基于jQuery实现搜索关键字自动匹配功能(2)

<input /> 初始化 AutoComplete 对象，确保正确加载 DOM 对象，否则IE下的用户可能会出现错误。 $('#query').autocomplete({ serviceUrl: 'service/autocomplete.ashx', // Page for processing autocomplete requests minChars: 2, // Minimum request length for triggering autocomplete delimiter: /(,|;)\s*/, // Delimiter for separating requests (a character or regex) maxHeight: 400, // Maximum height of the suggestion list, in pixels width: 300, // List width zIndex: 9999, // List's z-index deferRequestBy: 0, // Request delay (milliseconds), if you prefer not to send lots of requests while the user is typing. I usually set the delay at 300 ms. params: { country: 'Yes'}, // Additional parameters onSelect: function(data, value){ }, // Callback function, triggered if one of the suggested options is selected, lookup: ['January', 'February', 'March'] // List of suggestions for local autocomplete });

根据文本表单中的输入信息，进行关键字提示匹配。

{ query:'Li', // Original request suggestions:['Liberia','Libyan Arab Jamahiriya','Liechtenstein','Lithuania'], // List of suggestions data:['LR','LY','LI','LT'] // Optional parameter: list of keys for suggestion options; used in callback functions. } jQuery AutoComplete 插件支持 on/off功能，从而控制效果的开关。 var ac = $('#query').autocomplete({ /*parameters*/ }); ac.disable(); ac.enable(); ac.setOptons({ zIndex: 1001 });

3、设置表现样式

最后，用div和css美化表现效果。

<div><div><div><strong>Li</strong>beria</div><div><strong>Li</strong>byan Arab Jamahiriya</div><div><strong>Li</strong>echtenstein</div><div><strong>Li</strong>thuania</div></div></div> .autocomplete-w1 { background:url(img/shadow.png) no-repeat bottom right; position:absolute; top:0px; left:0px; margin:6px 0 0 6px; /* IE6 fix: */ _background:none; _margin:1px 0 0 0; }.autocomplete { border:1px solid #999; background:#FFF; cursor:default; text-align:left; max-height:350px; overflow:auto; margin:-6px 6px 6px -6px; /* IE6 specific: */ _height:350px; _margin:0; _overflow-x:hidden; }.autocomplete .selected { background:#F0F0F0; }.autocomplete div { padding:2px 5px; white-space:nowrap; overflow:hidden; }.autocomplete strong { font-weight:normal; color:#3399FF; } jQuery AutoComplete
