autoPopulate 0.1 - Automatically populate form fields using a bookmarklet

/ Published in: JavaScript

I\'m constantly testing forms over and over for one reason or another, and am fed up with making a typo and autocomplete not populating all the data, so I made this little snippet. It searches for form elements on the page (input, textarea and select) and using regular expressions, tries to match the field name and populate the data as best it can. There\'s also a generator so instead of the random test data I\'ve provided you can generate your own.\r\n\r\nDemo:\r\n[http://www.dom111.co.uk/files/autoPopulate/](http://www.dom111.co.uk/files/autoPopulate/)\r\n\r\nGenerator:\r\n[http://www.dom111.co.uk/files/autoPopulate/generate.html](http://www.dom111.co.uk/files/autoPopulate/generate.html)
