Simditor图片上传

上篇文章(Simditor使用方法)只是简单的默认配置,我们可自定义工具栏按钮使其更丰富和实现上传图片功能

初始化编辑器

<script type="text/javascript">
   $(function(){
	toolbar = [ 'title', 'bold', 'italic', 'underline', 'strikethrough',
			'color', '|', 'ol', 'ul', 'blockquote', 'code', 'table', '|',
			'link', 'image', 'hr', '|', 'indent', 'outdent' ];
	var editor = new Simditor( {
		textarea : $('#editor'),
		placeholder : '这里输入内容...',
		toolbar : toolbar,  //工具栏
		defaultImage : 'simditor-2.0.1/images/image.png', //编辑器插入图片时使用的默认图片
		upload : {
		    url : 'ImgUpload.action', //文件上传的接口地址
		    params: null, //键值对,指定文件上传接口的额外参数,上传的时候随文件一起提交
		    fileKey: 'fileDataFileName', //服务器端获取文件数据的参数名
		    connectionCount: 3,
		    leaveConfirm: '正在上传文件'
		} 
	});
   })
</script>

upload默认为false,设置为true或者键值对就可以实现上传图片,界面是出来了,还需要进行后台编码(本例为Struts2)

实现功能之前需要修改一下simditor.js,我们可以对"本地图片" 用chrome审查元素发现没有name属性

打开simditor.js找到

return $input = $('<input type="file" title="' + Simditor._t('uploadImage') + '" accept="image/*">').appendTo($uploadItem);这一行,

可以搜索accept="image/*"  快速找到在input里加上 name="fileData"

如下：

return _this.input = $('<input name="fileData" type="file" title="' + Simditor._t('uploadImage') 
+ '" accept="image/*">').appendTo($uploadBtn);

同样继续搜索accept="image/*"  下面还有一个,加上name="fileData"

ImgUploadAction

public class ImgUploadAction extends ActionSupport {  
	private static final long serialVersionUID = 1L;
	private String err = "";  
    private String msg;              //返回信息  
    private File fileData;           //上传文件  
    private String fileDataFileName; //文件名  
  
    public String imgUpload() {  
        //获取response、request对象  
        ActionContext ac = ActionContext.getContext();  
        HttpServletResponse response = (HttpServletResponse) ac.get(ServletActionContext.HTTP_RESPONSE);  
        HttpServletRequest request = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);  
          
        response.setContentType("text/html;charset=gbk");  
          
        PrintWriter out = null;  
        try {  
            out = response.getWriter();  
        } catch (IOException e1) {  
            e1.printStackTrace();  
        }  
  
        String saveRealFilePath = ServletActionContext.getServletContext().getRealPath("/upload");  
        File fileDir = new File(saveRealFilePath);  
        if (!fileDir.exists()) { //如果不存在 则创建   
            fileDir.mkdirs();  
        }  
        File savefile;  
        savefile = new File(saveRealFilePath + "/" + fileDataFileName); 
        try {  
            FileUtils.copyFile(fileData, savefile);  
        } catch (IOException e) {  
            err = "错误"+e.getMessage();  
            e.printStackTrace();  
        }  
        String file_Name = request.getContextPath() + "/upload/" + fileDataFileName;  
        
        msg = "{"success":"" + true + "","file_path":"" + file_Name + ""}";  
        out.print(msg); //返回msg信息  
        return null;  
    }  
  
    public String getErr() {  
        return err;  
    }  
    public void setErr(String err) {  
        this.err = err;  
    }  
    
    public String getMsg() {  
        return msg;  
    }  
    public void setMsg(String msg) {  
        this.msg = msg;  
    }
    
	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;
	}  
}
