jQuery / JS设置全局变量，但卡在传递给AJAX自定义函数

设法解决了，这是其他任何想知道的人的解决方案......只需要调用处理全局变量的 Ajax 函数

/* grab completed email when enetred into checkout and add to abandoned cart 
for that session */
function validEmail(v) {
    var r = new RegExp(/^(("['w-'s]+")|(['w-]+(?:'.['w-]+)*)|("['w-'s]+")(['w-]+(?:'.['w-]+)*))(@((?:['w-]+'.)*'w['w-]{0,66})'.([a-z]{2,6}(?:'.[a-z]{2})?)$)|(@'[?((25[0-5]'.|2[0-4][0-9]'.|1[0-9]{2}'.|[0-9]{1,2}'.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})'.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})']?$)/i);
    return (v.match(r) == null) ? false : true;
}
