JQ取值方法：

jquery本身也不存在取得URL參數的方法，但是已經存在插件，可以直接取得URL等參數
插件連接主頁：https://github.com/allmarkedup/jQuery-URL-Parser

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 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'

最原始的JS方法：

復制代碼 代碼如下:

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];
}

復制代碼 代碼如下:

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;
}

復制代碼 代碼如下:

alert(GetQueryString("參數名1"));

alert(GetQueryString("參數名2"));

alert(GetQueryString("參數名3"));

復制代碼 代碼如下:

<span><Script language="javascript">
function GetRequest() {
var url = location.search; //獲取url中"?"符后的字串
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>

復制代碼 代碼如下:

<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 參數1,參數2,參數3,參數N;
參數1 = Request['參數1'];
參數2 = Request['參數2'];
參數3 = Request['參數3'];
參數N = Request['參數N'];
</Script>
