使用javascript，由于某种原因，即使 d.getDay() 是 2，我也无法通过该函数输出“星期二”。
<!DOCTYPE html>
<html>
<body>
<p>The getDay() method returns the weekday as a number:</p>
<p id="demo"></p>
<script>
function getDayOfWeek(day){
if (day == 1){
return "Monday";
else if (day == 2){
return "Tuesday";
else{
return "Otherday";
}
}
var d = new Date();
document.getElementById("demo").innerHTML = getDayOfWeek(d.getDay());
</script>
</body>
</html>
最佳答案
看起来您缺少 else 语句中的右大括号。我在下面更新了您的代码片段。
function getDayOfWeek(day){
if (day == 1) {
return "Monday";
} else if (day == 2) {
return "Tuesday";
} else {
return "Otherday";
}
}
var d = new Date();
document.getElementById("demo").innerHTML = getDayOfWeek(d.getDay());
