2. url参数解析为数组
3. URLSearchParams(兼容性有待提高，慎用)

url参数解析为对象

const urlQueryToObject = (url) => { if((/\?/).test(url)) { const arr = url.split('?')[1].split('&'); return arr.reduce((acc,value,index) => {value.replace(/(\w+)=(\w+)/,(match,p1,p2) => {acc[p1] = p2});return acc},{}); } return {}}const getURLParameters = url => (url.match(/([^?=&]+)(=([^&]*))/g) || []).reduce( (a, v) => ((a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1)), a), {});

// example// location.href ='http://example.com/user?id=1&age=2'const paramsObj = urlQueryToObject(location.href) //{id: "1", age: "2"}paramsObj.id paramsObj.age

url参数解析为数组

const urlQueryToArr = url => { if((/\?/).test(url)) { const arr = url.split('?')[1].split('&'); return arr.reduce((acc,value,index) => {acc.push(value.split('='));return acc;},[]) } return []}

// example// location.href ='http://example.com/user?id=1&age=2' JSON.stringify(urlQueryToArr(location.href)) // "[["id","1"],["age","2"]]"

URLSearchParams

/** * * @param {string} url * @return URLSearchParams ; */const urlParams = url => { if(/\?/.test(url)) { return searchParams = new URLSearchParams( url.split('?')[1]); } return new URLSearchParams()}

useage

// location.href ='http://example.com/user?id=1&age=2' const params = urlParams(location.href); //iterater objparams.get('id') // 1params.has('id') // trueparams.append('id','2')params.getAll('id') // ?["1", "2"]params.set('id','0') params.get('id') // "0"params.getAll('id') // ["0"]params.delete('id')params.get('id') // nullparams.toString() //"age=2"
