提问by RayLoveless
How could I do something like this:
我怎么能做这样的事情：

if(window.location.contains("franky")) // This doesn't work, any suggestions?
{
alert("your url contains the name franky");
}
});
</script>

You need add href property and check indexOfinstead of contains
您需要添加 href 属性并检查indexOf而不是contains
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
if (window.location.href.indexOf("franky") > -1) {
alert("your url contains the name franky");
}
});
</script>回答by NickFitz
if (window.location.href.indexOf("franky") != -1)
would do it. Alternatively, you could use a regexp:
会做的。或者，您可以使用正则表达式：
if (/franky/.test(window.location.href))

window.locationisn't a String, but it has a toString()method. So you can do it like this:
window.location不是字符串，但它有一个toString()方法。所以你可以这样做：
(''+window.location).includes("franky")
or
或者
window.location.toString().includes("franky")
From the old Mozilla docs:
Location objects have a toString method returning the current URL. You can also assign a string to window.location. This means that you can work with window.location as if it were a string in most cases. Sometimes, for example when you need to call a String method on it, you have to explicitly call toString.
Location 对象有一个返回当前 URL 的 toString 方法。您还可以为 window.location 分配一个字符串。这意味着在大多数情况下，您可以将 window.location 当作字符串使用。有时，例如当您需要对其调用 String 方法时，您必须显式调用 toString。

The regex way:
正则表达式方式：
var matches = !!location.href.match(/franky/); //a boolean value now
Or in a simple statement you could use:
或者在一个简单的语句中，您可以使用：
if (location.href.match(/franky/)) {
I use this to test whether the website is running locally or on a server:
我用它来测试网站是在本地运行还是在服务器上运行：
location.href.match(/(192.168|localhost).*:1337/)
This checks whether the hrefcontains either 192.168or localhostAND is followed by :1337.
这将检查href是否包含192.168或localhostAND 后跟:1337。
As you can see, using regex has its advantages over the other solutions when the condition gets a bit trickier.
如您所见，当条件变得有点棘手时，使用正则表达式比其他解决方案更具优势。

document.URLshould get you the URLand
document.URL应该让你URL和
if(document.URL.indexOf("searchtext") != -1) {
//found
} else {
//nope
}

Try this, it's shorter and works exactly as window.location.href:
试试这个，它更短，工作原理完全相同window.location.href：
if (document.URL.indexOf("franky") > -1) { ... }
also if you want to check the previous URL:
如果您想检查以前的 URL：
if (document.referrer.indexOf("franky") > -1) { ... }

Easier it gets
更容易获得
<script type="text/javascript">
$(document).ready(function () {
var url = window.location.href;
if(url.includes('franky')) //includes() method determines whether a string contains specified string.
{
alert("url contains franky");
}
});
</script>

Try this:
尝试这个：
<script type="text/javascript">
$(document).ready
(
function ()
{
var regExp = /franky/g;
var testString = "something.com/frankyssssddsdfjsdflk?franky";//Inyour case it would be window.location;
if(regExp.test(testString)) // This doesn't work, any suggestions.
{
alert("your url contains the name franky");
}
}
);
</script>
