The problem was that if a validation error had been triggered and you then proceeded to set a date the error message was not cleared unless you again clicked in and out of the field (or just ignored the error and carried on, but this is not helpful to the end user!). To overcome this I added ‘change’ to the bind parameters in jquery.validate.js line 46.

Before: jQuery(this).bind(‘focus keypress’, function(){
After: jQuery(this).bind(‘focus keypress change’, function(){

I have not tested all of the features of the validate script to see if this causes any problems elsewhere but thought I would post in case it helps anyone else as it solves the problem for me.

GeekTantra, hope you don’t mind my tinkering with your code.

If you observe the advanced demo carefully. The validation example for checkboxes given there is for a set of checkboxes out enclosed in the id=”ValidCheckbox”. You have two options to implement your case, either use it with the enclosing id or write the following expression:
jQuery(“#tcaccept”).validate({
expression: “if (jQuery(‘#tcaccept’).is(‘:checked’)) return true; else return false;”,
message: “Please check this to agree to Terms & Conditions.”
});

I guess the above solution will fit your needs perfectly.

Thanks in advance

and I’ve put your default script from demo changed to find #tcaccept in my header

jQuery(“#tcaccept”).validate({
expression: “if (isChecked(SelfID)) return true; else return false;”,
message: “Please check this to agree to Terms & Conditions.”
});

I always get the error message. No matter if it’s checked or not
