菲力貓的程式設計

javascript 沒有支援 java的 replaceAll ，不過可以用RegExp來達成 :
ex1 :  replaceAll 小數點
var s1 = "A.B.C";
alert(s1.replace(/\./g,"_"));  //  "A_B_C"

spoolsv.exe占用cpu 100%的解決方法
解決方案: 
1.如果目前你沒有印表機而且不想用這台電腦列印資料，可以在“我的電腦”右鍵“管理”裡的“服務”項目中找到“Print Spooler（將文件加載到記憶體中以便打 印。）”找到，停止並且禁用就可以了。
 
2.如果仍需要使用印表機 就先停止spoolsv進程, 進入你的系統文件夾! C:\WINDOWS\system32\spool\PRINTERS 
把其中的文件都刪掉! 再運行 net start spooler 你就會發現一切都好了

直接加入style屬性就可以了...
<input type="text"   style="border:none;background-color:white"  >

操作<Select> 物件
$("#test").find('option:selected').text();  //取得選取項的text文字
$("#test").find('option:selected').val();   //取得選取項的value值
操作<input> 物件
$("#test").val();   //取得value值

UPDATE table1 a
SET table1_column = (SELECT table2_column
FROM table2
WHERE ID = a.ID)

Adding column to a table :
    ALTER TABLE table_name
     ADD column_name column-definition;
For example:
    ALTER TABLE supplier
     ADD supplier_name  varchar2(50);
