利用xhEditor插入图片

xhEditor具备在编辑框中插入图片和音频，但是默认情况时关闭的，可以通过如下形式来实现在编辑框中插入图片并显示在编辑框中。下面实现利用struts上传图片，需要注意的是xhEditor上传图片时参数名为filedata。
1、JSP页面

<textarea class="xheditor {upBtnText:'浏览',upImgUrl:'uploadAction!uploadImg',upImgExt:'jpg,jpeg,gif,png'}"></textarea>

2、action

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletContext;

import org.apache.struts2.ServletActionContext;
import org.springframework.stereotype.Component;

import com.opensymphony.xwork2.ActionSupport;
@Component("uploadAction")
public class UploadAction extends ActionSupport {
	/**
	 * 
	 */
	private static final long serialVersionUID = 7087202718619368736L;
	private File filedata;
	private String filedataFileName;
	private String filedataContentType;
	
	public void uploadImg() {
		ServletContext sc = ServletActionContext.getServletContext();System.out.println(sc.getContextPath());
		if(filedata!=null){
			String dataDir = sc.getRealPath("/images/upload");
			String fileType = filedataFileName.substring(filedataFileName.lastIndexOf("."));
			int na = (int)(Math.random() * 9999.0D);
			String tempName = new Long(System.currentTimeMillis()).toString() + String.valueOf(na) + fileType;
			File savedFile = new File(dataDir, tempName);
			filedata.renameTo(savedFile);
			tempName = sc.getContextPath() + "/images/upload/" + tempName;
			try {
				PrintWriter out = ServletActionContext.getResponse().getWriter();
				out.print("{\"err\":\"\",\"msg\":\"" + tempName + "\"}");
				out.flush();
				out.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
	
	public File getFiledata() {
		return filedata;
	}
	public void setFiledata(File filedata) {
		this.filedata = filedata;
	}

	public String getFiledataFileName() {
		return filedataFileName;
	}

	public void setFiledataFileName(String filedataFileName) {
		this.filedataFileName = filedataFileName;
	}

	public String getFiledataContentType() {

	}
