我需要验证输入字段,如文本,电子邮件,广播,复选框,选择。让我说我有这个:

<fieldset>
    <div class="form-top">
         <div class="form-bottom">
              <div class="form-group">
                   <label class="sr-only" for="form-first-name">First name</label>
                   <input type="text" name="form-first-name" placeholder="First name..." class="form-first-name form-control" id="form-first-name">
              </div>
              <div class="form-group">
                   <label class="sr-only" for="form-last-name">Last name</label>
                   <input type="text" name="form-last-name" placeholder="Last name..." class="form-last-name form-control" id="form-last-name">
              </div>
              <div class="form-group">
                   <input type="radio" name="gender" value="male"> Male<br>
                   <input type="radio" name="gender" value="female"> Female<br>
                   <input type="radio" name="gender" value="other"> Other  
              </div>
                   <div class="form-group">
                   <label class="sr-only" for="form-about-yourself">About yourself</label>
                   <textarea name="form-about-yourself" placeholder="About yourself..." class="form-about-yourself form-control" id="form-about-yourself"></textarea>
                   </div>
                   <button type="button" class="btn btn-next">Next</button>
        </div>
</fieldset>

在jQuery中,我用它来验证:

$('.registration-form .btn-next').on('click', function() {
        var parent_fieldset = $(this).parents('fieldset');
        console.log(parent_fieldset);
        var next_step = true;

        parent_fieldset.find('input[type="text"], input[type="radio"], input[type="password"], textarea').each(function() {
            if( $(this).val() == "" ) {
                $(this).addClass('input-error');
                next_step = false;
            }
            else {
                $(this).removeClass('input-error');
            }
        });

输入类型= text和textarea验证正在运行,但输入类型=无线电。有什么想法吗?

更新1 我正在使用多步骤表单,我使用此example,在此示例中,我在第一步中添加了

<div class="form-group">
     <input type="radio" name="gender" value="male"> Male<br>
     <input type="radio" name="gender" value="female"> Female<br>
     <input type="radio" name="gender" value="other"> Other  
</div>

答案 0 :(得分:1)

请不要检查($this).val()您要检查的电台:

($this).find(":selected").text();

一个小例子:

$('.btn').on('click', function() {
  $("input[type='radio']").each(function() { 
  	var radioName= $(this).attr('name'); 
    var isChecked =$("input[name='"+radioName+"']:checked").val();
    
    if( $(this).val() != "" && isChecked){ 
      $("#result").html('success');
    } 
    else { 
      $("#result").html('error');
    }  
  });
});
