PHP multitasking countdown help

Question

I am a novice. I have been working on a post list countdown function recently. I suffer from my lack of talent and lack of skills, so the countdown has not been able to work well. I forgot to give you some advice!

Get back to the topic

I want to get the time when the post was published to start the countdown, countdown End Close Show Post!

Because it is multi-tasking, only one of the referenced countdown codes can take effect, or the countdown can be refreshed and the countdown starts again, which is very distressing! I hope you guys can give me some advice!

Answer 1

Will the countdown be done? This is the countdown of js.

Use php to calculate the remaining seconds. The current time - the publishing timestamp is the remaining seconds. . Then give the remaining seconds to the regcountdown variable

var regcountdown=30;regSendCode= $("#regSendCode");			settime(regSendCode);		function settime(regSendCode) {			//发送验证码倒计时			if(regcountdown == 0){				regSendCode.removeClass('disabled');				regSendCode.attr('onclick','sendemail()');				regSendCode.html("获取验证码");				regcountdown = 30;				return;			}else{				regSendCode.addClass('disabled');				regSendCode.removeAttr('onclick');				regSendCode.html("重新发送("+regcountdown+")");				regcountdown--;			}			setTimeout(function(){				settime(regSendCode);			},1000);		}
