JS+JQ a centralized method for obtaining URL parameters _javascript Tips for example code

JQ Value Method:

jquery itself does not have the method to get the URL parameters, but there are already plug-ins, you can get the parameters such as URL directly
Plug-in Connection home: Https://github.com/allmarkedup/jQuery-URL-Parser
Download Link: http://download.github.com/allmarkedup-jQuery-URL-Parser-bb2bf37.zip

Examples of Use
Using the current page's URL (for these examples https://mysite.com/information/about/index.html?itemID=2&user= Dave):

Get the Protocol
JQuery.url.attr ("protocol")//returns ' HTTP '

Get the path
JQuery.url.attr ("path")//returns '/information/about/index.html '


Get the Host
JQuery.url.attr ("host")//returns ' Mysite.com '

Get the value for the ItemID query parameter
JQuery.url.param ("ItemID")//returns 2

Get the second segment the URL path
JQuery.url.segment (2)//returns ' about '
Using a different URL to the current page:

Set a different URL and return the anchor string
JQUERY.URL.SETURL ("http://allmarkedup.com/category/javascript/#footer"). attr ("anchor")//Returns ' footer '

JS Native access:

The most original JS method:

Copy Code code as follows:

var urlparams = new Array ();
var aparams = document.location.search.substr (1). Split (' & ');
for (i=0 i < aparams.length; i++) {
var aparam = aparams[i].split (' = ');
Urlparams[aparam[0]] = aparam[1];
}

This call:

Http://127.0.0.1/index.php?name=name1&cid=123
Gets the name parameter passed over
name=urlparams["Name"];

document.write (name);
Get the CID that came in.

cid=urlparams["CID"];

Regular Analysis Method:

Method One:

Copy Code code as follows:

function getquerystring (name) {
var reg = new RegExp ("(^|&)" + name + "= ([^&]*) (&|$)", "I");
var r = window.location.search.substr (1). Match (REG);
if (r!= null) return unescape (r[2]); return null;
}

This call:

Copy Code code as follows:

Alert (getquerystring ("parameter name 1"));

Alert (getquerystring ("parameter Name 2"));

Alert (getquerystring ("parameter name 3"));

Method Two:

Copy Code code as follows:

<span style= "FONT-SIZE:16PX;" ><script language= "JavaScript" >
function Getrequest () {
var url = location.search; Get the "?" in the URL String after the character
var therequest = new Object ();
if (Url.indexof ("?")!=-1) {
var str = URL.SUBSTR (1);
STRs = Str.split ("&");
for (var i = 0; i < strs.length i + +) {
Therequest[strs[i].split ("=") [0]]=unescape (Strs[i].split ("=") [1]);
}
}
return therequest;
}
</Script>

This call:

Copy Code code as follows:

<script language= "JavaScript" >
var Request = new Object ();
Request = Getrequest ();
var parameter 1, Parameter 2, parameter 3, parameter n;
Parameter 1 = request[' parameter 1 '];
Parameter 2 = request[' parameter 2 '];
Parameter 3 = request[' parameter 3 '];
Parameter n = request[' parameter n '];
</Script>
