Question

So I have this contact form and I want to put text inside each input, when the user clicks on it the text disappears so they can add stuff – when the user clicks on something else it reappears. I have done this with labels and negative margin along with position relative. I plan on adding an onclick function to each input.

My question is – is there a function that is like Offclick()? Or something similiar to mouseOver() and MouseOut()?

Answer 1

Text inputs have onblur and select boxes have onchange events that can be wired into.

<input type="text" id="UserName" name="UserName" value="Placeholder ..." />

<script type="text/javascript">
var el = document.getElementById("UserName");
var original_text = el.value;
el.onblur = function() {
    // `this` is set to the input element by the browser
    if ( ! this.value ) {
        this.value = original_text;
    }
};
</script>

With jQuery, it is even easier:

var el = $("#UserName");
var original_text = el.val();
el.blur(function(){
    // `this` is set to the input element by jQuery.
    if ( ! this.value ) {
        this.value = original_text;
    }
 });
