Inialize a jQuery textfield-datepicker w/ today's date in the format yyyy-mm-dd

问题

I'm using a jQuery datepicker attached to a text input. Is there a datepicker action that can inialize the text field w/ today's date (yyyy-mm-dd) when the page loads?

回答1:

Initialize the datepicker with the date format and set the date -

$( ".selector" ).datepicker({ dateFormat: 'yy-mm-dd'})
$( ".selector" ).datepicker( "setDate" , new Date())

回答2:

You can set a default date to a fixed or relative value:

// Only necessary if you are sending data using a different format
$( ".selector" ).datepicker({ altFormat: 'yy-mm-dd' });
// Initialize to a fixed date
$( ".selector" ).datepicker({ defaultDate: '2011-10-20' });
// or to a relative date
$( ".selector" ).datepicker({ defaultDate: +7 });

Assuming that you're using the datepicker from jQueryUI, you can explicitly set its value directly after initializing it:

$('#id').datepicker();
$('#id').datepicker('setDate', new Date);
