jQuery无响应点击事件

我正在尝试在jQuery中构建一个基本滑块。我有5个主要部分显示在页面上,当您将鼠标悬停在其容器div上时,会在第一个和最后一个元素上弹出箭头。

我的下一步是编写一个代码,用于在数组中存储div(左侧或右侧,具体取决于点击侧),并将其从DOM中删除。但是,我在点击事件时遇到了麻烦。

这是我的css:

.left_arrow_background {
 height: 175px;
width: 65px;
/* background:url(../images/left-arrow.png) no-repeat; */
background:#ccc;
opacity: .9;
position: absolute;
cursor: pointer;
z-index: 2;
}

.right_arrow_background {
height: 175px;
width: 65px;
/* background:url(../images/right-arrow.png) no-repeat;*/
background:#ccc;
z-index: 2;
opacity: .9;
position: relative;
left:890px;
cursor: pointer;
}
.boomers_scroller {
height:275px;
padding-left:1px;
display:block;
border-bottom-width: 1px;
border-bottom-style: solid;
border-bottom-color: #CCC;
    overflow:hidden;
}
.all-boomers {
display: block;
float: left;
height: 225px;
margin-bottom: 20px;
margin-left: 20px;
width: 175px;
}

输出的HTML:

<div class="all-boomers">
<a href="/boomers/profile/id/2"><img src="/images/users/medium_thumbs/4fa44866c3561.jpg" alt=""/></a>
      <p class="boomers_name">PC Guy</p>
      <p class="activity_name">IT Guy PC Repair</p>
    </div>
<!-- three more identical section here -->
<div class="all-boomers">
<a href="/boomers/profile/id/6"><img src="/images/users/medium_thumbs/4fa62dff64c44.jpg" alt=""/></a>
      <p class="boomers_name">Cruella Deville</p>
      <p class="activity_name">Dalmation Dog-Sitter</p>
    </div>

即使从样式表中删除z-index,我似乎也无法记录点击事件。到目前为止,这是我的js文件:

$(document).ready(function() {

  var boomers = $('.all-boomers');
  var boomersLength = boomers.length;
  var boomersContainer = {};
  $(".all-boomers:eq(4)").attr('id','right-boomer');
  $(".all-boomers:eq(0)").removeClass("all-boomers").addClass("one-fifth first").attr('id','left-boomer');
  var image_left = '<div class="left_arrow_background"></div>';
  var image_right = '<div class="right_arrow_background"></div>';

  $(".boomers_scroller").hover(  
    function(){
        $(image_left).insertBefore('#left-boomer');
        $(image_right).insertAfter('#right-boomer');
    },
    function(){
        $('.left_arrow_background').remove();
        $('.right_arrow_background').remove();
    });

  $("div.left_arrow_background").click(function(){
    var left_boomer = $('#left-boomer').children();
    // store left_boomer in boomerscontainer, then remove it from dom
    console.log('clicked!');

  });
 });

这不只是点击事件......我也尝试了其他鼠标事件,没有任何事情触发控制台测试消息,或者如果我将代码置于.click函数中,它将不会触发代码。

编辑:添加了第4个(相关的CSS样式)

你忘了关闭ready()函数(或者在粘贴之前复制它:) 再加一个});在这段代码的底部。 这是孤立的: http://jsfiddle.net/Q3rDz/

固定!当我点击时,悬停事件仍然存在,因此将click事件嵌套在悬停事件中会清除问题。

$(document).ready(function() {
var boomers = $('.all-boomers');
var boomersLength = boomers.length;
var boomersContainer = {};
$(".all-boomers:eq(4)").attr('id','right-boomer');
$(".all-boomers:eq(0)").removeClass("all-boomers").addClass("one-fifth first").attr('id','left-boomer');
var image_left = '<div class="left_arrow_background"></div>';
var image_right = '<div class="right_arrow_background"></div>';
$(".boomers_scroller").hover(       function(){ 
     $(image_left).insertBefore('#left-boomer');
     $(image_right).insertAfter('#right-boomer');
     $("div.left_arrow_background").click(function(){
           var left_boomer = $('#left-boomer').children();
          // store left_boomer in boomerscontainer, then remove it from dom
          console.log('clicked!');    });
 }, 
function(){ 
    $('.left_arrow_background').remove();
     $('.right_arrow_background').remove();
 });
 });
