Question

function myFactorial(){

var factorial1 = this.num1*(this.num1-1)*(this.num1-2)*(this.num1-3)*(this.num1-4);

var factorial2 = this.num2*(this.num2-1)*(this.num2-2)*(this.num2-3);
return (factorial1,factorial2);

}

我想显示用逗号分隔的factorial1和factorial2。请帮忙。谢谢！：）

Answer 1

为什么你不能尝试这个：

return factorial1+','+factorial2;

Answer 2

我们不能在return语句中返回两个值。但我们可以实现这样的目标

var factorial = { "factorial1": factorial1, "factorial2": factorial2  };
return factorial;

希望这会对你有所帮助。

Answer 3

做点什么

<input name="username" type="text" class="form-control" placeholder="User ID" autofocus value="<?php echo set_value('username'); ?>" >
<br>
<input name="password" type="password" class="form-control" placeholder="Password"  value = "<?php echo set_value('password'); ?>">

使用return显示多个值
