Layui多图片上传前台遍历显示与删除操作

Layui文件上传以及图片回显

var uploadInst = upload.render({
			elem: '#pic',
			//绑定的元素
			url: 'jjsk/curriculum/uploadCurriculumPic?access_token=' + layui.data('layuiAdmin').access_token,
			auto: true,
			//是否自动上传
			accept: "images",
			//指定允许上传的文件类型
			multiple: true,
			//支持多文件上传
			/* size: 1024 * 2, */
			done: function(res, index, upload) { //假设code=0代表上传成功
				if (isObjNotEmpty(res.data)) {
					//上传成功后返回的文件路径
					var fileurl = res.data[0].fileurl;
					//原内容
					var old_url = $("#pic_src").val();
					//判断是否有原内容
					if(old_url.length>0){
			   			$("#pic_src").val( old_url + "," + fileurl);
			   		}else{
			   			$("#pic_src").val(fileurl);
			   		}
					$("#icon_data_div").empty();
					//获取input中存入的地址
					var type_pic_url = $("#pic_src").val();
			   		var strs = new Array();
			   		strs = type_pic_url.split(",");
					//图片回显
			   		var html = "";
			   		for(var i=0;i删除

"; } $("#icon_data_div").html(html); } } });

删除上传图片

function delFile(obj,file){
	//obj为当前对象，file为该文件路径
	$(obj).siblings().remove();
	$(obj).remove();
	//获取全部文件路径
    var files = $("#pic_src").val();
    //分割
    var fileArray = files.split(",");
    //得到要删除文件路径在全部文件路径中的定位
	var index = fileArray.indexOf(file);
	if (index > -1) {
		//分割字符串
		fileArray.splice(index, 1);
	}
	
	$("#pic_src").val(fileArray);
	
	//后台请求数据
	data={
		xFileName:file,
		access_token:layui.data('layuiAdmin').access_token
	};    	  
	$.post('jjsk/curriculum/delCurriculumPic',data,function(json){
		try {
			n=eval('('+json+')');
		} catch (e) {}
		if(json.success){    		  				
			parent.layer.msg("删除成功");
		}else{
			layer.msg(json.msg);
		}
	});
}

删除文件后台

@RequestMapping("delCurriculumPic")
	@ResponseBody
	public LayuiJson delCurriculumPic(HttpServletRequest request,String xFileName){
		LayuiJson json = new LayuiJson();
		//获得项目发布路径
		String realPath = request.getServletContext().getRealPath("/");
		String fileUrl = realPath + xFileName;
		boolean b1 = FileUtils.lkh_delFile(fileUrl);
		if (b1) {
			json.setSuccess(true);
			json.setMsg("删除成功！");
		}else {
			json.setSuccess(false);
			json.setMsg("删除失败！");
		}
		return json;
	}
