I have a simple Bootstrap form with a select input:
<div class="form-group">
<label for="category" class="control-label col-sm-3">Category</label>
<div class="input-group col-xs-8">
<select class="form-control" name="category" id="category">
<option value="Fruit">Fruit</option>
<option value="Vegetables">Vegetables</option>
</select>
</div>
</div>
The users now have a requirement to be able to add a new option dynamically to the select menu rather than be restricted to the items on the select menu.
I'm not sure if it's possible to modify a select menu and how to make it consistent with the rest of the Bootstrap framework?
To add an option dynamically, there should be a UI button giving you that choice. To get user input, we can use the window.prompt method.
We then create an option element, set its value attribute and set its name. Then just append these elements and nodes to the DOM with appendChild
Try playing around with this. I added some items like Steak, potatoes and beer.
var addOption = document.getElementById("add-option");
var selectField = document.getElementById("category");
addOption.addEventListener("click", function() {
var item = prompt("What would you like");
var option = document.createElement("option");
option.setAttribute("value", item);
var optionName = document.createTextNode(item);
option.appendChild(optionName);
selectField.appendChild(option);
});

You mean something like this?
some select
<select id="region" class="selectpicker">
<option>region 1</option>
<option>region 2</option>
<option>region 3</option>
</select>
jquery js
$('.selectpicker').selectpicker();
$("#region").on('change', function () {
$(this)
.append('<option>region4</option><option>region5</option>')
.selectpicker('refresh');
});

When clicked, I want to go these links, but it doesn't work.
How can I make it work? Thanks.
<div class="col-lg-2">
<label class="control-label" for="Level">Filter</label>
<select id="EType" class="form-control" name="EType">

You can use this example. This is not MVC framework problem. Probably you used asp.net web form. This framework not working web form. You must use javascript methods. I create an example fastly for you with jQuery.
// find elements
var selectItem = $("#EType")
// handle select and go to link
selectItem.on('change', function(){
location.href = $(this).val();
})

I am trying to add cloning functionality for select boxes.
I have 3 select box: country, state, city and first user select the country and on id basis state select box is populated with options and same with city dropdown will populate only when state is selected.
Then I have add more option where I have regenerate everything. so I am cloning my div but the problem when I change my country instead of showing new state dropdown its returns to previous drop down:
$('.country').on('change',function(){
var id = $(this).val();
callAjax(id);
});
$('.state').on('change',function(){
var id = $(this).val();
callAjax(id);
});
$('#btClone').on('click', function () {
$('#country')
.clone()
.attr('id', 'country_' + i)
.attr('name', 'country_' + i)
.appendTo("#container2");
$('#state')
.clone()
.attr('id', 'state_' + i)
.attr('name', 'state_' + i)
.appendTo("#container2");
i =i+1;
});
My Html looks like
<div id="container1">
<select id="country" name="country" class="hidden country">
</select>
<select id="state" name="state" class="hidden state">
</select>
<select id="city" name="city" class="hidden city">
</select>
<span id="selected-profile"></span>
<div id="addons" class="hidden">
<input type="button" id="btClone" value="Clone the list" style="float:right;" />
</div>
</div>
<div id="container2" style="display:none;"></div>
I want when i click on add new then chose country then change something my ajax call again call but as of now i am unable to do that because i already have options
what exactly do you mean with "instead of showing new state dropdown its returns to previous drop down". I tried your code in a fiddle and it's cloning as expected.
function initRow($row){
$row.find('select[name="country"]').on('change', function () {
var thisRow = $(this).closest('div.row');
var stateDD = thisRow.find($('select[name="state"]'));
stateDD.show();
stateDD.on('change',function(){
var cityDD = thisRow.find('select[name="city"]');
cityDD.show();
cityDD.on('change',function(){
});
});
});
}
$('#container1 .row').each(function(){
initRow($(this));
});
$('#btClone').click(function(){
var rowTemplate = $('#container1 > .row').eq(0).clone();
rowTemplate.find('select[name="state"]').hide();
rowTemplate.find('select[name="city"]').hide();
initRow(rowTemplate.appendTo($('#container1')));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I am building a search result filtering feature. I have a number of select2 dropdown boxes where the user can select multiple values from to either hide or show divs with matching class values. I have a number of divs with classes containing values matching values in the select2 dropdown boxes. How do I go about coding this functionality?
I can only get this to work for one selection, I'd like to be able to select multiple options from the dropdowns.
$('select.filterCandidates').bind('change', function() {
$('select.filterCandidates').attr('disabled', 'disabled');
$('#candidates').find('.row').hide();
var critriaAttribute = '';
$('select.filterCandidates').each(function() {
if ($(this).val() != '0') {
critriaAttribute += '[data-' + $(this).data('attribute') + '*="' + $(this).val() + '"]';
}
});
$('#candidates').find('.row' + critriaAttribute).show();
$('#filterCount').html('Showing ' + $('div#candidates div.row:visible').length + ' Matches');
$('select.filterCandidates').removeAttr('disabled');
});
$('#reset-filters').on("click", function() {
$('#candidates').find('.row').show();
});

