simple jquery second counter
提问by Kevin Brown
What is the simplest way to increase a variable by 1 every second?
每秒将变量增加 1 的最简单方法是什么？
回答by g.d.d.c
var counter = 0;
setInterval(function () {
++counter;
}, 1000);
Additionally, if you ever need to turn it off again, this makes that possible:
此外，如果您需要再次将其关闭，则可以这样做：
var counter = 0;
var myInterval = setInterval(function () {
++counter;
}, 1000);
// to stop the counter
clearInterval(myInterval);
回答by Gert Grenander
The simplest way is setInterval("x++",1000);, where x++can be replaced with your increment. Example:
最简单的方法是setInterval("x++",1000);， wherex++可以用你的增量替换。例子：
JavaScript/jQuery
JavaScript/jQuery
var x=0;
setInterval("x++",1000); // Increment value every second
// Let's just add a function so that you can get the value
$(document).ready(function () {
$("#showval").click(function(){
alert(x);
});
});

a better way is via closed function:
更好的方法是通过封闭函数：
function setIntervalTimes(i_func, i_sleep, i_timesRun){
var timesRun = 0;
var interval = setInterval(function(){
timesRun += 1;
if(timesRun === i_timesRun){
clearInterval(interval);
}
i_func();
}, i_sleep);
},

用
$(document).ready(function() {
timer(8, 'time1'); // seconds and element
timer(3605, 'time2'); // seconds and element
});
first: <span>Counting "8" seconds</span>
<span id="time1">--:--</span>
second: Counting "3605" seconds --:--
秒：计算“3605”秒--：--
