通过ajaxsubmit for contact表单执行php邮件功能，无需重定向到php文件

function contactForm(){
	function e(e){
		var t=/^([a-zA-Z0-9_.+-])+'@(([a-zA-Z0-9-])+'.)+([a-zA-Z0-9]{2,4})+$/;
		return t.test(e)
	}
	$(".js-contact-form").submit(function(){
		$(this).ajaxSubmit({
			data:{
				email:$(".js-contact-email").text().replace(/('r'n|'n| 'r)/gm,"").replace(/'s+/g," "),
				user_message:$(".js-mail-message").text().replace(/('r'n| 'n|'r)/gm,"").replace(/'s+/g," ")
				},
			beforeSubmit:function(t,n,r){
				var i=$(".js-contact-email"),s=$(".js-contact-name"),o= $(".js-contact-subject"),u=$(".js-contact-brief"),a=1;
					i.removeClass("js-error");s.removeClass("js- error");o.removeClass("js-error");u.removeClass("js-error");
					if(i.text()===i.data("placeholder")){i.addClass ("js-error");a=0}else if(!e(i.text())){i.addClass("js-error");a=0}if(s.text()===s.data ("placeholder")){s.addClass("js-error");a=0}if(o.text()===o.data("placeholder")) {o.addClass("js-error");a=0}if(u.text()===u.data("placeholder")){u.addClass("js- error");a=0}if(!a)return!1},
			success:function(e){
				$(".js-mail-message").addClass("js-hidden");
				$(".js-contact-submit").addClass("js-hidden");
				$(".js-mail-success").removeClass("js-hidden")
			}
		});return!1})
}

现在发生的是输入所有字段后，将显示消息（谢谢。我们已收到您的消息，并将很快与您联系。

）当未输入任何字段时，文本将显示为红色。以上所有的事情都必须按原样进行邮件也应该起作用。假设我在phpurl.php文件中有php邮件函数代码，然后如何留在联系人表单页面上使邮件部分在不将页面重定向到phpurl.php的情况下进行。

$(".js-contact-form").submit(function(e) {
    e.preventDefault();
    $.ajax({
        type:'POST', 
        url: 'php/secure-email.php', 
        data:$('#contactform').serialize(), 
        success: function(response) {
            $(".js-mail-message").addClass("js-hidden");
            $(".js-contact-submit").addClass("js-hidden");
            $(".js-mail-success").removeClass("js-hidden");
        },
        complete:function() {
            $('#contactform').each(function() {
                this.reset();
            });
        }
    });
});
