如果说用ajax接收的话,在HTML中这样写就可以了 <script type="text/javascript"> KindEditor.ready(function(K){ K.create('textarea[name="content"]', { themeType: 'simple', resizeType: 1, cssPath : 'kindeditor/plugins/code/prettify.css', uploadJson : 'kindeditor/jsp/upload_json.jsp', fileManagerJson : 'kindeditor/jsp/file_manager_json.jsp', allowFileManager: true, //经测试，下面这行代码可有可无，不影响获取textarea的值 // afterCreate: function(){this.sync();} //下面这行代码就是关键的所在，当失去焦点时执行 this.sync(); afterBlur: function(){this.sync();} }); }); </script>
