將url參數對象化

    function getUrlObj () {
        var obj ={};
        let params = window.location.search.replace(/^\?/, '');
        let paramArray = params.split("&");
        for (let i = 0; i < paramArray.length; i++) {
            let itemArray = paramArray[i].split('=');
            let k = itemArray[0];
            let v = decodeURIComponent(itemArray[1]);
            if (v && k) {
                obj[k] = v;
            }
        }
        return obj;
    }
