Hi Anthony,
This solution you mention is, with some minor changes, still working in the
current version. I've managed to get the change working in the 2.12.3
version of web2py.js:
Change function trap_form to:
trap_form: function(action, target) {
/* traps any LOADed form */
$('#' + target + ' form').each(function(i) {
var form = $(this);
if(form.hasClass('no_trap')) {
return;
}
form.attr('data-w2p_target', target);
var url = form.attr('action');
if((url === "") || (url === "#") || (typeof url === 'undefined'))
{
/* form has no action. Use component url. */
url = action;
}
/* begin change */
if(form.find('.upload').length>0) {
form.ajaxForm({
url: url,
success: function(data, statusText, xhr) {
jQuery('#'+target).html(xhr.responseText);
web2py.trap_form(action, target);
web2py.ajax_init();
}
});
} else { /* end change */
form.submit(function(e) {
web2py.disableElement(form.find(web2py.formInputClickSelector));
web2py.hide_flash();
web2py.ajax_page('post', url, form.serialize(), target, form);
e.preventDefault();
});
};
form.on('click', web2py.formInputClickSelector, function(e) {
e.preventDefault();
var input_name = $(this).attr('name');
if(input_name != undefined) {
$('<input type="hidden" />').attr('name', input_name)
.attr('value', $(this).val()).appendTo(form)
}
form.trigger('submit');
});
});
},
Regards,
Bart
