One-time timer is executed

1     //One-time timer is executed2 3SetInterval (Console.log (1), 1000);//performed 1 times4 5 //------------------------------------6 7     varA =function(){8Console.log (1);9     };Ten  OneSetInterval (A (), 1000);//performed 1 times A  - //------------------------------------ -  theSetTimeout (Console.log (1), 1000);//performed 1 times

One time delay timer

1 // one time delay timer 2     var a = 0; 3     var b = setTimeout (function() {4         a++; 5         Console.log (a);                             // assignment interval wait time execution 6     },1000);

multiple timer and clearinterval removal timer

1 //multiple executions and clearinterval removal timers2     varA = 0;3     varb = SetInterval (function(){4a++;5 Console.log (a);6         if(A = = 5) {clearinterval (b)}//clearinterval7},1000);//executes multiple times

SetInterval syntax

SetInterval (function,interval[,arg1,arg2,...... argn])

1     function Show (str) {                             //arguments2        console.log (str)3      }45     setinterval (show,1000,111);                     // arguments

SetInterval (object,methodname,interval[,arg1,arg2,..... argn]) ★ This to be continued

In addition before in Xin Space See, Requestanimationframe (), Sensory method class is, this also to be continued 、-。 *

Finally share a time-out code, write not meticulous, just provide ideas, have small partners to improve hope can also share to me

1 // Countdown 2     var num = ten; 3     var settime = setinterval (function() {4         num--; 5         console.log (num); 6         if (num = = 0 ) clearinterval (settime); 7     },1000)
