I cannot set default value for myselect, when user is at the first time at the site. I want to have first option as selected, but user can change his choice and choose another option if he doesn't want default option. Can I do this when I use v-model?
Here is my HTML code:
<div class="form-group">
<label class="control-label" for="docType">Type of document</label>
<select class="form-control" id='docType' name="docType" v-model="docType"
:disabled="noDocChoose == true">
<option value="paragon">Document1</option>
<option value="complaint">Document2</option>
</select>
</div>
And here is my Vue JS code:
data: () => ({
docType: ''
}),
Are you asking if you can make the select have an empty default value? In that case, you would have to add another option that has a blank value. For example:
<select class="form-control" id='docType' name="docType" v-model="docType">
<option value="">- please select -</option>
<option value="paragon">Document1</option>
<option value="complaint">Document2</option>
</select>
The value of the option that matches the docType model would be selected.
Set your docType in data, to the value you want to be the default.
data(){
return {
docType: "paragon"
}
}
Example.
console.clear()
new Vue({
el: ".form-group",
data(){
return {
docType: "paragon"
}
}
})
<script src="https://unpkg.com/vue#2.4.2"></script>
<div class="form-group">
<label class="control-label" for="docType">Type of document</label>
<select class="form-control" id='docType' name="docType" v-model="docType" :disabled="noDocChoose == true">
<option value="paragon">Document1</option>
<option value="complaint">Document2</option>
</select>
</div>

Hi i needed some help where if i select a drop down and select from ajax option and a hidden input field appear how can i do it ?
<div class="form-row">
<div class="col">
<label for="select-price-mode" class="col-form-label">Price Mode</label>
<select class="select-price-mode custom-select-sm col-10" id="select-price-mode" required>
<option selected disabled value="">Select ....</option>
</select>
</div>
<div class="col" hidden>
<label for="select-payment-frequency" class="col-form-label">Payment Frequency</label>
<select class="select-payment-frequency custom-select-sm col-10" id="select-payment-frequency" required>
<option selected disabled value="">Select ....</option>
</select>
</div>
This is my ajax
// Here the calling Ajax for the drop down menu below
$.ajax({
// The url that you're going to post
/*
This is the url that you're going to put to call the
backend api,
in this case, it's
https://ecoexchange.dscloud.me:8080/api/get (production env)
*/
url:"https://ecoexchange.dscloud.me:8090/api/get",
// The HTTP method that you're planning to use
// i.e. GET, POST, PUT, DELETE
// In this case it's a get method, so we'll use GET
method:"GET",
// In this case, we are going to use headers as
headers:{
// The query you're planning to call
// i.e. <query> can be UserGet(0), RecyclableGet(0), etc.
query:"PriceModeGet()",
// Gets the apikey from the sessionStorage
apikey:sessionStorage.getItem("apikey")
},
success:function(data,textStatus,xhr) {
console.log(data);
for (let option of data) {
$('#select-price-mode').append($('<option>', {
value: option.PriceMode,
text: option.PriceMode
}));
}
},
error:function(xhr,textStatus,err) {
console.log(err);
}
});
and this is my ajax response
[
{
"PriceMode": "Price By Recyclables"
},
{
"PriceMode": "Service Charger"
}
]
Where say if i select Price By Recyclables the hidden drop down list appear how can i do it ?
You can use the onchange event to trigger a check and if the user selected the value you want, then display the selectbox. You'd have to add an id to the div with the hidden prop (divToDisplay).
$("#select-price-mode").change(function() {
if(this.value === "Price By Recyclables") {
$('#divToDisplay').removeAttr('hidden');
}
});
Just invoke a function when an option is selected in first select
const checkPriceMode = () => {
let value = $('.select-price-mode').val();
$('.payment-frequency').fadeOut();
if(value === 'Price By Recyclables') $('.payment-frequency').fadeIn();
};
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-row">
<div class="col">

<select onchange="checkPriceMode()" class="select-price-mode custom-select-sm col-10" id="select-price-mode" required>
<option selected disabled value="">Select.....</option>
<option value="Price By Recyclables">Price By Recyclables</option>
<option value="Service Charger">Service Charger</option>
</select>
</div>
<div class="col payment-frequency" hidden>
<label for="select-payment-frequency" class="col-form-label">Payment Frequency</label>
<select class="select-payment-frequency custom-select-sm col-10" id="select-payment-frequency" required>
<option selected disabled value="">Select ....</option>
</select>
</div>
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 $scope.scripts only but you can set as many as needeed. As you can see options1 is just an array which contains the etype property which I need to filter against.
Finally on your descendant dropdowns you would use the filtered options:
<select ng-model="event.script">
<option value="" selected disabled>Select Script</option>
<option ng-repeat="script in scripts" ng-value="script.value" ng-bind="script.value"></option>
</select>
Using ng-hide="event.etype == null || event.etype=='ipad'" and ng-show="event.etype == 'ipad'" on the row tags solved my issue!
In my AngularJS web application,
Plunker : https://plnkr.co/edit/x9uIx5Inkxxt3fqttkkK?p=preview
One of my drop down (First) is not retaining the selected value.
The html code fragment is below.
I know it is something to do with the mapping ng-model="entityPropertyType.propertyId"
The entityPropertyType is a iterated value from the list.
HTML
<div class="form-group" ng-repeat="entityPropertyType in advancedSearch.entityPropertyTypes" >
<label class="control-label col-md-1">Business Card</label>
<div class="col-md-2">
<select class="form-control" ng-model="entityPropertyType.propertyId"
ng-change="businessCardSelected($index, entityPropertyType.propertyId)" >
<option value="">Please select</option>
<option ng-repeat="property in businessCards" value="{{property.propertyId}}">{{property.propertyLabel}}</option>
</select>
</div>
</div>
You should never use ngRepeat to render select options. Use ngOptions directive:
<select class="form-control"
ng-options="property.propertyId as property.propertyLabel for property in businessCards"
ng-model="entityPropertyType.propertyId"
ng-change="businessCardSelected($index, entityPropertyType.propertyId)">
<option value="">Please select</option>
</select>

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');
});
