集团企业网站建设文案,湖南营销型网站建设报价,wordpress圈子,Wordpress 数据10万先看效果 避免误会 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 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-cli…先看效果 避免误会 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

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 vkbeautifyexport 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

};
/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
templatediv!-- 引用插件 --VueDataEditorinputcodeChange:valuecode:disablefalse/VueDataEditorhr /el-button clickupdate typeprimary提交新代码块/el-button/div

};
/script启动项目即可实现最开始演示的效果
