SharePoint:ScriptLink測試

最終結論：

<SharePoint:ScriptLink  ID="SPlink1"  Name="sp.ui.tgportal.js"   Defer="false"  runat="server" OnDemand="false" Localizable="true" />

defer：	決定是否及時輸出，預設為“false”，“true”為最後輸出；
OnDemand：	決定是否由“RegisterSod”進行註冊，如果使用註冊，則頁面載入完後不馬上載入js，而是在調用函數前要進行載入，比如使用SP.SOD.executeFunc("sp.ui.tgportal.js", null, alert(0));
Localizable:	決定是否要在2052中尋找js，false是直接在layouts中尋找；
LoadAfterUI：	決定在head中輸出還是在body完成前

         Sharepoint JS CSS 註冊

2011-12-30添加

SharePoint:ScriptLink在內部調用的也是  ClientScript.RegisterStartupScript RegisterClientScriptBlock RegisterClientScriptInclude

通過js路徑來判斷是否未重複註冊

page2.ClientScript.RegisterStartupScript(typeof(ScriptLink), str, info.ToScriptBlock(page));

str = ExtractFilename(name) + localizable.ToString();
