如何精简以下jquery代码片段

Question

I have the following jQuery code and it works fine but it loads very slowly. i am not a pro in jQuery so can anyone help me make following code snippet more concise? I will appreciate this.

jQuery(document).ready(function() {
    // colorpicker field
    jQuery('.twb_btn_color, .twb_spam_clr, .twb_btn_txt_color, .twb_bg_color, .twb_main_title_color, .twb_sub_title_color')
        .each(function(){
            var $this = jQuery(this),
                id = $this.attr('rel');
            $this.farbtastic('#' + id).hide();
            jQuery('.twb, .twb-title').click(function() {
                jQuery('.twb_btn_color').fadeIn('medium').siblings("div").hide();
            });
            jQuery('.twb-spam, .twb-spam-title').click(function() {
                jQuery('.twb_spam_clr').fadeIn('medium').siblings("div").hide();
            });
            jQuery('.twb-btn-txt-color, .twb-btn-txt-color-title').click(function() {
                jQuery('.twb_btn_txt_color').fadeIn('medium').siblings("div").hide();
            });
            jQuery('.twb-bg-color, .twb-bg-color-title').click(function() {
                jQuery('.twb_bg_color').fadeIn('medium').siblings("div").hide();
            });
            jQuery('.twb-main-title-color, .twb-main-title-color').click(function() {
                    jQuery('.twb_main_title_color').fadeIn('medium').siblings("div").hide();
            });
            jQuery('.twb-sub-title-color, .twb-sub-title-color').click(function() {
                jQuery('.twb_sub_title_color').fadeIn('medium').siblings("div").hide();
            });
    });
});

The typical way of handling this is to give all the elements that you want to perform the same action on the same class name .

Also, so that you don't have to bind the event to each of them, you can delegate the event on a common parent, in this case we'll use body :

$('body').on('click', '.common-class-name', function () {
   $(this).fadeIn('medium').siblings("div").hide();
});

This requires that you give all the elements the same class name. You can then reference the one that has been clicked with $(this) .
