因為ASP.NET在Server上有些時候會轉成其他名稱,所以要這樣抓名稱,由Server來轉出HTML上的名稱
document.getElementById("<%=this.控制項ID.ClientID %>").value
母版 Master
document.getElementById('<%= Page.Master.FindControl("ContentPlaceHolder1").FindControl("Button1").ClientID %>').click();
母版這樣也抓的到哦
var id = $get("<%=lbl_case_oid.ClientID%>").innerText;
alert(id);
<script type="text/javascript">
function lookClientID() {
// str = document.getElementById("<%=this.DropDownList2.ClientID%>").value;
//alert(str); //出來是值
str = document.getElementById("<%=this.DropDownList2.ClientID%>");
alert(str.id); //出來是控制項ID
}
</script>
測試文字功能,小工具,標題
記錄很重要,不然會浪費很多時間在找以前的記憶
一個人的氣度,決定他未來的高度。

WScript 的 GetObject Method 用來抓運行中的Process
問題原由: 想抓正在運行中的 Process
過程:上了MSDN查了資料,用MSDN上面 WScript GetObject Method 的VBS範例去改的程式是可以抓到Process的值,但想改用Javascript的寫法一直沒能成功.....
有在網路上找來找去,原以為是GetObject Method沒支援Javascript,後來查到Javascript也有GetObject Method,也先寫成web測試是可以使用,有點撞牆的感覺,中午休息一下後,換個關鍵字再問一下Google老師,結果有了重大的發現 !!!

Excel 2份Excel 相同會員名單 比對 使用 COUNTIF
問題原由 : 某日服務專員反應,因為想知道 VIP客群 是否有來店消費,服務專員想主動關心VIP客人是否有要協助的地方。
其他說明:目前該公司的資訊系統因為某些因素,目前資訊系統尚末有建置相關功能,但該服務專員手頭上有一份 " VIP名單 " 的Excel檔案,資訊系統也能轉每天 " 來店會員 " 的Excel檔案。

msdn範例上的 * 號,應該是用來表示某一資料夾,不然就是誤值
如果有 * 號,在網頁上跑起來會出現錯誤
最好再網路找找其他善心人士的範例比對看看問題出在那邊
