推荐答案

As @Bluetoft说，答案是事件委托。

As @Bluetoft says, the answer is event delegation.

它不适合你的原因是因为你的datepicker被绑定到当时存在的元素脚本运行（更不要说生日字段的ID与#datepicker不同，这是您的脚本绑定的）。

The reason it's not working for you is because your datepicker is being bound to elements that exist at the time the script is run (not to mention, the birthday field has a different id than #datepicker, which is what your script is binding to).

当你动态地引入新的形式，datepicker并不绑定到新元素。

When you dynamically bring in the new form, the datepicker is not bound to the new elements.

所以，根据是构建你的脚本，如下所示：

So, one method, according to this answer, is to construct your script like so:

$(function() {
    $("body").delegate("#datepicker", "focusin", function(){
        $(this).datepicker();
    });
});

另外，您的表单生日输入的ID为#fi_bday这是另一个没有约束力的原因。我建议您使用datepicker类别将datepicker分配给任何输入，然后更改脚本以将datepicker功能绑定到'。datepicker'元素：

Additionally, your form "birthday" input has an id of #fi_bday, which is another reason it's not being bound. I'd recommend that you assign any inputs where you want the datepicker with a class of "datepicker", then change your script to bind the datepicker functionality to '.datepicker' elements:

$(function() {
    $("body").delegate(".datepicker", "focusin", function(){
        $(this).datepicker();
    });
});

最后，如果不想利用更好的通用上面的类方法，可以在下面的选择器中使用两个选择器。下面的方法代表将datepicker绑定到模态窗口元素的方式：

Finally, if you don't want to utilize the better, generic class method above, you can use two selectors in the selector below. The method below delegates in a manner as to bind the datepicker to the modal window element(s) as well:

$(function() {
    $("body").delegate("#datepicker, #fi_bday", "focusin", function(){
        $(this).datepicker();
    });
});
