typeerror typeahead.process is not a function

[amarpreetsaini]

typeahead: {
I am using this typehead with bootstrap tagsinput. I am getting " typeerror typeahead.process is not a function " error when i query .
$('#mystuff_tag_box').tagsinput({
typeahead: {
source: function (query, process) {
return $.getJSON(
'{% url "autocomplete_tag" %}',
{ term: query },
function (data) {
return process(data);
});
},
})

If i try only typeahead then it works fine. But does not work with bootstrap tagsinput.

[bassjobsen]

Try typeahead.updater instead of process.

Note i tried some basic example which seems to work as expected, see the following code:

$('.typeahead').tagsinput({typeahead :
{
items: 4,
source: ["Alabama","Alaska","Arizona","Arkansas","California","Colorado","Connecticut","Delaware","Florida","Georgia","Hawaii","Idaho","Illinois","Indiana","Iowa","Kansas","Kentucky","Louisiana","Maine","Maryland","Massachusetts","Michigan","Minnesota","Mississippi","Missouri","Montana","Nebraska","Nevada","New Hampshire","New Jersey","New Mexico","New York","North Dakota","North Carolina","Ohio","Oklahoma","Oregon","Pennsylvania","Rhode Island","South Carolina","South Dakota","Tennessee","Texas","Utah","Vermont","Virginia","Washington","West Virginia","Wisconsin","Wyoming"]
}});

I removed the reponse. Works fine now. I guess i didnot need it in first place. Thanx for your help.

[bassjobsen]

The code shown below uses the typeahead option of bootstrap tagsinput:

$('.typeahead').tagsinput({typeahead :
{
source: ["Alabama","Alaska"]
}});

Bootstrap tagsinput use the source parameter only. When using this typeahead option bootstrap tagsinput initiates a new typeahead class: self.$input.typeahead. Bootstrap tagsinput's typeahead classes overwrite the original source function and has a call to process already as shown below:

    self.$input.typeahead({
      source: function (query, process) {
        function processItems(items) {
          var texts = [];

          for (var i = 0; i < items.length; i++) {
            var text = self.options.itemText(items[i]);
            map[text] = items[i];
            texts.push(text);
          }
          process(texts);
        }

        this.map = {};
        var map = this.map,
            data = typeahead.source(query);

        if ($.isFunction(data.success)) {
          // support for Angular promises
          data.success(processItems);
        } else {
          // support for functions and jquery promises
          $.when(data)
           .then(processItems);
        }
      }

Notice Bootstrap tagsinput's examples also show an example such as: $('input').tagsinput().typehead({}). Bugs for these calls are already reported: mdbootstrap/bootstrap-templates#42 and mdbootstrap/bootstrap-templates#44

I tried all yours link before, but it seem doesn't work.

[bassjobsen]

Can you post the example code you already have?

            $('#idSchool').val(map[item].id);
            $("#school").prop('maxLength', item.length);
            return item;
        }
});

i want to use event like focus,open,close.
then i tried follow this document
https://github.com/twitter/typeahead.js/blob/master/doc/jquery_typeahead.md
http://ericsaupe.com/using-twitter-typeahead-js-custom-event-triggers/

but looklike nothing happen.

[bassjobsen]

Hi @tuarender,

Thanks for posting your code. You also referrer to twitter/typeahead.js. Please notice the repository contains the typeahead plugin which original was built-in in TB2. TB3 drops support for this plugin in favor for twitter/typeahead.js. You can not use the documentation of twitter/typeahead.js for the plugin in this repository.

