Typehead.js不发送ajax请求

Question

我想用typeahead.js和json文件。但是，当我键入到键入输入时，不发送ajax请求。

的javascript：

var users = new Bloodhound({ 
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace('name'), 
    queryTokenizer: Bloodhound.tokenizers.whitespace, 
    limit: 10, 
    prefetch: { 
    url: '/users.json', 
    filter: function(list) { 
     return $.map(list, function(user) { return { name: user }; }); 
    } 
    } 
}); 

users.initialize(); 

$('#prefetch .typeahead').typeahead(null, { 
    name: 'users', 
    displayKey: 'name', 
    // `ttAdapter` wraps the suggestion engine in an adapter that 
    // is compatible with the typeahead jQuery plugin 
    source: users.ttAdapter() 
}); 

轨控制器：

def index 
    @users = User.all 
    @search = User.select :name 
    render json: @search 
end

下面是使用权代码： 在你的JavaScript ：

var users = new Bloodhound({ 
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace('name'), 
    queryTokenizer: Bloodhound.tokenizers.whitespace, 
    limit: 10, 
    remote: { 
    url: '/users.json', 
    filter: function(list) { 
     return $.map(list, function(user) { return { name: user }; }); 
    } 
    } 
});
