JQ取值方法:
jquery本身也不存在取得URL参数的方法,但是已经存在插件,可以直接取得URL等参数
插件连接主页:https://github.com/allmarkedup/jQuery-URL-Parser
下载链接: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 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原生获取:
最原始的JS方法:
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];
}
这样调用:
http://127.0.0.1/index.php?name=name1&cid=123
//取得传过来的name参数
name=URLParams["name"];
document.write(name);
//取得传过来的cid
cid=URLParams["cid"];
正则分析法:
方法一:
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;
}
这样调用:
alert(GetQueryString("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));
方法二:
<span style="font-size: 16px;"><Script language="javascript">
function GetRequest() {
var url = location.search; //获取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>
这样调用:
<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 参数1,参数2,参数3,参数N;
参数1 = Request['参数1'];
参数2 = Request['参数2'];
参数3 = Request['参数3'];
参数N = Request['参数N'];
</Script>
