我有一个下拉列表,有多个选项可供选择。当我选择value1(公司)时,自动完成应该使用服务调用。当我选择value2时,应该使用lookup。
我该如何实现?
$('#qckSearchKeyword').autocomplete({
serviceUrl: function() {
var option = $('#qck-unspsc').val();
if (option == "country") {
// when country selected through drop down i should use lookup rather then service call
serviceloc = "getCountries";
localStorage.option = "country";
}
if (option == "industry") {
serviceloc = "getSicCode";
localStorage.option = "sicCode";
}
return serviceloc;
},
onSelect: function(suggestion) {
localStorage.tmpSelectedTxt = $.trim($('#qckSearchKeyword').val());
$('#selectFromSuggestions').val("true");
$('#qckSearchKeyword').focus();
},
paramName: "searchTerm",
delimiter: ",",
minChars: 3,
transformResult: function(response) {
// alert(response);
return {
suggestions: $.map($.parseJSON(response), function(item) {
return {
value: item.suggesCode,
data: item.suggesString
};
})
};
}
});

data-type
。我只是复制/粘贴了我过去为此功能所做的一些配置:
...
ajaxOptionsFlight: {
url: '/api/autocomplete/airport/',
type: 'get',
dataType: 'xml'
},
ajaxOptionsHotel: {
url: '/api/locations/hotel/',
type: 'get',
dataType: 'xml'
},
ajaxOptionsCitytrip: {
url: 'http://budapest.onlinetravel.ch/destfinder',
dataType: 'jsonp',
data: {
vendors: 'merger',
client: 'conbe',
filter: 'IATA',
format: 'json',
language: 'en'
}
},
ajaxOptionsCar: {
url: '/api/locations/car/',
dataType: 'json'
},
ajaxOptionsSubstitute: {
url: 'http://gd.geobytes.com/AutoCompleteCity',
dataType: 'jsonp'
},
autocompleteOptions: {
autoFocus: true,
minLength: 1
},
....
之后,我确保可以打开数据类型并将其挂钩到自动完成选项的source
参数上:
autocompleteOptions = $.extend({}, autocompleteOptions, {
source: type === 'citytrip' ? function (request, response) {
ajaxOptions = $.extend(true, {}, ajaxOptionsCitytrip, {
data: {
name: $.trim(request.term),
language: cookieLanguage
},
success: function (d) {
response($.map(d.Destinations, function (item) {
return {
label: item.name + ', ' + item.country,
value: item.name,
code: item.olt_id
};
}));
}
});
$.ajax(ajaxOptions);
} : type === 'flight' ? function (request, response) {
ajaxOptions = $.extend({}, ajaxOptionsFlight, {
url: ajaxOptionsFlight.url + $.trim(request.term),
success: function (d) {
response($.map($(d).find('airport'), function (item) {
return {
label: $(item).children("displayname").text(),
value: $(item).children("displayname").text(),
code: $(item).children("code").text()
};
}));
}
});
$.ajax(ajaxOptions);
} : type === 'hotel' ? function (request, response) {
// and so on ...
}
});
我承认,这不是最优雅的写作方式。但它基本上是数据类型和配置选项之间的简单映射,以提供自动完成功能。 最后我只打电话:
input.autocomplete(autocompleteOptions);
我们已经完成了。希望这是有道理的。
