我试图在具有不同开始时间的网页上显示两个计时器。在Angular.js中显示多个计时器功能
第一个定时器只显示5秒,然后10秒后我需要显示timer2。 我对Angular非常陌生,并将以下代码放在一起。
它似乎工作正常,除非settimeout被称为第三次它不能正常工作,并且它开始非常快。
控制器
// initialise variables
$scope.tickInterval = 1000; //ms
var min ='';
var sec ='';
$scope.ti = 0;
$scope.startTimer1 = function() {
$scope.ti++;
min = (Math.floor($scope.ti/60)<10)?("0" + Math.floor($scope.ti/60)):(Math.floor($scope.ti/60));
sec = $scope.ti%60<10?("0" + $scope.ti%60):($scope.ti%60);
$scope.timer1 = min + ":" + sec;
mytimeout1 = $timeout($scope.startTimer1, $scope.tickInterval); // reset the timer
}
//start timer 1
$scope.startTimer1();
$scope.$watch('timer1',function(){
if($scope.timer1 !=undefined){
if($scope.timer1 =='00:05'){
$timeout.cancel(mytimeout1);
setInterval(function(){
$scope.startTimer2()
$scope.ti = 0;
},1000)
}
}
})
//start timer 2 after 2 mins and 20 seconds
$scope.startTimer2 = function() {
$scope.ti++;
min = (Math.floor($scope.ti/60)<10)?("0" + Math.floor($scope.ti/60)):(Math.floor($scope.ti/60));
sec = $scope.ti%60<10?("0" + $scope.ti%60):($scope.ti%60);
$scope.timer2 = min + ":" + sec;
mytimeout2 = $timeout($scope.startTimer2, $scope.tickInterval);
}
$scope.$watch('timer2',function(){
if($scope.timer2 !=undefined){
if($scope.timer2 =='00:05'){
$timeout.cancel(mytimeout2);
setInterval(function(){
$scope.startTimer1();
$scope.ti = 0;
},1000)
}
}
})
在我看来,我只是有
<p>{{timer1}}</p>
<p>{{timer2}}</p>
你不应该使用的setInterval但$间隔。 – yeouuu
