完全照搬不一定能写出来 只是让看个思想
<template>

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"
},

vue组件中代码直接贴出来，废话不多说：
<template>
<div class="chatIcon">
<el-popover
placement="top-start"
width="400"
trigger="click"
class="emoBox"
>
<div class="emotionList">
<a
href="javascript:void(0);" rel="external nofollow"
@click="getEmo(index)"
v-for="(item, index) in faceList"
:key="index"
class="emotionItem"
>{{ item }}</a
>
</div>
<el-button
class="emotionSelect"
icon="iconfont icon-biaoqing"
slot="reference"
></el-button>
</el-popover>
<el-input
v-model="textarea"
class="chatText"
resize="none"
type="textarea"
id="textarea"
rows="5"
@keyup.enter.native="sendInfo"
></el-input>
</div>
</template>
<script>
const appData = require("@/utils/emoji.json");
export default {
mounted() {
for (let i in appData) {
this.faceList.push(appData[i].char);
}
},
data() {
return {
faceList: [],
textarea: ""
};
},
methods: {
getEmo(index) {
var textArea = document.getElementById("textarea");
function changeSelectedText(obj, str) {
if (window.getSelection) {
// 非IE浏览器
textArea.setRangeText(str);
// 在未选中文本的情况下，重新设置光标位置
textArea.selectionStart += str.length;
textArea.focus();
} else if (document.selection) {
// IE浏览器
obj.focus();
var sel = document.selection.createRange();
sel.text = str;
}
}
changeSelectedText(textArea, this.faceList[index]);
this.textarea = textArea.value; // 要同步data中的数据
// console.log(this.faceList[index]);
return;
}
}
};
</script>
<style lang="scss">
/* el-popover是和app同级的，所以scoped的局部属性设置了无效 */
/* 需要设置全局style */

</style>
