Empty value of textbox once active

[leetee4000]

I want to have a value in a textbox so that the user can see what needs to be entered. When the user selects the box to start entering details I want the it to empty. I have seen this used many times but don't know how this is achieved?

Many thanks

Please do not cross post.

See if this basic example helps:

<script type="text/javascript">
window.onload=function(){
var inp=document.getElementById('inp'), // Set the input element's ID.
text='Search...'; // Default input text's value. This should match on the value of your value attribute.
inp.onfocus = function()
	{this.style.color='#222';this.value=(this.value==text)?'':this.value;}
inp.onblur= function()
	{
	if(this.value=='')
		{
		this.value=text;
		this.style.color='#aaa';
		}
	else this.value;
	}
}
</script>
<input type="text" value="Search..." id="inp" style="color:#aaa;">
