vue-$nextTick及安装jq

一个页面中页面元素有图片、文字、外部文件链接，这些加载时候都会占据时间，js在做操作时，需要等所有元素都加载完进行操作，这个问题做项目时没有考虑到，导致在做dom操作时，获取页面高度，查找了很长时间的问题才解决。

这里使用了jq 操作dom 楼层滚动定位，添加一点安装步骤

1、npm install jquery --save-dev

2、build.js 中 webpack.base.dev.js 添加 var webpack = require('webpack')；

module.exports中添加新对象配置

plugins: [

new webpack.ProvidePlugin({

$: "jquery",

jQuery: "jquery"

})

]

3、mian.js 中   引入 import $ from 'jquery'
