jquery implementation code for selecting all, not selecting all, and inverse selection effects [recommended]

First: introduce jquery

<title>haran.info_jquery实例_全选全不选反选_select-all_unselect-all_reverse</title>
<meta http-equiv="content-type"content="text/html; charset=UTF-8"/>
<script src="/js/jquery-1.8.3.min.js"type="text/javascript"></script><!-- 引入Jquery -->
 

Style:

<styletype="text/css">
<!--
#div1{
  width:980px;
  margin:0 auto;
  position:relative;
  text-align:left;
  padding-left:400px;
  line-height:30px;
  border:1px dotted #0075c5;
}
li{
  display:block;
  list-style:none;
  float:left;
  position:relative;
  padding-left:20px;
}
.clr{
  height:20px;
}
-->
</style>
 

body layout:

<divid="div1">
  <divclass="clr"> </div>

  <inputtype="checkbox"/><ahref="haran.info">haran.info_首页</a><br/>
  <!--选项结束-->
  <!--功能按钮开始-->
  <inputtype="button"id="selAll"value="全选"/> 
    
  <inputtype="button"id="unselAll"value="全不选"/> 
    
  <inputtype="button"id="reverse"value="反选 "/> 
  <!--功能按钮结束-->
  <divclass="clr"> </div>
</div><!--关闭div1-->

Function implementation:

<scripttype="text/javascript">
$(document).ready(function () {
      
  $("#selAll").click(function () { //":checked"匹配所有的复选
    $("#div1 :checkbox").attr("checked", true); //"#div1 :checked"之间必须有空格checked是设置选中状态。如果为true则是选中fo否则false为不选中
  });
      
  $("#unselAll").click(function () { 
    $("#div1 :checkbox").attr("checked", false); 
  });
      
  //理解用迭代原理each(function(){})
  $("#reverse").click(function () { 
  $("#div1 :checkbox").each(function () {
  $(this).attr("checked",!$(this).attr("checked")); //!$(this).attr("checked")判断复选框的状态：如果选中则取反
    }); 
  });
}); 
</script>

The above jquery implementation code for selecting all, selecting none, and inverting the selection effect [recommended] is all the content shared by the editor. I hope it can give you a reference, and I hope you will support Script Home.
