Google图表不在Intellij上加载

问题描述

我试图用谷歌图表做一个饼图。当我把这个代码放到一个HTML文件，并在自己的正常工作运行。

这是什么样子：

但是，当我在Intellij的项目中运行它时，什么都没有出现。

下面是我的代码：

 < DIV> 
 
 <！ -  script type =text / javascriptsrc =views / jsapi.js>< / script  - > 
< script type =text / javascriptsrc =https://www.google.com/jsapi>< / script> 
 
< script type =text / javascript> 
 console.log（1）; 
 //加载Visualization API和饼图包。 
 google.load（'visualization'，'1.1'，{'packages'：['corechart']}）; 
 console.log（2）; 
 
 //设置回调以在加载Google Visualization API时运行。 
 google.setOnLoadCallback（drawChart）; 
 console.log（3）; 
 
 //创建并填充数据表的回调，
 //实例化饼图，传入数据并
 //绘制它。 
函数drawChart（）{
 console.log（4）; 
 
 //创建数据表。 
 var data = new google.visualization.DataTable（）; 
 data.addColumn（'string'，'Topping'）; 
 data.addColumn（'number'，'Slices'）; 
 data.addRows（[
 ['Mushrooms'，3]，
 ['Onions'，1]，
 ['Olives'，1]，
 [ '西葫芦'，1]，
 ['Pepperoni'，2] 
]）; 
 console.log（5）; 
 
 //设置图表选项
 var options = {'title'：'我昨晚吃了多少比萨'，
'width'：400，
'高度'：300}; 
 
 //实例化并绘制我们的图表，并传入一些选项。 
 var chart = new google.visualization.PieChart（document.getElementById（'chart_div'））; 
 chart.draw（data，options）; 
 console.log（6）; 
 
} 
 console.log（7）; 
 
< / script> 
 < div id =content> 
< div id =chart_div>< / div> 
< / div> 
< / div> 
  

为什么会发生这种情况？

解决方案

我通过修改这行代码来实现它：

  google.load（'可视化'，'1'，{packages：['corechart']}）; 
  

要这样：

  google.load（'visualization'，'1'，{packages：['corechart']，callback：drawChart}）;

I am trying to make a pie chart with Google Charts. When I put this code into an html file and run it on its own it works fine.

This is what it looks like:

However, when I run it within my project in Intellij nothing appears.

Here is my code:

<div>

        <!--Load the AJAX API-->
        <!--script type="text/javascript" src="views/jsapi.js"></script-->
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>

    <script type="text/javascript">
console.log("1");
    // Load the Visualization API and the piechart package.
    google.load('visualization', '1.1', {'packages':['corechart']});
console.log("2");

    // Set a callback to run when the Google Visualization API is loaded.
    google.setOnLoadCallback(drawChart);
console.log("3");

    // Callback that creates and populates a data table,
    // instantiates the pie chart, passes in the data and
    // draws it.
    function drawChart() {
        console.log("4");

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([
            ['Mushrooms', 3],
            ['Onions', 1],
            ['Olives', 1],
            ['Zucchini', 1],
            ['Pepperoni', 2]
        ]);
        console.log("5");

        // Set chart options
        var options = {'title':'How Much Pizza I Ate Last Night',
            'width':400,
            'height':300};

        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
        console.log("6");

    }
console.log("7");

</script>
    <!--Div that will hold the pie chart-->
    <div id="content">
        <div id="chart_div"></div>
    </div>
</div>

Why is this happening?

解决方案

I got it to work by modifying this line of code:

    google.load('visualization', '1', {packages: ['corechart']});

To this:

    google.load('visualization', '1', {packages: ['corechart'], callback : drawChart});
