jQuery表单验证与电子邮件检查功能

Question

我对JS / jQuery有点新，并且在页脚中有一个页面，其中有一个表单和一个全局表单，用于通讯，这似乎与电子邮件字段验证相混淆....我知道需要更改为什么解决这个问题，那就是将验证点击/电子邮件检查功能附加到元素父表单上，但是对于我的生活来说无法解决这个问题。

因此在shell中需要以下内容才能使用其父窗体，因为它似乎影响了使用相同验证的其他窗体。

$( document ).ready(function() {

  function validateEmail($email) {
    var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
    return emailReg.test( $email );
  }

  function inputReset(element) {
    if (element.hasClass('error')) {
      element.removeClass("error");
      element.siblings('.error-message').remove();
    }
  }

  // Validation
  $('.validate-form').on('click', function(event) {
      event.preventDefault();

      var valid = true,
          message = '';

      $('form.validate input').each(function() {
        var $this = $(this);
        inputReset($this); 

        if($this.prop('required')){

          // check for errors, if found lets get the messages for output
          if(!$this.val()) {
            $(this).addClass("error");
            var inputName = $this.attr('name');
            message = $this.data('error-message');
            valid = false;
          }

          // validate the email input
          if($(this).hasClass('validate-email')) {
            var emailAddress = $this.val();
            if(!validateEmail(emailAddress)) { 
              $this.addClass("error");
              valid = false;
            }
          }

          $('.error-message[data-input-name="' + inputName + '"]').remove();
          // if not validated lets display the errors
          if(!valid) {
            //alert(message);
            $this.after('<div class="error-message" data-input-name="' + inputName + '">' + message + '</div>');
          }

        }

      });

    if(valid) {
      $(".validate-form").submit();
    }

  });

});

我有想要添加到全局var

form = $(this).closest("form").attr('id')

我认为这是正确的方法....但猜测大声笑

页面表格：

您遇到的麻烦是因为您用来获取输入字段的jQuery选择器正在扫描整个页面。 他们应该只搜索相对于触发验证的表单的输入。

您可以获得最接近验证点击上下文的表单。请注意更改：

获取表格：

var form = $(this).closest("form");

在表单中搜索输入字段：

form.find('input').each(function() {

仅清除特定表单中的错误消息：

form.find('.error-message[data-input-name="' + inputName + '"]').remove();

只提交特定表格而不是两者：

 form.submit();

完全改变：

$('.validate-form').on('click', function(event) {
  event.preventDefault();
  var form = $(this).closest("form");
  var valid = true,
      message = '';

  form.find('input').each(function() {
    var $this = $(this);
    inputReset($this); 

    if($this.prop('required')){

      // check for errors, if found lets get the messages for output
      if(!$this.val()) {
        $(this).addClass("error");
        var inputName = $this.attr('name');
        message = $this.data('error-message');
        valid = false;
      }

      // validate the email input
      if($(this).hasClass('validate-email')) {
        var emailAddress = $this.val();
        if(!validateEmail(emailAddress)) { 
          $this.addClass("error");
          valid = false;
        }
      }

      form.find('.error-message[data-input-name="' + inputName + '"]').remove();
      // if not validated lets display the errors
      if(!valid) {
        //alert(message);
        $this.after('<div class="error-message" data-input-name="' + inputName + '">' + message + '</div>');
      }
    }
    });

  if(valid) {
    form.submit();
  }
});
