Get default value of an input using jQuery

Question

$(".box_yazi2").each(function () {
    var default_value = this.value;
    $(this).css('color', '#555'); // this could be in the style sheet instead
    $(this).focus(function () {
        if (this.value == default_value) {
            this.value = '';
            $(this).css('color', '#000');
        }
    });
    $(this).blur(function () {
        if (this.value == '') {
            $(this).css('color', '#555');
            this.value = default_value;
        }
    });
});

This function of default value of input doesnt work in FF, but perfectly works in IE and ofcourse the input itself looks like this:

<input type="text" class="box_yazi2" id="konu" name="konu" value="Boş" />

Answer 1

Just use the defaultValue property:

var default_value = $(this).prop("defaultValue");

Or:

var default_value = this.defaultValue;
