javascritp添加url参数将参数加入到url中

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.pathttp://hname;

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'});
