jquery select from within element

问题

How do I do this (but in a way that works):

$("MyElem").get("[id$='Date']").datepicker();

Essentially I'm trying to select all elements that end with the word "Date" in the id within the context of a given parent element.

So this should be interpreted as:

1. Get "MyElem".
2. From "MyElem" search all children recursively and find id's that end with "Date".
3. For each item in the results of step 2 call datepicker on that element

$('#myelem').find('[id&=Date]').datepicker();

Or why not using a better selector:

$('#myelem *[id$=Date]').datepicker();
