获取url中的参数

获取url中的参数

方法一：

function getUrlParams (search) {
  search = search || location.search;
 
  // 判断是否为字符串类型
  if (typeof search !== 'string') {
    search = search.toString();
  }
 
  var paramsSplit = search.replace(/^[^\?]*\?/i, '').split(/&/);
  var params = {};
 
  // 数据为空
  if (paramsSplit.length < 1) {
    return params;
  }
 
  if (Array.isArray(paramsSplit)) {
    paramsSplit.forEach(function (item) {
      // 数据为空, 退出方法
      if (!item) {
        return false;
      }
      var itemSplit = item.split(/=/);
 
      // 判断字符串中是否有多个=
      if (itemSplit.length >= 2) { // 是
        var key = itemSplit.splice(0, 1);
        params[key] = itemSplit.join('=');
      }
    });
  }
  return params
}

方法二：

//获取url中参数
    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;
    }

根据key,获取url中的参数

function GetRequest2(key)
    {
        var url = location.search;  
        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]);
            }
        }
        var value = theRequest[key];
        return value;
    }
