问题 I am new to selenium and trying to input text into a textarea generated by CodeMirror. I have looked at the other questions on textarea and am unable to solve my problem.

Debouncing CodeMirror Input on change event

阅读更多关于 Debouncing CodeMirror Input on change event

问题 I have a very simple implementation of EasyMDE, which internally uses CodeMirror. So to check for change of input I need to do this as said in the EasyMDE docs. Which works fine and I can even detect for change and get the input value as well. The problem right now I facing is that, there is no debounce available in both EasyMDE/CodeMirror and I am syncing the input on change to my backend functionality. On every input event I cant afford to sync to backend as it is may become very expensive.

vue（element）中使用codemirror实现代码高亮，代码补全，版本差异对比使用的是vue语言，用element的组件，要做一个在线编辑代码，要求输入代码内容，可以进行高亮展示，可以切换各不同语言，而且支持关键字补全，还要有一个各不同版本间的代码左右比较，这就是需求。至于为什么选中codemirror，请查看 vue（element）中代码高亮插件全面对比好了，现在正式开工吧！首先需要下载codemirror组件，diff-match-patch组件 npm install codemirror npm install diff-match-patch 当然啦，npm下载很是缓慢，换个国内镜像，淘宝的吧。果然，速度就嗖嗖的起来。 npm install -g cnpm --registry=https://registry.npm.taobao.org cnpm install cnpm install codemirror cnpm install diff-match-patch 可在node_modules下看到其目录结构核心代码如下，简练易懂，可以根据下面的自己在接着定制开发。 <template> <div>  <el-button @click="handleAdd">代码编辑，高亮补全</el-button> <el

【推荐阅读】微服务还能火多久？>>> Error in v-on handler: "TypeError: Cannot read property 'value' of undefined" 报错如下所示，即在运行Vue项目时出现了上述错误，出现该错误的原因是其容器还未生成就对其进行了初始化所造成的。首先检查有没有如下操作 //原先取dom的操作 document.getElementById('textarea'); //改正后，Vue中取demo的操作 this.$refs.textarea 如果问题还没有解决，就是$refs依旧获取不到值，即取不到el-dialog对话框中的子组件对象，返回的都是undefined。在其外面加上如下所示， this.$nextTick(function () { }); 比如我的 this._initialize() 方法里面获取不到 this.$refs.textarea 的值，一直为undefined，我就在其外面加上了 this.$nextTick(function () { this._initialize(); }); 如果问题还没有解决，你就要先打开el-dialog，让弹出框被初始化，只有el-dialog被初始化了，在Vue的渲染引擎中，你才可以获取到里面的子组件。如下，我要做的是打开一个弹框
