ASP.NET----实现点击按钮或链接弹出登录对话框
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
主要是利用遮罩的原理：
<!--默認讓登陸窗體不顯示--><style type="text/css">
#login
{
position: relative;
}
</style>
<!--窗體不顯示執行結束-->
上述主要實現默認讓id=“login”登錄窗體隱藏
<!--點擊登陸時彈出隱藏的登陸窗體--><script type="text/javascript">
$(document).ready(function () { $("#yz").click(function () { $("div#login").show(); }); });
</script>
<!--腳本執行結束-->
以上主要是利用Jquery實現隱藏窗體的顯示,具體標簽大家自行命名,此處只為大概原理，當然還有很多好的方法代碼。
以下為收集而來的例子：
