JavaScript returning empty string

Posted on by DB922

Hello,

I am trying to get the URL to a file on a webpage using a JavaScript setp in Power Desktop Automate.

The URL is that of the icon show below :

To do so, I tried writing a JavaScript step as follows:

var dllink = window.location.origin + document.querySelector("#container > div > div > div.page.p-conso > div.table.table-facture > div > div:nth-child(1) > div:nth-child(3) > a").getAttribute("href");
WScript.echo(dllink);

Executing in the chrome console the variable, i.e. just :

window.location.origin + document.querySelector("#container > div > div > div.page.p-conso > div.table.table-facture > div > div:nth-child(1) > div:nth-child(3) > a").getAttribute("href")

Gives out the correct link.

However, when I try to display the %JavascriptOutput% in a message box, it comes out empty.

Would you have any idea why this JavaScript is not working in Power Desktop Automate while working in the Chrome console ?

I'd be very grateful if someone had a solution to my problem. Thank you in advance.

Hi @DB922

Several members on the forum have been having this issue of javascript returning nothing. Not sure if its a bug in PAD.
However, since its a webpage could you try spying that file icon element and see if it gives the url in the attributes section of the selectors. It should give. And then using a loop iterate through all the file icons on that page.

I'm running into the same problem with both VBScript and Javascript.  I'm not using a webpage; I just tried basic Hello World stuff:
Javascript&colon;
var strFile = "test";
wScript.Echo(strFile);
Console.Write(strFile);
alert(strFile);
return(strFile);

VBscript&colon;
function test()
    print "Test1"
    WScript.Echo "Test2"
    return "Test3"
end function

in the vain hope that one of them would produce a result. Is there some special format or special variable that the output has to come back with?
