Make multiselect selected elements appear outside textbox - javascript

Right now I am using the jQuery plugin Chosen (https://harvesthq.github.io/chosen/)
The multiselect option is exactly what I want to achieve, but I'd like if the selected elements appeared outside of the textbox instead of inline the others. Any quick solutions? Or should I be looking at a custom coded attempt?

A bit brute but might be effective. Add your own chosen().change() event handler (as per their docs) to the texbox and simply move the <li> elements from the textbox to wherever you like. So something along the lines of:
$("#form_field").chosen().change(
// detach from source and append to destination
);

Better way to get an element from a parent by class in JQuery

Say I want to put a button in an HTML table that gives me the value of the neighbor cell upon clicking it.
I have this sample JQuery code: console.log($(this).parent().parent().children('.name-cell').get(0).innerText);
In which $(this) is a button in a table cell, the rest of the line gets a neighbor cell with a specific class name name-cell and returns its value or text.
This one works but since I'm new to JS I don't know if it's the correct way to do it since it looks very clumsy.
Is there any other way I'm not aware of?
JQuery .siblings() is what you need
$(this).siblings('.name-cell').text();

Rerender Dynamic Elements when using jQuery Plugin Selectize and Bootstrap-Switch

I am new to jQuery so please go easy, I have a form that will represent an Advanced Search. Users will be able to add rows to refine their specific search.
Each row has 3 elements: A Checkbox & 2 x Select boxes.
As can be seen in the fiddle I am using jquery to clone the row and place the cloned row after the last row.
Everything is working fine except visually I would like the checkbox to use Bootstrap-Switch http://www.bootstrap-switch.org/
And the select boxes to use Selectize https://github.com/brianreavis/selectize.js
Now, when I clone the row with these plugins not active, everything works.
I have NO idea how to re-render or re activate them once a new row is inserted.
Is this something that is plugin specific? Or kind of universal to jquery?
I have read HEAPS of answers on here about similar things but I cannot seem to get it right.
Here is the jquery snippet:
$adSearchForm = $('#adSearchForm');
$adSearchForm.on('click', 'button, input, select, option', function (event) {
console.log("Button Clicked", event)
});
$('#addSearchRow').click(function(event){
$('[data-content=adSearch-3]:first').clone().insertAfter('[data-content=adSearch-3]:last');
// $('.searchByField,.searchOperator').selectize({refreshItems: true});
// $('[data-toggle=switch]').bootstrapSwitch({refreshItems: true});
});
Here is the fiddle, hope its ok. http://jsfiddle.net/CkVQr/6/
Thankyou very much for your help.

Plugins change your HTML
There are two major problems you may not be fully aware of with your code:
Whenever you do a .clone() it merely deep clones your DOM element subtree, but not any event handlers bound to cloned elements.
Your .selectize() plugin changes HTML of your form quite considerably, converting input elements to other things. So whenever you clone your already converted select filter row, and subsequently want to run .selectize() on it again, this particular plugin won't find any suitable input elements to convert. Hence it won't work. Everything will just look as it should but won't work.
What can be done?
The main idea is that whenever you clone your search filter row, you have to clone your original HTML and not after it was converted using your plugins.
HTML Templates to the rescue
One of the possibilities is to change you page (and functionality) a bit and put your search filter row in a template and always use that. When you create your first row, you should read the template (and cache it) and add+convert it on your page. When you'd add an additional row, just use the same cached template and add+convert it again.
HTML template
<script id="filterRow" type="text/x-template">
<!-- Your filter rown HTML goes in here -->
</script>
Some Javascript
var cachedTemplate = cachedTemplate || $("#filterRow").html();
...
$('#addSearchRow').click(function(evt) {
var newRow = cachedTemplate.clone(); // clone for reusability
newRow.insertAfter('[data-content=adSearch-3]:last');
newRow.selectize();
...
});

