源：

<script type="text/javascript">var editor;KindEditor.ready(function(K) {editor = K.create('textarea[name="userinfo.introduce"]', {resizeType : 1,allowPreviewEmoticons : false,allowImageUpload : false,afterCreate : function() {var self = this;self.sync();K.ctrl(document, 13, function() {document.forms['addform'].submit();});K.ctrl(self.edit.doc, 13, function() {document.forms['addform'].submit();});},       items : ['fullscreen','source','preview','|','fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline','removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist','insertunorderedlist', '|', 'emoticons', 'image', 'link']});});
</script>

HTML代码

<textarea name="userinfo.introduce" style="width:700px;height:200px;visibility:hidden;"></textarea>

这样子在后台的strts2的action中拿到的是空。

只有再加上这段语句才可以获得。

afterBlur:function(){ this.sync(); }

加上后：

<script type="text/javascript">var editor;KindEditor.ready(function(K) {editor = K.create('textarea[name="userinfo.introduce"]', {resizeType : 1,allowPreviewEmoticons : false,allowImageUpload : false,afterCreate : function() {var self = this;self.sync();K.ctrl(document, 13, function() {document.forms['addform'].submit();});K.ctrl(self.edit.doc, 13, function() {document.forms['addform'].submit();});},afterBlur:function(){ this.sync(); },       items : ['fullscreen','source','preview','|','fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline','removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist','insertunorderedlist', '|', 'emoticons', 'image', 'link']});});
</script>
