ClientScriptManager 类用于管理客户端脚本并将它们添加到 Web 应用程序中。可以从 Page 对象的 ClientScript 属性获取对 ClientScriptManager 类的引用。
程序源代码：ClientScriptManager.rar
向客户端添加脚本:
/**//// <summary>
/// 向客户端添加脚本 /// </summary> /// <param name="page">要添加脚本的页面</param> /// <param name="csName">标识脚本的键</param>
/// <param name="csText">脚本内容</param>
public void RegisterClientScriptBlock(Page page,string csName,string csText) 
{ ClientScriptManager cs = page.ClientScript; Type cstype = page.GetType(); if (!cs.IsClientScriptBlockRegistered(cstype, csName))
{ cs.RegisterClientScriptBlock(cstype, csName, csText, true);
} }例如：
protected void Page_Load(object sender, EventArgs e) { ScriptManager scriptManager = new ScriptManager(); scriptManager.RegisterClientScriptBlock(this, "TestAlert", "alert('测试 alert !');"); }向客户端添加数组：
/**//// <summary> /// 使用数组名称和数组值向 Page 对象注册 JavaScript 数组声明。 /// </summary> /// <param name="page">添加脚本的页面</param> /// <param name="arrayName">数组名称</param> /// <param name="array">数组值</param> public void RegisterArrayDeclaration(Page page, string arrayName, Array array) { StringBuilder sbArrayValue=new StringBuilder(); for (int i = 0; i < array.Length; i++) { if (i != 0) { sbArrayValue.Append(",\""+array.GetValue(i).ToString()+"\""); } else { sbArrayValue.Append("\"" + array.GetValue(i).ToString() + "\""); } } ClientScriptManager cs = page.ClientScript; cs.RegisterArrayDeclaration(arrayName, sbArrayValue.ToString()); }例如：
protected void Page_Load(object sender, EventArgs e) { string arrayName = "testArray"; int[] array ={1,2,3 }; ScriptManager scriptManager = new ScriptManager(); scriptManager.RegisterArrayDeclaration(this, arrayName, array); StringBuilder csText = new StringBuilder(); csText.Append("function doSum() {"); csText.Append("var arrSum="); csText.Append("parseInt(" + arrayName + "[0])+"); csText.Append("parseInt(" + arrayName + "[1])+"); csText.Append("parseInt(" + arrayName + "[2]);"); csText.Append("alert(arrSum);"); csText.Append("}"); scriptManager.RegisterClientScriptBlock(this, "Sum", csText.ToString()); btnDoSum.OnClientClick = "doSum(); return false"; }添加客户端脚本包含：
/**//// <summary> /// 使用键和 URL 向 Page 对象注册客户端脚本包含。 /// </summary> /// <param name="page">添加脚本的页面</param> /// <param name="includeName">要注册的客户端脚本包含的键。 </param> /// <param name="url">要注册的客户端脚本包含的 URL。</param> public void RegisterClientScriptInclude(Page page, string includeName, string url) { ClientScriptManager cs = page.ClientScript; cs.RegisterClientScriptInclude(includeName, url); }例如：
protected void Page_Load(object sender, EventArgs e) { ScriptManager scriptManager = new ScriptManager(); scriptManager.RegisterClientScriptInclude(this, "testInclude", "JScript.js"); }
