这个类的主要目的是为了方便平时编码中的Url类型的数据操作
全局名称
全局名称是由源码的最后一行代码确定的,默认为Url,如存在相同名称的对象会抛出异常;
可以通过 requirejs的define
获取
(function (window, name) {
if (name in window) {
throw new Error(["already '", name, "' in 'window'"].join(""));
}
...
window[name] = Url;
if (typeof window.define === "function") {
window.define(name, [], function () { return Url; });
}
})(window, "Url");
静态方法
Url.encoded(params)
将对象编码为URL参数,类似于jQuery.param()
,不包含“?”;
var myObject = {
a: {
one: 1,
two: 2,
three: 3
},
b: [1,2,3]
};
var recursiveEncoded = Url.encoded(myObject);
var recursiveDecoded = decodeURIComponent(recursiveEncoded);
console.log(recursiveEncoded);
console.log(recursiveDecoded);
结果:
a%5Bone%5D=1&a%5Btwo%5D=2&a%5Bthree%5D=3&b%5B%5D=1&b%5B1%5D=2&b%5B2%5D=3
a[one]=1&a[two]=2&a[three]=3&b[]=1&b[1]=2&b[2]=3
Url.parseSearch(search)
与Url.encoded(params)
相反,将URL参数字符串转为js对象
var myObject = {
a: {
one: 1,
two: 2,
three: 3
},
b: [1,2,3]
};
var recursiveEncoded = Url.encoded(myObject);
var obj = Url.parseSearch(recursiveEncoded);
console.log(JSON.stringify(obj, null, " "));
结果:(从URL参数转为js对象会丢失参数类型,全部变为string)
{
"a": {
"one": "1",
"two": "2",
"three": "3"
},
"b": [
"1",
"2",
"3"
]
}
Url.combine(url1, url2)
将2个url组合成一个新的Url
Url.combine("/","/api/user/get").toString(); // /api/user/get
Url.combine("/http/web","/api/user/get").toString(); // /api/user/get
Url.combine("/http/web","api/user/get").toString(); // /api/user/get
Url.combine("/http/web/","api/user/get").toString(); // /http/api/user/get
Url.combine("/http/web/","../api/user/get").toString(); // /http/api/user/get
Url.combine("/http/web","../api/user/get").toString(); // /api/user/get
Url.combine("/http/web","./api/user/get").toString(); // /http/web/api/user/get
带参数的情况下,默认url2的参数覆盖url1的参数;
如果希望保留url1的参数可以将url2的参数写做ur2="path?&name=value"
,在?
与name间插入一个&
符号;
如果url2与url1参数相同会将参数改为数组;
Url.combine("/http/web?id=1","api/user").toString(); // //http/api/user
Url.combine("/http/web?id=1","?name=2").toString(); // /http/web?name=2
Url.combine("/http/web?id=1","?&name=2").toString(); // /http/web?id=1&name=2
Url.combine("/http/web?id=1","?&id=2").toString(); // /http/web?id%5B%5D=1&id%5B1%5D=2
Url.combine("/http/web?id=1","./../?id=2").toString(); // /http/?id=2
Url.combine("/http/web?id=1","./../?&name=2").toString(); // "/http/?id=1&name=2"
url2不存在锚记时,保留url1的锚记,否则url2的锚记覆盖url1的锚记;
url2结尾为#
号时,直接清除url1的所有锚记
Url.combine("/http/web?id=1#h1","api/user").toString(); ///http/api/user#h1
Url.combine("/http/web?id=1#h1","./../?&name=2#h2").toString(); // /http/?id=1&name=2#h2
Url.combine("/http/web?id=1#h1","api/user#").toString(); // /http/api/user?id=1
也可以传多个参数
function combine(url1, url2) {
... ...
}
Url.combine = function (url1, url2) {
if (arguments.length < 2) {
return arguments[0];
}
var _base = url1;
for (var i = 1; i < arguments.length; i++) {
_base = combine(_base, arguments[i]).toString();
}
return _base;
};
实例化
无论是否通过new
关键字调用都会返回一个实例;
不提供url
参数时,取window.location.href
的值;
var token = new Object();
function Url(url) {
if (arguments[1] !== token) {
return new Url(url, token);
}
url = trim(url || window.location.href);
... ...
}
实例属性
scheme
url协议类型,如http://
,https://
也可以是//
var url = new Url("http://baidu.com");
console.log(url.scheme); // http://
url.scheme = "https://"
console.log(url.toString()); // https://baidu.com
domain
url的域名部分
var url = new Url("http://baidu.com/api/");
console.log(url.domain); // baidu.com
url.domain= "google.com"
console.log(url.toString()); // http://google.com/api/
path
url的路径部分
var url = new Url("http://baidu.com/api/get?id=1");
console.log(url.path); // /api/get
url.path = "api/post"
console.log(url.toString()); // http://baidu.com/api/post?id=1
query
url的参数部分
var url = new Url("http://baidu.com/api/get?id=1#title");
console.log(url.query); // id=1
url.query = "name=1&sex=男"
console.log(url.toString()); // http://baidu.com/api/get?name=1&sex=%E7%94%B7#title
url.query = ""
console.log(url.toString()); // http://baidu.com/api/get#title
params
url的参数部分被解释后的实体对象
var url = new Url("http://baidu.com/api/get?id=1#title");
console.log(url.params.id); // 1
url.params.id = 2;
url.params.name = "blqw";
console.log(url.toString()); // http://baidu.com/api/get?id=2&name=blqw#title
anchor
url的锚记部分
var url = new Url("http://baidu.com/api/get?id=1#title");
console.log(url.anchor); // #title
url.anchor = "content";
console.log(url.toString()); // http://baidu.com/api/get?id=1#content
url.anchor = "";
console.log(url.toString()); // http://baidu.com/api/get?id=1
