是否有一个jquery或js等价于php的$name=$\u get['name']

function getQuerystring(key, default_)
{
  if (default_==null) default_=""; 
  key = key.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regex = new RegExp("[\\?&]"+key+"=([^&#]*)");
  var qs = regex.exec(window.location.href);
  if(qs == null)
    return default_;
  else
    return qs[1];
}

var addtocart = getQuerystring('add_to_cart','false');

This page 有一个良好的运行。您不需要jquery来完成它。他们的jquery版本是:

$.extend({
  getUrlVars: function(){
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
      hash = hashes[i].split('=');
      vars.push(hash[0]);
      vars[hash[0]] = hash[1];
    }
    return vars;
  },
  getUrlVar: function(name){
    return $.getUrlVars()[name];
  }
});

用于:

// Get object of URL parameters
var allVars = $.getUrlVars();

// Getting URL var by its nam
var byName = $.getUrlVar('name');
