1.
function addVidToForm($form) {
var ptData = Cookies.get('pt_16d8b331');
var cookieVid = ptData.match(/vid=([a-zA-Z0-9-_/]*)&/);
var vid = cookieVid[1];
$form.append('<input type="hidden" name="web_view_id" value="'+ vid +'">');
}
addVidToForm($('#sendform'));
2.放入jquery后面
<script src="//www.juwaistatic.com/frontend-libraries/js-cookie/2.1.0/js.cookie.min.js" type="text/javascript"></script>