Also notice the plugin don't have any open / close event. The plugin implements a select and focus function (event). You can set the select function as an option (the focus not), but you have to realize that this removes the original focus event:

$('.typeahead').typeahead(
{
items: 4,
source: ["Alabama","Alaska","Arizona","Arkansas","California","Colorado","Connecticut","Delaware","Florida","Georgia","Hawaii","Idaho","Illinois","Indiana","Iowa","Kansas","Kentucky","Louisiana","Maine","Maryland","Massachusetts","Michigan","Minnesota","Mississippi","Missouri","Montana","Nebraska","Nevada","New Hampshire","New Jersey","New Mexico","New York","North Dakota","North Carolina","Ohio","Oklahoma","Oregon","Pennsylvania","Rhode Island","South Carolina","South Dakota","Tennessee","Texas","Utah","Vermont","Virginia","Washington","West Virginia","Wisconsin","Wyoming"],
select: function(){var val = this.$menu.find('.active').data('value'); console.log(val);}
});

Alternatively you can extend either the select and focus function to keep it's original functionality by using the following code:

/* make a "copy" of the original function */
var tmp = $.fn.typeahead.Constructor.prototype.select;
/* overwrite the select function */
$.fn.typeahead.Constructor.prototype.select = function () {
var val = this.$menu.find('.active').data('value'); console.log(val);
/* call the orginal function */
tmp.call(this);
}
$('.typeahead').typeahead(
{
items: 4,
source: ["Alabama","Alaska","Arizona","Arkansas","California","Colorado","Connecticut","Delaware","Florida","Georgia","Hawaii","Idaho","Illinois","Indiana","Iowa","Kansas","Kentucky","Louisiana","Maine","Maryland","Massachusetts","Michigan","Minnesota","Mississippi","Missouri","Montana","Nebraska","Nevada","New Hampshire","New Jersey","New Mexico","New York","North Dakota","North Carolina","Ohio","Oklahoma","Oregon","Pennsylvania","Rhode Island","South Carolina","South Dakota","Tennessee","Texas","Utah","Vermont","Virginia","Washington","West Virginia","Wisconsin","Wyoming"]
});

[cyberabis]

Hi Bass,
First thanks for this plugin! I am also using this integrated with bootstrap tagsinput. As you had mentioned in this chain, tagsinput only allows to pass the "source" option. But I also need to change the "items" and "sorter" options. Any pointers how I could do this?

Thanks,
Abishek

[bassjobsen]

Sorry, i did not found an other solution. This kind of problems seems related to mdbootstrap/bootstrap-templates#44 in the first place.

You can write a "proxy" for your source which does the sorting and item manipluations. If your source is source.xml, than try proxy.php:

$data = file_gets_contents(source.xml); $data = sort($data); echo json_encode( data );

now call proxy.php as your source.

[cyberabis]

Ok, for now I changed the tagsinput javascript source code - that's an easy but hack way though!

[tuarender]

@bassjobsen thx you :) 👍

[collabration]

Hello,

Can somebody explain how to attach dynamic remote URL with json which will be rendering new results based on inputed query?

Right now I have:

$.get('my_url?query=abcd', function(data){
$("#some_input").typeahead({ source:data });
},'json');

works fine but the query paramter is static right now. How to make it dynamic based on user query?

[nicolastrenti]

Hi everyone,

I'm trying to use Bootstrap 3 Typeahead and Bootstrap tags input together, with an external source of data.
This code works perfect for me:

jQuery('#tag_field').tagsinput({typeahead :
{
source: ["Alabama","Alaska","Arizona","Arkansas","California"]
}
});

But when I try to use a dynamic remote URL, it doesn't work anymore. My JS code is now:

jQuery('#tag_field').tagsinput({typeahead :
{
source: function (query) {
   return jQuery.get('tagsearch.php?query=' + query);
}
}
});

My remote URL is a PHP file with a MySQL query, which returns a json encoded array, with the exact same syntax as the above source, for example the result of tagsearch.php?query=tag is:

["tag1","tag2","tag3"]

But when I use this code, here is the result:

Could anyone please help me ? I can't undestand what is wrong... Thanks !

[nicolastrenti]

Ok, I figure it out. The return of my PHP file wasn't considered as a json. I had to add items = JSON.parse(items); in the processItems function in Bootstrap tagsinput's source function:

function processItems(items) {
var texts = [];
items = JSON.parse(items);
for (var i = 0; i < items.length; i++) {
var text = self.options.itemText(items[i]);
console.log(text);
map[text] = items[i];
texts.push(text);
}
process(texts);
}

I'm far from being an expert at Javascript, so I don't really understand why, but it works perfectly now. Sorry for that...

