我想将隐藏输入字段中的值传递给bloodhound中的搜索远程URL参数。
变量是动态的,每次模态弹出窗口打开时都会更新。它的初始值为null,我相信这就是为什么它根本不起作用的原因:
url: url + 'equipment/getSuggestions/' + $('#equipment-type-input').val() + '/%QUERY',
正如您所看到的,我正在使用jQuery,但值为空。可能是因为它只是在插件初始化时才获得一次?
这里是完整的脚本:
// Instantiate the Bloodhound suggestion engine
var suggestions = new Bloodhound({
datumTokenizer: function (datum) {
return Bloodhound.tokenizers.whitespace(datum.value);
},
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url: url + 'equipment/getSuggestions/' + $('#equipment-type-input').val() + '/%QUERY',
wildcard: '%QUERY',
filter: function (movies) {
// Map the remote source JSON array to a JavaScript object array
return $.map(movies, function (movie) {
return {
value: movie
};
});
}
}
});
// Initialize the Bloodhound suggestion engine
suggestions.initialize();
// Instantiate the Typeahead UI
$('#equipment-id-input').typeahead(null, {
displayKey: 'value',
source: suggestions.ttAdapter()
});
答案 0 :(得分:0)
您可以将Bloodhound的远程设置为以下内容:
remote: {
url: '/equipment/getSuggestions/%EQUIPMENT/%QUERY',
replace: function(url) {
return url.replace('%EQUIPMENT', $('#equipment-type-input').val()).replace('%QUERY', $('input.typeahead.tt-input').val());
},
filter: function (movies) {
// Map the remote source JSON array to a JavaScript object array
return $.map(movies, function (movie) {
return {
value: movie
};
});
}
}
您不再需要通配符,因为您必须替换替换参数中的%QUERY。

我最终以这种方式解决了问题:
// Instantiate the Bloodhound suggestion engine
var suggestions = new Bloodhound({
datumTokenizer: function (datum) {
return Bloodhound.tokenizers.whitespace(datum.value);
},
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url: url + 'equipment/getSuggestions/',
replace: function (url, query) {
return url + query.toUpperCase() + '/' + $('#equipment-type-input').val()
},
wildcard: '%QUERY',
filter: function (numbers) {
// Map the remote source JSON array to a JavaScript object array
return $.map(numbers, function (number) {
return {
value: number
};
});
}
}
});
// Initialize the Bloodhound suggestion engine
suggestions.initialize();
// Instantiate the Typeahead UI
$('#equipment-id-input').typeahead({
hint: true,
highlight: true,
minLength: 3
}, {
limit: 7,
displayKey: 'value',
source: suggestions.ttAdapter(),
});
