javascript - 检查前一个 (-1 & -2) url 是否包含字符串

Question

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

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

这是感谢页面。从订购页面(我检查了 url)，我将用户重定向到/dekuji-vam(这个感谢页面)，因为我必须在条件中使用 -2。

谢谢你的帮助，迈克尔

href 是字符串类型，string.indexOf如果找不到参数，将返回 -1，如果找到，则返回 0 或更高的数字，说明这是它开始的位置，因为你的第二部分 if 语句是 > -2 它将永远是 true

window.location 是当前位置
