声明变量后我可以使用tolowercase（）吗？ [英] Can I use tolowercase() after declaring a variable?

问题描述

（文件名为：test.js）

问题在于：

(THE FILE NAME IS: test.js)
Here is the problem:

var Hardware = prompt("What are the physical components of the computer, such as the moniter and system unit, called?");
if (Hardware.toLowercase() == "hardware") {
		var number = 1;

} else { alert("You have failed the test. Please refresh.");     }
if (number == 1) {


}

现在，问题是我每次运行时都会遇到一个typeError，它表示：

Now, the problem is that I get a typeError whenever I run this, which states:

引用：

未捕获TypeError：Hardware.toLowercase不是函数

at test.js：2

Uncaught TypeError: Hardware.toLowercase is not a function
at test.js:2

我尝试了什么：



我试过看看其他人是否有这个同样的问题;我认为没有人。

What I have tried:

I have tried looking to see if others have had this same problem; I don't think anyone has.

推荐答案

它应该是

toLowerCase()

注意区分大小写。

Javascript区分大小写。我修复了你的代码，现在就检查一下。

Hi, Javascript is case sensitive. I've fixed your code, check it now.

var Hardware = prompt("What are the physical components of the computer, such as the moniter and system unit, called?");
alert(Hardware);
if (Hardware.toLowerCase() == "hardware") {
		var number = 1;
 
} else { alert("You have failed the test. Please refresh.");     }
if (number == 1) {
  alert ("Hello I love to be 1")

}
