Question

我想打印一些名为sqlOutput的div的动态文本。我想用换行符来格式化它。我试过了（显然是<br>和/\r\n）。但它没有用。

如何使用Angular创建格式正确的文本？

$scope.buildScripts = function () {
    var mainTable = "DROP TABLE [dbo].[" + $scope.tableName + "] <br>"
        + "GO <br>"
        + "SET ANSI_NULLS ON <br>"
        + "GO <br>"
        + "SET QUOTED_IDENTIFIER ON <br>"
        + "GO <br>"
        + "SET ANSI_PADDING ON <br>"
        + "GO <br>"
        + "CREATE TABLE [dbo].[" + $scope.tableName + "](";

    $scope.sqlOutput = mainTable;
}

如果要在视图中显示变量中的一些html代码，则必须创建过滤器。此过滤器将授权解释的HTML代码。默认情况下，此功能已禁用以防止出现安全问题。（更多阅读her和her）

1）创建一个过滤器：

// Declare the main module
var myApp = angular.module('myApp', []);

angular.module('myApp').filter('unsafe', function ($sce) {
   return function (val) {
      if( (typeof val == 'string' || val instanceof String) ) {
         return $sce.trustAsHtml(val);
      }
   };
});


myApp.controller('Ctrl1', ['$scope',  function($scope) {
    $scope.tableName = "userXXX" ;
    $scope.buildScripts = function () {
        var mainTable = "DROP TABLE [dbo].[" + $scope.tableName + "] <br>"
            + "GO <br>"
            + "SET ANSI_NULLS ON <br>"
            + "GO <br>"
            + "SET QUOTED_IDENTIFIER ON <br>"
            + "GO <br>"
            + "SET ANSI_PADDING ON <br>"
            + "GO <br>"
            + "CREATE TABLE [dbo].[" + $scope.tableName + "](";

        $scope.sqlOutput = mainTable;
    } 
    $scope.buildScripts();
}]);

2）在视图中使用过滤器：

<span ng-bind-html="sqlOutput  | unsafe "></span>
