传单地图不会出现

Question

I'm trying to use a map, but it doesn't seem to work it just shows an empty white space.我正在尝试使用地图，但它似乎不起作用，它只显示一个空白区域。 I hard reseted my pc days ago, so I'm not sure if something is missing in my pc or my code is wrong, but here it is:几天前我硬重置了我的电脑，所以我不确定我的电脑是否缺少某些东西或我的代码有问题，但这里是：

      var mapa = document.getElementById('mapa');
      if(mapa) {

        L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {

            .bindTooltip('Paris WebCamp 2020<br> Boletos disponibles.')
            .openTooltip();
      }

  });
});

index.php:索引.php：

<div id="mapa" class="mapa"></div>

After everything... it doesnt show, it's just a blank space in my web毕竟......它没有显示，它只是我网络中的一个空白区域

Your IIFE is never invoked:你的 IIFE 永远不会被调用：

(function () {
  // some code...
}); // Function is expressed but not invoked

Should be:应该：

(function () {
  // some code...
})(); // Make sure to add the final parenthesis pair

Just for completeness, it also works with the calling parenthesis pair just after the braces:为了完整起见，它也适用于大括号后面的调用括号对：

(function () {
  // some code...
}());
