Step 2: Create a new region
Under identification you can give the title
Step 3: Create Page Items which need to be a date.
Step 4: Add Format Mask and Value placeholder.
Step 5: Now Create a following script on Global page.
<script>
function validateDate(date){
var regex=new RegExp(“([0-9]{4}[-|/](0[1-9]|1[0-2])[-|/]([0-2]{1}[0-9]{1}|3[0-1]{1})|([0-2]{1}[0-9]{1}|3[0-1]{1})[-|/](0[1-9]|1[0-2])[-|/][0-9]{4})”);
var dateOk=regex.test(date);
if(dateOk){ return 1;
}else{ return 0;
}
}
</script>
Step 6: Create a Dynamic action to through Error when entering wrong date format.
var date_from = $v(‘P6_FROM_DATE’);
if(validateDate(date_from)== 0) {
apex.message.clearErrors();
if ( $(“#P6_FROM_DATE_error”).length == 0) {
apex.message.showErrors([
{
type: “error”,
location: [ “page”, “inline” ],
pageItem: “P6_FROM_DATE”,
