我需要在没有ajax的Submit按钮上放置一个负载微调器。在ajax调用部分中,微调器已经设置好。这可能吗?

在此处查看示例:http://jsfiddle.net/gfh1op36/1/
您可以添加loader.gif图片
CSS:
/* Start by setting display:none to make this hidden.
Then we position it in relation to the viewport window
with position:fixed. Width, height, top and left speak
speak for themselves. Background we set to 80% white with
our animation centered, and no-repeating */
.modal {
display: none;
position: fixed;
z-index: 1000;
top: 0;
left: 0;
height: 100%;
width: 100%;
background: rgba( 255, 255, 255, .8 )
url('http://i.stack.imgur.com/FhHRx.gif')
50% 50%
no-repeat;
}
/* When the body has the loading class, we turn
the scrollbar off with overflow:hidden */
body.loading {
overflow: hidden;
}
/* Anytime the body has the loading class, our
modal element will be visible */
body.loading .modal {
display: block;
}
HTML:
