VBA 代码在调试模式下工作，但在运行模式下失败

Question

我正在尝试在 Internet Explorer 中填写一个输入字段，但代码仅在调试模式下工作，而我在每个操作上都按 F8。当我自动运行代码时，值填充不起作用，输入字段保持为空。

可能是什么问题？

这是代码的 HTML 部分：

<input tabindex="0" class="select__input" type="text">
</div>
      <div class="sm__amount" name="payment">
          <div class="sm__send">
              <div class="amount selected" id="amount_get">
                   <div class="amount__field">
                      <div class="amount__label selected">Send amount</div>
      <input id="input-amount_get" type="text" value="" autoComplete="off">
                      </div>
                      <div class="amount__select" id="amount-select">
                          <div class="amount__select__value">
                             XXX
                              <div class="amount__select__trl"></div>
                           </div>
                           <div class="amount__select__box">
                               <div id="currency-XXX" data-v="XXX">XXX</div>
                               <div id="currency-XXX" data-v="XXX"XXX</div>
                     </div>
               </div>
         </div>
  </div>

我正在尝试使用 ID input-amount_get 填写该字段

以下是我尝试过的选项，我注释掉了其他选项，因为它们没有帮助。正如我所说，当我使用 F8 浏览这部分代码时，它工作得很好。

 Application.Wait (Now + TimeValue("0:00:03"))
    'objIE.document.getElementById("input-amount_get").Focus
    'objIE.document.getElementsByTagName("input")(1).innerText = "500"
    objIE.document.getElementById("input-amount_get").innerText = "500.00"
    'objIE.document.getElementById("input-amount_get").Click
    'objIE.document.getElementById("input-amount_get").FireEvent ("onchange")
    Application.Wait (Now + TimeValue("0:00:05"))

这是我正在使用的完整代码：

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

    Dim objIE As InternetExplorer
    Dim doc As HTMLDocument
    Dim el As Object


    Set objIE = New InternetExplorer

    objIE.Visible = True

    objIE.navigate "Website"

    Do While objIE.Busy = True Or objIE.readyState <> 4: DoEvents: Loop

    Do
        Set el = Nothing
        On Error Resume Next
        Set el = objIE.document.getElementById("login")
        On Error GoTo 0
        DoEvents
        Sleep 500
    Loop While el Is Nothing


    objIE.document.getElementById("login").Click

    Do While objIE.Busy = True Or objIE.readyState <> 4: DoEvents: Loop

     Set doc = objIE.document


    objIE.document.getElementsByTagName("input")(0).innerText = "email@email.com"

    objIE.document.getElementsByTagName("input")(3).innerText = "Password"

    objIE.document.getElementsByClassName("button submit")(0).Click


    Do

        On Error Resume Next
        Set el = objIE.document.getElementById("account_menu")
        On Error GoTo 0
        DoEvents

        DoEvents
        Sleep 1000
    Loop While Not (el Is Nothing)

    Do Until objIE.readyState <> 4: DoEvents: Loop

    Application.Wait (Now + TimeValue("0:00:03"))
    DoEvents
    objIE.document.getElementById("input-amount_get").innerText = "500.00"
    Application.Wait (Now + TimeValue("0:00:05"))

    Do

        On Error GoTo 0
        DoEvents
        Sleep 500
    Loop While Not (el Is Nothing)

    Application.Wait (Now + TimeValue("0:00:03"))
    objIE.document.getElementsByName("button_submit")(0).Click


    objIE.Quit

End Sub

Answer 1

将DoEvents 放在您现在的延迟位置。这可能会从调试中重现这种情况。

Answer 2

所以最后在尝试了各种解决方案后，我发现不知何故代码运行得比它应该的要快。我设法通过添加一些额外的等待语句来解决这个问题。我也使用单独的 Private Sub 来设置延迟：

Private Sub delay(seconds As Long)
    Dim endTime As Date
    endTime = DateAdd("s", seconds, Now())
    Do While Now() < endTime
        DoEvents
    Loop
End Sub

输入文本的代码行现在看起来像：

DoEvents 'not necessary, but I left it just in case
delay 4
objIE.document.getElementById("input-amount_get").innerText = "500"

当到达这些行时，代码会再等待 4 秒，然后将值设置为 500。
