react-trigger-change

Library for triggering React's synthetic change events on input, textarea and select elements.

In production builds of React ReactTestUtils.Simulate doesn't work because of dead code elimination. There is no other built-in way to dispatch synthetic change events.

This module is a hack and is tightly coupled with React's implementation details. Not intended for production use. Useful for end-to-end testing and debugging.

Install

With npm:

``
npm install react-trigger-change --save-dev
`

From a CDN:

`HTML

`

Use

`JSX
reactTriggerChange(DOMElement);
`

DOMElement - native DOM element, will be the target of change event.

One way to obtain a DOM element in React is to use ref attribute:

`JSX
let node;
ReactDOM.render(
onChange={() => console.log('changed')}
ref={(input) => { node = input; }}
/>,
mountNode
);

reactTriggerChange(node); // 'changed' is logged
`

Test

Build the browser bundle:

`
npm install
npm run build
`

Open test/test.html in the browser.
Specify React version with a query string, for example:

?version=15.4.2 for React v15.4.2
?version=16.0.0-alpha.6&min=1` for minified React v16.0.0-alpha.6
