问题描述
我需要帮助javascript中的倒数计时器。我在PHPJabbers中找到了以下代码。这段代码工作正常,但是当我重新加载页面时,时间会回到初始时间。即使我加载页面,我也想保留时间。如果秒== 0我还想在里面添加PHP函数。我不确定它是否可行。提前致谢
I need help with countdown timer in javascript.I found the code below in PHPJabbers. This code works fine, but when I reload the page the time goes back to its initial time. I want to retain the time even if I load the page. I want also to add PHP function inside if seconds == 0. I'm not sure if it's possible. Thanks in advance
<span id="countdown" class="timer"></span>
<script>
var seconds = 60;
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 = "Buzz Buzz";
} else {
seconds--;
}
}
var countdownTimer = setInterval('secondPassed()', 1000);
</script>
推荐答案
检查一下,(使用cookies实现)
Check this, (implemented using cookies)
function setCookie(cname,cvalue,exdays)
{
var d = new Date();
d.setTime(d.getTime()+(exdays*24*60*60*1000));
var expires = "expires="+d.toGMTString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
function getCookie(cname)
{
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++)
{
var c = ca[i].trim();
if (c.indexOf(name)==0) return c.substring(name.length,c.length);
}
return "";
}
//check existing cookie
cook=getCookie("my_cookie");
if(cook==""){
//cookie not found, so set seconds=60
var seconds = 60;
}else{
seconds = cook;
console.log(cook);
}
function secondPassed() {
var minutes = Math.round((seconds - 30)/60);
var remainingSeconds = seconds % 60;
if (remainingSeconds < 10) {
remainingSeconds = "0" + remainingSeconds;
}
//store seconds to cookie
setCookie("my_cookie",seconds,5); //here 5 is expiry days
document.getElementById('countdown').innerHTML = minutes + ":" + remainingSeconds;
if (seconds == 0) {
clearInterval(countdownTimer);
document.getElementById('countdown').innerHTML = "Buzz Buzz";
} else {
seconds--;
}
}
var countdownTimer = setInterval(secondPassed, 1000);
