SharePoint:ScriptLink测试

wslhs

　　最终结论：
  
   
<SharePoint:ScriptLink  ID=&quot;SPlink1&quot;  Name=&quot;sp.ui.tgportal.js&quot;   Defer=&quot;false&quot;  runat=&quot;server&quot; OnDemand=&quot;false&quot; Localizable=&quot;true&quot; />

defer：	决定是否及时输出，默认为“false”，“true”为最后输出；
OnDemand：	决定是否由“RegisterSod”进行注册，如果使用注册，则页面加载完后不马上加载js，而是在调用函数前要进行加载，比如使用SP.SOD.executeFunc("sp.ui.tgportal.js", null, alert(0));
Localizable:	决定是否要在2052中查找js，false是直接在layouts中查找；
LoadAfterUI：	决定在head中输出还是在body完成前

　　Sharepoint JS CSS 注册
　　2011-12-30添加
　　SharePoint:ScriptLink在内部调用的也是  ClientScript.RegisterStartupScript RegisterClientScriptBlock RegisterClientScriptInclude
　　通过js路径来判断是否未重复注册
　　page2.ClientScript.RegisterStartupScript(typeof(ScriptLink), str, info.ToScriptBlock(page));
　　str = ExtractFilename(name) + localizable.ToString();
