I have a download link on my page which works just fine but it doesn\'t refresh/redirects my page. Here\'s my code.

@RequestMapping(method = RequestMethod.PO         


        

Answer 1

I used the following structure to solve my problem. The function submit the form and back, in other words, you download the file and refresh the previous link. Using this solution, you can even show and hide messages errors with some template render, in my case, I used Thymeleaf.

To make the code more readable, I removed the Thymeleaf tags.

JS file:

function submitAndBack(formId) {
    let formDoc = document.getElementById(formId);
    formDoc.submit();
    sleep(1000).then(function() {
        window.history.back();
    });
}

function sleep(milliseconds) {
    return new Promise(function (resolve) {
        setTimeout(resolve, milliseconds);
    });
}

HTML form:

      Some info
      
      
          Submit
