Forms Designer Forum

Hi,

I am trying to add an alert if a Multiple lines of text (Enhanced rich text) is empty.

I found these solutions in the forum but nothing work.

if ($(fd.field('FieldName').value()).text() == "")
if(!fd.field('FieldName').control()._el().find('div.ms-rtestate-write').text().replace(/\W/g, ''))

Can you help me

var error = false;

function checkFields(){

setRedSingleERT('AnswerEnglish');
}
}

function setRedSingleERT(fieldname){
$('.fd_field[fd_name='+fieldname+'] .ms-inputBox').css(

if (self.text){
self.css(
{'border-color': ''})
}
});
error = true;

fd.onsubmit(function(){
checkFields();
if(!error){
