Sticky default values for an input

Using this example JavaScript you can have a name entry field that contains the text "Enter Name".  The text will go away when the user enters data.  But if they leave the field blank it will go back to "Enter Name".  This can be modified for use with any input field.  Put the JavaScript below in the <head> section of your html page.

<script type="text/javascript">
function focusInput(el) {
if (document.getElementById(el).defaultValue==document.getElementById(el).value) document.getElementById(el).value = "";
}
function blurInput(el) {
if (!document.getElementById(el).value.match(/\w+/)) document.getElementById(el).value = document.getElementById(el).defaultValue;
}
</script>

The <input> tag looks like the one below.  Note the onfocus and onblur function calls.

<input type="text" id="name" style="width: 120px;" value="Enter Name"
onfocus="focusInput(this.id)" onblur="blurInput(this.id)" name="name" maxlength="10" />
