javascritp添加url参数方法，将参数加入到url中,如果原来url中有则覆盖，下面通过代码实例给大家讲解，具体内容请看下文。

js代码如下所示：

function addToUrl(obj){ var aprotocol = location.protocol; var ahost = location.host; var apath = location.pathname; var asearch = location.search; var ahash = location.hash; var result = ''; console.log(obj); var joinObj = function(joinObj_obj){ var result = ''; for(var i in joinObj_obj){ result += i + '=' + joinObj_obj[i]; } return result; }; var splitSearchToObj = function(str){ var resObj = {}; var arr = str.split('&'); for(var i = ; i < arr.length; i++){ resObj[arr[]] = arr[]; } return resObj; }; var existObjKey = function(existObjKey_obj, str){ for(var i in existObjKey_obj){ if(i == str){ return true; } } return false; }; var objExtend = function(obj, obj){ var result = {}; for(var i in obj){ if(existObjKey(obj, i)){ result[i] = obj[i]; }else{ result[i] = obj[i]; } } }; if(asearch == ''){ console.log(obj); result = aprotocol + '//' + ahost + apath + '?' + joinObj(obj) + ahash; }else{ var oldSearchObj = splitSearchToObj(asearch.substr()); result = aprotocol + '//' + ahost + apath + joinObj(objExtend(oldSearchObj, obj)) + ahash; } return result; } addToUrl({'kd': 'aaa'});

JavaScript添加更改URL参数

function ChangeParam(name,value) { var url=window.location.href ; var newUrl="";var reg = new RegExp("(^|)"+ name +"=([^&]*)(|$)");var tmp = name + "=" + value;if(url.match(reg) != null){ newUrl= url.replace(eval(reg),tmp);}else{ if(url.match("[\?]")) { newUrl= url + "&" + tmp; } else { newUrl= url + "?" + tmp; }} location.href=newUrl; }
