这是一个在线编辑器我们可以在这上面随意的编写xml代码格式

我们修改上面的内容之后就可以在控制台输出内容

在这里插入图片描述
如果这正是您想要的东西那就可以先创建一个vue项目

我们先引入依赖

npm install brace -S
npm install element-ui  -S
npm install vue-clipboard2 -S
npm install vkbeautify --save

然后在src 目录下新建文件夹就叫 components
在components下再创建一个文件叫 editor

然后在下面创建一个js文件叫 data_format_utils

data_format_utils.js 参考代码如下


// 对json和xml进行格式化
import vkbeautify from 'vkbeautify'export function string_to_json_wrap(v) {try {if (is_json(v)) {return unicode_to_china(JSON.stringify(string_to_json(v), null, '\t'))} else {return v}} catch (e) {console.log(e);}return v
}export function json_wrap_to_string(v) {try {if (is_json(v)) {return unicode_to_china(JSON.stringify(string_to_json(v)))} else {return v}} catch (e) {console.log(e);}return v
}export function string_to_xml_wrap(v) {try {return vkbeautify.xml(v);} catch (e) {return v}
}export function xml_wrap_to_string(v) {try {return vkbeautify.xmlmin(v);} catch (e) {return v}
}export function is_json(str) {if (typeof str == 'string') {try {let obj = JSON.parse(str);if (typeof obj == 'object' && obj) {return true;} else {return false;}} catch (e) {return false;}}
}export function check_string_type(v) {try {if (v.startsWith("<!DOCTYPE html")) {return 'HTML'} else if (v.startsWith("<")) {return 'XML'} else if (is_json(v)) {return 'JSON'} else {return 'TEXT'}} catch (e) {return 'TEXT'}
}export function wrap_to_string(v, t) {let type = t || check_string_type(v)switch (type) {case 'JSON': {return json_wrap_to_string(v)}case 'XML': {return xml_wrap_to_string(v)}case 'HTML': {return xml_wrap_to_string(v)}}return v
}export function string_to_wrap(v, t) {let type = t || check_string_type(v)switch (type) {case 'JSON': {return string_to_json_wrap(v)}case 'XML': {return string_to_xml_wrap(v)}case 'HTML': {return string_to_xml_wrap(v)}}return v
}export function string_to_json(v) {try {if (is_json(v)) {return v} else {return v}} catch (e) {return v}
}export function unicode_to_china(input) {try {return input.replace(/\\\\u([0-9a-fA-F]{2,4})/g, function (string, matched) {return String.fromCharCode(parseInt(matched, 16))})} catch (e) {console.log(e);}return input
}

