Kaedah JS untuk mengulung melalui kemahiran JSON data_javascript

Data JSON seperti: {"options":"[{/"text/":/"Wangjiawan/",/"value/":/"9/"},{/"text/":/" Lijian/",/"nilai
e/":/"10/"},{/"text/":/"Shaojiawan/",/"value/":/"13/"}]"}

boleh ditulis dalam js sebagai:

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 ); 
}

atau

<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>
