jsonc

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能够写成：

[javascript] view
plaincopyprint?

1. var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}];
2. for(var o in data){
3. alert(o);
4. alert(data[o]);
5. alert("text:"+data[o].name+" value:"+data[o].age );
6. }

或是

[javascript] view
plaincopyprint?

1. <script type="text/javascript">
2. function text(){
3. var json = {"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{/"text/":/"李家湾/",/"value/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}
4. json = eval(json.options)
5. for(var i=0; i<json.length; i++)
6. {
7. alert(json[i].text+" " + json[i].value)
8. }
9. }
10. </script>
