Answer 1

尝试：

Page.ClientScript

而是看看它是否有所作为。

Answer 2

对于cs文件，示例是；

ClientScript.RegisterClientScriptBlock(this.GetType(), "{some text for type}", "alert('{Text come to here}'); ", true);

对于masterpage cs，示例是；

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "{some text for type}", "alert('{Text come to here}'); ", true);

Answer 3

在母版页上尝试ScriptManager.RegisterStartupScript()。请注意，签名与 . 略有不同Page.ClientScript.RegisterClientScriptBlock()。
