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"}

我很早以前就发现了这一点，非常简单：

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi,    
    function(m,key,value) {
      vars[key] = value;
    });
    return vars;
  }

然后这样称呼：

var fType = getUrlVars()["type"];

最短路径：

new URL(location.href).searchParams.get("my_key");

function parseUrl(url){
    let urlParam = url.split("?")[1];
    console.log("---------> URL param : " + urlParam);
    urlParam = urlParam.split("&");
    let urlParamObject = {};
    for(let i=0;i < urlParam.length;i++){
        let tmp = urlParam[i].split("=");
        urlParamObject[tmp[0]] = tmp[1];
    }
    return urlParamObject;
}

let param = parseUrl(url);
param.a // output 10
param.b // output 20

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;
}

获取单个参数值：

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