container>div.my-table>h3').replace("Test", "New");

Open in new window


Can anyone see what I am doing wrong?

document.querySelector('#container>div.my-table>h3')
just returns the DOM object. You need to get to this object's text first before attempting to replace it.

Try this:
var theH3Node = document.querySelector('#container>div.my-table>h3');
theH3Node.innerHTML = theH3Node.innerHTML.replace("Test", "New");
