RegisterStartupScript和RegisterClientScriptBlock输出位置的区别.

 Page.Response.Write("<script>var response;</script>");

   Page.RegisterStartupScript("RegisterStartupScript","<script>var RegisterStartupScript;</script>");

   Page.RegisterClientScriptBlock("RegisterClientScriptBlock","<script>var RegisterClientScriptBlock;</script>");

Response.Write输出后的位置在源文件的第一行.

RegisterStartupScript输出后的位置会在<form>的下一行(在asp.net自带的脚本和一些隐藏域之下).

RegisterClientScriptBlock输出后的位置会在</form>的上一行.
