$ compile只是将文本编译为html。
这是示例示例
angular .module("myModule", []) .controller("myController", ['$scope', '$compile', function ($scope, $compile) { $scope.txt = "<b>SampleTxt</b>"; $scope.submit = function () { var html = $compile($scope.txt)($scope); angular.element(document.getElementById("display")).append(html); } }]);<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><body ng-app="myModule" > <div ng-controller="myController"> <textarea ng-model="txt" ></textarea> <input type="button" value="submit" ng-click="submit()" /> <div id="display"></div> </div></body>
