Layui中引入Echarts模块实现图表显示

首先我们需要去Echarts官网下载Echarts图表源码，核心文件为这两个

 接着我们修改echarts.js代码

开头的修改为

(function (global, factory) {
	typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) :
	typeof define === 'function' && define.amd ? define(['exports'], factory) :
    window.layui && layui.define ? layui.define(function(exports){exports('echarts',factory(exports))}) :
	(factory((global.echarts = {})));
}

结尾加上一句话

return exports;

html

      
柱形图
        

            
 
        

js

我的echarts文件放在/resources/layui_ext/目录下的echarts/echarts.js，通过extend引入模块

 layui.config({base:'/resources/layui_ext/'}).extend({ dtree: 'dtree/dtree',echarts: 'echarts/echarts'}).use(['jquery', 'form', 'layer', 'laydate', 'table','layedit','upload', 'dtree','element', 'echarts', 'carousel'], function () {
        var $ = layui.jquery;
        var element = layui.element;
        carousel = layui.carousel;
        echarts = layui.echarts;
        var form = layui.form;
        var layer = layui.layer;
        var laydate = layui.laydate;
        var table = layui.table;
        var layedit = layui.layedit;
        var upload = layui.upload;
        var dtree = layui.dtree;

        var chartZhu = echarts.init(document.getElementById('EchartZhu'));
        //指定图表配置项和数据
        var optionchart = {
            title: {
                text: '商品订单'
            },
            tooltip: {},
            legend: {
                data: ['销量']
            },
            xAxis: {
                data: ['周一', '周二', '周三', '周四', '周五', '周六', '周天']
            },
            yAxis: {
                type: 'value'
            },
            series: [{
                name: '销量',
                type: 'bar', //柱状
                data: [100,200,300,400,500,600,700],
                itemStyle: {
                    normal: { //柱子颜色
                        color: 'red'
                    }
                },
            },{

                data:[120,210,340,430,550,680,720],

                        color:'blue'
                    }
                }
            }]
        };
