I'm making signup form stuff and I want to save data to server and I got this code :
function Signup()
{
var text = "hello world",
blob = new Blob([text], { type: 'text/plain' }),
anchor = document.createElement('a');
anchor.download = "hello.txt";
anchor
anchor.href = (window.webkitURL || window.URL).createObjectURL(blob);
anchor.dataset.downloadurl = ['text/plain', anchor.download, anchor.href].join(':');
anchor.click();
}
But its download file and I'm wondering how to save/download it to server.
CodePudding user response:
You can't.
The code you have found is for triggering a download and saving a file to the browser's download directory (client-side).
It would be a serious security risk for a web browser to be able to write to arbitrary files on the server.
Instead, create a web service (using the server side programming language of your choice) and make an HTTP request to it (e.g. by submitting a form or using fetch
).
Note that for a sign up system, you are almost certainly going to want to save the data to a database and not to a file (that is still a matter for server-side code though).
