Answer 3

提交后刷新默认又提交了一次！
提交后最后重新加载页面：response.redirect

Answer 4

能否用其他方式.
請用代碼明示
Response.Redirect("index.aspx?");效果不是很好

Answer 5

ClientScript.RegisterStartupScript
改成
clientscript.RegisterClientScriptBlock
试一下

Answer 6

this.ClientScript.RegisterStartupScript(this.GetType(), "", "alert('庫位不符合!'); window.location.href = window.location.href;", true);
