Js+Jq获取URL参数的集中方法示例代码

  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:

  

复制代码 代码如下:

  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];

  }

  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:

  

复制代码 代码如下:

  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;

  }

  这样调用:

  

复制代码 代码如下:

  alert(GetQueryString("参数名1"));

  alert(GetQueryString("参数名2"));

  alert(GetQueryString("参数名3"));

  方法二:

  

复制代码 代码如下:

  <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:

  

复制代码 代码如下:

  <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>
