无法让我的 openlayers 地图显示在网页上

Can't get my openlayers map to appear on a web page

本文关键字:显示 网页 地图 openlayers 我的      更新时间:2023-09-26

我已经在jsfiddle中制作了一个开放图层地图,我想把它托管在我的域上。 这是jsfiddle。 我将html,js和css复制到我的域中,它应该在这里可见。

如您所见,它没有按预期工作。 我对在使用 jsfiddle 和实际托管它之间需要更改的内容感到困惑,因为我觉得有一些我不知道的快捷方式正在完成。

这是用于每个的代码(我已经对其进行了一些修改,以尝试使其在常规域而不是jsfiddle上工作)(我还应该注意html,js和css都存储在main.html,map.js和style_1.css相同的文件夹中):

你有这个火虫

TypeError: closer is null

closer.onclick = function() {

将 js 放在 Document ready 函数中。

$( document ).ready(function() { //place your js here var container = document.getElementById('popup'); var content = document.getElementById('popup-content-description'); var closer = document.getElementById('popup-closer'); ............................... });

在JSFIDDLE中,一旦HTML被渲染,JS就会被执行。
