Copy Code code as follows:

var beginvalue = "Start Time";
var endvalue = "End Time";
var dispaly = jQuery ("#testSubjectGrid"). Jqgrid ("Getcell", Idarray[i), "display_content");
if (Checkdate (Begindata, dispaly, beginvalue) = = False) {
return false;
}
if (Checkdate (Enddata, dispaly, endvalue) = = False) {
return false;
}

Validation of dates (YYYY-MM-DD)
