vue-devtools 是一款开发vue 应用时不可或缺的超好用的插件，且它提供了多个浏览器的支持！chrome 的应用市场可以直接搜索下载安装，但是您要是打不开应用市场（你能正常的打开算我输）可以使用如下的方法

短信验证 现在是市面上比较流行的一种验证方式，最近公司的项目有涉及到故整体如下

sendMsm: function(wait, objectb) {

	var time = wait;

	if(time == 0) {

		$(objectb).removeAttr("disabled");

		$(objectb).text("获取验证码");

		$(objectb).removeClass('hidden');

		$(objectb).next().addClass('hidden');

		time = wait;

	} else {

		$(objectb).attr("disabled", true);

		$(objectb).addClass('hidden');

		$(objectb).next().removeClass('hidden').text(time + " s 后重发");

		time--;

		setTimeout(function() {

			qdcms.sendMsm(time, objectb);

		}, 1000)

	}

}

<a class="btn btn-black" onclick="qdcms.getcode(60,this)">获取验证码</a>

<span class="btn btn-black disabled hidden"></span>

<template>

	<button class="timerout" :disabled="disabled || time > 0" @click='run'>

        {{ text }}

    </button>

</template>

<script>

	export default {

			run() {

				this.time = this.second;

				this.timer();

			},

			timer() {

				if(this.time > 0) {

					this.time--;

					setTimeout(this.timer, 1000);

				}

			}

		},

		computed: {

			text() {

				return this.time > 0 ? this.time + 's 后重新获取' : '点击获取验证码';

			}

		},

		mounted: function() {

vue 和 bootstrap 作为前端中 js 和css 框架中的佼佼者 二者结合肯定能蹦出不一样的火花！！

var webpack=require('webpack');

plugins: [ 

 new webpack.ProvidePlugin({ 

  $:"jquery", 

  jQuery:"jquery", 

  "windows.jQuery":"jquery"

 }) 

]

（其实这里你应该拒绝的 但是不排除一下吧下改变不了习惯的 ）

import $ from 'jquery'

alias: { 

   'vue$': 'vue/dist/vue.esm.js', 

   '@': resolve('src'), 

   'assets': path.resolve(__dirname, '../src/assets'), 

   'jquery': "jquery/src/jquery"

  } 

import './assets/css/bootstrap.min.css'

import './assets/js/bootstrap.min'

surePay() {

	this.showcontent = true;

	let newTab=window.open('about:blank');

	api.pay(this.refsend.type,this.refsend.money).then(response => {

		if(response.success&&response.data) {

			 newTab.location.href = 'http://'+response.data

		} else {

			window.alert("非法操作");

		}

	});

}
