how to update all occurrence of key value

Question

var someString = "style="height: 247px; width: 329px;" rel="height: 247px; width: 329px;" ";

how to update width value from 329px to 500px using regular expression in javascript.

i'm able to get the width value by using

reg = /width:\s(\d*)/;
someString.match(reg)[1];

but how to update all width values ?

If you need to update some text, it means you need a `replace` method. And your regex is almost complete, you do not need capturing parentheses, and you can use `\d+` to match one or more digits. — Wiktor Stribiżew, Jul 02 '16 at 17:38

var someString = "style=\"height: 247px; width: 329px;\" rel=\"height: 247px; width: 329px;\" ";
someString.replace(/width:\s(\d*px)/g,'500px')

I am correcting a bit:

someString.replace(/width:\s(\d*px)/g,'width: 500px')
