我正在开发一个提供 jvectormap 节点类型的 Drupal 模块。除了 drupal 一切正常.load()。我用
jQuery("#content").load(Drupal.settings.jvectormapnode.url+'/'+ code +'?ajax=1');
发生以下情况，我单击地图上的一个国家，这调用 /content/institutes/BE
/content/institutes is an views page with a contextual filter witch grabs the last part of the url and displays some data.
jvectormap 节点通过迷你面板和块包含在同一页面上（视图位于 div #content 中，jvectormap 位于迷你面板块中）
到目前为止一切正常。现在，当我单击第二个区域时，URL 突然切换到/content/undefined.
让我用一个例子来澄清一下：我单击比利时，URL 更改为 /content/institutes/BE，视图选择了它，然后我单击法国，URL 更改为 /content/undefined，但视图仍然正确反应并显示法国信息。现在我按 F5 刷新浏览器，drupal 说 /content/undefined 不存在。如果我在第一次单击（比利时）后按 F5，它会正确重新加载页面。该问题似乎发生在连续的 ajax 请求中。我可以用一个 url 别名来解决这个问题，这样就可以处理 F5 刷新边缘情况，看到其他一切正常，但如果其他人需要多个节点，他们就有一个（小）问题。
我怀疑.load这是发生这种情况的原因。
欢迎任何帮助谢谢。
