Regular expression in javascript to check date is embded with text

Question

I need to check whether the text contains a date part with it.

for ex: mytext_12/26/2011_11:51_AM or someText_12/26/2011_13:51_PM have a date part it returns true.

I am not too good with expressions so looking for one. the format of the date part is fixed.

Answer 1

To merely test for the presence of a date in a string...

var containsDate = ~str.search(/\d{1,2}\/\d{1,2}\/\d{4}/);

If you wanted to check the time at the end too, add _\\d{1,2}:\\d{2}_(?:AM|PM) .
