好吧，我很困惑，我已经能够成功地将调整大小的图像/blob 上传到服务器文件夹。The problem is that the image/blob upload is always called blob. 有没有办法在客户端更改名称，或者我应该在服务器 PHP 端更改名称？
如果可以的话，请给我一个例子，这是我用来通信的两个脚本

客户端调整大小

<script>
function handleFiles(){
var dataurl = null;
var filesToUpload = document.getElementById('input').files;
var file = filesToUpload[0];

// Create an image
var img = document.createElement("img");
// Create a file reader
var reader = new FileReader();
// Set the image once loaded into file reader
reader.onload = function(e)
{
    img.src = e.target.result;

    img.onload = function () {
        var canvas = document.createElement("canvas");
        var ctx = canvas.getContext("2d"); …

我在excel VBA中汇总了一个代码.我不是,但是现在已经学习了一段时间,但是我一边学习.我已经在互联网上搜索了很多关于何时声明变量,字符串或整数的信息.但我还没有完全明白.使用下面的代码,我成功地能够执行,而无需声明任何变量.我应该使用的问题Dim var1 to dim var100 or is this just not doing anything

Var1 = frmdriverstep1.Labelpa54.Caption
Var2 = frmdriverstep1.Labelza54.Caption
Var3 = frmdriverstep1.ComboBoxga54.Text
Var4 = frmdriverstep1.ComboBoxna54.Text
Var5 = frmdriverstep1.a54label.Caption


DBFullName = "H:\*************.accdb"

Cs1 = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
    "Data Source=" & DBFullName & ";" & _
    "Persist Security Info=False;"

Set CnnConn = New ADODB.Connection
CnnConn.Open Cs1
'zone1
If Var1 >= "0" Then
Set Rst1 = New ADODB.Recordset
Rst1.Open "Zone1", CnnConn, adOpenKeyset, adLockOptimistic, adCmdTable
Rst1.AddNew
Rst1.Fields("Audit_Date") = vardate
Rst1.Fields("Sequence") = varseq
Rst1.Fields("Style") …
