我想使用“startswith”过滤器来过滤结果。现在,下面的代码获取与结果中任何单独单词匹配的所有内容。因此,当用户输入“ex”时,“example”和“一二示例”都会被过滤掉。如何更改此行为以便仅过滤掉“示例”?
var repos;
repos = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
limit: 10,
prefetch: {
name: 'terms',
url: 'search.php',
}
});
repos.initialize();
$('input.typeahead').typeahead(null, {
name: 'repos',
source: repos.ttAdapter(),
templates: {
empty: '<div class="empty-message">No matches.</div>',
suggestion: Handlebars.compile([
'<div class="term-box" id="{{id}}">',
'<p class="term">{{termname}}</p>',
'</div>'
].join(''))
}
});
最佳答案
只需更改子字符串函数,如下所示:
var substringMatcher = function (strs) {
return function findMatches(q, cb) { // an array that will be populated with substring matches
var matches = [];
// regex used to determine if a string contains the substring `q`
//var substrRegex = new RegExp(q, 'i');
// we use starts with instead of substring
var substrRegex = new RegExp('^' + q, 'i');
// iterate through the pool of strings and for any string that
// contains the substring `q`, add it to the `matches` array
$.each(strs, function (i, str) {
if (substrRegex.test(str)) {
matches.push(str);
}
});
cb(matches);
};
};
