Demos: 1.14 needs $.uiBackCompat = true; to use transfer Effect

[melloware]

To use the Transfer effect you have to have $.uiBackCompat = true; and not sure why.

You can see the error on the showcase: https://jqueryui.com/effect/

Pick Transfer and run.

Thanks for the report. See https://api.jqueryui.com/transfer-effect/:

This effect is deprecated, replaced by the .transfer() method.

Trac bug #14749 has more details:

The transfer effect doesn't behave like a normal effect. As such, it should be converted a plugin instead of using the effects API.

We should just remove the effect from the demo, I think:

jquery-ui/demos/effect/default.html

Line 78 in 54f96ee

<option value="transfer">Transfer</option>

And perhaps also its visual test:

jquery-ui/tests/visual/effects/effects.js

Lines 86 to 92 in 54f96ee

	$( "#transfer" ).on( "click", function() {
	$( this )
	.addClass( "current" )
	.effect( "transfer", { to: $( "div" ).eq( 0 ) }, 1000, function() {
	$( this ).removeClass( "current" );
	} );
	} );
