ng-bind-html无法正常工作

Question

a.html

<div ng-bind-html="htmlElement()"></div>

controller.js

$scope.htmlElement = function(){ 
  var html = '<input type="text" ng-model="myModel" />'; 
  return $sce.trustAsHtml(html);
}

But when I want to get the value of the text input using

alert($scope.myModel);

It says myModel is undefined. It only happens when I add the text input dynamically.

How can I get the value of that text input?

Answer 1

I suggest you use this DOM manipulation with directive instead.

In your controllers.js :

app.directive("myHtml", function(){
   return {
       restrict: 'E',
       template: '<input type="text" ng-model="myModel" />',
       link: function(scope, attr){
           scope.myModel = 'Input text here';
       }
   } 
});

app.controller('listCtrl', function($scope) {  

    $scope.showInputText = function(){
        alert($scope.myModel);
    }
});

In your HTML :

<div ng-controller="myCtrl">
    <my-html><my-html>
    Your input: {{myModel}}
    <button ng-click="showInputText()">Show Input Text</button>
</div>

try this, http://plnkr.co/edit/A4HRCuTbJt21wEngH9HX?p=preview :

   <div ng-bind-html="htmlElement()" compile-element></div>

....

    module.directive("compileElement", function($compile){
      return {
        link: function(scope,element) {
          scope.$watch(function(){
            return element.html();
          }, function() {
            $compile(element.contents())(scope);
          }); 
        }
      };
    });
