获取全部参数
function getParams(url) {try {url = url.match(/\?([^#]+)/)[1];const obj = {};const arr = url.split('&');for (let i = 0; i < arr.length; i++) {let subArr = arr[i].split('=');let key = decodeURIComponent(subArr[0]);let value = decodeURIComponent(subArr[1]);obj[key] = value;}return obj;} catch (err) {return null;}}var urlStr = '/test?name=zhangshan&age=50#hello';getParams(urlStr); //{name: "zhangshan", age: "50"}
获取单个参数值
function getParam(url, key){var pattern = new RegExp('[?&]*'+ key +'=([^&]+)');try {var value = url.match(pattern)[1];return value;} catch (err) {return null;}}var url = '/test?name=zhangshan&age=50#hello'; var key = 'name';getParam(url, key); // zhangshan