just to give you a rough idea as you have not provided any code.
<script>
var SelectedValues = $('#ddlSelect option:selected');
var NotSelectedValues $('#ddlSelect option:not(:selected)');
$(SelectedValues ).each(function () {
$("."+$(this).val()+"").show(); //show all those divs containing
//this class
});
$(NotSelectedValues ).each(function () {
$("."+$(this).val()+"").hide();//hide all those divs containing
//this class
});
</script>
This is a rough idea , The above script will show all of the divs containing the classes you have selected in your select2 with id "ddlSelect" and hide those which you have not selected.
you can put this into a function and call it on onchange event of ddlSelect or whatever and however you want it to.
What I'm trying to achieve here is this: I have a select input that has 3 options : Sale, Rent, Wanted. Depending on which option is selected, there are 3 other select inputs. So lets say I choose Sale then it should show the property sale select input and hide the other two, if I choose Rent then it should show the property rent select input and the hide the other two.
The hiding works well but my issue is when i submit for search using GET, it passes the data of the two other hidden select inputs because they are not disabled. I tried disabling them depending on selection as shown in the below code but it didn't work. Any help?
Here is my code:
<script type="text/javascript">
$('#type').on('change',function(){
if( $(this).val() === "sale"){
$("#propertyrent").hide();
$("#propertywanted").hide();
$("#pricetype").show();
$("#propertysale").show();
document.getElementById("propertyrent").disabled=true;
document.getElementById("propertywanted").disabled=true;
}
else if( $(this).val() === "rent"){
$("#pricetype").hide();
$("#propertyrent").show();
$("#propertywanted").hide();
$("#propertysale").hide();
document.getElementById('propertysale').disabled=true;
document.getElementById('propertywanted').disabled=true;
}
else if( $(this).val() === "wanted"){
$("#pricetype").hide();
$("#propertyrent").hide();
$("#propertywanted").show();
$("#propertysale").hide();
document.getElementById('propertyrent').disabled=true;
document.getElementById('propertysale').disabled=true;
}
});
</script>
<label class="col-sm-3 control-label">Type</label>
<select name="type" id="type">
<option value="sale">Sale</option>
<option value="rent">Rent</option>
<option value="wanted">Wanted</option>
</select>
<div id="propertysale">
<label class="col-sm-3 control-label">Property</label>
<select name="propertysale" id="propertysale" class="form-control col-sm-12">
<option value="all">Any</option>
<option value="houses">Houses</option>
<option value="apartments">Apartments</option>
<option value="land">Land</option>
<option value="buildings">Buildings</option>
<option value="wfsc" >Warehouse / Factory / Store / Chalet</option>
</select>
</div>
<div id="propertyrent" style="display:none;">
<label class="col-sm-3 control-label">Property</label>
<select name="propertyrent" id="propertyrent" class="form-control col-sm-12">
<option value="all">Any</option>
<option value="houses">Houses</option>
<option value="apartments">Apartments / Flats</option>
<option value="wfsc" >Warehouse / Factory / Store / Chalet</option>
</select>
</div>
<div id="propertywanted" style="display:none;">
<label class="col-sm-3 control-label">Property</label>
<select name="propertywanted" id="propertywanted" class="form-control col-sm-12">
<option value="all">Any</option>
<option value="houses">Houses</option>
<option value="apartments">Apartments</option>
<option value="land">Land</option>
<option value="buildings">Buildings</option>
<option value="wfsc" >Warehouse / Factory / Store / Chalet</option>
</select>
Use jQuery selector for any input inside div to disabling them:
$("#yourDiv input, #yourDiv select").prop("disabled", true);
To remove disabled: prop("disabled", false);
here div and your selectbox id is same 'propertyrent','propertywanted','propertysale' change this.
and when you hide or disable selectbox set value blank of select box
The problem is, you are not disabling the select menu. You are disabling the div that contains the select menu
<div id="propertyrent" style="display:none;">..
<select name="propertyrent" id="propertyrent" c...
Use different id for both. It will work
So I need to entirely change a group of drop downs that appear based on the selection of one dropdown. I believe ngChange is the way to go about it, but I am not entirely sure how to change between two sets of divs (or if that is even the best way of doing it.
