Posted on by pawanrai

As we all know behind the scenes power automate uses jquery selectors for web automation. I was trying to get the elements using jquery selector under step run javascript for web page, in following fashion:

var count = $("ul.class1").childElementCount;

return count

but above code always returns unknown. Whereas same code works on browser console of the respective webpage.

Can anyone suggest what is wrong here.

Thanks

Hi i am also starting at the time , i read yeasterday that only a few selectors are avaliable like :contains . If you have something with text to click or mark the mouse move to text function realy good . The rest i did with keyboard shortcuts tap , windows short cuts . So i didnt need the selectors yet. here is a video https://youtu.be/cgK_BH1gBzc?t=5707 that nice programmer used selectors. What i figured out was espacialy the events from browser automate didnt work good , but the events at the mouse do .

Okay. This is where the issue was. The respective html document was inside an iframe and I was overlooking this fact.

I had to use below js code to reach the respective element:

var iFrameDOM = $("iframe#iframeid").contents();
var li = iFrameDOM.find("li.css-class").length;

The above code worked and gather the correct count.

Hey great you share this , i need to try out 🙂 I start loving Power Automate, it is also possible to record, and record twice and do both in one selection. I made an example page to get css selectors by using power automate. I will update from time to time.

I have a JQuery function I'm trying to implement. The function works fine in the browser console.
But it returns nothing when I execute it in Power Automate Desktop
using the "Execute Javascript function on a web page" action.
So I started playing with just this simple JS function (which also doesn't return anything):
function ExecuteScript() {var data = "This is a test"; return data;}
Any thoughts on what is happening with this action?
I'm dealing with dynamically generated elements on the web page and can't rely on static IDs.
I have to loop through rows of input fields. So having an action to call Javascript or JQuery would be a huge help.
Thanks!

Maybe this is what you searching for WScript.Echo(MyJavascriptVariableForJavascriptOutput);
I don't think you can work with jquery in power automate ! Tried it then. When something looks like jquery it doesn't have the same behavior as on webpages nor the same syntax I think.
// Delete Zero at begining String->var stringel

var stringel="%NewVar%"; // "%InputVariableFromPowerAutomate%";

var replaced = ""+stringel.substring(1);

WScript.Echo(replaced); /* replaced is the javascript variable who will be shown in JavascriptOutput */

Example for Copy Paste into Main ->SET NewVar TO $'''0123004'''
Scripting.RunJavascript JavascriptCode: $'''// Lösche voranstehende Null bzw erstes Zeichen in der Zeichenkette
var stringel=\"%NewVar%\";

var replaced = \"\"+stringel.substring(1);

WScript.Echo(replaced);''' ScriptOutput=> JavascriptOutput ScriptError=> ScriptError<-End of Code
