优雅、实用的解决方案

让我们创建一个包含URL参数名作为关键字的对象，然后我们可以通过其名称轻松提取参数：

// URL: https://example.com/?test=true&orderId=9381  

// Build an object containing key-value pairs
export const queryStringParams = window.location.search
  .split('?')[1]
  .split('&')
  .map(keyValue => keyValue.split('='))
  .reduce<QueryStringParams>((params, [key, value]) => {
    params[key] = value;
    return params;
  }, {});

type QueryStringParams = {
  [key: string]: string;
};


// Return URL parameter called "orderId"
return queryStringParams.orderId;

一个内衬和IE11友好：

> (window.location.href).match('c=([^&]*)')[1]
> "m2-m3-m4-m5"

获取单个参数值：

function getQueryParameter(query, parameter) {
return (window.location.href.split(parameter + '=')[1].split('&')[0]);}

使用URLSearchParams的超简单方法。

function getParam(param){
  return new URLSearchParams(window.location.search).get(param);
}

目前，Chrome、Firefox、Safari、Edge和其他浏览器都支持它。

以下是我的解决方案：jsfiddle

下面的方法返回一个包含给定URL参数的字典。如果没有参数，则为空。

function getParams(url){
    var paramsStart = url.indexOf('?');
    var params = null;

    //no params available
    if(paramsStart != -1){
        var paramsString = url.substring(url.indexOf('?') + 1, url.length);

        //only '?' available
        if(paramsString != ""){
            var paramsPairs = paramsString.split('&');

            //preparing
            params = {};
            var empty = true;
            var index  = 0;
            var key = "";
            var val = "";

            for(i = 0, len = paramsPairs.length; i < len; i++){
                index = paramsPairs[i].indexOf('=');

                //if assignment symbol found
                if(index != -1){
                    key = paramsPairs[i].substring(0, index);
                    val = paramsPairs[i].substring(index + 1, paramsPairs[i].length);

                    if(key != "" && val != ""){

                        //extend here for decoding, integer parsing, whatever...

                        params[key] = val;

                        if(empty){
                            empty = false;
                        }
                    }                    
                }
            }

            if(empty){
                params = null;
            }
        }
    }

    return params;
}

以json形式从window.location中的搜索对象中提取所有url参数

export const getURLParams = location => {
    const searchParams = new URLSearchParams(location.search)
    const params = {}

    for (let key of searchParams.keys()) {
        params[key] = searchParams.get(key)
    }

    return params
}

console.log(getURLParams({ search: '?query=someting&anotherquery=anotherthing' }))

// --> {query: "someting", anotherquery: "anotherthing"}
