本文实例讲述了jQuery实现按钮点击遮罩加载及处理完后恢复的效果。分享给大家供大家参考，具体如下：
运行效果图如下：
具体代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="EasyUiLoad.aspx.cs" Inherits="EasyUiLoad" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>EasyUI加载效果</title> <style type="text/css"> body{font-size:12px} .datagrid-mask{position:absolute;left:0;top:0;width:100%;height:100%;opacity:.5;filter:alpha(opacity=30);background-color:#e0ecff;display:none} .datagrid-mask-msg{position:absolute;top:50%;margin-top:-20px;padding:10px 15px 10px 15px;width:auto;height:16px;border-width:2px;border-color:#68a5ff;border-style:solid;display:none} .img1{vertical-align:middle;} </style> <script src="JS/jquery-1.9.1.js" type="text/javascript"></script> <script type="text/javascript"> //load function EasyUILoad() { $("<div></div>").css({ display: "block", width: "100%", height: "auto !important" }).appendTo("body"); $("<div></div>").html("<img src='images/loading.gif' /> 正在运行，请稍候。。。").appendTo("body").css({ display: "block", left: ($(document.body).outerWidth(true) - 190) / 2, top: ($(window).height() - 45) / 2 }); } //display Load function dispalyEasyUILoad() { $(".datagrid-mask").remove(); $(".datagrid-mask-msg").remove(); } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="加载效果" OnClientClick="javascript:EasyUILoad();" /> </div> </form> </body> </html>
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class EasyUiLoad : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { System.Threading.Thread.Sleep(5000); //处理逻辑... //完成处理后恢复 ClientScript.RegisterStartupScript(this.GetType(), "closeLoad", "dispalyEasyUILoad();", true); } }
希望本文所述对大家jQuery程序设计有所帮助。