Refresh/Call PrototypeJs Event from jQuery

I have a Magento Website. I have two js files, one written in Prototype an one in jQuery.
I have two select elements, with about 10 options. From jQuery I'm changing the first select's attribute "selected" (an some more). In Prototype I have a class that creates dependencies between two select elements.
If I click on the first select element and choose an option with the mouse, on the second select element will appear only the options that are linked to the option I choosed in the first select element. This is allready done in prototype.
The idea is that I want to do the click/trigger automatically from jQuery. The first select change it's selected option. But the second select element display all the options (and should display only the options linked to the first select element).
On the Prototype file I have some Event Observers, and I guess that these observers are not triggered from jQuery:
var select_el = $('select_' + id);
...
Event.observe(select_el, 'change', this.update.bindAsEventListener(this));
Event.observe(select_el, 'swatches:change', this.update.bindAsEventListener(this));
...
update: function(event) { ...
So I need somehow to trigger these events from jQuery, or to set an autocheck in Prototype.
Please tell me what should I do.
I've read on stackoverflow that events from Prototype can't be triggered from jQuery. There should be a way to do that. I just haven't found it.
I've tried jQuery functions like:
jQuery("option[value='" + checkedId +"']").attr("selected","selected").parent().focus();
jQuery("option[value='" + checkedId +"']").parent().trigger("onchange");
jQuery("option[value='" + checkedId +"']").parent().trigger('change');
Where the "parent()" is the first select element. The first select element changes as I want, but the second select element should automatically change after the first select is changed. And this never happens. It works only if I click with the mouse on the select and choose manually an option. I want to do this from jQuery, without being necessary to manually click on the desired option.
Thanks for reading this, and now just give me a fix for this problem.
Regards.

Adding HTML element after the dataset is brought in

In Typeahead JS I'm trying to add an option that appears at the bottom of the dropdown after the user has started typing. Currently I'm using the 'onOpened' Custom Event to trigger adding some HTML after the 'tt-dropdown-menu' element is initialised.
.on('typeahead:opened', onOpened)
function onOpened($e) {
$('.tt-dropdown-menu').html( "Add Option" );
}
The problem is that the jQuery HTML is added when the dropdown is initialised, as expected, then when the user starts typing the new dataset element with the autocomplete results in is added below that jQuery HTML so the jQuery HTML can never appear at the bottom of the dropdown. You can't append the jQuery HTML to the dataset either as that element doesn't exist when the dropdown is initialised.
Is there an easier way around this? The other Custom Events don't seem to cover this scenario.
If you only have one dataset, you can do as I do: add a footer to the dataset, and add it as a DOM element, not plain HTML string. You can then change it at will (say on any event you wish) and your changes are reflected in the dropdown.
Example:
$('#myinput').typeahead({
// rest of your regular stuff, like 'name', 'remote', etc.
footer: $('#dropdown-footer'),
});
... where dropdown-footer is the ID of a div you have somewhere in your dom. You can then do things like:
$('#dropdown-footer').html('Hello')

Changing value of select box in Zurb's Foundation via JavaScript

I'm having difficulty changing the value of select box in Zurb's foundation. I'm using the custom forms which just hides the actual select box and uses an unordered list as the select box.
My problem is that the usual method of changing the value of select box doesn't work:
$('#selectboxID').val('something')
The code above assumes that the value of each of the options in the select box is the same with the text:
<option value="1">1</option>
I also tried:
$($('.dropdown ul li')[1]).addClass('current')
$($('.dropdown ul li')[0]).removeClass('current') //remove current class from the other one
But it doesn't work either.
There's also alternative use case when you're binding on change event yourself, you might not want to trigger it. Code to just force a refresh on select:
Foundation.libs.forms.refresh_custom_select(#jQueryElement, true)
where #jQueryElement is a original hidden select.
You have to trigger "change" event after changing selected index.
Example:
// Change selected option
$('#selectboxID').val('something');
// Or use selectedIndex: $("#selectboxID")[0].selectedIndex = 0;
// Fire change event
$('#selectboxID').trigger('change');
Hope this helps
There have been some modifications to the way that the change event is handled recently in the Foundation code.
You can still achieve what you want using the trigger() method, but you have to add a 'force refresh' flag:
$('#selectboxID').trigger('change', true);
If you are using Foundation 3:
Updated to the latest Foundation 3 release.
Setting selectedIndex, using JQuery's val() or anything which triggers a change event is working out of the box.
If you are using Foundation 4:
This seems to be a regression. As a - hopefully temporary - workaround you can force to update the custom select by using the refresh_custom_selection method, e.g.:
Foundation.libs.forms.refresh_custom_selection($('select'))
Note: It is refresh_custom_selection, not refresh_custom_select!
It is not necessary to use the latter (or trigger('change', true)) because they both completely rebuild the custom select, i.e. they re-copy your select options which involves lots of DOM manipulation and it can slow things down a lot. (Depending on the size of your select options and your other code)
On the other hand refresh_custom_selection just updates the displayed value which is a much more lightweight operation.
PS: Instead of refresh_custom_selection you could also use
$('a.current', $select.next()).text($('option:selected', $select).text());
But that code makes assumptions on the generated HTML, so it is better to stick to the provide utility methods