然后在 editor目录下创建一个组件我这里叫 index.vue

参考代码如下

<template><div><el-card class="box-card"><!-- 操作栏 --><el-row slot="header" class="clearfix" v-if="toolbar == true"><el-col :span="5"><el-button type="primary" @click="toolsBarLeft">格式化</el-button><el-button type="primary" @click="toolsBarRight">恢复</el-button></el-col><el-col :span="6"><el-select v-model="value_type"><el-option label="JSON" value="JSON"></el-option><el-option label="TEXT" value="TEXT"></el-option><el-option label="XML" value="XML"></el-option><el-option label="HTML" value="HTML"></el-option></el-select></el-col><el-col :span="2" style="float:right"><el-button type="primary" v-clipboard:copy="contentBackup" @click="copy_value">复制</el-button></el-col></el-row><!-- 编辑器 --><div ref="vue_editor" style="height: 50vh;width: 100%"></div></el-card></div>
</template>
<style>
.box-card {margin: 20px;
}
.btn-hover {padding-left: 6px;padding-right: 6px;
}
.btn-hover:hover {background: #e0e0e0 !important;
}
.ace-xcode .ace_gutter {border-right: none !important;background: #fafafa !important;
}
.ace_content_disable {background: #fafafa !important;
}
</style>
<script>
// 引入ace代码编辑器
import ace from "brace/index";
import "brace/ext/emmet";
import "brace/ext/language_tools";
import "brace/mode/html";
import "brace/mode/json";
import "brace/mode/text";
import "brace/mode/xml";
import "brace/mode/javascript";
import "brace/theme/xcode";
import "brace/theme/terminal";
import "brace/snippets/javascript";
// 代码格式化方法
import {string_to_json_wrap,json_wrap_to_string,string_to_xml_wrap,check_string_type,wrap_to_string,string_to_wrap
} from "./data_format_utils";
// 主要代码
export default {name: "vue_editor",/*** 参数介绍：* value：（必填）双向绑定的数据；* theme：（非必填）ace编辑器主题默认xcode，可根据官网自行更换；* height：（必填）高度；* width：（必填）宽度；* options：（非必填）ace编辑器的设置* toolbar: （非必填）操作栏；* disable：（必填）是否启用编辑功能；* type：（非必填）json/xml/html/text，也支持更多，自行引用**/props: {value: {required: true},theme: {type: String,default: "xcode",required: false},options: Object,toolbar: {required: false,default: true,type: Boolean},disable: {required: false,type: Boolean,default: false},type: {required: false,type: String}},data() {return {editor: null,contentBackup: "",value_type: null,internalChange: false};},watch: {theme(v) {this.editor.setTheme("ace/theme/" + v);},options(v) {this.editor.setOptions(v);},height() {this.$nextTick(function() {this.editor.resize();});},width() {this.$nextTick(function() {this.editor.resize();});},value(v) {if (this.editor && !this.internalChange) {v = v && v !== null ? v : "";typeof v === "object" && (v = JSON.stringify(v));this.contentBackup = string_to_wrap(v);this.value_type = this.type || check_string_type(this.contentBackup);this.editor.session.setValue(this.contentBackup);}},value_type(nv) {switch (nv) {case "JSON": {this.contentBackup = string_to_json_wrap(this.contentBackup);this.editor.getSession().setMode("ace/mode/" + nv.toLowerCase());this.editor.session.setValue(this.contentBackup);break;}case "TEXT": {this.contentBackup = json_wrap_to_string(this.contentBackup);this.editor.getSession().setMode("ace/mode/" + nv.toLowerCase());this.editor.session.setValue(this.contentBackup);break;}case "XML": {this.contentBackup = string_to_xml_wrap(this.contentBackup);this.editor.getSession().setMode("ace/mode/" + nv.toLowerCase());this.editor.session.setValue(this.contentBackup);break;}case "HTML": {this.contentBackup = string_to_xml_wrap(this.contentBackup);this.editor.getSession().setMode("ace/mode/" + nv.toLowerCase());this.editor.session.setValue(this.contentBackup);break;}// 新增类别case "javascript": {this.editor.getSession().setMode("ace/mode/" + nv.toLowerCase());this.editor.session.setValue(this.contentBackup);break;}}},disable(v) {if (this.editor) {this.editor.setReadOnly(v);v? this.$refs.vue_editor.classList.add("ace_content_disable"): this.$refs.vue_editor.classList.remove("ace_content_disable");}}},methods: {// 单位校验px(n) {if (/^\d*$/.test(n)) {return n + "px";}return n;},// 格式化toolsBarLeft() {this.contentBackup = string_to_wrap(this.contentBackup, this.value_type);this.editor.session.setValue(this.contentBackup);},// 数据转字符串toolsBarRight() {this.contentBackup = wrap_to_string(this.contentBackup, this.value_type);this.editor.session.setValue(this.contentBackup);},copy_value() {this.$copyText(this.contentBackup).then(() => {this.$message.success("已经复制到粘贴板！");},() => {this.$message.error("复制失败！");});},onChange() {let error = false;let v;try {v = this.editor.getValue();error = false;} catch (err) {error = true;}if (error) {this.$emit("error");} else {if (this.editor) {this.internalChange = true;this.contentBackup = v;this.$emit("input", v);this.$nextTick(() => {this.internalChange = false;});}}},// 编辑器initView() {this.contentBackup = this.value && this.value !== null ? this.value : "";this.value_type = check_string_type(this.value);let vm = this;let lang = this.lang || "text";let theme = this.theme && this.theme !== "xcode" ? this.theme : "xcode";let editor_div = this.$refs.vue_editor;let editor = (vm.editor = ace.edit(editor_div));this.$emit("init", editor);editor.$blockScrolling = Infinity;editor.setOption("enableEmmet", false);editor.getSession().setMode("ace/mode/" + lang);editor.setTheme("ace/theme/" + theme);editor.getSession().setUseWrapMode(true);editor.setShowPrintMargin(false);editor.setValue(this.contentBackup);editor.on("change", vm.onChange);if (vm.options) editor.setOptions(vm.options);if (vm.disable) {editor.setReadOnly(true);}// 启用提示editor.setOption({enableBasicAutocompletion: true,enableSnippets: true,enableLiveAutocompletion: true});}},beforeDestroy() {this.editor.destroy();this.editor.container.remove();},mounted() {this.initView();}
};
</script>

然后在 src下的 main.js全局引入依赖参考代码如下


import Vue from 'vue'
import App from './App.vue'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.config.productionTip = false
Vue.use(ElementUI);// 引入复制
import VueClipboard from 'vue-clipboard2'
VueClipboard.config.autoSetContainer = true
Vue.use(VueClipboard)new Vue({render: h => h(App),
}).$mount('#app')

然后因为这是个实验的项目我就直接将最终引入的代码写在App.vue里啦

在src项目下找到根节点 App.vue组件
参考代码如下
