对autocomplete的一些参数进行说明
Options:
NameTypeminCharsNumber Default: 1执行autocomplete的最小值
The minimum number of characters a user has to type before the autocompleter activates.
delayNumber 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.
cacheLengthNumber 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.
matchSubsetBoolean 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.
matchCaseBoolean Default: false是否敏感的比较。
Whether or not the comparison is case sensitive. Important only if you use caching.
matchContainsBoolean 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.
mustMatchBoolean 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.
selectFirstBoolean 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.
extraParamsObject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.
formatItemFunction 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.
formatMatchFunction 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.
formatResultFunction 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.
