Toggling ng-selected

I am trying to toggle ng-selected options in Angular, but am running into some difficulty. Here's what I'm trying:
<select ng-model="datacut.ages" multiple>
<option value="" disabled="disabled">Please Select</option>
<option value="0-15" ng-click="toggleSelect(datacut, '0-15')" ng-selected="datacut.ages.indexOf('0-15') !== -1">15 and Younger</option>
<option value="16-19" ng-selected="datacut.ages.indexOf('16-19') !== -1">16 - 19</option>
<option value="20-24" ng-selected="datacut.ages.indexOf('20-24') !== -1">20 - 24</option>
</select>
Controller:
$scope.toggleSelect = function(dc, str){
dc.ages.splice(dc.ages.indexOf(str), 1);
//e.currentTarget.selected = !e.currentTarget.selected;
};
The problem is that when I click on an option gets selected on mousedown, and on release gets unselected. The commented out code also does the same thing.
I feel like this should have a simple solution, but I can't really figure out an elegant solution.
Any help would be much appreciated.
Edit: For clarification - I need to be able to have nothing selected, so clicking a single selected element needs to unselect it. I also need to be able to select multiple options.

Your are using ng-model which does the magic for you. So ng-click and ng-selected is not necessary. See my working fiddle
<select ng-model="datacut.ages" multiple>
<option value="" disabled="disabled">Please Select</option>
<option ng-value="'0-15'">15 and Younger</option>
<option ng-value="'16-19'" >16 - 19</option>
<option ng-value="'20-24'" >20 - 24</option>
</select>

It looks like you want to remove the selected age from the ages model. Then you need to use the ng-change directive. And remove the ng-click or ng-selected. But leave the ng-model to access the value on the method that remove the selected item.
See my plunker
<select multiple name="ages" unseletable forbiden-opt="datacut.MIN_AGE" ng-model="datacut.chosenAge">
<option value="" disabled="disabled">Please Select</option>
<option ng-repeat="age in datacut.ages" value="{{age}}">
{{age}}
</option>
</select>
EDIT: This should be made in a directive because you need to update the option html to unselect the option.

Prevent Blank Select in Angular

I updating a form to angular. The selects in it are not generated by angular. I am using angular to add some interactivity and submit the form. I am having an issue where angular is adding a blank select to the element. Is there a way of preventing this without having angular generate the select?
<select name="inventory_status" ng-model="formData.inventory_status">
<option ng-selected="true" ng-value="1">Active</option>
<option ng-value="2">Discontinued</option>
<option ng-value="3">Special Order</option>
<option ng-value="4">Pre-Order</option>
</select>
The above code produces this:
<select name="inventory_status" ng-model="formData.inventory_status" ng-init="sortorder='1'" class="ng-pristine ng-valid ng-touched"><option value="? undefined:undefined ?"></option>
<option ng-selected="true" ng-value="1" value="1" selected="selected">Active</option>
<option ng-value="2" value="2">Discontinued</option>
<option ng-value="3" value="3">Special Order</option>
<option ng-value="4" value="4">Pre-Order</option>
</select>
My hope is to not have this produced:
<option value="? undefined:undefined ?"></option>
Additionally I would like to not have to use angular to generate the dropdown although if that is the only option I could. This only happens when I set this field to ng-model. I am setting it to ng-model because I want to use angular to submit the form.
Thanks in advance.

Set $scope.formData.inventory_status = 1 or whatever value you want selected and it will not show the empty option, plus you don't need ng-selected if you set the value.

Javascript - Plugin should not affect all select boxes

I use a JQuery/Javascript plugin which changes select boxes with:
$('select').multipleSelect();
The select boxes look like:
<select multiple=\"multiple\">\r\n" +
<option selected=\"selected\" value=\"1\">January</option>
<option value=\"2\">December</option>
<option value=\"3\">December2</option>
</select>
The probem is that it changes all select boxes on the site but it should change one select box only.
How to do it?

Just give the select you want to select, a class, and then call the plugin on it
<select class="selectMe" multiple="multiple">
<option selected="selected" value="1">January</option>
<option value="2">December</option>
<option value="3">December2</option>
</select>
And then in jQuery
$('select.selectMe').multipleSelect();
You need not define an actual class in CSS, though you can, if you want. From now on, just add class selectMe to the <select> that you want the plugin to be called upon.

Select a select option element without a "selected" attribute

So here is the thing:
I have a java app and it creates a group of selects based on a db. Also, if it happens that an element (let's call it product) has that value, it print the option with the selected attribute.
<select>
<option value="1">text1</option>
<option value="2" selected>text2</option>
<option value="3">text3</option>
<option value="4">text4</option>
<option value="5">text5</option>
</select>
<select>
<option value="1">text1</option>
<option value="2">text2</option>
<option value="3">text3</option>
</select>
<select>
<option value="1">text1</option>
<option value="2">text2</option>
</select>
What i want to do is set in blank (set a value of zero) to the selects that not has an element with a selected value.
If you know another form to set to blank a list (diferent from put a default empty element in every select), please let me know.

The way to do this without an empty option, is to set the selectedIndex to -1
$('select:not(:has(option[selected]))').prop("selectedIndex", -1);
FIDDLE

Demo $('option:not(:selected)').val(0); use :not and :selected and set the value to 0

How initialize dropdown (<select/>) with preselected value and then change it?

I've got a grid with dropdown in every row and I need to render it's state from DB.
So I've got dropdowns defined like that with selected option specified for preselecting the value from DB.
<select id='selectId'>
<option value='1'>Option 1</option>
<option value='2' selected='selected'>Option 2</option>
<option value='3'>Option 3</option>
</select>​
The problem is in that when I change the value of a dropdown defined like that in a browser it changes on UI but selected attribute don't move and stays where it was.
So when I then call $("#selectId").val() I get the old one value.
What's the appropriate way to initialize dropdown control and then have an ability to freely change it's value in browser or by jQuery?

This seems to be working fine (Firefox on Ubuntu):
HTML
<select id='selectId'>
<option value='1'>Option 1</option>
<option value='2' selected='selected'>Option 2</option>
<option value='3'>Option 3</option>
</select>
JS
$('#selectId').change(function() {
var opt = $(this).find('option:selected');
console.log([opt.val(), opt.text()]);
});
var opt_sel = $('#selectId option:selected');
opt_sel.val(99);
opt_sel.text('Changed option');
If you select the options, you'll see that it will print the changed version. Working example:

Hope this helps.

It should work fine. May be you are not setting it correctly.
You should pass the value of the option to val() method to select it.
E.g $('#selectId').val('1'); will set first option as selected and afterwards calling $('#selectId').val() will give you 1 and not 2.
Here is the working example http://jsfiddle.net/3eu85/

You can get the val of the option selected, instead of the select
$('select#selectId option:selected').val();
Docs: http://api.jquery.com/val/

Which browser are you trying this in? Your code looks fine to me, and appears to be working in this jsFiddle.

please use this code instead,
$('#selectId option:selected').val();
