我有一个带有Datepicker的JSF页面。问题是当我使用AJAX将数据更新到页面时。执行AJAX操作后，页面是datepicker不能正常工作：

我测试了删除AJAX部分 - datepicker工作正常。你能告诉我为什么AJAX会阻止JavaScript工作吗？
答案 0 :(得分：4)
添加此项（不要替换当前代码）
$(window).load(function () {
jsf.ajax.addOnEvent(function(data) {
if (data.status === 'success') {
$(".datepicker").datepicker({
inline: true,
showWeek: true,
firstDay: 1,
dateFormat: 'dd-MM-yy'
});
}
});
});

是的，在AJAX更新后，Datepicker可能无法正常工作。
