动态更改导航栏文本

Question

我正在为iOS和Android开发一个混合应用程序，我想在其中展示一天。 如果您在星期二打开应用程序，它将显示星期二，依此类推。 它是西班牙语的，所以说“Miércoles”的是星期三，但是我手动编写了它，所以我想更改它，所以如果今天是星期三，它会自动更改。

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;

它不起作用，没有控制台错误或警告。

Answer 1

您多次声明相同的变量，因此将忽略第一个之后的声明。

像这样使用一个工作日数组看起来会更好：

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 2

看来您有错字。

从

$scrope.variable = hoy;

至

$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;
