我試圖顯示不同的數據在表中時,用戶從第一頁選擇不同的選項...我試圖給排序功能使用JavaScript ..但是,顯示的數據是相同的即使用戶選擇不同的選項...顯示不同的數據從數據庫使用選擇選項

這是我的代碼爲我的主網​​頁

的test.html

<form action="index2.php" method="post"> 
    <table border="0"> 
    <tr> 
     <th colspan="3">test</th> 
    </tr> 
    <tr> 
     <td>Select Foreign Agent Country</td> 
     <td></td> 
     <td> 
     <select name="country"> 
     <option value="US">United States</option> 
     <option value="NZ">New Zealand</option> 
     <option value="JP">Japan</option> 
     </select> 
     </td> 
     </tr> 
     <td colspan="3"> 
     <input type="submit" name="formSubmit" value-"Submit"> 
     </td> 
    </table> 
    </form> 

,這是我的代碼,以獲取來自數據庫,連接數據到我的javascript

index2.php

顯示-all.js

function SelectAll(btn) {

有代碼時執行沒有錯誤,但結果總是相同

人知道什麼是錯的我的代碼?

它打你的else語句,因爲你所有的國家特定的代碼只有在orderby被設置時才被檢查,所以如果沒有設置,它會做你的其他的,每次都是相同的代碼。

此外,還有太多的代碼來清理,但我會讓你的你可以做什麼來清除該代碼同比增長也許75%

  1. 檢查清單,如果在設定下令自己的if語句
  2. 檢查排序是在其自己的一套if語句
  3. 找出形式中選擇哪個國家
  4. 讓使用所有這些選項例如查詢:

    $ sql =「SELECT column1,column2,etc FROM auip_wipo_sample $ countryWhereStatement $ sort $ orederedby」;

如果你做正確的邏輯,在$國家變量將包含WHERE國家=「美國」,在$排序的變量將會被包含ASC或DESC和秩序的關鍵字將包含關鍵字的ORDER BY列名

這可以做到節省空間,使事情更容易閱讀,甚至更動態。

此外,儘量不要使用反引號,除非絕對必要。它們對於真正舊版本的MySQL(我的意思是舊的)是必要的,如果字段或表名與MySQL關鍵字相同。否則,你不應該需要它們。
