jquery.autocomplete插件简介（续）

对autocomplete的一些参数进行说明

Options:

Name	Type
minChars	Number	Default: 1
执行autocomplete的最小值 The minimum number of characters a user has to type before the autocompleter activates.
delay	Number	Default: 400 for remote, 10 for local
显示自动自动完成选择框的延迟时间 The delay in milliseconds the autocompleter waits after a keystroke to activate itself.
cacheLength	Number	Default: 10
缓存长度 The number of backend query results to store in cache. If set to 1 (the current result), no caching will happen. Must be >= 1.
matchSubset	Boolean	Default: true
匹配子集 Whether or not the autocompleter can use a cache for more specific queries. This means that all matches of "foot" are a subset of all matches for "foo". Usually this is true, and using this options decreases server load and increases performance. Only useful with cacheLength settings bigger than one, like 10.
matchCase	Boolean	Default: false
是否敏感的比较。 Whether or not the comparison is case sensitive. Important only if you use caching.
matchContains	Boolean	Default: false
匹配内容。 Whether or not the comparison looks inside (i.e. does "ba" match "foo bar") the search results. Important only if you use caching. Don't mix with autofill.
mustMatch	Boolean	Default: false
必须完全匹配。 If set to true, the autocompleter will only allow results that are presented by the backend. Note that illegal values result in an empty input box.
selectFirst	Boolean	Default: true
如果设置为true则第一个值会被自动选中。 If this is set to true, the first autocomplete value will be automatically selected on tab/return, even if it has not been handpicked by keyboard or mouse action. If there is a handpicked (highlighted) result, that result will take precedence.
extraParams	Object
额外的参数。 Extra parameters for the backend. If you were to specify { bar:4 }, the autocompleter would call my_autocomplete_backend.php?q=foo&bar=4 (assuming the input box contains "foo"). The param can be a function that is called to calculate the param before each request.
formatItem	Function	Default: Assumes that a single row contains a single value.
格式化结果内容 Provides advanced markup for an item. For each row of results, this function will be called. The returned value will be displayed inside an LI element in the results list. Autocompleter will provide 4 parameters: the results row, the position of the row in the list of results (starting at 1), the number of items in the list of results and the search term.
formatMatch	Function	Default: formatItem is used
格式化匹配项 Use this option if you want to limit the data that autocomplete searches for matches. For example, there may be items you want displayed to the user, but don't want included in the data that's searched. Gets called with the same arguments as formatItem.
formatResult	Function	Default: Assumes either plain data to use as result or uses the same value as provided by formatItem.
格式化结果 Similar to formatItem, but provides the formatting for the value to be put into the input field. Again three arguments: Data, position (starting with one) and total number of data.
multiple	Boolean	Default: false
是否允许多选 Whether to allow more than one autocompleted-value to enter.
multipleSeparator	String	Default: ", "
Seperator to put between values when using multiple option.
width	Number	Default: width of the input Element
选择框的宽度
autoFill	Boolean	Default: false
当选中自动提示框里面的选项时INPUT框内是否自动补全
max	Number	Default: 10
自动完成提示的显示数量
highlight	Boolean , Function	Default: Wraps the search term in a <strong> Element
高亮显示当匹配到选择框的元素。 Whether and how to highlight matches in the select box. Set to false to disable. Set to a function to customize. The function gets the value as the first argument and the search term as the second and must return the formatted value.
scroll	Boolean	Default: true
当结果集大于默认高度时是否使用卷轴显示
scrollHeight	Number	Default: 180
自动完成提示的卷轴高度用像素大小表示
