一个班轮。干净简单。

const params = Object.fromEntries(new URLSearchParams(location.search));

对于您的具体情况，它将是:

const str = 'abc=foo&def=%5Basf%5D&xyz=5'; const params = Object.fromEntries(new URLSearchParams(str)); console.log (params);

/** * Parses and builds Object of URL query string. * @param {string} query The URL query string. * @return {!Object<string, string>} */ function parseQueryString(query) { if (!query) { return {}; } return (/^[?#]/.test(query) ? query.slice(1) : query) .split('&') .reduce((params, param) => { const item = param.split('='); const key = decodeURIComponent(item[0] || ''); const value = decodeURIComponent(item[1] || ''); if (key) { params[key] = value; } return params; }, {}); } console.log(parseQueryString('?v=MFa9pvnVe0w&ku=user&from=89&aw=1')) see log

首先你需要定义什么是get变量:

function getVar()
{
    this.length = 0;
    this.keys = [];
    this.push = function(key, value)
    {
        if(key=="") key = this.length++;
        this[key] = value;
        this.keys.push(key);
        return this[key];
    }
}

而不是直接读:

function urlElement()
{
    var thisPrototype = window.location;
    for(var prototypeI in thisPrototype) this[prototypeI] = thisPrototype[prototypeI];
    this.Variables = new getVar();
    if(!this.search) return this;
    var variables = this.search.replace(/\?/g,'').split('&');
    for(var varI=0; varI<variables.length; varI++)
    {
        var nameval = variables[varI].split('=');
        var name = nameval[0].replace(/\]/g,'').split('[');
        var pVariable = this.Variables;
        for(var nameI=0;nameI<name.length;nameI++)
        {
            if(name.length-1==nameI) pVariable.push(name[nameI],nameval[1]);
            else var pVariable = (typeof pVariable[name[nameI]] != 'object')? pVariable.push(name[nameI],new getVar()) : pVariable[name[nameI]];
        }
    }
}

并使用like:

var mlocation = new urlElement();
mlocation = mlocation.Variables;
for(var key=0;key<mlocation.keys.length;key++)
{
    console.log(key);
    console.log(mlocation[mlocation.keys[key]];
}

到目前为止，我发现的建议解决方案并没有涵盖更复杂的场景。

我需要像这样转换查询字符串

https://random.url.com?Target=Offer&Method=findAll&filters%5Bhas_goals_enabled%5D%5BTRUE%5D=1&filters%5Bstatus%5D=active&fields%5B%5D=id&fields%5B%5D=name&fields%5B%5D=default_goal_name

变成一个像这样的物体:

{
    "Target": "Offer",
    "Method": "findAll",
    "fields": [
        "id",
        "name",
        "default_goal_name"
    ],
    "filters": {
        "has_goals_enabled": {
            "TRUE": "1"
        },
        "status": "active"
    }
}

OR:

https://random.url.com?Target=Report&Method=getStats&fields%5B%5D=Offer.name&fields%5B%5D=Advertiser.company&fields%5B%5D=Stat.clicks&fields%5B%5D=Stat.conversions&fields%5B%5D=Stat.cpa&fields%5B%5D=Stat.payout&fields%5B%5D=Stat.date&fields%5B%5D=Stat.offer_id&fields%5B%5D=Affiliate.company&groups%5B%5D=Stat.offer_id&groups%5B%5D=Stat.date&filters%5BStat.affiliate_id%5D%5Bconditional%5D=EQUAL_TO&filters%5BStat.affiliate_id%5D%5Bvalues%5D=1831&limit=9999

成:

{
    "Target": "Report",
    "Method": "getStats",
    "fields": [
        "Offer.name",
        "Advertiser.company",
        "Stat.clicks",
        "Stat.conversions",
        "Stat.cpa",
        "Stat.payout",
        "Stat.date",
        "Stat.offer_id",
        "Affiliate.company"
    ],
    "groups": [
        "Stat.offer_id",
        "Stat.date"
    ],
    "limit": "9999",
    "filters": {
        "Stat.affiliate_id": {
            "conditional": "EQUAL_TO",
            "values": "1831"
        }
    }
}

我将多个解决方案编译并调整为一个实际有效的解决方案:

代码:

var getParamsAsObject = function (query) {

    query = query.substring(query.indexOf('?') + 1);

    var re = /([^&=]+)=?([^&]*)/g;
    var decodeRE = /\+/g;

    var decode = function (str) {
        return decodeURIComponent(str.replace(decodeRE, " "));
    };

    var params = {}, e;
    while (e = re.exec(query)) {
        var k = decode(e[1]), v = decode(e[2]);
        if (k.substring(k.length - 2) === '[]') {
            k = k.substring(0, k.length - 2);
            (params[k] || (params[k] = [])).push(v);
        }
        else params[k] = v;
    }

    var assign = function (obj, keyPath, value) {
        var lastKeyIndex = keyPath.length - 1;
        for (var i = 0; i < lastKeyIndex; ++i) {
            var key = keyPath[i];
            if (!(key in obj))
                obj[key] = {}
            obj = obj[key];
        }
        obj[keyPath[lastKeyIndex]] = value;
    }

    for (var prop in params) {
        var structure = prop.split('[');
        if (structure.length > 1) {
            var levels = [];
            structure.forEach(function (item, i) {
                var key = item.replace(/[?[\]\\ ]/g, '');
                levels.push(key);
            });
            assign(params, levels, params[prop]);
            delete(params[prop]);
        }
    }
    return params;
};

如果你正在使用URI.js，你可以使用:

https://medialize.github.io/URI.js/docs.html#static-parseQuery

var result = URI.parseQuery("?foo=bar&hello=world&hello=mars&bam=&yup");
result === {
  foo: "bar",
  hello: ["world", "mars"],
  bam: "",
  yup: null
};

使用ES6, API和URLSearchParams。

function objectifyQueryString(url) {
  let _url = new URL(url);
  let _params = new URLSearchParams(_url.search);
  let query = Array.from(_params.keys()).reduce((sum, value)=>{
    return Object.assign({[value]: _params.get(value)}, sum);
  }, {});
  return query;
}
