完全照搬不一定能写出来 只是让看个思想
<template>
<section class="dialogue-section clearfix" >
<div class="row clearfix" v-for="(item,index) in msgs" :key = index>
<img :src="item.uid == myInfo.uid ? myInfo.avatar :otherInfo.avatar" :class="item.uid == myInfo.uid ? 'headerleft' : 'headerright'">
<p :class="item.uid == myInfo.uid ? 'textleft' : 'textright'" v-html="customEmoji(item.content)"></p>
</div>
</section>
<div id="emoji-list" class="flex-column" v-if="emojiShow"> //首先根据这个来判断发送表情弹窗用不用出现
<div class="flex-cell flex-row" v-for="list in imgs">
<div class="flex-cell flex-row cell" v-for="item in list" @click="inputEmoji(item)">
<img :src="'./emoji/'+ item + '.png'">
</div>
</div>
</div>
</template>
<script>
import { sendMsg } from "@/ws"; //是一个长连接
import _ from "lodash";//这个是js一个很强大的库
import eventBus from '@/eventBus'//这是一个子父传递的公共文件
console.log(emoji)
export default {
data() {
this.imgs = _.chunk(emoji, 6) //这个是调用lodash库的chunk方法 把 六个元素分成一个数组只不过是emoji这个数组中的二维数组
return {
emojiShow: false //刚开始默认不显示 点击按钮显示 点击的按钮上可以写@click='emojiShow=emojiShow'这种写法
};
},
methods: {
customEmoji(text) { //这个函数就是服务器端把传过来的名称转化为图片的
return text.replace(/\[([A-Za-z0-9_]+)\]/g, '<img src="./emoji/$1.png" style="width:30px; height:30px;">')
},
inputEmoji(pic) {
this.content += `[${pic}]`//传过来的名字转为图片
}
};
</script>
<style scoped>
@import '../../assets/css/dialogue.css';
#emoji-list {
height: 230px;
background: #fff;
}
#emoji-list .cell {
line-height: 13vh;
border-right: 1rpx solid #ddd;
border-bottom: 1rpx solid #ddd;
}
.flex-row {
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
}
.flex-column {
display: flex;
flex-direction: column;
justify-content: center;
align-items: stretch;
}
.flex-cell {
flex: 1;
}
.cell img {
width: 35px;
height: 35px;
}
</style>
补充知识：vue+element-ui实现聊天表情包
我是用的本地json数据实现的，表情不是很多，首先创建个json文件，代码如下：
[{
"codes": "1F600",
"char": "😀",
"name": "grinning face"
},
{
"codes": "1F603",
"char": "😃",
"name": "grinning face with big eyes"
},
{
"codes": "1F604",
"char": "😄",
"name": "grinning face with smiling eyes"
},
{

},
{

},
{

vue组件中代码直接贴出来，废话不多说：

const appData = require("@/utils/emoji.json");
export default {

},
methods: {

function changeSelectedText(obj, str) {
if (window.getSelection) {

textArea.selectionStart += str.length;
textArea.focus();

}
