window.location.href.split("?")

则忽略第一个索引

Array.prototype.slice.call(window.location.href.split("?"), 1) 

返回url参数数组

var paramArray = Array.prototype.slice.call(window.location.href.split(/[?=]+/), 1);
var paramObject = paramArray.reduce(function(x, y, i, a){ (i%2==0) ?  (x[y] = a[i+1]) : void 0; return x; }, {});

paramObject包含映射为js对象的所有参数

function getParamValue(param) {
    var urlParamString = location.search.split(param + "=");
    if (urlParamString.length <= 1) return "";
    else {
        var tmp = urlParamString[1].split("&");
        return tmp[0];
    }
}

无论参数是否为最后一个，这都适用于您的情况。

看看这个

function getURLParameters(paramName)
{
    var sURL = window.document.URL.toString();
    if (sURL.indexOf("?") > 0)
    {
        var arrParams = sURL.split("?");
        var arrURLParams = arrParams[1].split("&");
        var arrParamNames = new Array(arrURLParams.length);
        var arrParamValues = new Array(arrURLParams.length);

        var i = 0;
        for (i = 0; i<arrURLParams.length; i++)
        {
            var sParam =  arrURLParams[i].split("=");
            arrParamNames[i] = sParam[0];
            if (sParam[1] != "")
                arrParamValues[i] = unescape(sParam[1]);
            else
                arrParamValues[i] = "No Value";
        }

        for (i=0; i<arrURLParams.length; i++)
        {
            if (arrParamNames[i] == paramName)
            {
                //alert("Parameter:" + arrParamValues[i]);
                return arrParamValues[i];
            }
        }
        return "No Parameters Found";
    }
}

    function gup() {
    var qs = document.location.search;
    qs = qs.split('+').join(' ');
    var params = {}, tokens, re = /[?&]?([^=]+)=([^&]*)/g;
    while (tokens = re.exec(qs))
        params[decodeURIComponent(tokens[1])] = decodeURIComponent(tokens[2]);
    return params;
}

像这样使用

var params = gup()

然后

params.param1
params.param2

您可以通过以下函数实现：

function getParameter(parameterName){
        let paramsIndex = document.URL.indexOf("?");
        let params="";
        if(paramsIndex>0)
            params=document.URL.substring(paramsIndex+1, document.URL.length).split("&");
        let result = [];
        for(let i=0;i<params.length;i++)
        {
            console.warn(params[i].split("=")[0].toString()+ "," + params[i].split("=")[1].toString());
            var obj = {"key":params[i].split("=")[0].toString(),"value":params[i].split("=")[1].toString()};
            result.push(obj);
        }
        return passedValue = result.find(x=>x.key==parameterName).value;
    }

现在您可以使用getParameter（“parameterName”）获取参数值

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
