获取地址栏参数

1、通过正则获取

function getParams(){
        let url = window.location.search;
        let obj = {};
        let reg = /[?&][^?&]+=[^?&]+/g;
        let arr = url.match(reg);
        if(arr){
            arr.forEach((item)=>{
                let tempArr = item.substring(1).split("=");
                let key = tempArr[0];
                let val = tempArr[1];
                obj[key] = val;
            })
        }
        return obj

    }
    console.log(getParams());
