我有一個大約需要50秒才能加載的php頁面。那段時間我想讓Bootstrap進度條運行。但是這隻在頁面加載後才運行。無法在頁面加載前運行Bootstrap進度條
這裏是我的代碼:

<script>
$(document).ready(function(){
var progressBar = $('.progress-bar');
var percentVal = 0;
window.setInterval(function(){
percentVal += 2;
progressBar.css("width", percentVal+ '%').attr("aria-valuenow", percentVal+ '%').text(percentVal+ '%');
if (percentVal == 100)
{
var link = document.getElementById('nav-ask');
link.style.display = 'none'
}
}, 500); })
</script>
</head>

這裏是link到PHP頁面。關於如何在頁面加載之前運行進度欄的任何想法?目前它在頁面完全加載後加載。我希望在用戶在瀏覽器中輸入URL時立即執行此操作。
試過在window.load函數中運行進度條嗎? – Akintunde007
你必須顯示帶有沒有報告的進度條的頁面,然後從另一個使用Ajax的JavaScript頁面獲取報告。 – Jarzon
@freginold我認爲你錯誤地刪除了一些代碼。 – Jarzon
