Buon pomeriggio.C'è qualcuno che ha utilizzato il form FancySlidingForm, preso qui
http://javascript.html.it/script/ved...-sliding-form/ nell'archivio degli script di HTML?
Praticamente, devo eseguire dei controlli, sulle input file, checkbox, text che compongono il form.Purtroppo, lo script originale di questo FancySlidingForm, controlla tutte le input, se sono diverse da stringa vuota, allora cambia lo status da 'error' a 'checked'.
Però a me servirebbe eseguire il controllo solo su determinati input e non su tutti.
vi posto per intero lo script.
codice:
$(function() {
/*
number of fieldsets
*/
var fieldsetCount = $('#formElem').children().length;
/*
current position of fieldset / navigation link
*/
var current = 1;
/*
sum and save the widths of each one of the fieldsets
set the final sum as the total width of the steps element
*/
var stepsWidth = 0;
var widths = new Array();
$('#steps .step').each(function(i){
var $step = $(this);
widths[i] = stepsWidth;
stepsWidth += $step.width()+20;
});
$('#steps').width(stepsWidth);
/*
to avoid problems in IE, focus the first input of the form
*/
$('#formElem').children(':first').find(':input:first').focus();
/*
show the navigation bar
*/
$('#navigation').show();
/*
when clicking on a navigation link
the form slides to the corresponding fieldset
*/
$('#navigation a').bind('click',function(e){
var $this = $(this);
var prev = current;
$this.closest('ul').find('li').removeClass('selected');
$this.parent().addClass('selected');
/*
we store the position of the link
in the current variable
*/
current = $this.parent().index() + 1;
/*
animate / slide to the next or to the corresponding
fieldset. The order of the links in the navigation
is the order of the fieldsets.
Also, after sliding, we trigger the focus on the first
input element of the new fieldset
If we clicked on the last link (confirmation), then we validate
all the fieldsets, otherwise we validate the previous one
before the form slided
*/
$('#steps').stop().animate({
marginLeft: '-' + widths[current-1] + 'px'
},500,function(){
if(current == fieldsetCount)
validateSteps();
else
validateStep(prev);
$('#formElem').children(':nth-child('+ parseInt(current) +')').find(':input:first').focus();
});
e.preventDefault();
});
/*
clicking on the tab (on the last input of each fieldset), makes the form
slide to the next step
*/
$('#formElem > fieldset').each(function(){
var $fieldset = $(this);
$fieldset.children(':last').find(':input').keydown(function(e){
if (e.which == 9){
$('#navigation li:nth-child(' + (parseInt(current)+1) + ') a').click();
/* force the blur for validation */
$(this).blur();
e.preventDefault();
}
});
});
/*
validates errors on all the fieldsets
records if the Form has errors in $('#formElem').data()
*/
function validateSteps(){
var FormErrors = false;
for(var i = 1; i < fieldsetCount; ++i){
var error = validateStep(i);
if(error == -1)
FormErrors = true;
}
$('#formElem').data('errors',FormErrors);
}
/*
validates one fieldset
and returns -1 if errors found, or 1 if not
*/
function validateStep(step){
if(step == fieldsetCount) return;
var error = 1;
var hasError = false;
$('#formElem').children(':nth-child('+ parseInt(step) +')').find(':input:not(button)').each(function(){
var $this = $(this);
var valueLength = jQuery.trim($this.val()).length;
/*a questo punto, all'apertura del form lo status delle input sono vuote, colorandole di rosa altrimenti di bianco, se riempite.
A questo punto, vorrei inserire un controllo, solo su determinate input.
*/
if(valueLength == ''){
hasError = true;
$this.css('background-color','#FFEDEF');//colore rosa
}
else
$this.css('background-color','#FFFFFF');//colore bianco
});
var $link = $('#navigation li:nth-child(' + parseInt(step) + ') a');
$link.parent().find('.error,.checked').remove();
var valclass = 'checked';
if(hasError){
error = -1;
valclass = 'error';
}
$('<span class="'+valclass+'"></span>').insertAfter($link);
return error;
}
/*
if there are errors don't allow the user to submit
*/
$(document).ready(function() {
$('#registerButton').bind('click',function(){
if($('#formElem').data('errors')){
return false;
});
});
Se vi può essere d'aiuto, posto anche la pagina dov'è il form.
Aiutooooooo....
