从 textarea 轻弹到 ui-codemirror 框架

【中文标题】从 textarea 轻弹到 ui-codemirror 框架【英文标题】:Flick from a textarea to a ui-codemirror frame 【发布时间】:2017-07-03 22:43:33 【问题描述】:我想做一个文件编辑器。通过以下代码 (JSBin),我们在左侧列出了所有文件名,在右侧列出了它们的正文。我使用ui-codemirror
来设置文件主体的样式。
但是,当我们单击文件名并从一个文件名切换到另一个文件名时,有时会看到从文本区域快速滑动到代码镜像框架,这对于编辑器来说不是一个很好的体验.
有没有人有办法避免这个轻弹?另外,angularJS
和ui-codemirror
做编辑器是不是一个好方向?

【问题讨论】:
【参考方案1】:每次点击链接,都是新建编辑器,是开销操作。
The best approach is to create one editor and load the content on every click.
所以我删除了 ui-router 链接 (ui-sref) 和相关控制器
<script>
var app = angular.module('flapperNews', ['ui', 'ui.router']);
app.controller('MainCtrl', ['$scope', '$state', function ($scope, $state)
$scope.files = [
name: "index.html", body: "<html><body>index.html</body></html>" ,
name: "index.js", body: "the body of index.js" ,
name: "test.html", body: "the body of test.html" ];
$scope.editorOptionsHTML = mode: 'text/html', lineNumbers: true, matchBrackets: true ;
// for every click event it will load the content
$scope.go=function(file)
$scope.file=file;
]);
和身体
<body ng-controller="MainCtrl">
<div class="row">
<div class="col-sm-3 col-md-3 col-xl-3 col-lg-3">
<div ng-repeat="file in files track by $index">
<a ng-click="go(file)">file.name</a>
</div>
</div>
<div class="col-sm-9 col-md-9 col-xl-9 col-lg-9">
<textarea ui-codemirror="editorOptionsHTML" ng-model="file.body"></textarea>
</div>
</div>
</body>
例如:JSBin
【讨论】:
我不知道为什么你的 codepen 不工作...这是我的 JSBin 有同样的想法...【参考方案2】:您可以通过将hide
类添加到textarea
来避免轻弹,如以下代码(jsbin)
template: '<textarea class="hide" ui-codemirror="editorOptionsHTML" ng-model="file.body"></textarea>',
【讨论】:
感谢您的回答...现在好多了,我们再也看不到 从 textarea 到 ui-codemirror 的轻弹了。但是,当我们切换文件时(即使在具有相同内容的两个文件之间),我们仍然可以看到 不时的轻弹,我在 Chrome 和 Safari 中对其进行了测试。你有什么解决办法吗? 我意识到改变像here这样的外部链接解决了这个问题......以上是关于从 textarea 轻弹到 ui-codemirror 框架的主要内容,如果未能解决你的问题,请参考以下文章
