Use VBA code to click on a button on webpage
提问by dmr
I am editing a vba program and want to code the vba to click on a button in a webpage. The html for the button is:
我正在编辑一个 vba 程序，并希望对 vba 进行编码以单击网页中的按钮。按钮的 html 是：
<input type="image" src="/lihtml/test_button3.gif" align="left" alt="File_Certificate_Go"/>
I imagine I would have to set a variable to getElementBy??? and then variable.click, but I can't figure out how exactly to get the element (because it doesn't have a name or id, and I can't give it one because it is not my webpage).
我想我必须为 getElementBy 设置一个变量？？？然后是variable.click，但我不知道如何准确地获取元素（因为它没有名称或ID，我不能给它一个，因为它不是我的网页）。
Any help is greatly appreciated!
任何帮助是极大的赞赏！

Perhaps something on the lines of:
也许是这样的：
Set tags = wb.Document.GetElementsByTagname("Input")
For Each tagx In tags
If tagx.alt = "File_Certificate_Go" Then
tagx.Click
End If
Next
Where wb is the WebBrowser control.
其中 wb 是 WebBrowser 控件。

Is there a reason you couldn't give the element an id?
有什么理由不能给元素一个 id 吗？
i.e.:
IE：
<input id='myButton' type=image src="/lihtml/test_button3.gif" align=left alt=File_Certificate_Go>
then:
然后：
document.getElementById('myButton').click()
edit: Based on your comment, you'd have to grab all input elements on the page, and then cycle through them looking for the one that makes your input unique:
编辑：根据您的评论，您必须获取页面上的所有输入元素，然后循环浏览它们以查找使您的输入独一无二的元素：
var elms = document.getElementsByTagName("input");
for (var i=0; i< elms.length; i++)
if(elms[i].src = '/lihtml/test_button3.gif') { elms[i].click(); }
Something along those lines anyway
无论如何
