Question

при клике на кнопку формы мне нужно проверить текстовое поле на пустоту условием, если в поле пусто то не запускать модальное окошко fancybox

if($('#id') != ' '){$('#asd_subscribe_submit').click(function(){        setTimeout(function() {            $.fancybox.open({            type: 'ajax',            href: '/personal/why_we/kupon.html',            maxWidth:700,            maxHeight:530,            helpers : {            overlay : {            locked : false,            speedOut   : 0,            showEarly  : true            }}            });        }, 1000);    });}

Я вот так написал проверку но оно что-то не работает

if($('#id').val() != '')

 

 

Во первых надо проверять не на пробел, а на пустоту... Во вторых вы забыли получить значение и сравниваете селектор(но не его значение) с пробелом...
