Question

因为问题指定我希望填充的表单条目显示在表单下面的某处。我试图根据每个输入值构建一个字符串。但是点击提交按钮时没有显示任何内容，它只会滚动到页面顶部。

＆＃13;

$(function() {

  var $name = $("#name");
  var $email = $("#email");
  var $password = $("#password");
  var $mobile = $("#mobile");
  var $textarea = $("#textarea");
  var $filledHtml = "";

  $("form span").hide();

  function isEmailValid() {
    var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
    return emailReg.test($email.val());
  }

  function isPasswordValid() {
    return $password.val().length > 8;
  }

  function isMobileValid() {
    return $mobile.val().length === 10;
  }


  function canSubmit() {
    return isPasswordValid() && isEmailValid() && isMobileValid();
  }

  function passwordEvent() {

    if (isPasswordValid()) {

      $password.next().hide();
      $filledHtml += $password.val() + "<br />";
    } else {

      $password.next().show();
    }
  }

  function emailEvent() {

    if (isEmailValid()) {

      $email.next().hide();
      $filledHtml += $email.val() + "<br />";
    } else {

      $email.next().show();
    }
  }

  function mobileEvent() {

    if (isMobileValid()) {

      $mobile.next().hide();
      $filledHtml += $mobile.val() + "<br /> ";
    } else {

      $mobile.next().show();
    }
  }

  function enableSubmitEvent() {

    $("#submit").prop("disabled", !canSubmit());

  }



  $email.focus(emailEvent).keyup(emailEvent).keyup(enableSubmitEvent);

  $password.focus(passwordEvent).keyup(passwordEvent).keyup(enableSubmitEvent);

  $mobile.focus(mobileEvent).keyup(mobileEvent).keyup(enableSubmitEvent);

  enableSubmitEvent();

  $("#submit").click(function() {
    $filledHtml += $textarea.val();
    $('#filled-data').html(filledHtml).addClass('small');
  });



});

Answer 1

当您按下提交按钮时，会显示，但同时会发布到该页面。所以页面在技术上得到了刷新。因此，请添加return false或e.preventDefault()，以便它不会发布或刷新页面：

$("#submit").click(function(){
    $filledHtml += $textarea.val();
    $('#filled-data').html(filledHtml).addClass('small');
    return false;
});

稍后您可以使用$.post()或$.get()提交表单数据并将其显示在屏幕上。

另一个错误是，filledHtml不等于$filledHtml。忘了美元符号：

$("#submit").click(function() {
  $filledHtml += $textarea.val();
  debugger;
  $('#filled-data').html($filledHtml).addClass('small');
  //---------------------^ Add dollar here.
  return false;
});

在div中显示填充的表单字段
