Question

我有这个表格有很多验证。

我正在努力的是，当所有字段都填写正确后，我希望字段的值显示在警告框中。

这是我的代码

<form method="post" name="form" id="form" class="form" action="">

            <div class="info  align-right"><span class="error">*</span> Required</div>

            <fieldset>
                <div class="group">
                    <label for="name">Name</label>
                    <input id="name" name="name" type="text" required />
                </div>

                <div class="group">
                    <label for="UserEmail">Email <span class="req">*</span></label>
                    <input type="text" name="UserEmail" id="UserEmail" value="" size="32" />
                </div>

                <div class="group">

                </div>
            </fieldset>

            <fieldset class="clearfix">
