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');
}
});
});