[jared-christensen]

@nicolastrenti

This tripped me up too, you almost had it.

source: function (query, process) {
    return jQuery.get('tagsearch.php?query=' + query, function(data){
        return process(data);
    });
}

[nicholasblexrud]

@jared-christensen, thanks for sharing your code. I was getting an error though saying that process was undefined. Just included process as an argument, and viola!

source: function (query, process) {
    return jQuery.get('tagsearch.php?query=' + query, function(data){
        return process(data);
    });
}

[jared-christensen]

@nicholasblexrud Thanks, I left that off by mistake. I will also fix my example, just incase someone would try to use it.

I use the script mentioned above but it always returns me the first suggestion from the array when I have more

I want to select by clicking on the trigger event, how can I do?

My working example here (with bootstrap tagsinput+bootstrap typeahead)

If the first letter appears only than you can use that line from example:
JSON.parse(result);

Good luck!

<script>
$( document ).ready(function() {                                                    
    /**
     * Typeahead
     */
    var elt = $("#'.$vinput_id.'"); //tagsinput input
    elt.tagsinput({
        typeahead: {
            afterSelect: function(val) { this.$element.val(""); },
            source: function(query) {
                var result = null;
                $.ajax({
                   url: "URL/TO/JSON/SOURCE&term="+query,
                   type: "get",
                   dataType: "html",
                   async: false,
                   success: function(data) {
                       result = data;
                   } 
                });
                console.log(result);

                return  JSON.parse(result);

           }
        }
    });
});

Hello,
I am using bootstrap3 tags input and typeahead.js and I'm getting some inconsistencies as shown in my following code:

// including scripts ....
/js/plugin/bootstrap-tags/bootstrap-tagsinput.js
/js/plugin/bootstrap-tags/plugin/bootstrap3-typeahead.js
// ....

// ....
$(document).ready(function(){
$('#tagsInput').tagsinput({
typeahead: {
source: ['Amsterdam', 'Washington', 'Sydney', 'Beijing', 'Cairo', 'New York']
}
});
});

Well, it seems to work and when I type something, the suggestions appear, but when I press enter on one of them, the input creates 2 tags: one with my 'unfinished typing' and other with the suggestion chosen.

~ Sorry for my english... ~

[KaraMovich]

Bootstrap-3-Typeahead don't work with bloodhound in case of remote url, I edited the line 136 :
if($.isFunction(this.source)) this.source(this.query, $.proxy(this.process, this));
to
if($.isFunction(this.source)) this.source(this.query, $.proxy(this.process, this), $.proxy(this.process, this));

[suwey]

@paulossm see #145, I edit the code add option.noPut to make typeahead wont copy value when use with tagsinput.

I am having trouble integrating bootstrap 3 typeahead with tags input but
with objects as tags. It works if I use only tagsinput on input field, but
if I integrate it with typeahead then it doesn't work and I don't even get
any errors

These are the modules i am using
require('bootstrap-3-typeahead/bootstrap3-typeahead.min.js');
require('bootstrap-tagsinput/dist/bootstrap-tagsinput.min.js');
require('bootstrap-tagsinput/dist/bootstrap-tagsinput.css');

$('#text').tagsinput({
typeahead: {
source: ['Alabama','Alaska','Arizona','Arkansas','California']
}});

@bassjobsen

first, please accept my congratulation for the awesome book on bootstrap.

i am trying to increase the list items of the bootstrap typeahead.

I made following attempts

1. changed the user javascript like so
   <script type="text/javascript"> $('input.typeahead').typeahead({ source: function (query, process) { return $.get('/myphplink', { query: query }, function (data) { console.log(data); data = $.parseJSON(data); return process(data); }); }, minLength: 3, fitToElement: true, items: 15, updater: function (item) { } });

2. changed the source bootstrap3-typeahead defauts

Typeahead.defaults = { source: [], items: 15, };

But typeahead always returns only 10 items no matter what. Is this a bug or I am doing something wrong. Kindly help.
