参考博文：【实践】获取CKEditor的html文本、纯文本、被选中的内容及赋值
1、获取CKEditor被选中的内容
var mySelection = CKEDITOR.instances.WORK_INTRODUCTION.getSelection();
if (CKEDITOR.env.ie) {
mySelection.unlock(true);
data = mySelection.getNative().createRange().text;
} else {
data = mySelection.getNative();
}
2、获取CKEditor纯文本
var CText=CKEDITOR.instances.WORK_INTRODUCTION.document.getBody().getText(); //取得纯文本
3、获取CKEditor带HTML标签的文本
var CHtml= CKEDITOR.instances.WORK_INTRODUCTION.getData();
4、给CKEditor赋值
CKEDITOR.instances.WORK_INTRODUCTION.setData("要显示的文字内容");
我的写法：
html中：
<asp:TextBox ID="txt_ProjectIntroduce" runat="server" TextMode="MultiLine" class="ckeditor" onKeyUp="isProjectIntroduceNull();" onblur="isProjectIntroduceNull();"></asp:TextBox> ???????????????????????????????????<script type="text/javascript"> ???????????????????????????????????????if (typeof CKEDITOR == ‘undefined‘) { ???????????????????????????????????????????document.write(‘加载CKEditor失败‘); ???????????????????????????????????????} ???????????????????????????????????????else { ???????????????????????????????????????????var editor_ProjectIntroduce = CKEDITOR.replace(‘txt_ProjectIntroduce‘); ?????????// 创建编辑器 ???????????????????????????????????????????CKFinder.setupCKEditor(editor, ‘../../PlugIns/ckfinder/‘); ??// 为编辑器绑定"上传控件" ???????????????????????????????????????}js脚本：str = CKEDITOR.instances.<%= txt_ProjectIntroduce.ClientID %>.document.getBody().getText(); //取得纯文本 ?????????????//str 长度默认为 1 ?????????????//alert("11" + str+ "22" + str.length ); ?????????????if (str.length <2) { ?????????????????strSummary = strSummary + "项目介绍不能为空！"; ?????????????}JS获取CkEditor在线编辑的内容
