Daniel’s one worked a treat for me with jQuery 1.3.2 and looks more rock solid.

Thank you for your contribution

line 10 was the one causing the issue, changed it to this:
$(this).val(phvalue);
$(this).addClass(options.css_class);

For some reason this script crashes IE and firefox doesn’t like it. So I’ve modified the script a lil, here it is below:

It also has a form submit handler to remove the placeholder value on submit.

(function($) {
$.fn.placeholder = function(options) {
var defaults = {css_class: “placeholder”};
var options = $.extend(defaults, options);
this.each(function() {

var phvalue = $(this).attr(“placeholder”);
var currvalue = $(this).attr(“value”);
if (currvalue == “”) {
$(this).val(phvalue);
$(this).addClass(options.css_class);
}
$(this).focusin(function(){
var ph = $(this).attr(“placeholder”);
if (ph == $(this).val()) {
$(this).val(“”).removeClass(options.css_class);
}
});

$(this).focusout(function(){
var ph = $(this).attr(“placeholder”);
if ($(this).val() == “”) {
$(this).val(ph).addClass(options.css_class);
}
});

});

$(‘form’).submit(function(){
$(‘input[type=text]‘, this).each(function(){
if($(this).val()==$(this).attr(‘placeholder’)) $(this).val(”);
});
});

return this;
};
})(jQuery);

I made a version that also supports input type=”password” (even for IE that doesn’t allow changing input type for showing a placeholder).
