使倒计时计时器显示模态窗口引导程序

Question

我还有一个问题。这次我想让它在倒数计时器达到 0 时触发或显示模式窗口以显示。

我有模态和倒数计时器的代码，但我不知道它是如何制作的，所以它需要模态。

我已经尝试了几个我读过的建议，但没有一个可行，或者它只是把代码搞砸了。

非常感谢。

var seconds = 300; //**change 120 for any number you want, it's the seconds **//
function secondPassed() {
    var minutes = Math.round((seconds - 30)/60);
    var remainingSeconds = seconds % 60;
    if (remainingSeconds < 10) {
        remainingSeconds = "0" + remainingSeconds;  
    }
    document.getElementById('countdown').innerHTML = minutes + ":" + remainingSeconds;
    if (seconds == 0) {
        clearInterval(countdownTimer);
        document.getElementById('countdown').innerHTML = "Last chance!";
    } else {
        seconds--;
    }
}
 
var countdownTimer = setInterval('secondPassed()', 1000);

<!-- Modal start-->

随便用

$('#ventanamdl').modal('show');

为了你的目的

var seconds = 300; //**change 120 for any number you want, it's the seconds **//
function secondPassed() {
    var minutes = Math.round((seconds - 30)/60);
    var remainingSeconds = seconds % 60;
    if (remainingSeconds < 10) {
        remainingSeconds = "0" + remainingSeconds;  
    }
    document.getElementById('countdown').innerHTML = minutes + ":" + remainingSeconds;
    if (seconds == 0) {
        clearInterval(countdownTimer);
        document.getElementById('countdown').innerHTML = "Last chance!";
        $('#ventanamdl').modal('show');
    } else {
        seconds--;
    }
}

//now your setInterval call is ok
var countdownTimer = setInterval(secondPassed, 1000);

您的 setInterval 调用不正常。

确保您的引导 CSS 和 JS 以及 jQuery 已正确加载。
