Can clearInterval() be called inside setInterval()?
提问by yvonnezoe
bigloop=setInterval(function () {
var checked = $('#status_table tr [id^="monitor_"]:checked');
if (checked.index()===-1 ||checked.length===0 || ){
bigloop=clearInterval(bigloop);
$('#monitor').button('enable');
}else{
(function loop(i) {
//monitor element at index i
monitoring($(checked[i]).parents('tr'));
//delay of 3 seconds
setTimeout(function () {
//when incremented i is less than the number of rows, call loop for next index
if (++i < checked.length) loop(i);
}, 3000);
}(0)); //start with 0
}
}, index*3000); //loop period
I have the code above and sometimes it is working, sometimes it is not. I am wondering if the clearInterval actually clear the timer??because there is this monitorbutton that will only be disabled when it is in monitoringfunction. I have another clearIntervalwhen an element called .outputRemoveis clicked. See the code below:
我有上面的代码，有时有效，有时无效。我想知道clearInterval 是否真的清除了计时器？因为有这个monitor按钮只有在它monitoring起作用时才会被禁用。clearInterval当.outputRemove单击一个被调用的元素时，我还有另一个。请参阅下面的代码：
//remove row entry in the table
$('#status_table').on('click', '.outputRemove', function () {
deleted= true;
bigloop= window.clearInterval(bigloop);
var thistr=$(this).closest('tr');
thistr.remove();
$('#monitor').button('enable');
$('#status_table tbody tr').find('td:first').text(function(index){
return ++index;
});
});
But it was enabled for a while before it is disabled again. Will clearIntervalget the program out from the setIntervalfunction?
但是它在再次禁用之前启用了一段时间。会clearInterval从setInterval函数中取出程序吗？

Yes you can. You can even test it:
是的你可以。你甚至可以测试它：
var i = 0;
var timer = setInterval(function() {
console.log(++i);
if (i === 5) clearInterval(timer);
console.log('post-interval'); //this will still run after clearing
}, 200);In this example, this timer clears when ireaches 5.
在此示例中，此计时器在i达到 5时清除。
