Question

来自webservice的数据来自BindTrend方法，在绑定到图表之前将其解析为Json对象：我的代码如下：

 var plot;
    var itemdata = [];
    var chart;
    var data = [];
 $(document).ready(function () {

            $.ajax({
            type: "POST",
            url: "ChartBinder.asmx/BindTrend",
            data: "{}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {           
               var newJ = $.parseJSON(msg.d);               
                DrawTrend(newJ);
            },
            error: function (msg) {
                alert("Error");
            }
        });    
    })   

    function DrawTrend(plot) {
       for (i = 0; i < plot.length; i++) {
        var x = {}
        x.id=plot[i].Name;
        x.name = plot[i].Name;
        x.data = [plot[i].Value];
        itemdata.push(x);
        }
              chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'line',
                marginRight: 130,
                marginBottom: 25
            },
            series: itemdata
        });
    }

请注意，当我对值'x.data=[1,2,3....]'进行硬编码时，我可以获取图表。请帮助。

是因为你在'for'中声明x？

 var x = {}
 function DrawTrend(plot) {
       for (i = 0; i < plot.length; i++) {

        x.id=plot[i].Name;
        x.name = plot[i].Name;
        x.data = [plot[i].Value];
        itemdata.push(x);
        }
