Figure 1:

About the countdown function is as Follows:

1  varTime = 10*1000;//calculate the number of milliseconds2     varse;3SE = setinterval (' t_time () ', 1000);4     functiont_time () {5         //Countdown6         varMM = parseint (time/60/1000%60,10);//number of minutes left7         varSS = parseint (time/1000%60,10);//number of seconds remaining8MM =checktime (mm);9SS =checktime (ss);Ten$ ("#timer"). HTML (mm+ ' +ss+ ' seconds '); oneTime = time-1000; a         if(mm==0 && ss==0) { -$ ("#myEnd"). Modal ("toggle")); - clearinterval (se); the         } -     } -  -     functionchecktime (i) { +         if(i<10) { -i = "0" +i; +         } a         returni; at}

In the above code, the Checktime function, the main function is to control the display, for example, the distance time to the end of 8 seconds, the system will be displayed as 08.

Code references in Html:

1  <span class= "label badge-success" > Current time: &nbsp;<span id= "current-time" ></span></span>

The Modal box (mask layer) code is:

1 div id= "myend" class= "modal hide" > 2     <div class= "modal-header" > 3         < Button data-dismiss= "modal" class= "close" type= "button" >x</button> 4         5     </div> 6     <div class= "modal-body" > 7         <p> You have run out of time </p> 8      </div> 9     <div class= "modal-footer" >         <a data-dismiss= "modal" class= "btn btn-success" href= "#" > OK </a>     </div> </div>
