Select 关注同一类的输入，但一次只影响一个

当我在具有相同类的输入上单击（聚焦）/单击（模糊）时，我想做一个操作，但是我单击的输入应该受到影响，而不是像我在这里的示例中那样受到影响 **单击输入，现在显示所有描述。我只想显示我单击的输入的描述

<div class="form-wrapper">
    <div class="form-element ">
        <input type="email" name="email" id="email" value="" autofocus="autofocus" tabindex="1">
        <p class="description">First's input description!</p>
    </div>
</div> 
<div class="form-wrapper">
    <div class="form-element ">
        <input type="email" name="email" id="email" value="" autofocus="autofocus" tabindex="1">
        <p class="description">Second's input description!</p>
    </div>
</div>  
<div class="form-wrapper">
    <div class="form-element ">
        <input type="email" name="email" id="email" value="" autofocus="autofocus" tabindex="1">
        <p class="description">Third's input description!</p>
    </div>
</div>
<div class="form-wrapper">
    <div class="form-element ">
        <input type="email" name="email" id="email" value="" autofocus="autofocus" tabindex="1">
        <p class="description">Forth's input description!</p>
    </div>
</div>

谢谢

所以只需获取父el：

$$('.form-element > input').addEvents({
    focus: function () {
        this.getParent('.form-element').addClass('form_element_active')
    },
    blur: function () {
        this.getParent('.form-element').removeClass('form_element_active');
    }
});

谢谢，这正是我想要的。

$$('.form-element > input').addEvents({
    focus: function () {
        this.getParent('.form-element').addClass('form_element_active')
    },
    blur: function () {
        this.getParent('.form-element').removeClass('form_element_active');
    }
});
