jquery操作div同一类

Question

例如

<div id="red">
<div class="one"></div>
<div class="two"></div>
<div class="three"></div>
</div>
<div id="blue">
<div id="sub" class="one"></div>
<div id="sub" class="two"></div>
<div id="sub" class="three"></div>
</div>

当我点击.one时，显示#sub.one，相同的类名。感谢

Answer 1

首先，您不应该在页面上重复id，所以我重新构造了您的HTML:

<div id="red">
    <div class="one"></div>
    <div class="two"></div>
    <div class="three"></div>
</div>
<div id="blue" class="sub">
    <div class="one"></div>
    <div class="two"></div>
    <div class="three"></div>
</div>

然后，您可以执行以下操作：

$('#red').on('click', 'div', function(ev){
    $('.sub div').hide();
    $('.sub .' + $(this).attr('class')).show();
});

Answer 2

试试这个

<div id="red">
  <div class="one"></div>
  <div class="two"></div>
  <div class="three"></div>
</div>
<div id="blue">
  <div class="sub one"></div>
  <div class="sub two"></div>
  <div class="sub three"></div>
</div>
   $('.one').click(function(){
        $('.sub').hasClass('one').show();
    });

Answer 3

<div id="red">
  <div class="one"></div>
  <div class="two"></div>
  <div class="three"></div>
</div>
<div id="blue">
  <div id="one" class="sub"></div>
  <div id="two" class="sub"></div>
  <div id="three" class="sub"></div>
</div>
$().ready(function(){
  $('.sub').hide();
  $('#red>div').click(function(){
    $('#' + $(this).attr('class')).show();
  });
});

Answer 4

试试这种方法，代码更少，工作更多：

jQuery:

$(function(){
  $('#red div').click(function(){//divs inside #red
    var takeClass = (this).attr('class');//takes clicked element's class
    //inside #blue div
    $('#blue .'+takeClass).show();//show's div which got clicked element's class
    // if clicked element's class is 'one', this will show '#blue .one'
  });
});

你的html:

<div id="red">
<div class="one"></div>
<div class="two"></div>
<div class="three"></div>
</div>
<div id="blue">
<div id="sub" class="one"></div>
<div id="sub" class="two"></div>
<div id="sub" class="three"></div>
</div>

我建议使用toggle而不是show，就像这样：

jQuery

$(document).ready(function() {
    $("#blue div").hide();
    $("#red div").click(function() {
        var redClass = $(this).attr("class");
        $("#blue ." + redClass).toggle();
    });
});

HTML结构：

<div id="red">
    <div class="one">1</div>
    <div class="two">2</div>
    <div class="three">3</div>
</div>
<div id="blue" class="sub">
    <div class="one">1</div>
    <div class="two">2</div>
    <div class="three">3</div>
</div>​
