Question

提问by Ryan Grush

I know this question has been asked on SO before, but I can't figure out what I'm missing. Here is a simple Fiddle.

我知道之前已经在 SO 上问过这个问题，但我不知道我错过了什么。这是一个简单的Fiddle。

The jquery:

jQuery：

var myDate = new Date(1978,2,11) 
$('#datepicker').datepicker('setDate', myDate);

You have to initialize the datepicker first:

您必须先初始化日期选择器：

    $('#datepicker').datepicker();

When you pass setDate, you are calling a method which assumes the datepicker has already been initialized on that object.

当您传递 setDate 时，您正在调用一个方法，该方法假定日期选择器已在该对象上初始化。
