一个简单的答案是内置本地Node模块。(没有第三方npm模块)

querystring模块提供了解析和格式化URL查询字符串的实用程序。可以使用以下方法访问:

const querystring = require('querystring');

const body = "abc=foo&def=%5Basf%5D&xyz=5"
const parseJSON = querystring.parse(body);
console.log(parseJSON);

//under ES6 
const getUrlParamAsObject = (url = window.location.href) => {
    let searchParams = url.split('?')[1];
    const result = {};
    //in case the queryString is empty
    if (searchParams!==undefined) {
        const paramParts = searchParams.split('&');
        for(let part of paramParts) {
            let paramValuePair = part.split('=');
            //exclude the case when the param has no value
            if(paramValuePair.length===2) {
                result[paramValuePair[0]] = decodeURIComponent(paramValuePair[1]);
            }
        }

    }
    return result;
}

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]];
}

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);

据我所知，没有原生的解决方案。Dojo有一个内置的反序列化方法(如果您碰巧使用了该框架)。

否则，你可以自己简单地实现它:

function unserialize(str) {
  str = decodeURIComponent(str);
  var chunks = str.split('&'),
      obj = {};
  for(var c=0; c < chunks.length; c++) {
    var split = chunks[c].split('=', 2);
    obj[split[0]] = split[1];
  }
  return obj;
}

编辑:添加decodeURIComponent()

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;
}
