本文實(shí)例講述了ASP.NET中常用輸出JS腳本的類，針對(duì)過(guò)去輸出js腳本的類進(jìn)行了一定的改進(jìn)。在項(xiàng)目開(kāi)發(fā)中非常具有實(shí)用價(jià)值。分享給大家供大家參考。具體如下：
很多時(shí)候在ASP.NET中我們經(jīng)常需要輸出一些JS腳本，比如彈出一個(gè)警告窗口，返回到歷史頁(yè)面等JS功能，我看到網(wǎng)上流傳得比較廣的是馬先光寫的一個(gè)JScript類，這個(gè)類基本將經(jīng)常用到的JS腳本包含了，非常方便，唯一的不足是作者采用的Response.Write(string msg)的辦法，這樣造成輸出的js腳本在<html></html>標(biāo)簽之外，破壞了原有XHTML的結(jié)構(gòu)，所以本人在滿足原功能的情況下，對(duì)JScript類做了進(jìn)一步的改善，這個(gè)改善采用了重載的辦法，增加了一個(gè)System.Web.UI.Page類的實(shí)例作為參數(shù)，不會(huì)影響原來(lái)的程序代碼。
整個(gè)程序的代碼如下：
代碼如下:using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI;
