what is wrong with my code for invoking a javascript

Question

I am trying to automate downloading pdf documents from a third party web page.

the jscript seciton of the webpage is something like this:

<SCRIPT language=javascript type=text/javascript>

function ns_7_OIK6I940H0J4D0ILE3HAEF1CV6_popViewDocPStmnt(indxCnt){
 var hidRowCounter = document.getElementById("ns_7_OIK6I940H0J4D0ILE3HAEF1CV6_RowCounter");
    var hidRowCounter_nth = document.getElementById("ns_7_OIK6I940H0J4D0ILE3HAEF1CV6_RowCounter"+indxCnt);
    hidRowCounter.value = hidRowCounter_nth.value;
    if (false){
     document.OpenDocForm1.submit();
    } else {
        document.OpenDocForm2.submit();
    } 
}
</SCRIPT>


the input section html for downloading the PDF doc's is like this

<TBODY class=contentframework-stripedtable>

 so in my .net c# app, I parsed  and obtain a string array sReslt of

   scriptname, the argument ( row # between parentheses)

 and for each row I tried to

	object[] arg = new object[1];
	arg[0] = sReslt[i, 1]; 
	string scriptNm = sReslt[i, 0];
	object o = wbctl.getActiveBrowser().Document.InvokeScript(scriptNm, arg);

the resulting object is null and I only get a response windows to save or open for the last one on the list

what can I do to fix the problem?

adding line after the invokescript with thread sleep does not help

Answer 1

Hi,

Your resources are fragmented that we could not get your point.
The control in the following is not given in your html code:
var hidRowCounter = document.getElementById("ns_7_OIK6I940H0J4D0ILE3HAEF1CV6_RowCounter");
And some other staffs are not available too, like OpenDocForm1, OpenDocForm2, etc.
From your description about the C# logics at the end of your original post, I could not get any point on what you are trying to implement.
Thanks for your understanding.

Have a nice day,

all I want is to simulate clicking the each row that will result in downloading and let me enter the required responses.  ( ultimately the complete code should automatcally make available proper file name in clipboard for me to paste into the saving as file windows that will popup, but that is not the problem at the moment)

the problem now is some how only the last one will show up for me to save

there is no room for complete HTML,

I was just illustrating the main point of interest. the complete html is rather long.

here is some of the missing html

Answer 3

there is a more complete html sample on sky drive

Answer 4

Hi,

If I have not got it wrong, the html page you uploaded is the rendered result of your web form. But it won't do any good to our friends here on resolving your problem, you should provide us the web form files(.aspx, .aspx.cs, designer.cs, etc.)

Have a nice day,

Answer 5

thx for responding but l the web page is from a third party, and I can't get the designer, aspx  stuff other just the html,

the complete orginal html had confidential info, so I had to edit to change the address, name,... etc

why it seem to  respond to the last request from script invoke and ignore all prev? is there a way to program the script invoke so each appear to the last one in the series of execution?

or do Id to somehow bypass the script; post the required information like the javascipt does? 

Answer 6

Hi fs-ab,

So what is the C# app you are dealing with? A Winform one? Or a WPF one?
What is sReslt array and what is wbctl.getActiveBrowser()? Seems there isn't one member in .NET framework which provides the implementation of the getActiveBrowser method.
Thanks for your understanding and have a nice day,

Answer 7

thx fot replying, my app is a winform

sReslt array is an array I parsed the required element ID and other paramters I found in the downlaod pdf input and javascript parameter associated.

wbctl.getActiveBrowser() is custom control member which returns the active Browser's DocumentText (html). sorry that I did not point that out

wbCtl derives from a custom class of tabcontrol with a minimum of one tabpage with a webbrowser and directs any new windows request to creating a new tabpage of another webbrowser on the tab control

the array sReslt was found to have the desired content albeit there was need for deduplication code for some pages. I think the 3 party webpage was designed for more than IE and repeat the table of available download somewhat different style for suit the browser

Answer 8

Then you should close this thread and post in the dedicated Windows
Forms General Forum for dedicated support.
Thanks for your understanding and have a nice day,
