下面的javascript jQuery代码可以工作,除了我想在按钮的状态中添加2个功能.

>当用户单击其中一个按钮时,未单击的另一个按钮将获得一个新类(外观).
>两个按钮的状态都应该变为无法点击.

[div id="1" class="__button_image"] [/div]
[div id="2" class="__button_image"] [/div]

$("div.__button_image").mouseover(function () {
    $(this).addClass("__button_image_hover");
});

$("div.__button_image").mouseout(function () {
    jq(this).removeClass("__button_image_hover");
});

$("div.__button_image").click(function () { 
    $(this).removeClass("__button_image_hover");
    $(this).addClass("__button_image_clicked");

    jQuery.get('/do/request');        
});

解决方法:

这是我最后的代码：

$("div.__button_image").mouseover(function () {
    $(this).addClass("__button_image_hover");
});

$("div.__button_image").mouseout(function () {
    $(this).removeClass("__button_image_hover");
});

$("div.__button_image").click(function () {

    /** change button look to 'clicked' */
    $(this).addClass("__button_image_clicked");

    /** get the id of the current button */
    b_id = $(this).attr('id');

    /** unbind both vote buttons for *no* interaction */
    $("div.__button_image").unbind('click');
    $("div.__button_image").unbind('mouseover');
    $("div.__button_image").unbind('mouseout');

    /**
     * wire the .each function to iterate the classes 
     * so we can change the look of the one that was 
     * not clicked.
    */
    $('div.__button_image').each(function() {
      button_id = $(this).attr('id');
      if(button_id!=b_id) {
         $('#'+button_id).removeClass("__button_image");
         $('#'+button_id).addClass("__button_image_gray");  

    }
});

jQuery.get('/do/request?id='+b_id); 
$(this).parent().css('cursor', 'default');
