回传json时的遍历

 

JSON数据如：{"options":"[{\"text\":\"王家湾\",\"value\":\"9\"},{\"text\":\"李家湾\",\"valu
e\":\"10\"},{\"text\":\"邵家湾\",\"value\":\"13\"}]"}

用js可以写成： JSON数据如：{"options":"[{\"text\":\"王家湾\",\"value\":\"9\"},{\"text\":\"李家湾\",\"valu
e\":\"10\"},{\"text\":\"邵家湾\",\"value\":\"13\"}]"}

用js可以写成：

view plaincopy to clipboardprint?
01.var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}];  
02.      for(var o in data){  
03.        alert(o);  
04.        alert(data[o]);  
05.        alert("text:"+data[o].name+" value:"+data[o].age );  
06.      } 
var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}];
   for(var o in data){
    alert(o);
  alert(data[o]);
    alert("text:"+data[o].name+" value:"+data[o].age );
   }
