jComponent 20 · jcomponent@20 component Example loaded with jComponent 20

This component executes the code defined in the <script type="text/js"></script> tag.

<script type="text/js">

	// value {Object} a value bound according to the path
	// path {String} a path where the value was bonded
	// type {Number} binding type (0: init, 1: manually, 2: by input, 3: default value)
	// element {jQuery element} a current element
	// datasource {Object}
	// component {jComponent}

</script>

Configuration:

delay {Number} a delay for evaluating code (default: 0)
NEW: datasource {String} a link to the datasource (it will be stored in datasource property)

IMPORTANT:

You need to use <script type="text/js"> or <script type="text/plain">. Don't use the script element without type or with type text|application/javascript because the script will be evaluated by the browser automatically.

Use it with <ui-component name="watcher">. When the component is not loaded yet, jComponent downloads it on first use from the address in DEF.fallback (the Componentator CDN by default). Author: Peter Širka. Source: the Componentator components repository, MIT license.
