AngularJS中的javascript换行符

[英]javascript newline character in AngularJS

I want to print out some dynamic text to my div called sqlOutput. 我想打印一些动态文本到我的div中,称为sqlOutput。 I want it to be formatted with newline characters. 我希望它使用换行符格式化。 I've tried (obviously <br> and /\\r\\n ). 我已经尝试过(显然<br>/\\r\\n )。 But it didn't work. 但这没有用。

How can I have a well formatted text using Angular? 如何使用Angular获得格式正确的文本?

$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;
}

If you want to display in the view some html code from a variable you have to create a filter. 如果要在视图中显示某个变量的一些html代码,则必须创建一个过滤器。 this filter will authorise interpreted html code. 此过滤器将授权解释的html代码。 by default this feature is disabled to prevent security issues. 默认情况下,禁用此功能以防止安全问题。 (more reading her and her ) (更多阅读她的文章

1) create a filter : 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) use the filter in the view : 2)在视图中使用过滤器:

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