wangEditor基于javascript和css开发的 Web富文本编辑器， 轻量、简洁、易用、开源免费

 

开发文档、demo、下载地址：http://www.wangeditor.com/

 

效果展示：

一：引入js

<script type="text/javascript" src="./js/jquery.min.js"></script>
<script type="text/javascript" src="./js/wangEditor/release/wangEditor.min.js"></script>

 

二：定义dom容器

<div id="div1" class="toolbar"></div>
<div style="padding: 5px 0; color: #ccc"></div>
<div id="div2" class="text">
	<p>请在此输入内容</p>
</div>

 

三：定义样式

.toolbar {
	border: 1px solid #ccc;
	width: 800px;
}

.text {
	border: 1px solid #ccc;
	height: 400px;
	width: 800px;
}

 

四：js代码

    var E = window.wangEditor
	var editor = new E('#div1', '#div2') // 两个参数也可以传入 elem 对象，class 选择器
	//开启debug模式
	editor.customConfig.debug = true;
	// 关闭粘贴内容中的样式
	editor.customConfig.pasteFilterStyle = false
	// 忽略粘贴内容中的图片
	editor.customConfig.pasteIgnoreImg = true
	// 使用 base64 保存图片
	//editor.customConfig.uploadImgShowBase64 = true

	// 上传图片到服务器
	editor.customConfig.uploadFileName = 'myFile'; //设置文件上传的参数名称
	editor.customConfig.uploadImgServer = 'upload.do'; //设置上传文件的服务器路径
	editor.customConfig.uploadImgMaxSize = 3 * 1024 * 1024; // 将图片大小限制为 3M
	//自定义上传图片事件
	editor.customConfig.uploadImgHooks = {
		before : function(xhr, editor, files) {
			
		},
		success : function(xhr, editor, result) {
			console.log("上传成功");
		},
		fail : function(xhr, editor, result) {
			console.log("上传失败,原因是"+result);
		},
		error : function(xhr, editor) {
			console.log("上传出错");
		},
		timeout : function(xhr, editor) {
			console.log("上传超时");
		}
	}

	editor.create()

 

五：服务器代码

导入依赖：

<dependency>
	<groupId>commons-fileupload</groupId>
	<artifactId>commons-fileupload</artifactId>
	<version>1.3.1</version>
</dependency>

 Springmvc配置文件中添加文件上传解析器：

<!-- springmvc文件上传解析器 -->
<bean id="multipartResolver"
	class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
	<property name="defaultEncoding" value="UTF-8" />
	<property name="maxUploadSize" value="-1" />
</bean>

 

pojo：

import java.util.Arrays;

public class WangEditor {
	
	private Integer errno; //错误代码，0 表示没有错误。
	private String[] data; //已上传的图片路径
	
	public WangEditor() {
		super();
	}
	public WangEditor(String[] data) {
		super();
		this.errno = 0;
		this.data = data;
	}
	public Integer getErrno() {
		return errno;
	}
	public void setErrno(Integer errno) {
		this.errno = errno;
	}
	public String[] getData() {
		return data;
	}
	public void setData(String[] data) {
		this.data = data;
	}
	@Override
	public String toString() {
		return "WangEditor [errno=" + errno + ", data=" + Arrays.toString(data)
				+ "]";
	}
	

}
