vue入门

直接添加<el-upload发现点击不了，后来才知道，要加在<el-form-item></el-form-item>里面

1、<template></template>必须以<div>为根，不能两个<div>并列作为根【<template><div></div><div></div></template>】。

vue-router.esm.js?fe87:1981 Uncaught (in promise) TypeError: Cannot read property '__esModule' of undefined

原来写法

{
        path: '/add_operate',
        name: 'add_operate',
        component: resolve => require(['@/views/operate/add'])
    }

正确写法

{
        path: '/add_operate',
        name: 'add_operate',
        component: resolve => require(['@/views/operate/add'], resolve)
    }

修改日期控件，发现上面显示的日期并没有改变。

以前的错误写法

   this.ruleForm = {
        remark: this.addEditData.remark
      };
      if(this.addEditData.purcharsDate!=null && this.addEditData.purcharsDate>0){
          this.ruleForm["purcharsDate"] = this.$dateFormat(this.addEditData.purcharsDate, "yyyy/MM/dd")
      }//后插入

现在正确的写法：

 var purcharsDate = '';
      //alert(this.addEditData.purcharsDate);
      if(this.addEditData.purcharsDate!=null && this.addEditData.purcharsDate>0){
          purcharsDate = this.$dateFormat(this.addEditData.purcharsDate, "yyyy/MM/dd")
      }
      this.ruleForm = {
        remark: this.addEditData.remark,
        purcharsDate: purcharsDate
      };//前插入

这个报错是nodejs版本太低了，下载一个最新的就好了。

因为我的系统是win7的，支持的最高版本是v13.14.0

nodejs再高版本就要win8.1及以上了：

This application is only supported on Windows 8.1, Windows Server 2012 R2, or higher.
