JQuery .inArray() not working
提问by user2962388
Okay, so I am working on a weather application, and I wrote the following test code to verify that the user entered a valid state abbreviation:
好的，所以我正在开发一个天气应用程序，我编写了以下测试代码来验证用户是否输入了有效的状态缩写：
var input = prompt("What state are you in?");
var lower = input.toLowerCase();
var categories = [
"ma",
"ny",
"ct",
"ri",
],
var found = $.inArray(lower, categories);
if (found > -1) {
alert("Cool!");
}
else {
alert("Oh no!");
}
But for some reason, it doesn't work.
但由于某种原因，它不起作用。

Does anyone know why this is? I probably just made a silly mistake, but any help would be greatly appreciated.
有人知道为什么是这样吗？我可能只是犯了一个愚蠢的错误，但任何帮助将不胜感激。

Check your console window in your browser, press F12, there are errors.
在浏览器中检查控制台窗口，按 F12，有错误。
The comma after ] should be a semi-colon:
] 后面的逗号应该是分号：
var input = prompt("What state are you in?");
var lower = input.toLowerCase();
var categories = [
"ma",
"ny",
"ct",
"ri"
];
var found = $.inArray(lower, categories);
if (found > -1) {
alert("Cool!");
}
else {
alert("Oh no!");
}
