redraw()
Description
Updates the DOM after a change in the application data layer.
You DON'T need to call it if data is modified within the execution context of an event handler defined in a Mithril view, or after request completion when using m.request/m.jsonp.
You DO need to call it in setTimeout/setInterval/requestAnimationFrame callbacks, or callbacks from 3rd party libraries.
Signature
m.redraw()
| Argument | Type | Required | Description |
|---|---|---|---|
| returns | Returns nothing |
How it works
When callbacks outside of Mithril run, you need to notify Mithril's rendering engine that a redraw is needed. External callbacks could be setTimeout/setInterval/requestAnimationFrame callbacks, web socket library callbacks, event handlers in jQuery plugins, third party XHR request callbacks, etc.
To trigger a redraw, call m.redraw(). Note that m.redraw only works if you used m.mount or m.route. If you rendered via m.render, you should use m.render to redraw.
You should not call m.redraw from a lifecycle method. Doing so will result in undefined behavior.
