js timer

js can use two timers, one is setInterval (function(){}, time); the other is setTimeout (function(){}, time);

The difference between the two is that setInterval is not set after time milliseconds. Execute a function once, settimeout is executed after time milliseconds,

I encountered a problem here,

Js code

function startFlushTime(min){

var sec = min*60;

var time = timeFormat( sec);

$("#time").html(time);

setInterval(doflush(), 1000);

}

function doflush(){

debugger

var time = $(" #time").html();

if(time && time!=''){

var res = timeFormat(timeParse(time)-1)

$("#time").html(res) ;

}

}

After writing this way, the scheduled task will not be executed and modified to

Js code

function startFlushTime(min){

var sec = min*60;

var time = timeFormat(sec);

$("#time").html(time);

setInterval(function(){doflush();}, 1000);

}

function doflush(){

debugger

var time = $("#time").html();

if(time && time!=''){

var res = timeFormat(timeParse(time)-1)

$("#time").html (res);

}

}

After success, that is, create a new function after setinterval and execute the method that needs to be executed in it
