第一步引入相应的js文件
<!-- 引入kindeditor --><link rel="stylesheet" href="<%=basePath%>kindeditor-4.1.10/themes/default/default.css" /><link rel="stylesheet" href="<%=basePath%>kindeditor-4.1.10/plugins/code/prettify.css" /><script charset="utf-8" src="<%=basePath%>kindeditor-4.1.10/kindeditor.js"></script><script charset="utf-8" src="<%=basePath%>kindeditor-4.1.10/lang/zh_CN.js"></script><script type="text/javascript" src="<%=basePath%>jslib/noRefleshForm.js"></script>
第二步初始化kindeditor
</script><script type="text/javascript"> var editor =null;KindEditor.ready(function(K) {editor= K.create('#kindeditor', {cssPath : '<%=basePath%>kindeditor-4.1.10/plugins/code/prettify.css',uploadJson : '<%=basePath%>uloadondown.action',//上传的请求fileManagerJson : '<%=basePath%>fmanage.action',allowFileManager : true });});</script>//html代码<textarea id="kindeditor" name="data.tcontent"style="width:1000px;height:360px;"></textarea>
第三步写好相应的uploadimg .action和filemanage.action
filemanage

第四步配置struts2
<action name="fmanage" class=".Action.filemanage" method="fmanage"> </action><action name="uloadondown" class=".Action.uploadimg" method="uloadondown"> </action>
这样就可以了
注意
新增时editor.sync();//先同步，才能拿到值
例如`function btn_add_news() {
editor.sync();//先同步，才能拿到值
var dataPara = getFormJson((“#example”));.ajax({
url : “insertNews”,
type : “post”,
data : dataPara,
dataType : ‘json’,
success : function(result) {
if(result.cf=="OK"){ parent.$.messager.alert('提示', "新增成功！");add_dialog.dialog('close');dataGrid.datagrid('load');}else{parent.$.messager.alert('提示', "新增失败！");}}});}`
修改时怎么把后台数据绑定到编辑器中只要一句代码
editor.html(result.tcontent);
例如、
$.ajax({type:"post",url:"getNewForm?id="+id,dataType:"json",success:function(result){$("#example").form('load',result);editor.html(result.tcontent);$('#dd').dialog({ title: '修改新闻', close:false});}});
