在调试ajaxpro结合gridview的时候，出现了奇怪的函数调用的问题
代码如下
using system;
using system.data;
using system.configuration;
using system.collections;
using system.web;
using system.web.security;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.webcontrols.webparts;
using system.web.ui.htmlcontrols;
using system.data.sqlclient;
namespace loadgridview
{
public partial class default6 : system.web.ui.page
{
protected void page_load（object sender, eventargs e)
{
ajaxpro.utility.registertypeforajax（typeof（default6));
}
[ajaxpro.ajaxmethod]
public int addajaxtable（string name)
{
string strcon = "server=.;database=ajaxtable;uid=sa;pwd=lanjie ";
sqlconnection con = new sqlconnection（strcon);
con.open（);
sqlcommand com = new sqlcommand（);
com.commandtext = "insert into ajaxtt values（ ' " + name + " ') ";
com.connection = con;
int result=com.ＥＸＥＣutenonquery（);
con.close（);
com.dispose（);
return result;
}
[ajaxpro.ajaxmethod]
public string getajaxtable（int a )
{
string strcon = "server=.;database=ajaxtable;uid=sa;pwd=lanjie ";
sqlconnection con = new sqlconnection（strcon);
con.open（);
sqlcommand com = new sqlcommand（);
com.commandtext = "select * from ajaxtt ";
com.connection = con;
sqldataadapter dra = new sqldataadapter（);
dra.selectcommand = com;
dataset ds = new dataset（);
dra.fill（ds, "ajaxtt ");
con.close（);
com.dispose（);
gridview gv = new gridview（);
gv.datasource = ds;
gv.databind（);
system.text.stringbuilder strb = new system.text.stringbuilder（);
system.io.stringwriter sw = new system.io.stringwriter（strb);
system.web.ui.htmltextwriter htw = new system.web.ui.htmltextwriter（sw);
gv.rendercontrol（htw);
string s = strb.tostring（);
return s;
}
}
}
<%@ page language= "c# " autoeventwireup= "true " codefile= "default6.aspx.cs " inherits= "loadgridview.default6 " %>

<script language=javascript>
function addajax（)
{
var name=document.getelementbyid（ "nametext ").value;
loadgridview.default6.addajaxtable（name,callback);
// loadgv（);
}
function loadgv（)
{
loadgridview.default6.getajaxtable（1,callserverback);
}
function callserverback（res)
{
var cc=document.getelementbyid（ "gv ");
cc.innerhtml=res.value;
}
function callback（ss)
{
if（ss.value!=0)
{
loadgv（);
}
}
</script>
</head>
<body onload= "loadgv（); ">
<form id= "form1 " runat= "server ">
<input type= "text " id= "nametext "/>
<input type= "button " value= "ajaxbutton " onclick= "addajax（); " />
<div id= "gv ">
</div>
</form>
</body>
</html>
这是出问题的代码，如果js代码改写成下面就可以了，
<script language=javascript>
function addajax（)
{
var name=document.getelementbyid（ "nametext ").value;
loadgridview.default6.addajaxtable（name);
loadgv（);
}
function loadgv（)
{
document.getelementbyid（ "nametext ").innerhtml=loadgridview.default6.getajaxtable（1).value;
}
</script>
那么这是怎么回事呢？ |
