• [javascript] 基于elementui的后台界面开发

    elementui是一套vuejs框架的ui库 , 主要逻辑是按照vuejs的组件方式来组合的

    安装有多种方式,可以使用npm的包安装,也可以直接引用cdn资源,在这里为了简单起见使用cdn方式. 主体架构还是传统的iframe的结构 , 框进来一个main界面

    没有使用vue-router , 只是把vue当做一个模板引擎来用

    引入资源还是这种直接引入 , 没有使用构建工具去打包 , 因为对于后端来说 ,还是这种方式最简单直观有效

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/element-ui@2.13.1/lib/theme-chalk/index.css">
        <script src="https://cdn.jsdelivr.net/npm/jquery/dist/jquery.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
    <!-- 引入组件库 -->
    <script src="https://cdn.jsdelivr.net/npm/element-ui@2.13.1/lib/index.js"></script>

    把结构加上 , 架构使用template包起来 ,这样在js渲染之前不会显示出乱的界面 . 标签上的属性传参和循环逻辑等都是vuejs里面的功能 , 需要看vuejs的文档才能知道这些是干啥的

    <div id="app">

    js把数据 , 绑定的点击事件等加上

        <script>
        new Vue({
            el: '#app',
            data: function () {
                return {

            },
            methods: {
                openUrl: function (url,msg) {
                    this.iframeUrl=url;
                }
            }
        })


    </script>
