#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 }`.
|
|
* `lookupFilter`: `function (suggestion, query, queryLowerCase) {}` filter function for local lookups. By default it does partial string match (case insensitive).
|
|
* `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.
|
|
* `paramName`: Default `query`. The name of the request parameter that contains the query.
|
|
* `transformResult`: `function(response) {}` called after the result of the query is ready. Converts the result into response.suggestions format.
|
|
* `autoSelectFirst`: if set to `true`, first item will be selected when showing suggestions. Default value `false`.
|
|
* `appendTo`: container where suggestions will be appended. Default value `body`. Can be jQuery object, selector or html element. Make sure to set `position: absolute` or `position: relative` for that element.

##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"]
|
|
}
|
|
|
|
## Non standard query/results
|
|
|
|
If your ajax service expects the query in a different format, and returns data in a different format than the standard response,
|
|
you can supply the "paramName" and "transformResult" options:
|
|
|
|
$('#autocomplete').autocomplete({
|
|
paramName: 'searchString',
|
|
transformResult: function(response) {
|
|
return $.map(response.myData, function(dataItem) {
|
|
return {value: dataItem.valueField, data: dataItem.dataField};
|
|
});
|
|
}
|
|
})
|
|
|
|
|
|
Important: query value must match original value in the input
|
|
field, otherwise suggestions will not be displayed.
