环内角$timeout失败

Question

我正在使用角度$timeout作为，

 $scope.alltexts = ["hii" , "hello" , "hehe"]
 var sendtime = 60000
 for (var i = 0; i < $scope.alltexts.length; i++) {
   var text = $scope.alltexts[i]
   $setTimeout(function() {}, (function(){$scope.addtext(text)}, sendtime + (i * 60000)));
 };
 $scope.addtext = function(text){
  console.log(text)
 }

但每过一分钟，它就只能安慰"呵呵"。表示它只考虑最后一个值。请让我知道我应该如何获得正确的结果。

Answer 1

今天closures太多了，你总是在传递最后一个索引......closure将为每个迭代创建一个新scope。

 $scope.alltexts = ["hii" , "hello" , "hehe"]
 var sendtime = 60000
 for (var i = 0; i < $scope.alltexts.length; i++) {
   (function(i){
   var text = $scope.alltexts[i]
   $setTimeout(function() {}, (function(){$scope.addtext(text)}, sendtime + (i * 60000)));
   })(i)
 };
 $scope.addtext = function(text){
  console.log(text)
 }

试试这个

$scope.alltexts = ["hii" , "hello" , "hehe"]
 var sendtime = 60000
 for (var i = 0; i < $scope.alltexts.length; i++) {
   (function(i){
   var text = $scope.alltexts[i]
   $setTimeout(function() {}, (function(){$scope.addtext(text)}, sendtime + (i * 60000)));
   })(i)
 };
 $scope.addtext = function(text){
  console.log(text)
 }
