本文实例讲述了jQuery实现的自定义弹出层效果。分享给大家供大家参考,具体如下:
dialog.css:
#DialogBySHFLayer { width:100%; height:100%; left:0; top:0; position:fixed; z-index:500; background-color:#333333; filter:alpha(Opacity=40); -moz-opacity:0.4; opacity: 0.4; } /*弹出的提示框*/ #DialogBySHF { position:absolute; border-radius:3px; box-shadow:0 0 8px rgba(0, 0, 0, .8); background-color:#f2f2f2; z-index:600; } #DialogBySHF #Title { margin:0; width:100%; height:35px; background-color:#ffa500; color:#FFFFFF; font-family: 'microsoft yahei'; font-size:18px; text-align:center; cursor:move; line-height:35px; border-radius:3px 3px 0 0; -moz-user-select:none; -webkit-user-select:none; user-select:none; } #DialogBySHF #Close { position:absolute; right:7px; top:6px; height:21px; line-height:21px; width:21px; cursor:pointer; display:block; border:1px solid #da8e02; box-shadow:0 0 4px rgba(255, 255, 255, .9); border-radius:3px; } #DialogBySHF #Container { padding:0px 5px 5px 5px; /*width:390px; height:355px;*/ } #DialogBySHF #Container table,#DialogBySHF #Container iframe { width:100%; height:100%; } #DialogBySHF #Container table td { vertical-align:middle; } #DialogBySHF #Container table #TipLine { padding:0 30px; font-family: 'microsoft yahei'; } #DialogBySHF #Container table #BtnLine { height:60px; text-align:center; } #DialogBySHF #Container table #BtnLine input { margin:6px 11px; -moz-user-select: none; background-color:#F5F5F5; background-image: -moz-linear-gradient(center top , #F5F5F5, #F1F1F1); background-image:-ms-linear-gradient(rgb(245, 245, 245), rgb(241, 241, 241)); background-image:-webkit-linear-gradient(top,#f8f8f8,#f1f1f1); border:1px solid rgba(0,0,0,0.1); *border:1px solid #DDDDDD; border:1px solid #DDDDDD\0; border-radius:2px; font-family: 'microsoft yahei'; color:#666666; cursor:default; font-size:12px; font-weight:bold; height:29px; line-height:27px; min-width:54px; padding:0 8px; text-align:center; } #DialogBySHF #Container table #BtnLine input:hover { background-color: #F8F8F8; background-image: -moz-linear-gradient(center top , #F8F8F8, #F1F1F1); border: 1px solid #C6C6C6; box-shadow: 0 1px 1px rgba(0, 0, 0, 0.1); color: #333333; } #DialogBySHF #Container table #BtnLine input:focus { border: 1px solid #4D90FE; outline: medium none; }
