wpColorPicker not working in widgets

[johnstonphilip]

This should be a simple fix. I was creating a widget that uses the new color picker in WordPress 3.5.

It works fine except for when it is first added to a sidebar. I suspect this is because the widget is being added to the sidebar by jquery. The color picker is also applied using jquery - but it isn't able to select the color element because it wasn't part of the DOM when the page loaded.

I don't know where the js code is for the wpColorPicker javascript function, but somewhere in there this should likely be added:
​http://api.jquery.com/live/

.live is deprecated in 1.9 - use .on() or .delegate()

Ah good call. Yes .on() would work. I tested it with other jquery elements in my widget and they work when first added. The same should be applied to wpColorPicker.

This is an implementation issue, not a wpColorPicker issue. It's not magic, it has to be called on the right element at the right time. You could:

1. Put a script element inline inside the widget's widget method, referencing some unique id that you give the text input that you want to turn into a wpColorPicker instance. A bit ugly, but it'll work.
2. If inline code makes you twitch, the cleaner version would go something like:

jQuery('#widgets-right .widgets-sortables').on('sortstop', function(event,ui){
    // run js after widgets are dropped. ui.item contains the dropped item.
    // note that the dropped item could just as easily be a reordering rather
    // than a new widget. Plan your logic accordingly.
});
