画面刷新问题
两个画面(1.aspx,2.aspx)
1.aspx画面中有400个textbox
现在我在1.aspx中间第100个textbox旁边加一个button,用showdialog弹出2.aspx
在2.aspx中选取值后把值传回1.aspx中的第100个textbox
问题是虽然成功把值获得,但是焦点不在第100个textbox
1.aspx又会重新刷新画面?这是怎么回事?
1.aspx     pageload   写
Dim   openwinStr   As   String   =   " <script> "   +   vbCrLf
openwinStr   +=   "function   openWin()   { "   +   vbCrLf
openwinStr   +=   "var   url   =   '2.aspx ' "   +   "; "   +   vbCrLf
openwinStr   +=   "var   ret   =   window.showModalDialog(url); "   +   vbCrLf
openwinStr   +=   "if   (ret   !=   null)   { "   +   vbCrLf
openwinStr   +=   "   document.all.TextBox100.value=   ret "
openwinStr   +=   "} "   +   vbCrLf
openwinStr   +=   " </script> "   +   vbCrLf
Page.ClientScript.RegisterClientScriptBlock(Me.GetType,   "clientScript ",   openwinStr)
Button1.Attributes.Add( "onclick ",   "openWin() ")

2.aspx中   pageload
Dim   scriptStr   As   String   =   " <script> "   +   vbCrLf
scriptStr   +=   "function   reutrnValue()   { "   +   vbCrLf
  scriptStr   +=   "   var   ret   =document.all.TextBox1.value   "   +   vbCrLf
scriptStr   +=   "   window.returnValue=ret "   +   vbCrLf
scriptStr   +=   "   window.close() "   +   vbCrLf
scriptStr   +=   "} "   +   vbCrLf
scriptStr   +=   " </script> "


我写了js脚本后,虽然焦点设置了,但是1.aspx还是会自动刷新,焦点就没了
是不是我写在pageload的原因?

------解决方案--------------------
function openWin() 最后加上return false;

或者你加个html button, 不是服务端的button, 然后加onclick= "openWin(); "
