如题在JS中获取JSON中的数据
var newValue = {"1051431":"0","1051569":"0"};
var itemnum = arrValue[0];

alert(newValue.itemnum);

这样打印出undefined


------解决方案--------------------
var data = eval("("+newValue+")");//js 解析json数据,主要是因为json数据用单引号后变为字符串了

alert(data[itemnum]);

对于键名为数字或者非正常变量字符时（如有空格），必须使用obj[xx]方式获取值。
