Hi All,

I need VBA to execute JavaScript.  The website I am working on has you put in an account number, then it asks you to click a link called view my account.  I have written code to input the account number, but the code that I wrote to click the link does not work properly.  I clicks the link, but evidently does not run the javascript.  I know this because it tells me the account number is invalid.  The source code for the link is below.

<a href="javascript:CheckAndSubmit( document.frmViewMyAcct )">View My Account</a><br>

The code that I have that clicks the clink is:

IE.document.frmviewmyacct.submit

Which I know is incorrect.

Any help would be greatly appreciated.  Thanks in advance.

Hi,

You can use execScript in VBA to control the Java, for example see http://www.experts-exchange.com/Programming/Languages/Visual_Basic/Q_21057068.html

Thanks for the response,

I tried writing the following:

Call IE.document.execScript("checkandsubmit(document.frmviewmyacct);", "JavaScript")

However, I got the error message below:

Run-time error '438':
Object doesn't support this property or method

Did I write this wrong? or am I possibly missing a reference?  I am currently using Microsoft Internet Controls and Microsoft HTML Objects Library

Thanks.

I assume there is no issue with you posting a link to the site ?

I know this may make it more difficult, but I can't post the site.  It is for a vendor of my company.  Even if I could, you would need an account number to see if it could work anyway.  As you could assume, I deffinately can't post that.  Sorry for making this harder than it needs to be.

Ok - Understood. I don't think we need an account though, any text would do just to test if the button was being run

Do you get any joy by looping through the frames?

Cheers

 On Error Resume Next
 For i = 0 To myIE.Document.frames.length - 1
    Call IE.Document.frames(i).execscript("checkandsubmit(document.frmviewmyacct);", "JavaScript")
    if err.number = 0 then
         exit for
    end if
 Next
 On Error Goto 0

Open in new window

Thanks for the help.  I found that the following code works:

IE.document.parentWindow.execScript "CheckAndSubmit(document.frmViewMyAcct);"
