JavaScript 功能类 Url.js

    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

    Github
    Url.combine展示

    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)

    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
