如何在頁面底部顯示彈出模型？

Question

我有一個popup模式，顯示10秒後。但它顯示在頁面的頂部，我希望它應該顯示在頁腳底部的底部。

我該怎麼做？

這裏是我的代碼：

// Get the modal 
 
    var modal = document.getElementById('myModal'); 
 
    // Get the button that opens the modal 
 
    var btn = document.getElementById("myBtn"); 
 
    // Get the <span> element that closes the modal 
 
    var span = document.getElementsByClassName("close2")[0]; 
 
    // When the user clicks the button, open the modal 
 
    btn.onclick = function() { 
 
     modal.style.display = "block"; 
 
    } 
 
    // When the user clicks on <span> (x), close the modal 
 
    span.onclick = function() { 
 
     modal.style.display = "none"; 
 
    } 
 
    // When the user clicks anywhere outside of the modal, close it 
 
    window.onclick = function(event) { 
 
     if (event.target == modal) { 
 
      modal.style.display = "none"; 
 
     } 
 
    }

.close { 
 
    color: white; 
 
    float: right; 
 
    font-size: 28px; 
 
    font-weight: bold; 
 
} 
 
.close:hover, 
 
.close:focus { 
 
    color: #000; 
 
    text-decoration: none; 
 
    cursor: pointer; 
 
} 
 
.modal-header { 
 
    padding: 2px 16px; 
 
    background-color: #2098d1; 
 
    color: white; 
 
} 
 
.modal-body { 
 
    padding: 2px 16px; 
 
} 
 
.modal-footer { 
 
    padding: 2px 16px; 
 
    background-color: #5cb85c; 
 
    color: white; 
 
} 
 
.modal { 
 
    position: absolute; 
 
    top: 200px; 
 
    right: 50px; 
 
    bottom: 0; 
 
    left: 0; 
 
    z-index: 1040; 
 
    overflow: auto; 
 
    overflow-y: auto; 
 
}

不知道，如果你需要這麼多代碼。但是，這可以進行這樣：

的JavaScript：

$(function() { 
    setTimeout(function() { 
    $("#popup").modal(); 
    }, 2000); 
}); 

CSS：

#popup { 
    top: auto; 
    bottom: 10px; 
    outline: none; 
}
