JavaScript 如果提示密码为真则下载文件

Question

I want to download a file if user enters the correct password

I have a button in my html file:

<button onclick="password()"><h3>Code</h3> </a>

in my.js file, here is the function:

function password() {
    var password = prompt("Please enter the password");
    if (password === "password") {
        //download the file
    }
    else {
        alert("Password incorrect");
    }
}

the file to be downloaded is located at "../file/file.txt"

I am unsure how to download the file once user enters the correct file

Answer 1

Try this.

<a id="download" style="display: none" 
    href="../file/file.text" 
    download>Download</a>


function password() {
    var password = prompt("Please enter the password");
    if (password === "password") {
        document.getElementById('download').click();
    }
    else {
        alert("Password incorrect");
    }
}
