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'});
