html5对于表单验证提供了很多自识别功能，非常的便利。

看代码，

<!--head start-->

<include file="Public:head" />

<!-- style here  -->

<!--head end -->

<section class="panel">

    <div class="panel-body">

        <form role="form" id="myform" method="post" enctype="multipart/form-data">

            <input type="hidden" name="id" value="{$info.id}">

            <div class="form-group">

                <label for="">名称</label>

                <input type="text" name="name" class="form-control" id="name" placeholder="" value="{$info.name}" required>

            </div>

            <div class="form-group">

                <label for="">排序(数字大靠前)</label>

                <input type="number" name="sort" value="{$info.sort}" class="form-control" id="sort" placeholder="" required>

            </div>

            <div class="form-group">

                <label for="">拼音/英文</label>

                <input type="text" name="spell" class="form-control" id="spell" placeholder="" value="{$info.spell}" pattern="^[a-zA-Z]+$" required>

            </div>

            <button type="submit" class="btn btn-info">提交</button>

        </form>

    </div>

</section>

<!--foot start-->

<include file="Public:foot" />

<!--foot end -->

<!-- script here  -->

<script>

var index = parent.layer.getFrameIndex(window.name);

var handle_status = '{$handle_status}';

if ( handle_status == '1' ) {

    parent.$("#handle_status").val('1');

    parent.layer.close(index);

} else if ( handle_status == '2' ) {

    parent.$("#handle_status").val('2');

    parent.layer.close(index);

}

</script>
