Use VBA code to click on a button on webpage

Question

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:

<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).

Any help is greatly appreciated!

Answer 1

Perhaps something on the lines of:

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.

Is there a reason you couldn't give the element an id?

i.e.:

<input id='myButton' type=image src="/lihtml/test_button3.gif" align=left alt=File_Certificate_Go> 

then:

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:

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
