一、获取查询参数：

/**
 * @description 获取页面地址中的参数
 * @author ""
 * @date 2018-08-29
 * @export
 * @param {string} url(可以为空，为空即为当前页面地址)
 * @returns {object}
 */
function getQueryParam(url) {
	url = url == null ? window.location.href : url;
	let search = url.substring(url.lastIndexOf('?') + 1);
	let query = {};
	let reg = /([^?&=]+)=([^?&=]*)/g;
	search.replace(reg, (rs, $1, $2) => {
		let name = decodeURIComponent($1);
		let val = decodeURIComponent($2);
		val = String(val);
		query[name] = val;
		return rs;
	});
	return query;
}

二、拼接查询参数：

/**
 * @description 拼接查询参数
 * @author ""
 * @date 2018-08-29
 * @export
 * @param {string} url 需要拼接的地址
 * @param {param} 需要拼接的参数
 * @returns {string}
 */
function createURL(url, param) {
	let Url;
	let queryStr = '';
	for (let key in param) {
		let link = '&' + key + "=" + param[key];
		queryStr += link;
	}
	Url = url + "?" + queryStr.substr(1);
	return Url;
}
