我想在表单提交后显示一个简单的加载图标。我的代码无法正确显示加载图标。您会发现,我为gif图像设置了visibility:hidden
。
<script src="js/jquery-1.11.1.min.js"></script>
<div class="" style="width: 480px; margin: 0 auto; margin-top: 20px;" id="form_wrapper">
<img src="img/loader.gif" id="gif" style="display: block; margin: 0 auto; width: 100px; visibility: hidden;">
<div class="fade" id="form">
<form action="process_login.php" method="POST" name="simplelogin" id="login_form"><br />
<label for="username"> Username:</label>
<input type="username" name="username" id="username" size="30" required><br><br>
<label for="password"> Password:</label>
<input type="password" name="password" id="password" size="30" required><br><br>
<input class="load_button" type="submit" name="submit" id="submit" value="Submit" placeholder="Submit">
</form>
</div>
</div>
<div class="fifty"></div>
<script type="text/javascript">
$('.load_button').submit(function() {
$('#gif').show();
return true;
});
</script>
