How to check if URL has a specific string at the end
提问by Alessandro
I need to get an overlay to slide down based on what the URL has at the end of it.
我需要根据 URL 末尾的内容让覆盖层向下滑动。
If (URL has 'faq' at the end) { overlay comes down }
如果（URL 末尾有 'faq'）{ 覆盖下降}
How can you do that in jQuery/JavaScript?

If your URL looks something like this http://yourdomain.com/faq, you could do something like this:
如果您的 URL 看起来像这样http://yourdomain.com/faq，您可以执行以下操作：
var url = window.location.href;
var lastPart = url.substr(url.lastIndexOf('/') + 1);
if (lastPart === "faq") {
// Show your overlay
}
This would make it possible to check for other endings and act on them as well.
这将使检查其他结局并对其采取行动成为可能。
Update:
更新：
To get it working, even if the URL has a trailing slash, you could create a function like this:
为了让它工作，即使 URL 有一个斜杠，你也可以创建一个这样的函数：
function getLastPart(url) {
var parts = url.split("/");
return (url.lastIndexOf('/') !== url.length - 1
? parts[parts.length - 1]
: parts[parts.length - 2]);
}
You could then call the function like getLastPart(window.location.href)to get the last part of the URL for the current page.
然后您可以调用该函数getLastPart(window.location.href)来获取当前页面的 URL 的最后一部分。
Here is a working example as well: http://jsfiddle.net/WuXHG/
这里也是一个工作示例：http: //jsfiddle.net/WuXHG/
Disclaimer: If your URLs use hashes at the end, or a querystring, you would have to strip the from the URL first, for this script to work properly
免责声明：如果您的网址在末尾使用哈希值或查询字符串，则您必须先从网址中删除 ，以便此脚本正常工作

You should be able to use the window.location object for this with a regexp, something like this:
您应该能够通过正则表达式使用 window.location 对象，如下所示：
/faq$/.test(window.location)

A new method endsWith()has been added to the ES6 specification. For previous versions we can polyfill it using
endsWith()ES6 规范中添加了一个新方法。对于以前的版本，我们可以使用 polyfill 它
if (!String.prototype.endsWith)
String.prototype.endsWith = function(searchStr, Position) {
// This works much better than >= because
// it compensates for NaN:
if (!(Position < this.length))
Position = this.length;
else
Position |= 0; // round position
return this.substr(Position - searchStr.length,
searchStr.length) === searchStr;
};
Now you can easily write
现在您可以轻松编写
If (window.location.href.endsWith("faq")) {
// Show your overlay
}

You can get the current URL using :
您可以使用以下方法获取当前 URL：
var currentUrl = window.location.href;
Then you can use indexOf to check if your token is in the end of string (here faq)
然后你可以使用 indexOf 来检查你的令牌是否在字符串的末尾（这里是 faq）
if (currentUrl.indexOf('faq') == currentUrl.length - 3)
{
// Do something here
}
