Yeah,
I´m wrong. And without the filter inside the plugin, we can use with
textarea too. So, the new code is here. Thanks. I´m learning so much
with these discussion.
/**
* jQuery resetDefaultValue plugin
* @version 0.9.1
* @author Leandro Vieira Pinho <[EMAIL PROTECTED]>
* How to use
* $(function() {
* $('input').resetDefaultValue(); // for all input elements
* $('input.className').resetDefaultValue(); // for some elements
* $('#q').resetDefaultValue(); // for a especific element
* $('[EMAIL PROTECTED]').resetDefaultValue(); // avoid button/reset/
submit buttons
* $('textarea').resetDefaultValue(); // work with textarea too
* });
* ChangeLog
* 0.1 - First relase
* 0.2 - Filter input elements with type igual text, just it.
* 0.9 - Rewrite all the plugin code. Thanks to Klaus Hartl [
http://groups.google.com/group/jquery-en/browse_thread/thread/5ca50fd021062331
]
* 0.9.1 - Doesn´t do the filter inside the plugin

jQuery.fn.resetDefaultValue = function() {
function _clearDefaultValue() {
var _$ = $(this);
if ( _$.val() == this.defaultValue ) { _$.val(''); }
};
function _resetDefaultValue() {
var _$ = $(this);
if ( _$.val() == '' ) { _$.val(this.defaultValue); }
};
return
this.click(_clearDefaultValue).focus(_clearDefaultValue).blur(_resetDefaultValue);
}
