I have a controller MyCtrland a directive myText. When the model in changes MyCtrl, I want to update the directive of the textareadirective myTextby inserting the text in the current position / carriage.
I tried to reuse the code from the Insert text in which the cursor uses Javascript / jquery
My code: http://plnkr.co/edit/WfucIVbls2eekL8kUp7e
Here is my HTML:
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link href="style.css" rel="stylesheet" />
<script data-semver="1.2.10" src="http://code.angularjs.org/1.2.10/angular.js" data-require="angular.js@1.2.x"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="MyCtrl">
<input ng-model="someInput">
<button ng-click="add()">Add</button>
<p ng-repeat="item in items">Created {{ item }}</p>
</div>
<textarea my-text="">
</textarea>
</body>
</html>
JavaScript:
var app = angular.module('plunker', []);
app.controller('MyCtrl', function($scope, $rootScope) {
$scope.items = [];
$scope.add = function() {
$scope.items.push($scope.someInput);
$rootScope.$broadcast('add', $scope.someInput);
}
});
app.directive('myText', ['$rootScope', function($rootScope) {
return {
link: function(scope, element, attrs) {
$rootScope.$on('add', function(e, val) {
console.log('on add');
console.log(val);
if (document.selection) {
element.focus();
var sel = document.selection.createRange();
sel.text = val;
element.focus();
} else if (element.selectionStart || element.selectionStart === 0) {
var startPos = element.selectionStart;
var endPos = element.selectionEnd;
var scrollTop = element.scrollTop;
element.value = element.value.substring(0, startPos) + val + element.value.substring(endPos, element.value.length);
element.focus();
element.selectionStart = startPos + val.length;
element.selectionEnd = startPos + val.length;
element.scrollTop = scrollTop;
} else {
element.value += val;
element.focus();
}
});
}
}
}])
Now this does not work, because it is elementnot a DOM object. Here is the error:
TypeError: Object [object Object] has no method 'focus'
QUESTION: So my question is how to fix this? Or how to get a real DOM object from an angular element object?
