我正在构建我的第一个 JQM 网站，所以我认为我错过了一些简单的小事情，这给我带来了很多问题。
我已经设置了页面、页眉、内容和页脚以及菜单面板。然后我有一个 js 文件，其中包含以下内容：
$(document).on('pageinit', function (event) {
alert('this works every time you navigate to another page');
$("#menu-panel").panel("open");//this works the first time only
$("#new-lump-sum").popup("open");//this never works
});
谁能告诉我为什么每次导航到另一个页面时都会出现这种行为，而不是面板和弹出窗口？
我也无法从浏览器控制台以编程方式打开它们（使用 Chrome）
这是我的 HTML：

当页面事件发生后立即打开弹出窗口和对话框时，它们会很棘手。要解决此问题，您需要使用setTimeout打开对话框或弹出窗口。
$(document).on('pageinit', function() {
setTimeout(function () {
$('#new-lump-sum').popup('open');
}, 100); // delay above zero
});
