kindeditor富文本编辑器的使用
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

第四步配置struts2
<action name="fmanage" class="bea.com.Action.filemanage" method="fmanage"> </action>
<action name="uloadondown" class="bea.com.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
});
}
});
