jQuery UI 實(shí)例 - 自動(dòng)完成（Autocomplete）
jQuery UI的自動(dòng)完成（Autocomplete）是根據(jù)用戶輸入值進(jìn)行搜索和過濾，讓用戶快速找到并從預(yù)設(shè)值列表中選擇。
如需了解更多有關(guān)autocomplete部件的細(xì)節(jié)，請查看API文檔自動(dòng)完成部件（Autocomplete Widget）。
默認(rèn)功能
當(dāng)您在輸入域中輸入時(shí)，自動(dòng)完成（Autocomplete）部件提供相應(yīng)的建議。在本實(shí)例中，提供了編程語言的建議選項(xiàng)，您可以輸入"ja"嘗試一下，可以得到Java或 JavaScript。
數(shù)據(jù)源是一個(gè)簡單的JavaScript數(shù)組，使用source選項(xiàng)提供給部件。

</html>包含重音
autocomplete域使用自定義的source選項(xiàng)來匹配帶有重音字符的結(jié)果項(xiàng)，即使文本域不包含重音字符也會(huì)匹配。但是如果您在文本域中鍵入了重音字符，則不會(huì)顯示非重音的結(jié)果項(xiàng)。
嘗試鍵入"Jo"，會(huì)看到"John"和"J?rn"，然后鍵入"J?"，只會(huì)看到"J?rn"。

一個(gè)由Autocomplete和Button創(chuàng)建的自定義部件。您可以鍵入一些字符，來獲得基于您的輸入過濾的結(jié)果，或者使用按鈕從完整列表中選擇。
該輸入是從一個(gè)已有的select元素中讀取，傳遞給帶有自定義的source選項(xiàng)的Autocomplete。
這是一個(gè)不被支持的不完美的部件。這里純粹是為了演示autocomplete定制功能。如需了解更多有關(guān)該部件工作原理的細(xì)節(jié)，請點(diǎn)擊這里查看相關(guān)的jQuery文章。

自定義數(shù)據(jù)并顯示
您可以使用自定義數(shù)據(jù)格式，并通過簡單地重載默認(rèn)的聚焦和選擇行為來顯示數(shù)據(jù)。
嘗試鍵入"j"，或者按向下箭頭按鍵，即可得到一個(gè)項(xiàng)目列表。

當(dāng)您在文本域中鍵入字符時(shí)，Autocomplete部件給出建議結(jié)果。在本實(shí)例中，當(dāng)您在文本域中至少鍵入兩個(gè)字符時(shí)，將顯示相關(guān)城市的名稱。
在本實(shí)例中，數(shù)據(jù)源是geonames.org webservice。雖然選擇一個(gè)元素后文本域中是該城市名稱，但是會(huì)顯示更多的信息以便找到正確的條目。數(shù)據(jù)也可以回調(diào)，顯示在下面的結(jié)果框中。
