JSF validate dialog form - ajax

Question

I have a dialog form popup when I click one button, this form is used to create a new school record with just one field.
I have add required validation to this only input field, and everything works fine, but the only thing I don't know how to do is when I click submit, whatever form validate or not, the dialog will dismiss by following code:
initDataTable();
// Dismiss the dialog
$('#dialogNewSchool').dialog('close');
before the dialog close, I should put the form validation check (something like the return from validation class), how I can do this in javascript? I'm using JSF 2.1 implementation.
Btw, I don't want to use client side validation, because not only required validation needed for this field.
Thanks. ;)

Answer 1

If I got you right you want to keep dialog open in case of validation errors?
Than you can add the following code somewhere in your page
<h:panelGroup id="global_flag_validation_failed_render">
<h:outputText id="global_flag_validation_failed" value="true" rendered="#{facesContext.validationFailed}"/>
</h:panelGroup>
And upon clicking your submit button render the above block like this:
<f:ajax onevent="closeMyDialogIfAllOk" render="#form global_flag_validation_failed_render"></f:ajax>
and in your js code
function closeMyDialogIfAllOk(data){
if(data.status === 'success') {
if($("#global_flag_validation_failed").length === 0){
$("#dialog_id").dialog("close");
}
}
}
