JQuery Detect If in Homepage and Homepage PLUS url Variables
提问by Satch3000
I am using this code to detect the homepage and it works great:
我正在使用此代码来检测主页，并且效果很好：
var url= window.location.href;
if(url.split("/").length>3){
alert('You are in the homepage');
}
My problem is that I also need to detect if the url has variables for example:
我的问题是我还需要检测 url 是否有变量，例如：
mysite.com?variable=something
I need to also detect if the url has variables on it too
我还需要检测 url 上是否也有变量

Take a look at the window.location docs, the information you want is in location.search, so a function to check it could just be:
看看window.location docs，你想要的信息在location.search，所以检查它的函数可能只是：
function url_has_vars() {
return location.search != "";
}

Using window.location.pathnamecould work too:
使用window.location.pathname也可以：
if ( window.location.pathname == '/' ){
// Index (home) page
} else {
// Other page
console.log(window.location.pathname);
}

You can find out if you're on the homepage by comparing href to origin:
您可以通过将 href 与 origin 进行比较来确定您是否在主页上：
window.location.origin == window.location.href
To get the query parameters you can use the answer here: How can I get query string values in JavaScript?
要获取查询参数，您可以使用此处的答案： 如何在 JavaScript 中获取查询字符串值？
回答by Sudip Pal
You need a query string searching function to do this..
您需要一个查询字符串搜索功能来执行此操作。
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
Before redirect check the query string and match with the expected value and redirect as requirement.
在重定向之前检查查询字符串并与预期值匹配并根据要求重定向。

if current url is xxxxx.com something like that, then xxx
如果当前 url 是 xxxxx.com 之类的，那么 xxx
if (window.location.href.split('/').pop() === "") {
//this is home page
}
