我的用户组检查
总是返回$.inArray
具体代码位于run函数和checkUserCondition函数中。
如果您运行该程序，它将显示一条带有计数的消息。
单击“Enter Spins”，然后单击“Toggle Numberpad”，然后添加数字8
用户组在组1,2,3,4,5和组5,6,7,8中注册为8
为什么$.inArray()表现那样？

答案 0 :(得分：2)
简短回答_.differenceWith：
因为JavaScript将0视为松散等于false（即0 == false，但是0！== false），要检查数组中是否存在值，您需要检查它是否不等于（或大于）-1。
-1将truthy视为0，将falsy视为array。如果您要查找的号码不在true中，则返回-1视为$(document).ready(function(){
var arr = [1, 2, 3, 4, 5, 6];
var bool = $.inArray(8, arr);
console.log(bool)
if(bool)
console.log('bool is true')
else
console.log('bool is false');
});。
有关JavaScript中boolean的更多信息，请参阅以下链接：(from jQuery documentation)和w3school
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>\n
答案 1 :(得分：1)
如果数组中存在某些内容，则返回其索引，否则返回-1
if($.inArray(object, array) != -1){
// In array
} else {
// Not in array
}
