Onclick event to remove default value in a text input field

Question

I have an input field:

How would I get it to remove the pre-defined text (Enter Your Name

Answer 1

This should do it:

HTML

JavaScript

function blankDefault(_text, _this) {
    if(_text == _this.value)
        _this.value = '';
}

There are better/less obtrusive ways though, but this will get the job done.
