Ajax Autocomplete for jQuery
|
||||

Instance Methods
|
||||
Autocomplete instance has following methods:
|
||||
|
||||
setOptions(options): you may update any option at any time. Options are listed above.
|
||||
clear: clears suggestion cache and current suggestions.
|
||||
clearCache: clears suggestion cache.
|
||||
disable: deactivate autocomplete.
|
||||
enable: activates autocomplete if it was deactivated before.
|
||||
hide: hides suggestions.
|
||||
dispose: destroys autocomplete instance. All events are detached and suggestion containers removed.
|
||||
There are two ways that you can invoke Autocomplete method. One is calling autocomplete on jQuery object and passing method name as string literal. If method has arguments, arguments are passed as consecutive parameters:
|
||||
|
||||
$('#autocomplete').autocomplete('disable');
|
||||
$('#autocomplete').autocomplete('setOptions', options);
|
||||
Or you can get Autocomplete instance by calling autcomplete on jQuery object without any parameters and then invoke desired method.
|
||||
|
||||
$('#autocomplete').autocomplete().disable();
|
||||
$('#autocomplete').autocomplete().setOptions(options);
|
||||
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);
|
||||
}
|
||||
});
|
||||
Custom lookup function:
|
||||
|
||||
$('#autocomplete').autocomplete({
|
||||
lookup: function (query, done) {
|
||||
// Do Ajax call or lookup locally, when done,
|
||||
// call the callback and pass your results:
|
||||
var result = {
|
||||
suggestions: [
|
||||
{ "value": "United Arab Emirates", "data": "AE" },
|
||||
{ "value": "United Kingdom", "data": "UK" },
|
||||
{ "value": "United States", "data": "US" }
|
||||
]
|
||||
};
|
||||
|
||||
done(result);
|
||||
},
|
||||
onSelect: function (suggestion) {
|
||||
alert('You selected: ' + suggestion.value + ', ' + suggestion.data);
|
||||
}
|
||||
});
|
||||
Styling
|
||||
Generated HTML markup for suggestions is displayed below. You may style it any way you'd like.
|
||||
|
||||
<div class="autocomplete-suggestions">
|
||||
<div class="autocomplete-group"><strong>NHL</strong></div>
|
||||
<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; }
|
||||
.autocomplete-group { padding: 2px 5px; }
|
||||
.autocomplete-group strong { display: block; border-bottom: 1px solid #000; }
|
||||
Response Format
|
||||
Response from the server must be JSON formatted following JavaScript object:
|
||||
|
||||
{
|
||||
// Query is not required as of version 1.2.5
|
||||
"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 {
|
||||
suggestions: $.map(response.myData, function(dataItem) {
|
||||
return { value: dataItem.valueField, data: dataItem.dataField };
|
||||
})
|
||||
};
|
||||
}
|
||||
})
|
||||
Grouping Results
|
||||
Specify groupBy option of you data property if you wish results to be displayed in groups. For example, set groupBy: 'category' if your suggestion data format is:
|
||||
|
||||
[
|
||||
{ value: 'Chicago Blackhawks', data: { category: 'NHL' } },
|
||||
{ value: 'Chicago Bulls', data: { category: 'NBA' } }
|
||||
]
|
||||
Results will be formatted into two groups NHL and NBA.
|
||||
|
||||
Known Issues
|
||||
If you use it with jQuery UI library it also has plugin named autocomplete. In this case you can use plugin alias devbridgeAutocomplete:
|
||||
|
||||
$('.autocomplete').devbridgeAutocomplete({ ... });
|
||||
It seems that for mobile Safari click events are only triggered if the CSS of the object being tapped has the cursor set to pointer:
|
||||
|
||||
.autocomplete-suggestion {
|
||||
cursor: pointer;
|
||||
}
|
||||
