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;
}

我也遇到了同样的问题，尝试了这里的解决方案，但没有一个真正有效，因为我在URL参数中有数组，像这样:

?param[]=5&param[]=8&othr_param=abc&param[]=string

所以我最终写了我自己的JS函数，它使一个数组的参数在URI:

/**
 * Creates an object from URL encoded data
 */
var createObjFromURI = function() {
    var uri = decodeURI(location.search.substr(1));
    var chunks = uri.split('&');
    var params = Object();

    for (var i=0; i < chunks.length ; i++) {
        var chunk = chunks[i].split('=');
        if(chunk[0].search("\\[\\]") !== -1) {
            if( typeof params[chunk[0]] === 'undefined' ) {
                params[chunk[0]] = [chunk[1]];

            } else {
                params[chunk[0]].push(chunk[1]);
            }


        } else {
            params[chunk[0]] = chunk[1];
        }
    }

    return 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

console.log (decodeURI (' abc = foo&def = % 5巴斯夫% 5 d&xyz = 5 ') .split (' & ') .reduce((result, current) => { Const [key, value] = current.split('='); 结果[key] = value; 返回结果 }, {}))

下面是我用的一个例子:

var params = {};
window.location.search.substring(1).split('&').forEach(function(pair) {
  pair = pair.split('=');
  if (pair[1] !== undefined) {
    var key = decodeURIComponent(pair[0]),
        val = decodeURIComponent(pair[1]),
        val = val ? val.replace(/\++/g,' ').trim() : '';

    if (key.length === 0) {
      return;
    }
    if (params[key] === undefined) {
      params[key] = val;
    }
    else {
      if ("function" !== typeof params[key].push) {
        params[key] = [params[key]];
      }
      params[key].push(val);
    }
  }
});
console.log(params);

基本用法。 ? = aa&b = bb 对象{a: "aa"， b: "bb"}

重复参数，例如。 ? = aa&b = bb&c = cc&c =土豆 对象{a: "aa"， b: "bb"， c: ["cc"，"potato"]}

钥匙不见了。 ? = aa&b = bb = cc 对象{a: "aa"， b: "bb"}

缺少值，例如。 = aa&b = bb&c ? 对象{a: "aa"， b: "bb"}

上述JSON/regex解决方案在这个古怪的url上抛出了一个语法错误: ? = aa&b = bb&c = & = dd&e 对象{a: "aa"， b: "bb"， c: ""}

//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;
}
