这次我是在EasyUI中使用了KindEditor的编辑器，按照官方给的代码，总是无法获取编辑器里面的值（内容），如下： KindEditor.ready(function (K) { var editor1 = K.create(‘#content’, { cssPath: ‘../js/plugins/code/prettify.css’, uploadJson: ‘upload_json.ashx’, fileManagerJson: ‘file_manager_json.ashx’, allowFileManager: true, afterCreate: function () { var self = this; K.ctrl(document, 13, function () { self.sync(); K(‘form[name=example]’)[0].submit(); }); K.ctrl(self.edit.doc, 13, function () { self.sync(); K(‘form[name=example]’)[0].submit(); }); } }); prettyPrint();
});
改代码就是官方给的，后来发现，第二次提交，这个content又有值了，甚是奇怪，后来在百度的帮助下，找到了原因，原理是需要在提交之前，异步一下编辑器的内容，改良后的代码如下： KindEditor.ready(function (K) { var editor1 = K.create(‘#content’, { cssPath: ‘../js/plugins/code/prettify.css’, uploadJson: ‘upload_json.ashx’, fileManagerJson: ‘file_manager_json.ashx’, allowFileManager: true, afterCreate: function () { var self = this; K.ctrl(document, 13, function () { self.sync(); K(‘form[name=example]’)[0].submit(); }); K.ctrl(self.edit.doc, 13, function () { self.sync(); K(‘form[name=example]’)[0].submit(); }); }, afterBlur: function () { this.sync(); }//这一步非常重要，如果遗漏，则后台无法接收到数据。
}); prettyPrint();
});
这样后台就可以正常接收数据了，下面是完整代码，也可以下载附件来看：
