JAVASCRIPT代码

(function($) {

  // Smooth scrolling using jQuery easing
  $('a.js-scroll-trigger[href*="#"]:not([href="#"])').click(function() {
    if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
      if (target.length) {
        $('html, body').animate({
          scrollTop: (target.offset().top - 48)
        }, 1000, "easeInOutExpo");
        return false;
      }
    }
  });

  // Closes responsive menu when a scroll trigger link is clicked
  $('.js-scroll-trigger').click(function() {
    $('.navbar-collapse').collapse('hide');
  });

  // Activate scrollspy to add active class to navbar items on scroll
  $('body').scrollspy({
    target: '#mainNav',
    offset: 48
  });

  // Collapse the navbar when page is scrolled
  $(window).scroll(function() {
    if ($("#mainNav").offset().top > 100) {
      $("#mainNav").addClass("navbar-shrink");
    } else {
      $("#mainNav").removeClass("navbar-shrink");
    }
  });

  // Scroll reveal calls
  window.sr = ScrollReveal();
  sr.reveal('.sr-icons', {
    duration: 600,
    scale: 0.3,
    distance: '0px'
  }, 200);

    duration: 1000,
    delay: 200
  });
  sr.reveal('.sr-contact', {
    duration: 600,
    scale: 0.3,
    distance: '0px'
  }, 300);

  // Magnific popup calls
  $('.popup-gallery').magnificPopup({
    delegate: 'a',
    type: 'image',
    tLoading: 'Loading image #%curr%...',
    mainClass: 'mfp-img-mobile',
    gallery: {

问题：正如你可以看到我的PHP，JS，HTML代码的联系表格，但由于某种原因，它不起作用!! ??每次我尝试使用它我一直得到（方法不允许）!!! ??我最努力的一切（新的PHP代码不同的HTML代码）和注意（我在故障上托管的网站上使用它）它没有正式支持PHP，但确实如此。

Answer 1

我试过你的代码。它应该工作，除了它应该是$body而不是body中的mail($to, $about, body, "From: $name <$email>");。

所以问题应该来自主机提供商。

BTW：Gmail似乎有更严格的安全策略。我在Gmail上失败并尝试了其他邮件服务并成功接收了该电子邮件。
