JS循环遍历JSON数据的方法

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 ); }

<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>
