How Can You Access Visualforce Components Values Into A Javascript?

Answer»

Using Component GLOBAL variable, we can ACCESS visualforce COMPONENTS in javascript. Let us suppose, we want to use id of an apex field with id=”afield”.

So, we can use the {!$Component.afield} SYNTAX to use PROPERTIES of the field in javascript.

Let us suppose, we want to store the field’s value in java script, then we can use like below:

<script>

Var a =’ document.getElementById('{!$component.afield}').value’;

</script>
