输出root的子对象数量 alert(dataObj.json.length);//输出json的子对象数量 //遍历json数组 $.each(dataObj.root, function(i, item) { alert(item.name+"-----root-------"+item.value); }); //遍历json数组 $.each(dataObj.json, function(i, item) { alert(item.name+"-----json-------"+item.value); }); }); //解析单个的json数组 $("#jsonArray2").click(function(){ var data=$(".jsonArray2").html(); alert("-----"+data); var dataObj=eval("("+data+")");//转换为json对象 alert(dataObj.length);//输出root的子对象数量 //遍历json数组 $.each(dataObj, function(i, item) { alert(item.name+"-----jsonArray-------"+item.value); }); }); ///解析标准的Json串 方法一 $("#jsonStr").click(function(){ var json=$(".jsonText").html(); alert("---2--"+json); var item = jQuery.parseJSON(json); alert(item.nickname); alert(item.ret); alert(item.figureurl ); }); ///解析标准的Json串，方法二 $("#jsonStr2").click(function(){ var json=$(".jsonText").html(); alert("---2--"+json); var obj = eval("("+json+")"); alert(obj.nickname); alert(obj.ret); alert(obj.figureurl ); });
