jQuery 遍历json数组的实现代码

使用JQuery 

<script type="text/javascript"> 
var json=[{"text":"王家湾","value":"9"},{"text":"李家湾","value":"10"},{"text":"邵家湾","value":"13"}];
$(json).each(function(){ 
alert(this.text+" "+this.value); 
}); 
</script> 

不用JQuery 

 function jsonstr(){

var json=[{"text":"王家湾","value":"9"},{"text":"李家湾","value":"10"},{"text":"邵家湾","value":"13"}];

var obj = eval（json);    

for (var i = 0; i < obj.length; i++) { 

alert(json[i].text+" " + json[i].value) 

}
