I’m working on a process in which the robot needs to download some PDFs from a web platform (the number of files can vary from one item to another) and then display them all within one form task (they will serve as an element for decision-making). How can I display all PDF files dynamically?
I was thinking about maybe link the data.variable inside the HTML content with values in dropdown list that will be dynamically populated with the number of PDF file paths downloaded (string variables).
Does anyone have any idea how I could do this please?

I populated a dropdown list with a list of strings (pdf paths). Now, I want to display the selected pdf from the dropdown list in the HTML content (iframe). How can I perform this? Does anyone have any idea which logic should I use to enable this dynamic display?
I do not know if you can do it in an async way (should be definitely possible), but a basic approach would be to create a simple javascript function to toggle a refresh when a selection is made and you could change the link to be accessed. I have used a similar approach (dropdown + iframe for images) with images and a flask server in python, so it should be possible with pdfs too in iframe.
No UiPath licenses were harmed (used) in this approach
Part 1: The input from the user is captured and onchange a javascript function “updatepdf()” is triggered.
<label for="file">Choose a pdf file:</label>
<select name="files" id="selectpdf" onchange=updatepdf()>
<option value="1">Testfile1.pdf</option>
<option value="2">Testfile2.pdf</option>
</select>
Part 3: Lets define the updatepdf() function. Here we get the option number of the choose dropdown value and we use the value of that index (in this case I have used file name with extension) you may need to add the extension string separately depending your code.
The last part is to just change the value of id=“showpdf” iframe to the selected value.
<script>
function updatepdf() {
var e = document.getElementById("selectpdf");
var strUser = e.options[e.selectedIndex].text;
document.getElementById("showpdf").src = strUser;
}
</script>
Here are the demo files and the HTML file: LinkChange.zip (14.0 KB)
Just open the html file and you can test it out. I have used a single file for all HTML, CSS, and Javascript in ChangeLink.html
