Is it possible to apply two way binding to a <textarea></textarea> that has had TinyMCE applied to it for Rich Text Formatting.
I can't get it to work! I can get TinyMCE to load the content of my model, but when I update the text in TinyMCE, my model does not auto update!
Is there a way?
You can do this by creating your own directive.
What you need to do is to let your directive sync your model when something in the TinyMCE editor changes. I have not used TinyMCE, but Wysihtml5. I think you can remake this to use TinyMCE instead.
angular.module('directives').directive('wysihtml5', ['$timeout',
function ($timeout) {
return {
restrict: 'E',
require: 'ngModel',
template: "<textarea></textarea>", // A template you create as a HTML file (use templateURL) or something else...
link: function ($scope, $element, attrs, ngModel) {
// Find the textarea defined in your Template
var textarea = $element.find("textarea");
// When your model changes from the outside, use ngModel.$render to update the value in the textarea
ngModel.$render = function () {
textarea.val(ngModel.$viewValue);
};
// Create the editor itself, use TinyMCE in your case
var editor = new wysihtml5.Editor(textarea[0],
{
stylesheets: ["/style.css"],
parserRules: wysihtml5ParserRules,
toolbar: true,
autoLink: true,
useLineBreaks: false,
});
// Ensure editor is rendered before binding to the change event
$timeout(function () {
// On every change in the editor, get the value from the editor (textarea in case of Wysihtml5)
// and set your model
editor.on('change', function () {
var newValue = textarea.val();
if (!$scope.$$phase) {
$scope.$apply(function () {
ngModel.$setViewValue(newValue);
});
}
});
}, 500);
}
};
}]);
Then you can use the directive in your html page like this:
<wysihtml5 ng-model="model.text" />
Here's a link if you need more info on creating your own directive: http://docs.angularjs.org/guide/directive
Also compare the render function from the directive above to this render function from angular-ui-tinymce ( https://github.com/angular-ui/ui-tinymce )
ngModel.$render = function() {
if (!tinyInstance) {
tinyInstance = tinymce.get(attrs.id);
}
if (tinyInstance) {
tinyInstance.setContent(ngModel.$viewValue || '');
}

However depending on the timing of the loading of your DOM you may need to set the priority on your directive upwards. :-)
Here is my solution using a custom angular directive. You'll need to use jQuery with angularJS, TinyMCE 4 and their jQuery plugin.
myApp.directive('tinymce', function() {
return {
restrict: 'C',
require: 'ngModel',
link: function(scope, element, attrs, modelCtrl) {
element.tinymce({
setup: function (e) {
e.on("change", function() {
modelCtrl.$setViewValue(element.val());
scope.$apply();
}
}
});
}
}
}
Then in your HTML:
<textarea class="tinymce" ng-model="data"></textarea>
That's it, have fun.
