我对Javascript非常陌生,并且不太了解它。但是,我设法创建了一个倒数计时器,半工作就像我想要的那样。它非常简单,但它基本上是一个倒计时到特定日期的计时器,然后一旦达到指定的日期和时间,它就会显示我可以自定义的文本。我希望这个代码能够在倒计时到零时显示带有超链接的按钮。这是我到目前为止的代码:
// Set the date we're counting down to
var countDownDate = new Date(Date.now() + 20000).getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + " days, " + hours + " hours, " +
minutes + " minutes, & " + seconds + " seconds";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "We're Live on Facebook!";
}
}, 1000);
<p id="demo" class="countdown-live" style="text-align:center;"></p>
任何帮助,以显示超链接按钮,而不是文本“我们在Facebook上生活!”我将不胜感激。
只需将HTML添加到您正在设置的字符串中:
// Set the date we're counting down to
var countDownDate = new Date(Date.now() + 20000).getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + " days, " + hours + " hours, " +
minutes + " minutes, & " + seconds + " seconds";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = '<a href="https://facebook.com">We\'re Live on Facebook!</a>';
}
}, 1000);
<p id="demo" class="countdown-live" style="text-align:center;"></p>
在innerHTML()属性中,您可以传递一个HTML标记,如
<a href="...">
<button> YOUR TEXT </button>
</a>
您可以创建一个HTML按钮元素,其中包含指向您尝试指向的页面的链接。确保您为该按钮指定了“演示”ID,以便它与您当前的代码一起使用
<button id="demo" onclick="window.location.href = 'https://www.facebook.com/';">We're live on Facebook!</button>
你需要创建一个这样的按钮:
<button id="myButton" style="display:none"><a href="example.com">Button Text</a></button>
然后你可以通过JavaScript显示它:
document.getElementById("myButton").style.display = "inline";
你可以试试这个:
document.getElementById("demo").innerHTML = "<a href='https://www.youUrl.com'>We're Live on Facebook!</a>";
使用innerHTML属性,您可以添加原始HTML。您还可以添加隐藏标记,然后将其显示为:
可见:
document.getElementById("yourID").style.visibility = "visible";
因为不可见:
document.getElementById("main").style.visibility = "hidden";
我希望这对你有帮助。
在p
之后的html中添加一个按钮和一个dd类来初始隐藏它
<p id="demo" class="countdown-live" style="text-align:center;"></p>
<button id='liveButton' type='button' class='hide'>Your Text</button>
在css中添加类hide
.hide{
display:none;
}
在js当它达到0时删除该类
if (distance < 0) {
clearInterval(x);
document.getElementById("liveButton").classList.remove('hide')
document.getElementById("demo").innerHTML = "We're Live on Facebook!";
}