So I have this dropdown:
<div class="input-group" theme="bootstrap" style="">
<label>Product Type</label>
<select class="dropdown-menu scrollable-menu form-control" style="" ng-model="event.etype" ng-change="setOptions()" id="etype">
<option value="" selected disabled>Select a Product</option>
<option ng-click="type = 'x'">X</option>
<option ng-click="type = 'y'">Y</option>
<option ng-click="type = 'z'">Z</option>
<option ng-click="type = 'q'">Q</option>
<option ng-click="type = 'w'">W</option>
</select>
</div>
If the choice is X, I need one set of drop downs (contained in one row), and if it is anything else, I need an entirely different set (contained in another row).
Here are how the drop downs look:
<div class="col-lg-3">
<label>Numbers</label>
<ui-select-match placeholder="Select Numbers">{{$item.admin_user.name}}</ui-select-match>
<ui-select-choices repeat="a in ams"> {{a.admin_user.name}} </ui-select-choices>
</ui-select>
</div>
</div>
<div class="row col-lg-12" id="nonX">
<div class="col-lg-3">
<div class="input-group" theme="bootstrap">
<label>Super Heroes</label>
<select class="dropdown-menu scrollable-menu form-control" ng-model="superhero" id="script">
<option value="" selected disabled>Select Superhero</option>
<option ng-repeat="superhero in superheroes" ng-value={{superhero}} ng-click="selectHeroe(superhero)">{{superhero.name}}</option>
</select>
</div>
</div>
</div>
</div>
</div>
<div class="row col-lg-12" id="noniPad">
<div class="col-lg-3">
<div class="input-group" theme="bootstrap">
<label>Screen</label>
<select class="dropdown-menu scrollable-menu form-control" ng-model="event.screen" id="screen">
<option value="" selected disabled>Select Screen</option>
<option ng-repeat="screen in screens" ng-value={{screen}} ng-click="selectScreen(screen)">{{screen.name}}</option>
</select>
</div>
</div>
<div class="col-lg-3">
<div class="input-group" theme="bootstrap">
<label>Misc Asset</label>
<select class="dropdown-menu scrollable-menu form-control" ng-model="event.miscasset" id="miscasset">
<option value="" selected disabled>Select Misc Asset</option>
<option ng-repeat="miscasset in miscassets" ng-value={{miscasset}} ng-click="slectMiscAsset(miscasset)">{{miscasset.name}}</option>
</select>
</div>
</div>
</div>
<div class="row m-b-sm m-t-sm"></div>
</div>
The separate drop downs both appear in different rows. So I would need one row to appear if they select iPad and one row to appear if they do not select an iPad.
I would love some help. Thank you!
Your best option would be to set the dropdowns of each one depending on the parent selection. There's no need to create a duplicate div to hold both sets of dropdows.
I removed all css classes and any other markup not relevant to the ng-change to make it clearer.
Your parent dropdown would look like this:
<div>
<label>Product Type</label>
<select ng-model="event.etype" ng-change="setOptions(event.etype)">
<option value="">Select a Product</option>
<option ng-repeat="etype in etypes" ng-value="etype" ng-bind="etype"></option>
</select>
</div>
Take special notice of how the setOptions handler is being passed the ng-model value. This means when an option is selected, it'll automatically set ng-model="event.etype" to the value of that option.
To support this behavior in your controller you need to provide the array of event types:
$scope.etypes = ['gif', 'photo', 'ipad', 'video', 'print'];
Then, on your setOptions method you'll get the selected option and filter your descendant dropdowns
var options1 = [{
etype: 'ipad',
value: '1'
}, {
etype: 'gif',
value: '2'
}];
$scope.setOptions = function (etype) {
$scope.scripts = options1.filter(function (item) {
return item.etype == etype;
});
};
What this means is that setOptions will set the descendant dropdowns based on the etype value passed in. In this example I'm limiting to $scope.scripts only but you can set as many as needeed. As you can see options1 is just an array which contains the etype property which I need to filter against.
Finally on your descendant dropdowns you would use the filtered options:
<select ng-model="event.script">
<option value="" selected disabled>Select Script</option>
<option ng-repeat="script in scripts" ng-value="script.value" ng-bind="script.value"></option>
</select>
Using ng-hide="event.etype == null || event.etype=='ipad'" and ng-show="event.etype == 'ipad'" on the row tags solved my issue!
