通过QueryString(AJAX)传递值时出现问题 [英] Problem in Passing value through QueryString (AJAX)

问题描述

我有一个三列的网格视图.其中有两个文本框和一个下拉列表.
当我从下拉列表中选择一个值时，我需要在两个文本框中填充从数据库中获取值(不回发).

我用rowdatabound来初始化它....

I have an grid view with three columns. In which two textboxes and one dropdownlist.
While i select an value from dropdown i need to fill the two textboxes with fetching values from Database(WITHOUT POSTBACK).

i used rowdatabound to initialize it....

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            TextBox txtpid = e.Row.FindControl("txt_pid") as TextBox;
            DropDownList txtpname = e.Row.FindControl("txt_pname") as DropDownList; //product name is dropdown
            TextBox txtpsize = e.Row.FindControl("txt_psize") as TextBox;
            txtpname.Attributes.Add("onChange", "javascript: return getEmpName(''" + txtpid.ClientID + "'',''" + txtpname.ClientID + "'',''" + txtpsize.ClientID + "'')");
        }
    }

我的通过Querystring从数据库中获取数据的脚本

My script to fetch data from DB through an Querystring

<script type="text/javascript" language="javascript">

function getEmpName(id,name,size) {

$.ajax({

type : "POST",


url : "Getempname.aspx?prod_name=" + $("#name").attr("value"),//Here am getting value of "name" is Undefined

success : function(reponseText) {
var s = reponseText.toString();
var temp = new Array();
temp = s.split(" ");
document.getElementById(id).value = temp[0];
document.getElementById(size).value = temp[1];
}

});

}

</script>

推荐答案

.ajax({ 类型:"POST"， url:"Getempname.aspx?prod_name =" +

.ajax({ type : "POST", url : "Getempname.aspx?prod_name=" +

(#name").attr("value")，//这里获取的是"name"的值是未定义 成功:function(reponseText){ var s = reponseText.toString(); var temp = new Array(); temp = s.split("); document.getElementById(id).value = temp [0]; document.getElementById(size).value = temp [1]; } }); } < /script >

("#name").attr("value"),//Here am getting value of "name" is Undefined success : function(reponseText) { var s = reponseText.toString(); var temp = new Array(); temp = s.split(" "); document.getElementById(id).value = temp[0]; document.getElementById(size).value = temp[1]; } }); } </script>

好，如果您的问题失去了选择，您的代码是否每次都绑定该下拉列表?那将重置选择.对于其余部分，如果您查看源代码，那么使用的ID是控件的正确ID吗?

OK, if your issue is losing your selection, does your code bind that drop down every time ? That would reset the selection. For the rest, if you view the source, is the ID being used the correct ID of the control ?
