尝试使用events (as a function)从geojson导入数据,但是什么也没显示。缺少针对我的特定案例的v4示例,这使我感到困难,并且缺少错误。我的代码如下。根据myevents函数中的debug.log(eventlist),正确创建了“事件列表”。由于某些原因,我的活动无法显示。
任何帮助都会很棒

答案 0 :(得分:1)
如果您记录每个obj
的创建并记录日志在控制台中的显示顺序(特别是与记录整个事件列表的时间相比),您可能会开始发现问题-通过此方法进行观察演示:https://codepen.io/ADyson82/pen/pMEZNE。还要记住,Chrome之类的浏览器可以追溯性地动态填充对象的日志(换句话说,它可以创建日志条目,然后在代码中更新对象时稍后向其中添加数据),这在您使用时并不总是有用的正在尝试调试此类问题。
我要说的是,您没有考虑到脚本文件将异步 ...
加载的事实。幸运的是,由于fullCalendar已经为您提供了successCallback
,以便您随时准备返回事件时都可以调用它,这对于处理异步方案是理想的。您可以简单地在异步eq_feedbackCallback中调用successCallback。这样可以确保在实际填充事件列表之前,不要将其发送到fullCalendar。
function myevents(info, successCallback, failureCallback) {
var script = document.createElement("script");
script.src =
"https://uploads-ssl.webflow.com/5b5a1fce48210813dc66ccb6/5d2f8540e5892f506213cb11_Output.txt";
document.getElementsByTagName("head")[0].appendChild(script);
window.eqfeed_callback = function(results) {
var eventlist = [];
for (var i = 0; i < results.features.length; i++) {
var obj = {};
obj["title"] = results.features[i].properties.eventname;
obj["start"] = results.features[i].properties.datestart;
obj["end"] = results.features[i].properties.dateend;
eventlist.push(obj);
}
successCallback(eventlist);
};
}
document.addEventListener("DOMContentLoaded", function() {
var calendarEl = document.getElementById("calendar");
var calendar = new FullCalendar.Calendar(calendarEl, {
plugins: ["interaction", "dayGrid"],
defaultView: "dayGridMonth",
contentHeight: "auto",
header: { left: "prev,next", center: "", right: "title" },
events: myevents
});
calendar.render();
});
