javascript

JS循环遍历JSON数据

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

用js可以写成：

1
2
3
4
5
6
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);  
}

或是

10
<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>
