动态更改导航栏文本

Question

我正在为 iOS 和 Android 构建一个混合应用程序，并且有一个部分我想显示一天。如果您在星期二打开应用程序，它会显示星期二，依此类推。它是西班牙语的，所以，它说 "Miércoles" 今天是星期三，但我手动写的，我希望它改变所以如果今天是星期三，它会自动改变。

我尝试使用 ng-bind 和以下代码更改它：

    var today = new Date();
  if(today.getDay() == 0){
    var hoy = "Domingo";
  } else if(today.getDay() == 1){
    var hoy = "Lunes";
  }else if(today.getDay() == 2){
    var hoy = "Martes";
  }else if(today.getDay() == 3){
    var hoy = "Miercoles";
  }else if(today.getDay() == 4){
    var hoy = "Jueves";
  }else if(today.getDay() == 5){
    var hoy = "Viernes";
  }else if(today.getDay() == 6){
    var hoy = "Sábado";
  }
  $scrope.variable = hoy;

没有成功，没有控制台错误或警告。

Answer 1

看来你打错了。

变化自

$scrope.variable = hoy;

至

$scope.variable = hoy;

Answer 2

您多次声明同一个变量，因此第一个之后的声明将被忽略。

像这样使用工作日数组会更好看：

var now = new Date();
//var weekday = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
var weekday = ["Domingo", "Lunes", "Martes", "Miercoles", "Jueves", "Viernes","Sábado"];

var hoy = weekday[now.getDay()];
$scope.variable = hoy;

Answer 3

只需更新您的代码，

var today = new Date(),
    weekday = [ 
                "Domingo",
                "Lunes",
                "Martes",
                "Miercoles",
                "Jueves",
                "Viernes",
                "Sábado"
              ];

var hoy = weekday[today.getDay()];
$scope.variable = hoy;
