我有两个输入字段和一个提交按钮(内联显示).输入字段填写完毕后,我尝试向下一个同级添加一个类.所以如果填写名字输入字段,请在电子邮件输入字段中添加一个类,如果电子邮件输入字段已填写,则将类添加到下一个输入字段等等…
这是我的代码到目前为止
$('.form-display #mce-FNAME').blur(function() {
if($.trim(this.value).length) {
$('#mce-EMAIL').toggleClass('animated pulse');
}else if(...){ }...
});
我的HTML看起来像这样：
<div class="form-display">
<div class="mc-field-group">
<label for="mce-FNAME">First Name </label>
<input type="text" value="" name="FNAME" class="" id="mce-FNAME">
</div>
<div class="mc-field-group">
<label for="mce-EMAIL">Email Address </label>
<input type="email" value="" name="EMAIL" class="required email" id="mce-EMAIL">
</div>
<input type="submit" value="Subscribe" name="subscribe" id="mc-embedded-subscribe" class="button">
</div>
解决方法
将除提交按钮之外的所有输入都收集到集合中.
在输入时,根据当前输入是否具有值来切换下一个输入的类：
var inputs = $('.form-display input').not(':submit');
inputs.on('input',function() {
$(inputs[inputs.index(this) + 1]).toggleClass('animated pulse',this.value > '');
});
片段：
var inputs = $('.form-display input').not(':submit'); //all inputs except submit button
inputs.on('input',this.value > '');
});
.animated.pulse {
background: yellow;
}
