My scenario is that PDF file download automatically, then user fills it and when click on submit button in PDF it connect to java servlet and save it in DB.
In my Application just the 2nd point is missing. Please provide code how to interact with extension using JavaScript to download file automatically. I just want to download the file.
On the right, go to the Content section, and click on Additional content settings. Click on PDF documents. On the next page, turn on (enable) the Download PDF files instead of automatically opening them in Chrome option. You are done.
Inside the DownloadFile JavaScript function, the URL of the File is passed as parameter to the GET call of the JavaScript XmlHttpRequest call. Then inside the onload event handler, the received Byte Array (Binary Data) is converted to BLOB object and the File is downloaded in Browser. //Set the File URL.
download = 'file. pdf'; link. dispatchEvent(new MouseEvent('click')); } var fileURL = "link/to/pdf"; var fileName = "test. pdf"; download(fileURL,fileName);
To save HTML page as PDF using JavaScript, we can use the html2pdf library. const element = document. getElementById("element-to-print"); const opt = { margin: 1, filename: "myfile.
Use the download attribute.
var link = document.createElement('a'); link.href = url; link.download = 'file.pdf'; link.dispatchEvent(new MouseEvent('click'));
It is also possible to open the pdf link in a new window and let the browser handle the rest:
window.open(pdfUrl, '_blank');
or:
window.open(pdfUrl);
/* Helper function */
function download_file(fileURL, fileName) {
// for non-IE
if (!window.ActiveXObject) {
var save = document.createElement('a');
save.href = fileURL;
save.target = '_blank';
var filename = fileURL.substring(fileURL.lastIndexOf('/')+1);
save.download = fileName || filename;
if ( navigator.userAgent.toLowerCase().match(/(ipad|iphone|safari)/) && navigator.userAgent.search("Chrome") < 0) {
document.location = save.href;
// window event not working here
}else{
var evt = new MouseEvent('click', {
'view': window,
'bubbles': true,
'cancelable': false
});
save.dispatchEvent(evt);
(window.URL || window.webkitURL).revokeObjectURL(save.href);
}
}
// for IE < 11
else if ( !! window.ActiveXObject && document.execCommand) {
var _window = window.open(fileURL, '_blank');
_window.document.close();
_window.document.execCommand('SaveAs', true, fileName || fileURL)
_window.close();
}
}
How to use?
download_file(fileURL, fileName); //call function
