loading 功能实现(遮罩)

1. loading 样式图标可以从网站定制： https://loading.io/

2. css 样式：

@keyframes lds-spinner {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}

@-webkit-keyframes lds-spinner {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}
.lds-css {
	position:fixed; 
	top:0;
	width: 100%; 
	height: 100%;
	background-color: #eeeeee;
	z-index:9999;
	filter:alpha(Opacity=80);-moz-opacity:0.5;opacity: 0.5;
