I have to click a HTML button programatically which is on the 3rd page of the website . The button is without id. It has just name type and value . The HTML code of the button is given below
<FORM NAME='form1' METHOD='post' action='/dflogin.php'><INPUT TYPE='hidden' NAME='txtId' value='E712050-15'><INPUT TYPE='hidden' NAME='txtassId' value='1'><INPUT TYPE='hidden' NAME='txtPsw' value='HH29'><INPUT TYPE='hidden' NAME='txtLog' value='0'><h6 align='right'><INPUT TYPE='SUBMIT' NAME='btnSub' value='Next' style='background-color:#009900; color:#fff;'></h6></FORM>
i am using the following code to click it
For Each webpageelement As HtmlElement In allButtons
If webpageelement.GetAttribute("value") = "Next" Then
webpageelement.InvokeMember("click")
End If
Next
But i cant able to click it . I am using the vb.net 2008 platform. Can anyone tell me the solution to click it?
I was having the same problem as you. The InvokeMember looks correct so I can only assume its not picking up the correct html element. Try refering to the element explicitly using the value. The following code worked for me but I have adapted it for you:
For Each webpageelement As HtmlElement In allButtons
If webpageelement.GetAttribute("value").Equals("E712050-15") Then
webpageelement.InvokeMember("click")
Exit For
End If
Next
Good Luck :)

I am trying to click a string of text within a web browser control that runs some javascript, I am unsure how to click the text as the method I use for buttons does not work in this instance
Function Clk(WebBrowserID, ElementID)
WebBrowserID.Document.GetElementById(ElementID).InvokeMember("click")
Return "Clicked"
End Function
This is all that is visible to the client in regards to the clickable text
<div class="task-skip pure-g">
<div class="pure-u-1">
Next
</div>
</div>
I am completely lost on how to either click the text so that the javascript script runs or to invoke the script through code so the button does not need to be pressed, any help would be greatly appreciated.
The solution that I found and worked is as below hope this will help anyone else with the issue.
For Each Element As HtmlElement In Browser.Document.All
If Element.InnerText = "TEXT HERE" Then
Element.InvokeMember("click")
End If
Next
Return "RETURN VALUE"
I cannot simulate a click event on a div element. The HTML code is this one:
<div id="export" data-export="true" data-timespan="">
<button class="btn btn-default ladda-button" type="button" data-style="expand-right" data-spinner-color="#8899a6">
<span class="Icon Icon--featherDownload"></span>
<span class="ladda-label">
Exportar datos
</span>
<span class="ladda-spinner"></span></button>
<div class="hidden error server Callout Callout--danger">
<p>Ocurrió un problema al exportar tus datos, inténtalo de nuevo más tarde.</p>
</div>
</div>
In the webpage, is just a button that downloads a file when clicked. There is no URL. But after checking the code, is the div element what triggers the click event. Look the image.
Click to see image
That "g.handle" triggers a js.file form the website.
My vba code works perfect for doing other stuff in the website, but I cannot accomplish this task.
I've tried all this options:
Set div = HTMLDoc.getElementById("export")
div.FireEvent ("onclick")
div.Click
HTMLDoc.all.Item
Call HTMLDoc.parentWindow.execScript("g.handle", "JavaScript")
Nothing works. I'm kind of blocked right now and I have no idea of how to proceed. Maybe this has no solution? I have almost no idea of HTML and I have 0 idea of Javascript. But it must have a solution, because if I do it manually, i click on that DIV, wait some seconds and download my file.
Thanks in advance. Any help is welcome.
You didn't specify if the highlighted portion was the html code for the button or not, but it appears from looking at it that it isn't.
You can grab the class name for your button. The name may or may not be unique, and it's difficult to know that without seeing the entire html code, but you can set the btn variable below to the first instance of that class name. If there are multiple class names in your html code, then you will need to use a For Each...Next statement to iterate through them (unless you know the instance number off hand).
So we will go with the first instance of your class, hence the reason for the (0) appended on the end.
Sub Test()
Dim ie As New InternetExplorer, HTMLDoc As HTMLDocument, btn As Object
ie.navigate Url 'whatever this may be
' Some code to wait for your page to fully load
Set HTMLDoc = ie.document
Set btn = HTMLDoc.getElementsByClassName("btn btn-default ladda-button")(0)
btn.Click
End Sub
I know this question has been asked many times and I have tried quite a few and none work.
I have a WebBrowser and 1 button. When I click the form button it needs to invoke a click on the WebBrowser button.
I have tried
WebBrowser1.Document.All("start-button").InvokeMember("click")
WebBrowser1.Document.GetElementById("convert1").InvokeMember("Click")
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("a")
If element.GetAttribute("id") = "convert1" Then
element.InvokeMember("click")
End If
Next
None of the above works.
Link to website
Code from the webpage source
<a class="start-button" href="javascript:;" id="convert1" onmouseover="changeImage(this, '');" onmouseout="changeImage(this, '');">
Start
<i class="fa fa-angle-right fa-5"></i>
</a>
Also the button on the WebBrowser, when I click it nothing happens for some reason.
Any help would be great.
Thanks
I have been trying to 'click' a button on a site , but I can't get it working.
This is the button I'm talking about:
<div data-expected-currency="1" data-asset-type="T-Shirt" class="PurchaseButton btn-medium btn-primary" data-se="item-buyforfree" data-item-name="Yoshi tux" data-item-id="1788861" data-expected-price="0" data-product-id="231582" data-expected-seller-id="78049" data-bc-requirement="0" data-seller-name="robosapien626">
Take One
</div>
This is what I'm trying:
For Each elem As HtmlElement In WebBrowser1.Document.GetElementsByTagName("div")
If elem.InnerText.Trim = "PurchaseButton btn-medium btn-primary" Then
elem.InvokeMember("click")
End If
Next
It does not do anything.
Other buttons with an actual ID do work fine.
You have to use GetAttribute after the tag name so you can find the button and click it:
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("div")
If element.GetAttribute("class") = "PurchaseButton btn-medium btn-primary" Then
element.InvokeMember("click")
End If
Next
The .InnerText of that element is Take One with some whitespace around it, so you can try
If elem.InnerText.Trim = "Take One" Then
or
If elem.OuterHtml.Contains("PurchaseButton btn-medium btn-primary") Then
There is a website which has 4 web pages. On first page there is a button, On 2nd page there are also some buttons, on 3rd page there is also a single button, and 4th page also contained a single button. Problem is that my code programmatically clicks the button of first page 2nd page and 3rd page. But is is not clicking the button on 4th page programmatically. How can I enable my code to do that? Please suggest a reliable solution for this .. The HTML code of the button is given below
<FORM NAME='form1' METHOD='post' action='/dflogin.php'><INPUT TYPE='hidden' NAME='txtId' value='E712050-15'><INPUT TYPE='hidden' NAME='txtassId' value='1'><INPUT TYPE='hidden' NAME='txtPsw' value='HH29'><INPUT TYPE='hidden' NAME='txtLog' value='0'><h6 align='right'><INPUT TYPE='SUBMIT' NAME='btnSub' value='Next' style='background-color:#009900; color:#fff;'></h6></FORM>
This code clicks a button programmatically, you should be able to adapt this to what you need and hopefully it should work for you.
For Each webpageelement As HtmlElement In allButtons
If webpageelement.GetAttribute("value").Equals("Next") Then
webpageelement.InvokeMember("click")
Exit For
End If
Next
