vue项目中仿element-ui弹框效果的实例代码

最近要写个弹框，发现element-ui弹框样式还可以，就copy下来改吧改吧。也不分步骤详细介绍了直接上代码。

在组件目录中新建文件夹message

我把message目录里的东西给大家贴出来

message文件夹

src文件夹

index.js

import message from './src/main.js';
export default message;

mian.js

import vue from 'vue';
import main from './main.vue';
let messageconstructor = vue.extend(main);
let instance;
let instances = [];
let seed = 1;
const message = (options = {}) => {
 if (typeof options === 'string') {
 options = {
  message: options
 };
 }
 let useronclose = options.onclose;
 let id = 'message_' + seed++;
 options.onclose = function() {
 message.close(id, useronclose);
 };
 instance = new messageconstructor({
 data: options
 });
 instance.id = id;
 instance.vm = instance.$mount();
 document.body.appendchild(instance.vm.$el);
 instance.vm.visible = true;
 instance.dom = instance.vm.$el;
 instance.dom.style.zindex = 999;
 instances.push(instance);
 return instance.vm;
}
['success', 'warning', 'info', 'error'].foreach(type => {
 message[type] = options => {
 if (typeof options === 'string') {
  options = {
  message: options
  };
 }
 options.type = type;
 return message(options);
 };
});
message.close = function(id, useronclose) {
 for (let i = 0, len = instances.length; i < len; i++) {
 if (id === instances[i].id) {
  if (typeof useronclose === 'function') {
  useronclose(instances[i]);
  }
  instances.splice(i, 1);
  break;
 }
 }
};
message.closeall = function() {
 for (let i = instances.length - 1; i >= 0; i--) {
 instances[i].close();
 }
};

export default message;

mian.vue

<template>
 <transition name="message-fade">
  <div :class="[
   'message',
   type && !iconclass ? `message-${ type }` : '',

 const typemap = {

  typeclass() {

   ? `message-icon icon-${ typemap[this.type] }`

  }

  closed(newval) {
  if (newval) {
   this.visible = false;
   this.$el.addeventlistener('transitionend', this.destroyelement);

  destroyelement() {
  this.$el.removeeventlistener('transitionend', this.destroyelement);
  this.$destroy(true);
  this.$el.parentnode.removechild(this.$el);
  },
  close() {
  this.closed = true;
  if (typeof this.onclose === 'function') {
   this.onclose(this);
  }
  },
  cleartimer() {
  cleartimeout(this.timer);
  },
  starttimer() {
  if (this.duration > 0) {
   this.timer = settimeout(() => {
   if (!this.closed) {
    this.close();
   }
   }, this.duration);
  }
  },
  keydown(e) {
  if (e.keycode === 27) { // esc关闭消息
   if (!this.closed) {
   this.close();
   }
  }
  }
 },
 mounted() {
  this.starttimer();
  document.addeventlistener('keydown', this.keydown);
 },
 beforedestroy() {
  document.removeeventlistener('keydown', this.keydown);

 }
</script>
<style lang="less">

  }
 }
 .message-fade-enter,
 .message-fade-leave-active {
  opacity: 0;
  transform: translate(-50%, -100%);
 }
</style>

以上就是封装的所有代码
 接下来就来看看如何引用

main.js中引入

import message from '@/components/message/index.js'

vue.prototype.$message = message

调用

在你需要的页面调用

this.$message({
  message: '提示消息',
  type:'error' //type有四个值 1.error 2.success 3.info 4.warning
});

type为success

type为warning

type为info

type为errpr

小icon的图片用自己的图片哦
