我正在研究一个提供jvectormap节点类型的Drupal模块。
除了drupal .load()之外，一切正常。我用
jQuery("#content").load(Drupal.settings.jvectormapnode.url+'/'+ code +'?ajax=1');
如果点击地图上的某个国家/地区，则会发生以下情况：此内容/内容/机构/ 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和迷你面板块中的jvectormap）
到目前为止一切正常。现在当我点击第二个区域时，URL突然切换到/content/undefined。
让我用一个例子来澄清：我点击比利时URL更改为/ content / institutes / BE并且视图选择了这个，然后我单击France并且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。如果我在第一次点击（比利时）后点击F5，它会正确地重新加载页面。连续的ajax请求似乎发生了这个问题。我想用一个url别名来解决这个问题，这样就可以处理F5刷新边缘情况，看看其他一切都能正常工作，但是如果其他人需要多个节点，他们就会遇到（小）问题。
我怀疑.load是发生这种情况的原因。
欢迎任何帮助，谢谢。

似乎code回调中传递的onRegionClick参数未定义。
你可以用console.log()那个参数知道确切的值吗？通常这应该是区域代码作为字符串。 （即：'BE'，'NL'，......）
onRegionClick: function (event, code) {
console.log(code);
}
答案 1 :(得分：0)
我发现了导致未定义的原因，这里是可行的代码
jQuery("#content").load(Drupal.settings.jvectormapnode.url+'/'+ code ,'ajax=1' ,
function() {Drupal.attachBehaviors('#content');});
希望这有助于其他人
