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 to execute the function 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);
}
}will not execute the scheduled task after writing it like this, change it 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);
}
}and succeed, that is, setinterval Then create a new function and execute the methods that need to be executed in it
