在我更改anoini的第一个代码中,gerar()函数显示旧值。
但是,当我删除<div ng-if....
时工作正常。

你不应该为此赋值,而是为gerar函数中的$ scope赋值:
$scope.gerar = function() {
$scope.log = $scope.anoini;
meses = (($scope.anofim - $scope.anoini) * 12) + (12 - $scope.mesini) + $scope.mesfim;
qtdLoop = arrEstacoes.length * meses;
tempoEstimadoMinutos = Math.round((qtdLoop * 20) / 60 );
$scope.log = 'Tempo Estimado: ' + tempoEstimadoMinutos + ' min.' ;
}

始终在ng-model
中使用点!。换句话说,使用对象而不是基元。
ng-if
创建一个子范围,因为您在ng-model
中使用原语,所以您正在失去与此子范围的范围的双向绑定。
var myModel ={
mesini : 1,
anoini : 2011,
mesfim : 7,
anofim : 2015
};
$scope.myModel = myModel;
HTML
<input type="text" ng-model="myModel.mesini">
然后在功能:
$scope.gerar = function() {
$scope.log = myModel.anoini;
var meses = ((myModel.anofim - myModel.anoini)......
.....
}
在使用框架时,了解范围嵌套角度是最重要的事情
