Microsoft VBScript运行时错误'800a000d'

Microsoft VBScript runtime error '800a000d'

类型不匹配:'[string:"]'

Type mismatch: '[string: ""]'

/FLPM/cp/images.cs.asp，第91行

/FLPM/cp/images.cs.asp, line 91

我尝试使用以下代码修复它，但仍然出现相同的错误.

I tried to fix it with the following codes but still get the same error.

PAGEID = Request.QueryString("PAGEID")

If PAGEID = "" or PAGEID = NULL or PAGEID = 0 Then
    PAGEID = 1
End If

推荐答案

if IsNumeric(pageId) and pageId <> "" then
  pageId = Cint(pageId)
else
  pageId = 1
end if

这将在接受它之前检查pageId是否具有值并且是数字值.

this will check if the pageId has a value and is a numeric value, before accepting it..
