A guide to downloading a file linked to Javascript with the help of Java

I have a unique request here. I am looking for a solution using HttpUrlConnection that can interact with JavaScript directly on a webpage, instead of relying on Selenium as a workaround. Can anyone assist me with this?

The webpage contains a link (hidden by an image) as seen below:

     <a .............

     onclick="javascript:downLoad('CAMID(\xxx;)/folder[@name=\'test\']/folder[@name=\'test\']

    /reportView[@name=\'test\']/output[@name=\'test']',

    'spreadsheetML' )" alt="Download" ></a>

When I click on this link, a pop-up window appears and I can then click on the save button.

Is there a way to programmatically download this file using Java without interacting with the pop-up?

Currently, I am using Selenium and Java's Robot object to simulate clicking the save button. However, I believe there should be a direct method to download the file without these workarounds.

Looking for a solution on how to locate and handle a popup window? Check out this helpful guide: Handling a popup window using selenium

Once you've found the popup window, you can utilize the standard Selenium API to interact with elements such as the save button.

[EDIT] In cases where you need to download content from a web server, consider using HttpClient.

To begin, download the page containing the desired link. From there, you can employ different methods to locate the specific link. Depending on the situation, you may need to execute JavaScript or recreate the code in Java to access the correct URL.

After identifying the link, use HttpClient once again to directly download the associated document.

If JavaScript execution is required, tools like Rhino can be instrumental. For scripts that rely on browser objects, consider exploring envjs.
