jQuery UI 實例-自動完成(Autocomplete)

根據用戶輸入值進行搜索和過濾,讓用戶快速找到並從預設值列表中選擇。

如需了解更多有關 autocomplete 部件的細節,請查看 API 文檔 自動完成部件(Autocomplete Widget)。

本章節使用到 search.php 下載。

默認功能

當您在輸入域中輸入時,自動完成(Autocomplete)部件提供相應的建議。在本實例中,提供了編程語言的建議選項,您可以輸入 "ja" 嘗試一下,可以得到 Java 或 JavaScript。

數據源是一個簡單的 JavaScript 數組,使用 source 選項提供給部件。

<!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery UI 自動完成(Autocomplete) - 默認功能</title> <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.9.1.js"></script> <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script> <link rel="stylesheet" href="http://jqueryui.com/resources/demos/style.css"> <script> $(function() { var availableTags = [ "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++", "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran", "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl", "PHP", "Python", "Ruby", "Scala", "Scheme" ]; $( "#tags" ).autocomplete({ source: availableTags }); }); </script> </head> <body> <div> <label for="tags">標籤:</label> <input id="tags"> </div> </body> </html>

包含重音

autocomplete 域使用自定義的 source 選項來匹配帶有重音字元的結果項,即使文本域不包含重音字元也會匹配。但是如果您在文本域中鍵入了重音字元,則不會顯示非重音的結果項。

嘗試鍵入 "Jo",會看到 "John" 和 "J?rn",然後 鍵入 "J?",只會看到 "J?rn"。

<!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery UI 自動完成(Autocomplete) - 包含重音</title> <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.9.1.js"></script> <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script> <link rel="stylesheet" href="http://jqueryui.com/resources/demos/style.css"> <script> $(function() { var names = [ "J?rn Zaefferer", "Scott González", "John Resig" ]; var accentMap = { "á": "a", "?": "o" }; var normalize = function( term ) { var ret = ""; for ( var i = 0; i < term.length; i++ ) { ret += accentMap[ term.charAt(i) ] || term.charAt(i); } return ret; }; $( "#developer" ).autocomplete({ source: function( request, response ) { var matcher = new RegExp( $.ui.autocomplete.escapeRegex( request.term ), "i" ); response( $.grep( names, function( value ) { value = value.label || value.value || value; return matcher.test( value ) || matcher.test( normalize( value ) ); }) ); } }); }); </script> </head> <body> <div> <form> <label for="developer">開發人員:</label> <input id="developer"> </form> </div> </body> </html>

組合框(Combobox)

一個由 Autocomplete 和 Button 創建的自定義部件。您可以鍵入一些字元,來獲得基於您的輸入過濾的結果,或者使用按鈕從完整列表中選擇。

該輸入是從一個已有的 select 元素中讀取,傳遞給帶有自定義的 source 選項的 Autocomplete。

這是一個不被支持的不完美的部件。這裡純粹是為了演示 autocomplete 定製功能。如需了解更多有關該部件工作原理的細節,請點擊這裡查看相關的 jQuery 文章。

遠程 JSONP 數據源

當您在文本域中鍵入字元時,Autocomplete 部件給出建議結果。在本實例中,當您在文本域中至少鍵入兩個字元時,將顯示相關城市的名稱。

在本實例中,數據源是 geonames.org webservice。雖然選擇一個元素後文本域中是該城市名稱,但是會顯示更多的信息以便找到正確的條目。數據也可以回調,顯示在下面的結果框中。

遠程數據源

當您在文本域中鍵入字元時,Autocomplete 部件給出建議結果。在本實例中,當您在文本域中至少鍵入兩個字元時,將顯示相關鳥的名稱。

在本實例中,數據源是可返回 JSON 數據的伺服器端腳本,通過一個簡單的 source 選項來指定。另外,minLength 選項設置為 2,避免查詢返回太多的結果,select 事件用於顯示一些反饋。

<!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery UI 自動完成(Autocomplete) - 遠程數據源</title> <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.9.1.js"></script> <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script> <link rel="stylesheet" href="http://jqueryui.com/resources/demos/style.css"> <style> .ui-autocomplete-loading { background: white url("images/ui-anim_basic_16x16.gif") right center no-repeat; } </style> <script> $(function() { function log( message ) { $( "<div>" ).text( message ).prependTo( "#log" ); $( "#log" ).scrollTop( 0 ); } $( "#birds" ).autocomplete({ source: "search.php", minLength: 2, select: function( event, ui ) { log( ui.item ?

jQuery UI 實例-自動完成(Autocomplete)

遠程緩存

當您在文本域中鍵入字元時,Autocomplete 部件給出建議結果。在本實例中,當您在文本域中至少鍵入兩個字元時,將顯示相關鳥的名稱。

為了提高性能,這裡添加了一些本地緩存,其他與遠程數據源實例相似。在這裡,緩存只保存了一個查詢,並可以擴展到緩存多個值,每個條目一個值。

<!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery UI 自動完成(Autocomplete) - 遠程緩存</title> <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.9.1.js"></script> <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script> <link rel="stylesheet" href="http://jqueryui.com/resources/demos/style.css"> <style> .ui-autocomplete-loading { background: white url("images/ui-anim_basic_16x16.gif") right center no-repeat; } </style> <script> $(function() { var cache = {}; $( "#birds" ).autocomplete({ minLength: 2, source: function( request, response ) { var term = request.term; if ( term in cache ) { response( cache[ term ] ); return; } $.getJSON( "search.php", request, function( data, status, xhr ) { cache[ term ] = data; response( data ); }); } }); }); </script> </head> <body> <div> <label for="birds">鳥:</label> <input id="birds"> </div> </body> </html>

可滾動的結果

當顯示一個長列表的選項時,您可以簡單地為 autocomplete 菜單設置 max-height 來防止菜單顯示太長。嘗試鍵入 "a" 或 "s" 來獲得一個可滾動的長列表的結果。

<!doctype html> <html> <head> <meta charset="utf-8"> <title>jQuery UI 自動完成(Autocomplete) - 可滾動的結果</title> <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.9.1.js"></script> <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script> <link rel="stylesheet" href="http://jqueryui.com/resources/demos/style.css"> <style> .ui-autocomplete { max-height: 100px; overflow-y: auto; /* 防止水平滾動條 */ overflow-x: hidden; } /* IE 6 不支持 max-height * 我們使用 height 代替,但是這會強制菜單總是顯示為那個高度 */ * html .ui-autocomplete { height: 100px; } </style> <script> $(function() { var availableTags = [ "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++", "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran", "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl", "PHP", "Python", "Ruby", "Scala", "Scheme" ]; $( "#tags" ).autocomplete({ source: availableTags }); }); </script> </head> <body> <div> <label for="tags">標籤:</label> <input id="tags"> </div> </body> </html>

XML 數據

本實例演示如何獲取一些 XML 數據,並使用 jQuery 的方法解析它,然後把它提供給 autocomplete 作為數據源。

本實例也可作為解析遠程 XML 數據源的參考 - 解析在每次 source 回調請求時發生。

"Selected: " + ui.item.value + ", geonameId: " + ui.item.id : "Nothing selected, input was " + this.value ); } }); } }); }); </script> </head> <body> <div> <label for="birds">London 匹配:</label> <input id="birds"> </div> <div stylex="margin-top:2em; font-family:Arial"> 結果: <div id="log" stylex="height: 200px; width: 300px; overflow: auto;"></div> </div> </body> </html>
