Question

所以脚本有效，但看起来很长。我想可能有一些我可以采取的捷径，也许使用数组？但我是JS的新手，而且是jQuery的新手。

它的作用：

我有一个十个问题的列表，我想要一个图形（加号）并在点击减号时切换它。它还将通过幻灯片切换显示答案。

以下是代码：

<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">                                         
   $(document).ready(function() {
   $(".divOne").hide();
   $(".divTwo").hide();
   $(".divThree").hide();
   $(".divFour").hide();
   $(".divFive").hide();
   $(".divSix").hide();
   $(".divSeven").hide();
   $(".divEight").hide();
   $(".divNine").hide();
   $(".divTen").hide();

    $(".bbone").click(function(){
     $(".divOne").slideToggle("slow");
     $("#button1").toggleClass("down");
     });

     $(".bbtwo").click(function(){
     $(".divTwo").slideToggle("slow");
     $("#button2").toggleClass("down");
     });

     $(".bbthree").click(function(){
     $(".divThree").slideToggle("slow");
     $("#button3").toggleClass("down");
     });

     $(".bbfour").click(function(){
     $(".divFour").slideToggle("slow");
     $("#button4").toggleClass("down");
     });

     $(".bbfive").click(function(){
     $(".divFive").slideToggle("slow");
     $("#button5").toggleClass("down");
     });

     $(".bbsix").click(function(){
     $(".divSix").slideToggle("slow");
     $("#button6").toggleClass("down");
     });

     $(".bbseven").click(function(){
     $(".divSeven").slideToggle("slow");
     $("#button7").toggleClass("down");
     });

     $(".bbeight").click(function(){
     $(".divEight").slideToggle("slow");
     $("#button8").toggleClass("down");
     });

     $(".bbnine").click(function(){
     $(".divNine").slideToggle("slow");
     $("#button9").toggleClass("down");
     });

     $(".bbten").click(function(){
     $(".divTen").slideToggle("slow");
     $("#button10").toggleClass("down");
     });

 });                                   
</script>

这是CSS：

<style type="text/css">
body
{
font-family:Verdana, Arial, Helvetica, sans-serif;
}
.divOne, .divTwo, .divThree, .divFour, .divFive, .divSix, .divSeven, .divEight, .divNine, .divTen
{
border:1px solid #CC0000;
background-color:#efefef;
width:580px;
margin-top:5px;
font-size:10px;
padding:5px;
clear:left;
}
.one, .two, .three, .four, .five, .six, .seven, .eight, .nine, .ten
{
padding-left:10px;
text-decoration:none;
color:#CC0000;
font-variant:small-caps;
font-size:14px;
}
.bbone, .bbtwo, .bbthree, .bbfour, .bbfive, .bbsix,.bbseven,.bbeight,.bbnine,.bbten
{
vertical-align:middle;
}
.question
{
height:auto;
background-color:#fff;
margin-bottom:10px;
width:800px;
}
p {
margin:0;
padding:0;
float:left;
width:16px;
height:16px;
background-image:url(images/add.png);
background-repeat:no-repeat;       
    }

p.down {
float:left;
width:16px;
height:16px;
background-image:url(images/delete.png);
background-repeat:no-repeat;
    }

.wwwLink
{
padding-left:20px;
background: transparent url(images/world_go.png) no-repeat center left;
}
</style>

Answer 1

使用此代替您发布的任何jQuery：

$(document).ready(function() {
  $('div.question')
    .children('div').hide().end()
    .children('p').click(function(){
      $(this).toggleClass('down').next().slideToggle("slow");
    });
});

另外，你真的应该巩固你的课程。我将使用这个更新的HTML模式来解答您的所有问题：

<div class="question">
  <p class="button">&nbsp;<a href="#">Myth No. 2:  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam egestas. &nbsp;</a></p>
  <div>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque interdum purus porta urna aliquet consectetur. Maecenas tempus tellus sed augue tincidunt molestie fermentum lorem porttitor. Nam tincidunt elit vitae quam. <br/><br/> 
  <a href="http://stackoverflow.com/questions/ask" target="_blank">Lorem ipsum dolor sit amet, consectetur adipiscing. </a>
  </div>
</div>

您的CSS将遵循以下形式：

.question       { }
.button         { } /* Instead of bbOne, bbTwo, etc*/
.question div   { } /* Instead of divOne, divTwo, etc */
.question div a { } /* Instead of wwwLink */

然后我会使用这个稍微更新的jQuery：

$(document).ready(function() {
  $('div.question')
    .children('div').hide().end()
    .find('p > a').click(function(e){
      $(this)
        .parent().toggleClass('down')
        .next().slideToggle("slow");
      e.preventDefault();
    });
});

Answer 2

类似

$(document).ready(function(){
    $('.question div').hide();
    $('.question p').click(function(){
        $(this).next('div').slideToggle("slow");
        $(this).addClass('down');
    });
});

你也可以修改你的标记并使用jquery ui手风琴：

Answer 3

为你的DIV提供一个公共类，并使用id进行识别，即代替所有内容的所有id，只需在顶级div上有一个id，然后在子ID上使用泛型类名。也避免使用＆amp; nbsp;和＆lt; br /＆gt;标签，但改为使用CSS填充/边距。这些方面的东西：

<div class="question" id="question1">
   <div class="questionText">
      <p class="questionButton"></span>
      <a href="#">Myth No. 1: ...</a>
   </div>
   <div class="questionAnswer">
       ...
   </div>
</div>

这也将简化您的CSS。只需使用常用的类名而不是枚举所有问题。

一般来说，你只需要在类名上使用jQuery，它就会将自己附加到你的所有元素上。同样在jQuery单击处理程序中，您很少需要使用元素的id，您可以使用$（this）来获取当前元素，然后使用遍历函数来获取关联元素。像这样：

   $(document).ready(function() {
       $(".questionAnswer").hide();

       $(".questionButton").click(function(){
           $(this).parent().find(".questionAnswer").slideToggle("slow");
           $(this).toggleClass("down");
       });
   });
