如何在Flask中使用jsonify返回两个数组? [英] How to return two arrays with jsonify in Flask?

问题描述

我试图返回代表图表值和标签的两个不同列表以进行jsonify，然后传递给Javascript函数以绘制图表，但它对我没有用.只有当我返回一个没有标签列表的值的列表时，它才起作用.

I'm trying to return two different lists that are representing a chart values and labels to jsonify then to be passed to Javascript function to draw the chart, but it never worked with me. It only worked when i returned a single list for values without the labels list.

以下是我的Flask脚本:

以下是我的包含jQuery和AJAX函数的Javascript代码:

    <script>

      var getValues = $.get('/data');
      getValues.done(function(values,labels){

      var data = {
        labels: [
          labels.labels
        ],

        series: [
          values.values
        ] };

        var options = {
          width : 800,
          height : 400
        }

        var myChart = new Chartist.Bar('.ct-chart', data, options);

      });

    </script>

推荐答案

您的/data端点返回可以在$.get参数中指定的JSON对象.

Your /data endpoint returns JSON object which you can specify in your $.get parameter.

$.get('/data', function(response){
    var data = {
        labels: response.labels,
        series: [response.values]
    };

    var options = {
      width : 800,
      height : 400
    }

    var myChart = new Chartist.Bar('.ct-chart', data, options);
}, "json");
