我一直在尋找適合我所有需求的jquery autosuggest插件。需要對jQuery autosuggest插件進行調整
我找到了這一個http://discussion.oslund.ca/2011/01/a-simple-jquery-ajax-autosuggest-plugin/,演示文稿是http://oslund.ca/demos/ausu/。
但是,我需要對其默認行爲進行重大調整。
當前,當用戶通過鍵盤或鼠標選擇一個項目時,插件會使用該值填充搜索框。
取而代之,我希望項目具有實際的鏈接,將用戶帶到該頁面。
但我對javascript/jquery不夠了解,無法做出調整。
請幫助我。

PHP:
<?php
echo "<li><a href='#'>UK</a></li><li><a href='#'>USA</a></li><li><a href='#'>Mexico</a></li>";
?>
的PHP返回列表項,顯然會被連接到一個實際的數據庫時,其在生產中。

嘿嘿,謝謝您的回答,但恐怕沒有奏效。它會像以前一樣執行相同的操作,即填充搜索框。 – jamjam 2012-02-21 16:10:04
