Check if inputs form are empty jQuery
var empty = true;$('input[type="text"]').each(function() { if ($(this).val() != "") { empty = false; return false; }});This should look all the input and set the empty var to false, if at least one is not empty.
EDIT:
To match the OP edit request, this can be used to filter input based on name substring.
$('input[name*="denominationcomune_"]').each(...
You could do it like this :
bool areFieldEmpty = YES;//Label to leave the loopsouter_loop;//For each input (except of submit) in your form$('form input[type!=submit]').each(function(){ //If the field's empty if($(this).val() != '') { //Mark it areFieldEmpty = NO; //Then leave all the loops break outer_loop; }});//Then test your bool
You can do it using simple jQuery loop.
