Specify when validation occurs

By default, the Validation Text Area widget validates when the user clicks the submit button. You can, however, set two other options: blur or change. The validateOn:["blur"] parameter causes the widget to validate whenever the user clicks outside the text area. The validateOn:["change"] parameter causes the widget to validate as the user changes text inside the text area.

To specify when validation occurs, add a validateOn parameter to the constructor as follows:

<script type="text/javascript">
	var ta1 = new Spry.Widget.ValidationTextarea("sprytextarea1", {validateOn:["blur"]});
</script>

As a convenience, you can discard the brackets if your validateOn parameter contains a single value (for example, validateOn: "blur"). If the parameter contains both values, however (validateOn:["blur", "change"]), include brackets in the syntax.
