PHP+JS ใช้ฟังก์ชันการนับถอยหลัง

JS 部分

复制代码代码如下:

setInterval ("time_controller ()", 1,000);

ฟังก์ชั่น time_controller () {

$ (". time_val") แต่ละ (ฟังก์ชั่น () {

var time_id = "time_show _"+$ (นี่) .attr ('for');

var time_val = $ (นี่) .attr ('ค่า');

$ (นี่) .attr ('ค่า', time_val-1);

show_time (time_id, time_val*1000);

-

-

ฟังก์ชั่น show_time (id, timestamp)

-

var timer = document.getElementById (id);

var str_time, int_day, int_hour, int_minute, int_second;

var time_distance = timestamp;

ถ้า (time_distance> 0)

-

int_day = math.floor (time_distance/86400000)

time_distance- = int_day*86400000;

int_hour = math.floor (time_distance/3600000)

time_distance- = int_hour*3600000;

int_minute = math.floor (time_distance/60000)

time_distance- = int_minute*60000;

int_second = math.floor (time_distance/1000)

ถ้า (int_hour <10)

int_hour = "0"+int_hour;

ถ้า (int_minute <10)

int_minute = "0"+int_minute;

ถ้า (int_second <10)

int_second = "0"+int_second;

str_time = "<b> 剩余时间："+int_day+"天"+int_hour+"小时"+int_minute+"分钟"+int_second+"秒 </b>";

timer.innerhtml = str_time;

}อื่น{

timer.innerhtml = "<b> 剩余时间： 0 天 0 小时 0 分钟 0 秒 </b>";

html 部分， php 和 js 的时间倒计时

复制代码代码如下:

<div id = "time_show _ {$ list.cmd_id}"> </div>

<input type = "hidden" for = "{$ list.cmd_id}" value = "{$ list.time_val}" />
