Usage

The module will prefill all webform form elements as soon as it is enabled.

Use CSS classes for excluding/including parts of your forms.

You can use the classes .webform-prefill-exclude and .webform-prefill-include to blacklist or whitelist parts of your forms. By default the whole form is whitelisted.

You can use a weform component’s wrapper classes to exclude or include components easily.

Use URL fragments to add values to the prefill store

You can add prefill values to the store by adding a special URL fragment to your links. For example:

You enter the page the page using the URL https://example.com#p:name=Alice.
Later in this session you navigate to a webform.
The webform contains a textfield component with the form key name which is prefilled with the value “Alice”.

You can still use fragments for something else by separating the prefill part (p:…) using from the rest of the fragment using a semi-colon ;. That means if you enter the website using https://example.com?#anchor;p:name=Alice the prefill value is removed from the URL after the JavaScript is done and you see the page as if you had entered https://example.com?#anchor instead.

Browser compatibility

The JavaScript in this module is compatible with IE 11. However the required polyfills are not bundled. If you want to support these browsers you’ll neet to load an appropriate polyfill.
