I need a function to trigger if the element recordplayerstick contains either the pinplace or pinsongplay class. The code I currently have returns a syntax error. What is the correct way to do this?

if (document.getElementById('recordplayerstick').classList.contains('pinplace pinsongplay')) {
    removepin();
}

推荐答案

如果要使用classList，则必须做两项检查.

You are going to have to do two checks if you are going to use classList.

function removepin() {
  console.log("yep");
}
var cList = document.getElementById('recordplayerstick').classList;
if (
  cList.contains('pinplace') ||
  cList.contains('pinsongplay')) {
  removepin();
}

<div id="recordplayerstick" class="pinplace pinsongplay"></div>
