Question

我正在最终确定我的网络应用程序，并开始测试不同浏览器的最新版本。

不幸的是，Internet Explorer（9）似乎有一些问题（再次！-.-），只有一行非常简单的代码。

我正在使用由amCharts lib设计的图表 - 并且已经实现了一个小函数来刷新它：

function validateData()
{
    chart.validateData();
    console.log("Data validated");      
}

现在，IE9不是仅执行amCharts函数＆＃34; validateData（）＆＃34;而是抛出错误：

SCRIPT5007: Unable to get value of the property "validateData": object is null or undefined

我发现这个错误特别令人不安，因为它说的是“获得价值”＃34;和＆＃34;财产＆＃34;。 validateData是一个函数（没有任何返回值）不是某些类型的属性，当然它没有价值...

IE试图在这做什么？！为什么它不像其他浏览器一样执行代码行......

我很感激你们能提供的任何帮助。

如果需要更详细的背景信息，我将在下面提供更多代码段：

});

// WRITE
chart.write("charts_container");

});

function zoomChart() {
    chart.zoomToIndexes(chartData.length - 40, chartData.length - 1);
}

function setPanSelect() {
if (document.getElementById("rb1").checked) {
    chartCursor.pan = false;
    chartCursor.zoomable = true;

} else {
    chartCursor.pan = true;
}
    chart.validateNow();

// Function that produces the error in IE9
function validateData()
{
    chart.validateData();
    console.log("Data validated");

修改

根据要求，这是一个调用validateData（）函数的片段。它位于HTML head

中的JS块中

// Before this is called there are several data transformation/manipulations 
// and other stuff regarding editing the source data from a XML file

if (filled == true)
{               
    for (k=0;k<arrDate.length;k++)
    {
        var dataObject = {
        date: arrDate[k],
        result: arrResult[k],
        };

        chartData.push(dataObject);

        validateData();
    }
}

与JavaScript结合使用IE9“SCRIPT5007：无法获取属性值”错误
