<h1>Passing an object of parameters into a function</h1>
<div class="result"><br /></div>
<button class="btn">点击此处</button>
<h3>Click on the above button to add 4 object values by passing them to a function</h3>
<script>
   let resEle = document.querySelector(".result");
   let BtnEle = document.querySelector(".Btn");
   function addNum({ a, b, c, d }) {
      return a + b + c + d;
   }
   let obj = {
      a: 22,
      b: 33,
      c: 7,
      d: 9,
   };
   BtnEle.addEventListener("click", () => {
      resEle.innerHTML = " The sum of the parameters = " + addNum(obj);
   });
</script>
</body>
