Here's a useful jQuery snippet that clears the default values of form fields on focus and refills them if no text is entered. It uses the attribute called defaultValue which stores the original value of a form field.
Code: Select all
$(document).ready(function() {
$('input[type=text]').focus(function() {
if($(this).val() == $(this).attr('defaultValue')) {
$(this).val('');
}
})
.blur(function() {
if($(this).val().length == 0) {
$(this).val($(this).attr('defaultValue'));
}
});
});
For example, assume you have a field like this:
Code: Select all
<input type="text" value="Search..." />
When the page loads, the text field will have "Search..." filled in. When you focus on it, this text will disappear (assuming it hasn't already been edited by you). When you leave focus without typing anything, the text will reappear.
