javascritp添加url参数将参数加入到url中

将对象参数加入到url中，如果原来url中有则覆盖
js代码

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 = 0; i < arr.length; i++）{ resObj[arr[0]] = arr[1]; } return resObj; }; var existObjKey = function（existObjKey_obj, str）{ for（var i in existObjKey_obj）{ if（i == str）{ return true; } } return false; }; var objExtend = function（obj1, obj2）{ var result = {}; for（var i in obj1）{ if（existObjKey（obj2, i））{ result[i] = obj2[i]; }else{ result[i] = obj1[i]; } } }; if（asearch == ""）{ console.log（obj）; result = aprotocol + "//" + ahost + apath + "?" + joinObj（obj） + ahash; }else{ var oldSearchObj = splitSearchToObj（asearch.substr（1））; result = aprotocol + "//" + ahost + apath + joinObj（objExtend（oldSearchObj, obj）） + ahash; } return result; } addToUrl（{"kd": "aaa"}）;
