最近项目要实现一个新闻发布的功能,要实现图文混排存储入数据库,再取出来进行页面展示的效果,于是网上搜了一个资料,在这里做一下总结,百度富文本编辑器有Java,php,.net三个版本,这里我下载的.net版本的,下载地址:http://ueditor.baidu.com/website/download.html
1、下载后要先看一下ueditor.config.js和asp/config.json的文件,里面是关于图片上传和其他方法的一些路径配置:
ueditor.config.js文件:
上传图片路径的配置文件asp/config.json
2、显示编辑页面(一定要看使用文档:http://fex.baidu.com/ueditor/#server-deploy)
(1)引入所需要的js文件
<script type="text/javascript" charset="utf-8" src="ueditor.config.js"></script>
<script type="text/javascript" charset="utf-8" src="ueditor.all.js"> </script>
<!--建议手动加在语言,避免在ie下有时因为加载语言失败导致编辑器加载失败-->
<!--这里加载的语言文件会覆盖你在配置项目里添加的语言类型,比如你在配置项目里配置的是英文,这里加载的中文,那最后就是中文-->
<script type="text/javascript" charset="utf-8" src="lang/zh-cn/zh-cn.js"></script>
(2)初始化编辑器,html代码:
<div>
<textarea class="A4page" id="myEditor" name="NewsContent"></textarea>
</div>
JavaScript代码:
<!-- 实例化编辑器 -->
<script type="text/javascript">
var ue = UE.getEditor('myEditor', {
toolbars: [
['fullscreen', 'source', '|', 'undo', 'redo', '|',
'bold', 'italic', 'underline', 'fontborder', 'strikethrough', 'superscript', 'subscript', 'removeformat', 'formatmatch', 'autotypeset', 'blockquote', 'pasteplain', '|', 'forecolor', 'backcolor', 'insertorderedlist', 'insertunorderedlist', 'selectall', 'cleardoc', '|',
'rowspacingtop', 'rowspacingbottom', 'lineheight', '|',
'customstyle', 'paragraph', 'fontfamily', 'fontsize', '|',
'directionalityltr', 'directionalityrtl', 'indent', '|',
'justifyleft', 'justifycenter', 'justifyright', 'justifyjustify', '|', 'touppercase', 'tolowercase', '|',
'link', 'unlink', 'anchor', '|', 'imagenone', 'imageleft', 'imageright', 'imagecenter', '|',
'simpleupload', 'insertimage', 'emotion', 'scrawl', 'insertframe', 'insertcode', 'pagebreak', 'template', 'background', '|',
'horizontal', 'date', 'time', 'spechars', 'snapscreen', 'wordimage', '|',
'inserttable', 'deletetable', 'insertparagraphbeforetable', 'insertrow', 'deleterow', 'insertcol', 'deletecol', 'mergecells', 'mergeright', 'mergedown', 'splittocells', 'splittorows', 'splittocols', 'charts', '|',
'print', 'preview', 'searchreplace', 'help', 'drafts']
],
allHtmlEnabled: false,//提交到后台的数据是否包含整个html字符串
autoHeightEnabled: false,
autoFloatEnabled: true,
allowDivTransToP: false//阻止div标签自动转换为p标签
});
</script>
说明修改配置项的方法:
方法一:修改ueditor.config.js里面的toolbars
方法二:实例化编辑器的时候传入toolbars参数(详情参考:http://fex.baidu.com/ueditor/#start-toolbar)
3、前端配置基本上配置好了,下面是后端配置(如果后端配置不好,上传图片功能将无法使用),在提交内容的时候我也遇到了一个坑了我一天的问题,由于是.NET的WinForm,点击按钮提交的时候,页面会整个刷新,所以富文本框内输入的值,由于页面的刷新传入后端的会是空值,我这里解决的方法是把富文本编辑器的赋值语句写到一个js的方法里面,然后把值存到一个隐藏域里面,把提交按钮放到UpdatePanel里面,只刷新按钮,不刷新页面其他部分,点击按钮执行提交之前,先执行这个js方法,取到富文本编辑器里面的值以后再执行存储数据库的操作,具体代码如下:
news_publish.aspx
<%@ Page ValidateRequest="false" Title="新闻发布" Language="C#" MasterPageFile="~/LJMB/MB01/MP01.master" AutoEventWireup="true" CodeFile="news_publish.aspx.cs" Inherits="LJWY_MG00_news_publish" %>

<!--建议手动加在语言,避免在ie下有时因为加载语言失败导致编辑器加载失败-->
<!--这里加载的语言文件会覆盖你在配置项目里添加的语言类型,比如你在配置项目里配置的是英文,这里加载的中文,那最后就是中文-->
