#Ajax AutoComplete for jQuery
Ajax Autocomplete for jQuery allows you to easily create
autocomplete/autosuggest boxes for text input fields.
Has no dependencies other than jQuery.
The standard jquery.autocomplete.js file is around 2.7KB when minified via Closure Compiler and gzipped.
##API
* `$(selector).autocomplete(options);`
* Sets up autocomplete for input field(s).
* `options`: An object literal which defines the settings to use for the autocomplete plugin.
* `serviceUrl`: Server side URL that provides results for suggestions. Optional if local lookup data is provided.
* `lookup`: Lookup array for the suggestions. It may be array of strings or `suggestion` object literals.
* `suggestion`: An object literal with the following format: `{ value: 'string', data: any }`.
* `onSelect`: `function (suggestion) {}` Callback function invoked when user selects suggestion
from the list. `this` inside callback refers to input HtmlElement.
* `minChars`: Minimum number of characters required to trigger autosuggest. Default: `1`.
* `maxHeight`: Maximum height of the suggestions container in pixels. Default: `300`.
* `deferRequestBy`: Number of miliseconds to defer ajax request. Default: `0`.
* `width`: Suggestions container width in pixels, e.g.: 300. Default: `auto`, takes input field width.
* `params`: Additional parameters to pass with the request, optional.
* `formatResult`: `function (suggestion, currentValue) {}` custom function to
format suggestion entry inside suggestions container, optional.
* `delimiter`: String or RegExp, that splits input value and takes last part to as query for suggestions.
Useful when for example you need to fill list of coma separated values.
* `zIndex`: 'z-index' for suggestions container. Default: `9999`.
* `type`: Ajax request type to get suggestions. Default: `GET`.
* `noCache`: Boolean value indicating whether to cache suggestion results. Default `true`.
* `onSearchStart`: `function (query) {}` called before ajax request. `this` is bound to input element.
* `onSearchComplete`: `function (query) {}` called after ajax response is processed. `this` is bound to input element.
* `tabDisabled`: Default `false`. Set to true to leave the cursor in the input field after the user tabs to select a suggestion.
##Usage
Html:
<input type="text" name="country" id="autocomplete"/>
Ajax lookup:
$('#autocomplete').autocomplete({
serviceUrl: '/autocomplete/countries',
onSelect: function (suggestion) {
alert('You selected: ' + suggestion.value + ', ' + suggestion.data);
}
});
Local lookup (no ajax):
var countries = [
{ value: 'Andorra', data: 'AD' },
// ...
{ value: 'Zimbabwe', data: 'ZZ' }
];
$('#autocomplete').autocomplete({
lookup: countries,
onSelect: function (suggestion) {
alert('You selected: ' + suggestion.value + ', ' + suggestion.data);
}
});
##Styling
Generated HTML markup for suggestions is displayed bellow. You may style it any way you'd like.
<div class="autocomplete-suggestions">
<div class="autocomplete-suggestion autocomplete-selected">...</div>
<div class="autocomplete-suggestion">...</div>
<div class="autocomplete-suggestion">...</div>
</div>
Style sample:
.autocomplete-suggestions { border: 1px solid #999; background: #FFF; overflow: auto; }
.autocomplete-suggestion { padding: 2px 5px; white-space: nowrap; overflow: hidden; }
.autocomplete-selected { background: #F0F0F0; }
.autocomplete-suggestions strong { font-weight: normal; color: #3399FF; }
##Response Format
Response from the server must be JSON formatted following JavaScript object:
{
query: "Unit",
suggestions: [
{ value: "United Arab Emirates", data: "AE" },
{ value: "United Kingdom", data: "UK" },
{ value: "United States", data: "US" }
]
}
Data can be any value or object. Data object is passed to formatResults function
and onSelect callback. Alternatively, if there is no data you can
supply just a string array for suggestions:
{
query: "Unit",
suggestions: ["United Arab Emirates", "United Kingdom", "United States"]
}
Important: query value must match original value in the input
field, otherwise suggestions will not be displayed.
