我的解决方案扩展了@tak3r的。

当没有查询参数时返回空对象，并支持数组符号?a=1&a=2&a=3:

function getQueryParams () {
  function identity (e) { return e; }
  function toKeyValue (params, param) {
    var keyValue = param.split('=');
    var key = keyValue[0], value = keyValue[1];

    params[key] = params[key]?[value].concat(params[key]):value;
    return params;
  }
  return decodeURIComponent(window.location.search).
    replace(/^\?/, '').split('&').
    filter(identity).
    reduce(toKeyValue, {});
}

一种更花哨的方法::)

var options = window.location.search.slice(1)
                      .split('&')
                      .reduce(function _reduce (/*Object*/ a, /*String*/ b) {
                        b = b.split('=');
                        a[b[0]] = decodeURIComponent(b[1]);
                        return a;
                      }, {});

我这样做(检索一个特定的get-parameter，这里'parameterName'):

var parameterValue = decodeURIComponent(window.location.search.match(/(\?|&)parameterName\=([^&]*)/)[2]);

如果您不介意使用库而不是自己的实现，请查看https://github.com/jgallen23/querystring。

这是另一个基于Kat和Bakudan例子的例子，但让它更通用一点。

function getParams ()
{
    var result = {};
    var tmp = [];

    location.search
        .substr (1)
        .split ("&")
        .forEach (function (item)
        {
            tmp = item.split ("=");
            result [tmp[0]] = decodeURIComponent (tmp[1]);
        });

    return result;
}

location.getParams = getParams;

console.log (location.getParams());
console.log (location.getParams()["returnurl"]);

你应该使用URL和URLSearchParams本地函数:

let url = new url ("https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8&q=mdn%20query%20string") let params = new URLSearchParams(url.search); Let sourceid = params.get('sourceid') // 'chrome-instant' Let q = params.get('q') // 'mdn查询字符串' 让ie = params.has('ie') // true params.append(“平”、“乒乓球”) console.log (sourceid) console.log (q) console.log (ie) console.log (params.toString ()) console.log (params.get(“平”))
