我正在使用 AngularJS 和 ui-codemirror 编写一个非常非常基本的 Playground 。这是代码 ( JSBin )。
<html>
<head>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.css">
<link rel="stylesheet" href="https://codemirror.net/lib/codemirror.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.min.js"></script>
<script src="https://codemirror.net/lib/codemirror.js"></script>
<script src="https://codemirror.net/addon/edit/matchbrackets.js"></script>
<script src="https://codemirror.net/mode/htmlmixed/htmlmixed.js"></script>
<script src="https://codemirror.net/mode/xml/xml.js"></script>
<script src="https://codemirror.net/mode/javascript/javascript.js"></script>
<script src="https://codemirror.net/mode/css/css.js"></script>
<script src="https://codemirror.net/mode/clike/clike.js"></script>
<script src="https://codemirror.net/mode/php/php.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.js"></script>
</head>
<body>
<div ng-app="myApp">
<div ng-controller="codeCtrl">
HTML:<br>
<textarea ui-codemirror ng-model="html"></textarea>
<br>CSS:<br>
<textarea ui-codemirror ng-model="css"></textarea>
</div>
Output:
<section id="output">
<iframe></iframe>
</section>
</div>
</body>
</html>
JavaScript:
var myApp = angular.module('myApp', ['ui']);
myApp.value('ui.config', {
codemirror: {
mode: 'text/x-php',
lineNumbers: true,
matchBrackets: true,
}
});
function codeCtrl($scope, codeService) {
$scope.html = '<body>default</body>';
$scope.css = "body {color: red}";
$scope.$watch('html', function () { codeService.render($scope.html, $scope.css); }, true);
$scope.$watch('css', function () { codeService.render($scope.html, $scope.css); }, true);
}
myApp.service('codeService', function () {
this.render = function (html, css) {
source = "<html><head><style>" + css + "</style></head>" + html +"</html>";
var iframe = document.querySelector('#output iframe'),
iframe_doc = iframe.contentDocument;
iframe_doc.open();
iframe_doc.write(source);
iframe_doc.close();
}
})
上面的代码有效，但问题是它将一个相同的 ui.config 应用于 2 个 ui-codemirror。有谁知道如何将模式 html 应用于第一个 ui-codemirror 并将模式 css 应用于第二个 ui-codemirror?
此外，如何设置 ui-codemirror 的高度(或 rows)和宽度(或 cols)？
最佳答案
Controller :
function codeCtrl($scope, codeService) {
$scope.editorOptions1 = {mode: 'text/html',
lineNumbers: false,
matchBrackets: true};
$scope.editorOptions2 = {mode: 'text/css',
lineNumbers: true,
matchBrackets: true};
$scope.html = '<body>default</body>';
$scope.css = "body {color: red}";
$scope.$watch('html', function () { codeService.render($scope.html, $scope.css); }, true);
$scope.$watch('css', function () { codeService.render($scope.html, $scope.css); }, true);
}
HTML :
<div ng-controller="codeCtrl">
HTML:<br>
<textarea ui-codemirror="editorOptions1" ng-model="html"></textarea>
<br>CSS:<br>
<textarea ui-codemirror="editorOptions2" ng-model="css"></textarea>
</div>
关于angularjs - 在 1 个 Controller 中使用 2 个 ui-codemirrors，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41498554/
