Another "Uncaught SyntaxError: Unexpected identifier"

Question

拜托，我在使用 sntax 时遇到了问题，我不知道为什么。我的剧本是

var popup = document.getElementById("mypopup");
var span = document.getElementsByClassName("close-btn")[0];
var sticker = document.getElementsByClassName("sticker")[0];

window.onload = function() {
  popup.style.display = "inline-block";
  sticker.style.display = "none";
}

span.onclick = function() {
  popup.style.display = "none";
  sticker.style.display = "inline-block";
}

window.onclick = function(event) {
  if (event.target == popup) {
    popup.style.display = "none";
    sticker.style.display = "block";
  }
}

似乎错误在行

span.onclick = function() {

控制台消息只是“Uncaught SyntaxError: Unexpected identifier”并且只出现在生产环境中。

希望你能救救我！

您需要使用 addEventListener 像这样 span.addEventListener("onclick", yourFunction) 或者它不起作用
