单击按钮时下载文件jQuery

Question

I have the following button in my HTML:

<button id="exportVCardButton">Export vCard</button>

I have the following jQuery code that executes when the button is clicked:

$(document).on('click', '#exportVCardButton', function (e) {
    e.preventDefault();
    document.location.href = 'contacts/createVCard.php?contactID=<?php echo $contactID; ?>';
});

When this button is clicked, the createVCard.php script creates a vCard and sends the file as a download to the browser. In Safari, it works just fine. However, in Google Chrome, I am getting the following error in the console:

Resource interpreted as Document but transferred with MIME type text/x-vcard

I have tried several different solutions but none seem to work. Does anybody have any suggestions to make the file download in Chrome as it does in Safari?

Answer 1

The only way I know around this issue with chrome is to specify the HTML5 download attribute inside an <a> tag, to use this your code would change to:

<a id="exportVCardButton" href="contacts/createVCard.php?contactID=<?php echo $contactID; ?>" download>Export vCard</a>

Or, with JQuery, perhaps something like: (Untested)

$(document).on('click', '#exportVCardButton', function (e) {
    e.preventDefault();
    var href = $('#exportVCardButton').attr('href');
    document.location.href = href;
});

You would need to make sure you have the href attribute set in your link for the jQuery to work
