检查以前的（-1 和 -2）url 是否包含字符串

Question

在我的网络上，我有一个 javascript 来检查最后一个或最后一个 URL 是否包含字符串，但无论我来自哪个 url，每个条件都返回 TRUE。

你能帮我如何正确检查吗？如果我从 ifs 中删除 else，所有条件都变为 TRUE。

这是感谢页面。从订购页面（带有我检查的 url）我将用户重定向到 /dekuji-vam（这个感谢页面），所以我必须在条件下使用 -2。

感谢您的帮助， 迈克尔

href 是字符串类型，string.indexOf 如果找不到参数，则返回 -1，如果找到，则返回数字 0 或更高，说明这是它开始的位置，因为 if 语句的第二部分is > -2 永远是真的

window.location 是当前位置
