如何在JavaScript中将返回的字符串数组从函数分配给varble

问题描述

在我的应用程序中，我在.cs文件中编写了一个返回字符串数组的函数，并在javascript部分中对该函数进行了调用.我必须获取这些返回的函数值并使用lable在对话框中显示使用ajax.我不明白如何在javascript.Olz中重新获得该值.

我写的代码如下.
holiday.aspx

< script language ="javascript" type ="text/javascript">
函数myfuncion(id){
var a = new Array();
a = HolidayApps.RetrieveData(id.toString());
document.getElementById("lblDesc").textContent = a [1] .value;
$(''#dialog'').dialog(''open'');
//alert(a.value);
}
$(function(){
//对话框
$(''#dialog'').dialog({
autoOpen:false，
宽度:600，
按钮:{
确定":function(){
$(this).dialog("close");
}，
取消":function(){
$(this).dialog("close");
}
}
});

//对话框链接
$(''#dialog_link'').click(function(){
$(''#dialog'').dialog(''open'');
返回false;
});

//将鼠标悬停在静态小部件上的状态
$(''#dialog_link，ul#icons li'').hover(
函数(){$(this).addClass(''ui-state-hover''); }，
函数(){$(this).removeClass(''ui-state-hover''); }
);

});
</script>

$(function () {
//Dialog
$(''#dialog'').dialog({
autoOpen: false,

buttons: {
"Ok": function () {
$(this).dialog("close");
},
"Cancel": function () {
$(this).dialog("close");
}
}
});

//Dialog Link
$(''#dialog_link'').click(function () {
$(''#dialog'').dialog(''open'');
return false;
});

//hover states on the static widgets
$(''#dialog_link, ul#icons li'').hover(
function () { $(this).addClass(''ui-state-hover''); },
function () { $(this).removeClass(''ui-state-hover''); }
);

});
</script>


holiday.aspx.cs

public string[] RetrieveData(int id)
    {
        CDisplay objdisplay = new CDisplay();
        string[] objdesc = new string[2];
        objdesc=objdisplay.RetrieveDescription(id);
        return objdesc;
    }

display.cs

公共字符串[] RetrieveDescription(int id)

字符串connectionstring =数据源=.\\ SQLEXPRESS; AttachDbFilename = E:\\ HolidayApps \\ App_Data \\ holidaydatabase.mdf;集成安全性= True; Connect Timeout = 30;用户实例= True";
字符串说明= null;

sqlconnection =新的SqlConnection(connectionstring);
sqlcommand = new SqlCommand(从tblHoliday中选择位置，说明，其中hid =" + id，sqlconnection);
sqlconnection.Open();

string [] arr =新字符串[2];
while(sqlreader.Read())
{
arr [0] = sqlreader ["description"].ToString();
arr [1] = sqlreader ["occation"].ToString();

}
return arr;

}
