参考：http://www.foxtable.com/mobilehelp/topics/0140.htm

dim json as string = "{""111"":[36,38,43]}"
Dim jo As JObject = JObject.Parse(json)
Dim ja As JArray = jo("111")
For i As Integer = 0 To ja.Count - 1
Output.Show(ja(i).ToString)
Next

老师我想问一下存入foxtable pictureview里面的图片如何显示到web的表里面

引用同一个图片目录即可，参考：http://www.foxtable.com/mobilehelp/topics/0044.htm

那老师我想问一下我上传图片，如何用foxtable用base64下载下来呢

dim str as string = 接收的base64字符串

Dim bs As Byte() = Convert.FromBase64String(str)

Dim stream As System.IO.Stream = New System.IO.MemoryStream(bs)

Dim bmp As System.Drawing.Bitmap = New System.Drawing.Bitmap(stream)

bmp.save("c:\123.jpg")

<p>点击多图上传，或将文件拖拽到此处</p>

layui.use(['element', 'layer','form','upload'], function(){

var $ = layui.jquery

,layer = layui.layer

,element = layui.element

,upload = layui.upload

,form = layui.from;

//多图片上传

upload.render({

elem: '#test2'

,url: 'xxx.xxx' //改成您自己的上传接口

,multiple: true

,accept:'images'

,exts:'jpg|jpeg|png|gjf|webp|bmp|tif'

,drag:true

,allDone: function(obj){

var txt = "共选择了【"+obj.total+"】张图片，其中，上传成功【"+obj.successful+"】张，失败 <span style='color:red'>【"+obj.aborted+"】 </span>张";

$("#tipTxt").html(txt);

}

,before: function(obj){

//预读本地文件示例，不支持ie8

obj.preview(function(index, file, result){

$('#demo2').append('<img src="'+ result +'" alt="'+ file.name +'" class="layui-upload-img">')

});

}

,done: function(res){

$('#demoText').html('');

//上传完毕

if (res.code == 200) {

layer.msg('上传完毕', {icon: 1});

}

});

我不懂layui是怎么上传的，如果是表单模式，参考：http://www.foxtable.com/bbs/dispbbs.asp?boardid=2&Id=149113
