我使用
Vojta’s angularJS directive,但有时ckeditor将无法显示服务中的数据.这几乎从来没有发生在刷新,但通常发生在导航回页面.我能够验证$render函数总是使用正确的数据调用ck.setData,但有时它不会显示.
看来,$render方法有时在ckeditor准备好之前被调用.我可以通过添加一个监听器到instanceReady事件来解决这个问题,以确保它在ckeditor准备就绪后至少被调用一次.
ck.on('instanceReady',function() {
ck.setData(ngModel.$viewValue);
});
为了完整起见,这里是我使用的完整指令.
//Directive to work with the ckeditor
//See https://stackoverflow.com/questions/11997246/bind-ckeditor-value-to-model-text-in-angularjs-and-rails
app.directive('ckEditor',function() {
return {
require: '?ngModel',link: function(scope,elm,attr,ngModel) {
var ck = CKEDITOR.replace(elm[0],{
toolbar_Full:
[
{ name: 'document',items : [] },{ name: 'clipboard',items : [ 'Cut','Copy','Paste','PasteText','PasteFromWord','-','Undo','Redo' ] },{ name: 'editing',items : [ 'Find','Replace','SpellChecker','Scayt' ] },{ name: 'forms',{ name: 'basicstyles',items : [ 'Bold','Italic','Underline','Strike','Subscript','Superscript' ] },{ name: 'paragraph',items : [
'NumberedList','BulletedList','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock' ] },{ name: 'links',{ name: 'insert',items : [ 'SpecialChar' ] },'/',{ name: 'styles',items : [ 'Styles','Format','Font','FontSize' ] },{ name: 'colors',{ name: 'tools',items : [ 'Maximize' ] }
],height: '290px',width: '99%'
}
);
if (!ngModel) return;
//loaded didn't seem to work,but instanceReady did
//I added this because sometimes $render would call setData before the ckeditor was ready
ck.on('instanceReady',function() {
ck.setData(ngModel.$viewValue);
});
ck.on('pasteState',function() {
scope.$apply(function() {
ngModel.$setViewValue(ck.getData());
});
});
ngModel.$render = function(value) {
ck.setData(ngModel.$viewValue);
};
}
};
});
