jquery ui autocomplete

今天用了点jquery ui的autocomplete插件，过程中可谓是遇到了许多问题，坎坎坷坷总算是成功了；具体的实现方法参见"http://jqueryui.com/"。这里面写的很详细，我只说两点注意事项：
1.注意jquery ui的版本，新的1.8+的实现方法和以前不同；
2.我们多数需要自己组装数据源，可以是本地数据源为本地js数组或本地的json对象；
3.形如

var availableTags = [
			"ActionScript",
			"AppleScript",
			"Asp",
			"BASIC",
			"C",
			"C++",
			"Clojure",
			"COBOL",
			"ColdFusion",
			"Erlang",
			"Fortran",
			"Groovy",
			"Haskell",
			"Java",
			"JavaScript",
			"Lisp",
			"Perl",
			"PHP",
			"Python",
			"Ruby",
			"Scala",
			"Scheme"
		];

的数组可以直接用插件会自动在其中搜索；如果是形如

var projects = [
			{
				value: "jquery",
				label: "jQuery",
				desc: "the write less, do more, JavaScript library",
				icon: "jquery_32x32.png"
			},
			{
				value: "jquery-ui",
				label: "jQuery UI",
				desc: "the official user interface library for jQuery",
				icon: "jqueryui_32x32.png"
			},
			{
				value: "sizzlejs",
				label: "Sizzle JS",
				desc: "a pure-JavaScript CSS selector engine",
				icon: "sizzlejs_32x32.png"
			}
		];

一定要label或者value,插件会根据这两个值搜索
