The method by which the JS loops through the JSON data

JS loops through JSON data

This article provides examples of JS loop JSON data columns, as well as JS loops traversing JSON data for learning.

1. Column loop of json data

var len = json.length;
for (var i = 0; i < len; i++)
{
for (obj in json[i])
{
var obj2 = obj;
}
}

2.JS loop through the JSON data

The method of traversing with the js loop is as follows:

//方法1，
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 ); 
      } 

//方法2，
<script type="text/javascript"> 
function text(){ 
  var json = {"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{/"text/":/"李家湾/",/"value/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}  
  json = eval(json.options) 
  for(var i=0; i<json.length; i++) 
  { 
     alert(json[i].text+" " + json[i].value) 
  } 
} 
</script>
