Answer 1

Answer 2

function getParamsObject(query){
    return query
        .split('&')
        .map(substring=>substring.split('='))
        .reduce((a,c)=>{
            const [key,value] = c;
            a[key] = value;
            return a;
         },{})
}
const result = getParamsObject('id=4&manufactorId=4')//{id: '4', manufactorId: '4'}

Answer 3

// 实现方法很多，随便写了一种
function fn(str) {
  return Object.fromEntries(str.split('&').map(v => v.split('=')))
}
const obj = fn('id=4&manufactorId=4')
console.log(obj)

Answer 4

function paramsFormate(str) {
    if (str) {
      return Object.fromEntries(new URLSearchParams(str));
    }
  }

Answer 5

const obj = {};
'id=4&manufactorId=4'.replace(/([^&=]+)=([^&=]*)/g, (_,k,v)=>{
    let $v = decodeURIComponent(v);
    if (!isNaN($v)) {
        $v = Number($v);
    }
    obj[k] = $v;
}
);
console.log(obj);
