jQuery traverses objects, arrays, and collection instances_jquery

1.jquery traverse objects

Copy code The code is as follows:

2.jQuery traverses arrays

Copy code

The code is as follows:

 
 
  
   
   
   
     $(function(){ 
 
       var tbody = ""; 
     
     //------------遍历数组 .each的使用------------- 
           var anArray = ['one','two','three']; 
     $("#result").html("------------遍历数组 .each的使用-------------"); 
           $.each(anArray,function(n,value) { 
            
            alert(n ' ' value); 
           var trs = ""; 
             trs = "" value ""; 
              tbody = trs; 
            }); 
 
          $("#project").append(tbody); 
      
  }); 
   
  
  
  
    ------------此部分同1中的body部分-------------------- 
 
  

3.jQuery 遍历List集合（其实与遍历一个对象没有太大区别，只是格式上的问题） 

复制代码 代码如下:

 
 
 
  
   
   
   
     $(function(){ 
 
       var tbody = ""; 
     
     //------------遍历List集合 .each的使用------------- 
      var obj =[{"name":"项海军","password":"123456"},{"name":"科比","password":"333333"}]; 
    $("#result").html("遍历List集合 .each的使用"); 
      alert(obj);//是个object元素 
   //下面使用each进行遍历 
   $.each(obj,function(n,value) {  
           alert(n ' ' value); 
       var trs = ""; 
             trs = "" value.name " " value.password ""; 
             tbody = trs;        
           }); 
         $("#project").append(tbody); 
      
  }); 
   
  
  
  
       ------------此部分同1中的body部分--------------------
