How to compare URL with any number?

Question

I'm trying to compare URL with javascript the current url is:

http://domain/products?save&step&id=287

I used window.location.search, it rendered:

?save&step&id=287

I need to know how to compare URL with any number like this pseudocode, I used (any_number) as example of random number, it doesn't need to match equal number since I had no idea which is properly method.

 var prod_url = window.location.search;

 if(prod_url == "?save&step&id="+(any_number){    
  alert("URL is matched");
 }

I'm open with all suggestions, any method with excepted result is welcome.

Answer 1

要将字符串与正则表达式进行比较，您必须使用match()函数。

匹配＆＃34;任何数字＆＃34;的示例将是：

myString.match(/[0-9]+/); 

Answer 2

您可以使用正则表达式：

所以你的if语句应该是这样的：

if ((/\\?save&step&id=\d/).test(prod_url)) {    
  alert("URL is matched");
}

这应该适用于任何数字。

Answer 3

请试试这个：

var prod_url = "?save&step&id=12345";
if (/\?save\&step\&id=[0-9]+$/.test(prod_url)) {
  alert("URL is matched");
}
