Bootstrap 3 typeahead.js - remote url attributes

Question

I\'m trying to call my remote url with added attributes to the url.

For now I have this working:

$(\'#league\').typeahead({
        remote: \'/typeah         


        

Answer 1

remote is exclusively for typeahead.js (not part of Bootstrap). But you are not using the remote correctly, it can be either a string or an object, not a function.

When you need to change the request URL, you can use replace:

$('#league').typeahead({
    remote: {
        url: '/typeahead/get_league?query=%QUERY',
        replace: function () {
            var q = '/typeahead/get_league?query=%QUERY';
            if ($('#sport').val()) {
                q += "&sport=" + encodeURIComponent($('#sport').val());
            }
            return base_url + q;
        }
    },
    limit: 10
 });

Hope it helps.

Answer 2

Hieu Nguyen solution will not work for %QUERY wildcards. According to Bloodhound.js documentation,

replace – .... If set, no wildcard substitution will be performed on url.

Bloodhound docs on github

So %QUERY will be passed as string without being replaced by text entered from user.

So you should put typeahead value into your url :

$('#league').typeahead({
remote: {
    url: '/typeahead/get_league?query=%QUERY',
    replace: function () {
        var q = '/typeahead/get_league?query=' + $('#league').val();
        if ($('#sport').val()) {
            q += "&sport=" + encodeURIComponent($('#sport').val());
        }
        return base_url + q;
    }
},
limit: 10

});

Here is a complete example with the QUERY result as well passed. Note that when the remote method is used variable substitution no longer functions. Thanks to hieu-nguyen for the majority of it!

jQuery('#city').typeahead({
    name: "cities",
    remote: {
        url: current_web_root + '?action=ajax|getcities&query=%QUERY',
        replace: function () {
            var q = current_web_root + '?action=ajax|getcities&query=' + jQuery('#city').val();
            if (jQuery('#state').val()) {
                q += "&state=" + encodeURIComponent(jQuery('#state').val());
            }
            return q;
        }
    },      
    cache: false
}); 

jQuery("#state").change(function (e) {
    jQuery('#city').val("");
});
