javascript - 如何在 Highcharts 数据字段中设置变量

Question

数据来自后端，我可以在 java 脚本中使用警报查看数据。但无法在高位图(条形图)的数据部分动态设置数据。

var cwk = "${myFormpage.cweek}";
var cwk2 = "${myFormpage.cweek2}";
var cwk3 = "${myFormpage.cweek3}";

var series = [{
    name: 'This week',
    color: '#ed7717',
    data: [11000, 12000, 17000]
  }, {
    name: '4 week ago',
    color: '#bd0066',
    data: [11000, 12000, 17000]
  }, {
    name: '52 week back',
    color: '#691e7d',
    data: [10000, 11000, 14000]
  }
];

上面的代码片段工作正常。但是，如果我像动态添加数据一样

data: [cwk,cwk2,cwk3] 

图表未创建。请帮助我如何在没有 ajax 调用的情况下在此处添加动态数据。

根据我在您的代码中看到的内容，您似乎在此处将您的值转换为字符串:

var cwk = "${myFormpage.cweek}";
var cwk2 = "${myFormpage.cweek2}";
var cwk3 = "${myFormpage.cweek3}";

更改为:

var cwk = ${myFormpage.cweek};
var cwk2 = ${myFormpage.cweek2};
var cwk3 = ${myFormpage.cweek3};

它应该可以工作...
