：使用jQuery的jsonp时回调函数间歇出现异常"缺少对象"
请求帮助：使用jQuery的jsonp时回调函数间歇出现错误"缺少对象"。
从远程服务器请求数据在网站上绘制flot曲线图，使用jsonp调用，代码是参考网上的示例，调用返回数据每次看都没有问题，但是经常出现缺少对象错误，然后flot图当然绘不出来了，刷新后有时可以成功有时失败。
请高人帮我看看怎样解决这个问题。
错误提示如下：
调试信息如下，当鼠标放在上面会显示"onDataReceived undefined"，返回数据是正常的：
错误后显示图形是空白的：
刷新后大多数可以正常显示：
我的js调用代码如下：
显示html页面代码如下：
服务器返回数据如下：
------解决思路----------------------
function onDataReceived(series) {
//alert(series);
data.push(series);
$.plot("#loadchart", data, options);
}
放到window对象下
或者window.onDataReceived=function(series) {
//alert(series);
data.push(series);
$.plot("#loadchart", data, options);
}
