標題[問題] 我把程式碼貼給大家看
時間Thu Aug 26 11:31:30 2010
首先是.cs檔，我解釋一下這個程式是在幹嘛
首先有一個網頁會傳一個值過來
再從資料庫去抓如果資料庫id等於這一個值我要他後面四個欄位存進label在網頁可以
顯示出來
那下面那一個程式碼是類似的，他是另外一個資料庫，一樣要跟傳過來的值比對
比對對了我要他後面四個欄位存進textbox裡(這裡是因為label抓不到，所以我改
存進textbox裡，當時想這樣就可以用document.getElementById("textboxid");
這一個方法，但抓出來的值還是undefined(囧)現在附上我的程式碼:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Update_health : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
GridView1.DataBind();
string j = Request.QueryString["dev_hea_id"];
for (int i = 0; i <= GridView1.Rows.Count-1; i++)
{
if (GridView1.Rows[i].Cells[0].Text == j)
{
Label7.Text = GridView1.Rows[i].Cells[1].Text;
Label8.Text = GridView1.Rows[i].Cells[2].Text;
Label9.Text = GridView1.Rows[i].Cells[3].Text;
Label10.Text = GridView1.Rows[i].Cells[4].Text;
}
else
{
continue;
}
}
TextBox[,] txtAry = new TextBox[,] { {TextBox1, TextBox2, TextBox3, TextBox4},
{TextBox6, TextBox7, TextBox8, TextBox9},
{TextBox11, TextBox12, TextBox13, TextBox14},
{TextBox16, TextBox17, TextBox18, TextBox19},
{TextBox21, TextBox22, TextBox23, TextBox24},};
if (!IsPostBack)
{
for (int i = 0; i <= GridView2.Rows.Count - 1; i++)
{
if (GridView2.Rows[i].Cells[1].Text == j)
{
int w = 0;
txtAry[i, w].Text = GridView2.Rows[i].Cells[2].Text;
txtAry[i, w + 1].Text = GridView2.Rows[i].Cells[3].Text;
txtAry[i, w + 2].Text = GridView2.Rows[i].Cells[4].Text;
txtAry[i, w + 3].Text = GridView2.Rows[i].Cells[5].Text;
}
else
{
continue;
}
}
//Page.DataBind();
}
//Response.Write("<script type='text/javascript' language='javascript'>test();</script>");
}
}
過來我說一下.aspx檔，這邊的上半部是寫甘特圖的function
中間是body,textbox的visible是false
下面那一個javascript是要畫甘特圖的程式碼
就在這邊我抓不到textbox的值(ps:我試過把textbox的值visible設true裡面是有值的)
所以就沒辦法畫，附上.aspx檔
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="server">
<html>
<head>
<title></title>
</head>
<body>
<div style="position:relative" class="Gantt" id="GanttChart"></div>
<script language="javascript" type="text/javascript">
//var load = false;
window.onload=function(){

7F：推 leicheong:好像沒看到有Form tag, 你確定textbox們都有正確的 08/26 22:39
8F：→ leicheong:放到form tag裡嗎? 08/26 22:40
9F：→ andymai:ㄜ...有看過實際輸出的Html碼嗎?TextBox的ID應該跟你想像 08/27 12:28
10F：→ andymai:的不一樣... 08/27 12:29
11F：→ andymai:我好像看錯了~不要理我Orz 08/27 12:34
12F：→ moneylove:我抓到值了，好像要用document.getElementById('<% 08/27 15:44
13F：→ moneylove:textboxid.ClientID>'); 08/27 15:44
14F：→ andymai:嗯~那的確是輸出ID不一樣~用ClientID是對的~應該是因為有 08/27 18:33
15F：→ andymai:包在MasterPage的關係~因為我用普通網頁不會有這問題~糟! 08/27 18:37
16F：→ andymai:太久沒寫Web Form~一整個忘很大... 08/27 18:37
