如何点击无ID网页按钮？点击时报错‘Object doesn't support this property or method’求助

Hey there, let's fix this issue step by step!

First, let's pinpoint the root cause: your current code is trying to click the <i> icon element, but this element doesn't have a Click method. The actual clickable interactive control is its parent <button> tag that wraps the icon.

Problem Code Analysis #

This line in your code is the culprit:

ie.document.getElementsByClassName("button-icon right-offset-5 sp-i-xls-download-grey").Click

getElementsByClassName returns a collection of <i> elements with those class names, and directly calling .Click on this collection (or the element itself) fails because <i> isn't a clickable control.

Fix Solutions #

Here are two reliable ways to resolve this:

Method 1: Target the outer <button> directly

Use querySelector with CSS selectors to precisely locate the button containing your target icon:

Sub test()
 Dim ie As Object
 Set ie = New InternetExplorer
 ie.navigate "http://www.spark-interfax.ru/system/home/card#/company/3411D127F25A45F7ABAB32964A32848D/427"
 ie.Visible = True
 ' Wait for full page load
 While ie.Busy Or ie.readyState < 4: DoEvents: Wend
 ' Optional: Add extra wait for element rendering (avoids race conditions)
 Application.Wait Now + TimeValue("00:00:02")
 
 ' Locate button using CSS selector (targets button with the icon inside)
 ie.document.querySelector("button.js-not-print:has(.sp-i-xls-download-grey)").Click
End Sub

If your IE version doesn't support the :has pseudo-class, use this more basic selector instead:

ie.document.querySelector("button.btn-default.btn-sm.js-not-print").Click

Method 2: Find the <i> element, then click its parent button

If you prefer sticking with getElementsByClassName, first grab the icon element, then navigate to its parent button to trigger the click:

Sub test()
 Dim ie As Object
 Dim iconElement As Object
 Set ie = New InternetExplorer
 ie.navigate "http://www.spark-interfax.ru/system/home/card#/company/3411D127F25A45F7ABAB32964A32848D/427"
 ie.Visible = True
 While ie.Busy Or ie.readyState < 4: DoEvents: Wend
 Application.Wait Now + TimeValue("00:00:02")
 
 ' Get the first matching icon element
 Set iconElement = ie.document.getElementsByClassName("button-icon right-offset-5 sp-i-xls-download-grey")(0)
 ' Click its parent button element
 iconElement.parentElement.Click
End Sub

Extra Tips #

• Sometimes the page finishes loading but elements aren't fully rendered yet. Adding a short wait or a loop to check if the element exists before interacting can prevent unexpected errors.
• When using getElementsByClassName, always specify an index (like (0)) to target a single element—otherwise you'll get errors trying to operate on a collection instead of an individual element.
