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

那老师我想问一下我上传图片，如何用foxtable用base64下载下来呢

!DOCTYPE html>

<html>

<head>

</head>

<body>

<p>点击多图上传，或将文件拖拽到此处</p>

</div>

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});

}

});

</script>

</html>

老师如何获取这个file

8楼是直接把Dim e As RequestEventArgs = args(0)

Dim wb As New StringBuilder

If e.PostValues.Count = 0 Then

wb.AppendLine("<!DOCTYPE html>")

wb.AppendLine("<html><head>")

wb.AppendLine("<title>图片上上传</title>")

wb.AppendLine("<meta charset='utf-8'>")

wb.AppendLine("<meta name='viewport' c>")

wb.AppendLine("<link rel='stylesheet' href='./web/style.css'>")

wb.AppendLine("<meta http-equiv='Content-Type' c></head><body>")

'''

wb.AppendLine("<form action='tpsc.htm' enctype='multipart/form-data' method='post' id='form1' name='form1'>")

wb.AppendLine("<div class='crd-img'><div class='crd-title'><i class='fl'></i>")

wb.AppendLine("<span class='fl'>照片</span>")

wb.AppendLine("<span class='crd-notice fr'>上传须知</span></div>")

wb.AppendLine("<div class='crd-image'><div><div class='front'>")

wb.AppendLine("<input Type='file' id='front' name='front' accept='image/jpeg,image/png,image/gif' capture='camera'>")

wb.AppendLine("<img src='./web/upload.png' alt='' class='img_upload'>")

wb.AppendLine("<img src='./web/crd_front.jpg' alt='' id='front_img' ></div>")

wb.AppendLine("<div class='contrary'>")

wb.AppendLine("<input Type='file' id='contrary' name='contrary' accept='image/jpeg,image/png,image/gif' capture='camera'>")

wb.AppendLine("<img src='./web/upload.png' alt='' class='img_upload'>")

wb.AppendLine("<img src='./web/crd_contrary.jpg' alt='' id='contrary_img' accept='image/jpg,image/png,image/gif' capture='camera'>")

wb.AppendLine("</div></div></div>")

wb.AppendLine("<div class='crd-tip'><div><span>图片1</span></div>")

wb.AppendLine("<div><span>图片2</span></div>")

wb.AppendLine("</div></div></div>")

wb.AppendLine("<input Type='button' class='btn' name='Sumbit' id='Sumbit' value='确认上传' >")

wb.AppendLine("</form>")

wb.AppendLine("<script src='./web/jquery.min.js' type='text/javascript'></script>")

wb.AppendLine("<script src='./web/upimg.js' type='text/javascript'></script>")

wb.AppendLine("</body></html>")

e.WriteString(wb.ToString)

'''

Else

For Each key As String In e.Files.Keys

For Each fl As String In e.Files(key)

e.SaveFile(key,fl,ProjectPath & fl) '保存接收到的文件

e.WriteString("图片上传成功!")

End If 放进foxtable就行了吗？

For Each key As String In e.Files.Keys

For Each fl As String In e.Files(key)

e.SaveFile(key,fl,ProjectPath & fl) '保存接收到的文件

e.WriteString("图片上传成功!")

function upload(){

var formData = new FormData();

//接口接收参数键值形式添加到formData中

formData.append("front",$("#front")[0].files[0]);

formData.append("contrary",$("#contrary")[0].files[0]);

$.ajax({

url:'http://127.0.0.1/tpsc.htm',//url地址

type:'post',

data: formData,

contentType: false,

processData: false,

success:function(res){

console.log(res);

}

})

}

这两个吗

BASE64转图片 - 站长工具 - 极速数据 (jisuapi.com) 老师我用这个是可以转为图片的，但是我用代码Dim str1 As String = e.postvalues("image")

Dim bs As Byte() = Convert.FromBase64String(str1)

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")

他报错,报错值为：.NET Framework 版本：4.0.30319.42000

Foxtable 版本：2021.10.16.1

错误所在事件：项目,HttpRequest

详细错误信息：

输入的不是有效的 Base-64 字符串，因为它包含非 Base-64 字符、两个以上的填充字符，或者填充字符间包含非法字符。

怎么用代码把data:image/jpeg;base64,/9j/4RIyRXhpZgAAT...............把那个去掉呢

老师下载例如新增一个上传图片到foxtable里面应该怎么放到进去当个新增目标的pictureview里面呢
