JS get URL path includes regular match rule to get

General Get methods:

var protocol = Window.location.protocol; "http:"

var host = Window.location.host; "localhost" or "www.baidu.com"

var pathname = Window.location.pathname; "/dkrl/services/cases.php"

var href = window.location.href; "Http://localhost/dkrl/services/cases.php?noId=7"

var search = Window.location.search; "? noid=7"

Use JS to get the current page name

var strurl = window.location.href;

var arrurl = Strurl.split ("/");

var strpage = arrurl[arrurl.length-1];

var indexof = Strpage.indexof ("?");

if (indexof! =-1) {

Strpage = Strpage.substr (0,strpage.indexof ("?"));

}

alert (strpage);

Regular Fetch method:

Match any character (. *)

The substitution of JS strings and the use of the Replace () method

The Replace (Regexp,replacement) method has two parameters, the first parameter can be a plain text string or a RegExp object, see the use of RegExp object, the second parameter is a string can also be a function.

The following is an example of JS string substitution:

Example 1:

var str= "Hello world!";

document.write (Str.replace (/world/, "Phper"));

Example 2:

var reg=new RegExp ("(\\w+), (\\d+), (\\w+)", "GMI");

var info= "Lili,14,china";

var rep=info.replace (Reg, "She is $ $, $ years old, come from $");

Alert (rep);
