Chrome DatePicker problem, it bothered me all afternoon_html/css_WEB-ITnose

There is a date input box in the page form. The date format is dd/MM/YYYY. I use JQuery UI DatePicker. Then I found a very strange phenomenon. Chorme will verify it for me according to MM/dd/YYYY. Verify If the date is wrong, it will not be submitted. Then focus on the date input box, and the calendar plug-in will pop up and let me select the date again. There is no problem with IE and FF. The new version of chrome has a native datepicker function. Is it because of it?
I beg for a solution.

It should not be affected by native datepicker.
DatePicker has
"option", "dateFormat" to set the format. You set it ?

In addition, the general format Y is lowercase, you can try changing it to yyyy

I wrote it wrong. I have set dateFormat: 'dd/mm/yy', and the selected date will also follow this format. For example, today: 18/04/2013
In this way, the submission will focus on the date input box. If you enter 12/04/2013, it will be submitted. I guess chrome regards the first one as the month, and 18 does not exist. So I was asked to re-enter the date and did nothing else, not sure how to debug this issue. All other browsers are fine, but something is wrong with Chrome, so frustrating!
