Question

我正在尝试查看我的tinyMCE在写作时是否有内容，如果是或不设置标志（我正在使用AngularJS）。所以这是我用于微小的代码：

$scope.tinyHasContent = false;
tinymce.init({
                selector: "#elm1",
                height: 400,
                language:'it',
                plugins: [
                    "advlist autolink link image lists charmap print preview hr anchor pagebreak spellchecker",
                    "searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking",
                    "save table contextmenu directionality emoticons template paste textcolor"
                ],
                content_css: "css/partials/content.css",
                toolbar: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image | print preview media fullpage",
                style_formats: [
                    {title: 'Bold text', inline: 'b'},
                    {title: 'Red text', inline: 'span', styles: {color: '#ff0000'}},
                    {title: 'Red header', block: 'h1', styles: {color: '#ff0000'}},
                    {title: 'Example 1', inline: 'span', classes: 'example1'},
                    {title: 'Example 2', inline: 'span', classes: 'example2'},
                    {title: 'Table styles'},
                    {title: 'Table row 1', selector: 'tr', classes: 'tablerow1'}
                ],
                setup : function(ed){
                    ed.on('NodeChange', function(e){

                        if(ed.getContent() != '' || ed.getContent() != undefined || ed.getContent() != null) {
                            $scope.tinyHasContent = true;
                            console.log('the content ' + ed.getContent() + " " + $scope.tinyHasContent);
                        } else {
                            $scope.tinyHasContent = false;
                            console.log('the content ' + ed.getContent() + " " + $scope.tinyHasContent);
                        }
                    });
                }
            });

简单地说，在输入时我可以看到日志我在写什么。但问题是，即使在init上也总是有内容，因为它在日志中总是返回$ scope.tinyHasContent = true。怎么可能？

总而言之，这就是我应该做的事情：

<div ng-if="tinyHasContent == false">
 <p>Hello</p>
</div>

但实际上它不起作用

即使你没有输入任何内容，public class Destroyable : MonoBehaviour { public void DestroyMe() { Destroy(gameObject); } }也会返回 - 默认的根块元素（即段落）。这就是ed.getContent()永远为真的原因。

要验证这一点，您可能需要将tinyHasContent打印到控制台。
