post back url + eval（）函数 [英] post back url + eval() function

问题描述

嗨小伙伴们



i希望将我的页面重定向到另一个页面并使用PostBackURL发送查询字符串，但它不起作用plz help :)

< asp：ImageButton ID =   ImageButton2 PostBackUrl = '  Mng.aspx？fileOutIdBook =<％＃Eval（fileOuId） ％>>& module = DeletFile' runat =   server /> ; 
 

i在我的地址栏中得到类似下面的内容 - >





http：// localhost：9965 / liberary / Mng / Mng.aspx？fileOutIdBook =％3C％#Eval％28％22fileOuId％22％29％20 %% 3E％3E& amp ; module = DeletFile



i预计会看到这个





http： //localhost:9965/liberary/Mng/Mng.aspx?fileOutIdBook=201&module=DeletFile



201由Eval（）

解决方案

尝试使用

 PostBackUrl ='< ;％＃字符串 .Format（  〜/ Mng.aspx？fileOutIdBook = {0}& module = DeletFile，Eval（  fileOuId ））％>'

请试试这个....



PostBackUrl ='Mng.aspx？fileOutIdBook ='<％＃ Eval（fileOuId）％>'&module = DeletFile'

似乎您遇到语法错误。所有内联表达式必须在打开和实际内容之间有一个whitesapce：

 <   asp：imagebutton     id   =  ImageButton2    postbackurl   =  Mng.aspx？fileOutIdBook = <％＃[此处必须有空格] Eval（  fileOuId）％>>& ; module = DeletFile    runat   =   server    xmlns：asp   = ＃unknown    /  >

hi guys

i want to redirect my page to another page and send query string with PostBackURL but it doesn't work plz help :)

<asp:ImageButton ID="ImageButton2" PostBackUrl='Mng.aspx?fileOutIdBook=<%#Eval("fileOuId") %>>&module=DeletFile' runat="server"/>

i get something like below in my address bar ->


http://localhost:9965/liberary/Mng/Mng.aspx?fileOutIdBook=%3C%#Eval%28%22fileOuId%22%29%20%%3E%3E&module=DeletFile

i expected to see this


http://localhost:9965/liberary/Mng/Mng.aspx?fileOutIdBook=201&module=DeletFile

201 bounded by Eval()

解决方案

try with

PostBackUrl='<%# String.Format("~/Mng.aspx?fileOutIdBook={0}&module=DeletFile", Eval("fileOuId")) %>'

pls try this one....

PostBackUrl='Mng.aspx?fileOutIdBook='<%#Eval("fileOuId") %>'&module=DeletFile'

It seems you got a syntax error. All inline expressions must have a whitesapce between opening and the actual content:

<asp:imagebutton id="ImageButton2" postbackurl="Mng.aspx?fileOutIdBook=<%#[here must have a whitespace]Eval("fileOuId") %>>&module=DeletFile" runat="server" xmlns:asp="#unknown" />
