但是后来发现在使用asp.net编程时，如果应用模板页的话，不止是css文件不容易后往里添，javascript文件也是如此，虽然说在模板页的<head />中建一个contentplaceholder也算可以，但那种方法毕竟不太雅，有失风范。于是就想按这种添加<link />标签的方法来泡制<script />
但发现在System.Web.UI.HtmlControls中有HtmlLink来表现<link />但却没有表现<Script />标签的类。
没办法了，因为懒所以只能自己写一个了，代码不长，如下。
namespace Chsword.Class {
/// <summary>
/// 可以生成script标签
/// </summary>
[ControlBuilder(typeof(HtmlEmptyTagControlBuilder)), AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal), AspNetHostingPermission(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class HtmlScript : HtmlControl {
// Methods
public HtmlScript()
: base("script") {
}
protected override void Render(HtmlTextWriter writer) {
writer.WriteBeginTag(this.TagName);
this.RenderAttributes(writer);
writer.Write(">");
writer.WriteEndTag(TagName);
}
protected override void RenderAttributes(HtmlTextWriter writer) {
if (!string.IsNullOrEmpty(this.Src)) {
base.Attributes["src"] = base.ResolveClientUrl(this.Src);
}
base.Attributes["type"] = "text/javascript";
base.RenderAttributes(writer);
}
/// <summary>
/// 脚本的URL
/// </summary>
[UrlProperty]
[DefaultValue("")]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public virtual string Src {
get {
string text = base.Attributes["src"];
if (text == null) {
return string.Empty;
}
return text;
}
set {
base.Attributes["src"] = MapStringAttributeToString(value);
}
}
string MapStringAttributeToString(string s) {
if ((s != null) && (s.Length == 0)) {
return null;
}
return s;
}
}
}
/// <summary>

public class HtmlScript : HtmlControl {

}
protected override void Render(HtmlTextWriter writer) {
writer.WriteBeginTag(this.TagName);
this.RenderAttributes(writer);
writer.Write(">");
writer.WriteEndTag(TagName);
}
protected override void RenderAttributes(HtmlTextWriter writer) {
if (!string.IsNullOrEmpty(this.Src)) {
base.Attributes["src"] = base.ResolveClientUrl(this.Src);
}
base.Attributes["type"] = "text/javascript";
base.RenderAttributes(writer);
}

}
}
string MapStringAttributeToString(string s) {
if ((s != null) && (s.Length == 0)) {
return null;
}
return s;
}
}
}
/// <summary>
/// 设置script现在只能是type=text/javsscript的
/// </summary>
/// <param name="src">脚本地址</param>
protected void SetHtmlScript(string src) {
HtmlScript myHtmlScript = new HtmlScript();
myHtmlScript.Src = src;
Page.Header.Controls.Add(myHtmlScript);
}
/// 设置script现在只能是type=text/javsscript的
/// </summary>

protected void SetHtmlScript(string src) {

Page.Header.Controls.Add(myHtmlScript);
}
使用方法
原来的页面脚本是这样的
vb.net
Partial Class Default
Inherits Page现在只要改成
Partial Class Default Inherits ChPage就可以了
使用时只要在载入前的某个事件，比如Init或Load写 SetHtmlScript("/Javascript/MicrosoftAjax.js")
这样就OK了
直接再看看生成的HTML，吼吼，已经有你添加的<script src=""/Javascript/MicrosoftAjax.js" type="text/javascript"></script>了
