JQ value method:

Jquery itself does not exist to get URL parameters, but there is a plug-in, you can directly get URL and other parameters Plug-in connection home page: https://github.com/allmarkedup/jQuery-URL-Parser Download link: http://download.github.com/allmarkedup-jQuery-URL-Parser-bb2bf37.zip

Examples of the use Using the current page ‘s url (for these examples at 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 from 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 primitive JS method:

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];
}

Call:

http://127.0.0.1/index.php? Name = name1 & cid = 123 // gets the passed name parameter Name = URLParams (” name ”),

Document. The write (name); // get the transmitted cid

Cid = URLParams (” cid ”);

Regular analysis:

Method one:

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;
}

Call:

alert(GetQueryString(" Parameter names 1"));

alert(GetQueryString(" Parameter names 2"));

alert(GetQueryString(" Parameter names 3"));

Method 2:

<span style="font-size: 16px;"><Script language="javascript">
function GetRequest() {
var url = location.search; //Get the "?" in the url String after a string
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>

Call:

<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>
