SharePoint:ScriptLink测试

最终结论

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