function triggerDownload(fileUrl, fileName) { // 1. Create a temporary anchor element const link = document.createElement('a'); // 2. Set the target file and the desired filename link.href = fileUrl; link.download = fileName; // 3. (Optional) Some browsers require the link to be in the DOM document.body.appendChild(link); // 4. Programmatically trigger the click event link.click(); // 5. Clean up by removing the element document.body.removeChild(link); } Use code with caution. Generating Files on the Fly (Blobs)
To trigger a download without requiring a user to click a predefined link, you can create a temporary "phantom" anchor element in your code. Basic Implementation
Setting a value for this attribute (e.g., element.download = "report.pdf" ) suggests a default filename for the user's local system.
