Javascript Internet Explorer指给我一条被注释掉的线并说它'；这是个错误

IE把我指给我看

this.DboChart = this.GetDboChart(); // "Deals By Offer" chart
    //this.PpvdbaChart = this.GetPpvdbaChart(); // "% Pipeline Value of Deals By Area"
    this.Mdcc = this.GetMdccChart(); // "MSfC Deals - Cumulative Count"

说

对象不支持属性或方法“GetPpvdbaChart”

毫无意义。假设它没有被注释掉，我仍然不知道它是从哪里得到这个简单有效的函数的

Calculator.prototype.GetPpvdbaChart = function ( )
{
    var areaData = new Array();     
    var calc = this;            
    this.Data.forEach(function(reg, idx){
        areaData.push({ value     : reg.NumOpportunities, 
                        color     : calc.ColorStack[idx % calc.ColorStack.length],
                        highlight : calc.HighlightColor, 
                        label     : reg.RegionName });  
    });
    return new Chart(document.getElementById("pipeline-deals-by-area").getContext("2d")).Pie(calc.areaData,calc.AreaOptions);       
}

不受支持。

确定吗？你能把屏幕贴出来吗？它是在评论的地方还是在定义的地方显示错误？
