ng-bind-html 不适用于我的 $scope.variable [英] ng-bind-html not working with my $scope.variable

问题描述

我正在尝试使用 ng-bind-html 添加类似动态 HTML 的内容，但它不适用于 $scope 变量

这是我的 Angular 代码

1)我的控制器

$scope.name = "Parshuram"$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml("<div>{{name}}</div>");

而且我的字符串是动态的

"<div><table class=" + "\"table table - 带边框的表格 - 响应式表格 - 悬停添加 - lineheight table_scroll\"" + "><thead><tr><td>姓名</td><td>年龄</td></tr></thead><tbody><tr ng-repeat=" + "\"tr in dyna\""+ "><td>{{tr.name}}</td><td>{{tr.age}}</td></tr></tbody></table>;</div>"

所以我不能用 $scope 替换每个变量

2)- 我的 HTML

<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>

我得到了这个输出

{{name}}

我的预期输出是

帕舒拉姆

请谁能帮我解决这个问题，$sce 没有绑定作用域变量吗??..

问题是 ng-bind-html 没有绑定到作用域.您应该手动编译内容.

一个有效且可重用的解决方案应该是创建一个指令，不使用任何外部模块.

function compileTemplate($compile, $parse){返回 {链接:功能(范围，元素，属性){var parsed = $parse(attr.ngBindHtml);function getStringValue() { return (parsed(scope) || '').toString();}scope.$watch(getStringValue, function() {$compile(element, null, -9999)(scope);});}}}<div ng-app="mymodule" ng-controller="myModuleController"><div ng-bind-html="thisCanBeusedInsideNgBindHtml" 编译模板></div>

I am trying to add something like dynamic HTML using ng-bind-html but its not working with $scope variable

Here is my Angular code

1)My controller

$scope.name = "Parshuram"
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml("<div>{{name}}</div>");

Also that my string is dynamic

"<div><table class=" + "\"table table - bordered table - responsive table - hover add - lineheight table_scroll\"" + "><thead><tr><td>Name</td><td>Age</td></tr></thead><tbody><tr ng-repeat=" + "\"tr in dyna\"" + "><td>{{tr.name}}</td><td>{{tr.age}}</td></tr></tbody></table></div>"

So i cant replace every variable with $scope

2)- My HTML

<div ng-app="mymodule" ng-controller="myModuleController">
    <div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
</div>

I got this output

{{name}}

My expected output is

Parshuram

Please can anyone help i am stuck at this point,does that $sce does not bind scope variable?? ..

I've created a working plnkr here: https://plnkr.co/edit/uOdbHjv1B7fr0Ra1kXI3?p=preview

the problem is that ng-bind-html is not bound to the scope. you should manually compile the content.

a valid and reusable solution should be creating a directive, whitout using any external modules.

function compileTemplate($compile, $parse){
    return {
        link: function(scope, element, attr){
            var parsed = $parse(attr.ngBindHtml);
            function getStringValue() { return (parsed(scope) || '').toString(); }    
            scope.$watch(getStringValue, function() {
                $compile(element, null, -9999)(scope);  
             });
        }
    }
  }




<div ng-app="mymodule" ng-controller="myModuleController">
    <div ng-bind-html="thisCanBeusedInsideNgBindHtml" compile-template></div> 
</div>
