Django的一点小知识

1. 静态文件的建立，可以在app01项目下新建一个static文件夹存放静态文件

 2. 在html中首行添加命令导入静态文件，静态文件导入如下

{% load static %}

 3. js里面画图

function int（）{ } 里面是一个完整的图的代码，代码来源于echarts

$(function () {


    init();

})

function init() {

    var colors = ['#FF6347','#228B22']
    var histogramChart1 = echarts.init(document.getElementById('histogramChart1'));
    histogramChart1.setOption({
        legend: {
            left: 30,
            top: 5,
            textStyle: {color: '#C0C0C0'},
        },
        toolbox: {
            feature: {
                saveAsImage: {
                    title: '下载',
                    backgroundColor: "RGB(8, 24, 50, 1)",
                }
            },
             iconStyle: {
                borderColor: "rgba(248, 245, 245, 1)"
            },
            },
        tooltip: {
            trigger: 'item',
            formatter: function (params) {
              return `${params.data.name} 
时长:${params.data.value}s`
            }
          },

        series: [
            {
                name: 'Nightingale Chart',
                type: 'pie',
                radius: [15, 90],
                center: ['50%', '60%'],
                roseType: 'area',
                itemStyle: {
                    borderRadius: 8
                },
               
                 data: [
                     {value: 511, name: 'rose 1'},
                     {value: 0, name: 'rose 2'},
                     {value: 224, name: 'rose 3'},
                     {value: 30, name: 'rose 4'},
                     {value: 28, name: 'rose 5'},
                     {value: 26, name: 'rose 6'},
                     {value: 22, name: 'rose 7'},
                     {value: 18, name: 'rose 8'}
                 ]
            }
        ]

    })
