You can make check like this:

您可以像这样进行检查：

console.log( string1.includes(str) && (string1 != str) );

回答by Aakash

var string1 = "orders"
var string2 = "orders/pack"
var string3 = "orders/123"
var str = "/"
console.log(string1.includes(str)); //false 
console.log(string2.includes(str)); //true
console.log(string3.includes(str)); //true

Why are you not using '/' instead of 'orders'? Any boundations which we dont know?

为什么不使用“/”而不是“订单”？有哪些我们不知道的界限？
