I have a select element with ng-options to populate options and <option value="">Select</option> as a static default option. I want to show another item in options list - Other, if selected, renders a textbox for user to enter other value. I tried adding another static option with value="-1" but it didn't work.
I would try following:
<div ng-init="arr = [{name:'A', val:1},{name:'B', val:2},{name:'C', val:2}]">
<select ng-model="v">
<option ng-repeat="o in arr" value="o.val">{{ o.name }}</option>
<option>Other</option>
</select>
<input type="number" ng-model="otherval" ng-show="v == 'other'"/>
</div>
or,
<div ng-init="arr = [{name:'A', val:1},{name:'B', val:2},{name:'C', val:2}]">
<select ng-model="v" ng-options="o.val as o.name for o in arr.concat([{name:'Other',val:'other'}])">
</select>
<input type="number" ng-model="otherval" ng-show="v == 'other'"/>
</div>

Using AngularJS, there is a requirement to show a dropdown with a selected value:
- When user selects a different value we should show a warning message and shouldn't proceed with update (save button disable).
- When user reverts to the original value, the message should hide and able to update (save button enable)
<select ng-model="vm.sldetails.AgencyGroupID" onchange=""
ng-options="a.AgencyGroupID as a.AgencyGroupName for a in vm.agencygroups">
<option value="">--Select--</option>
</select>
<label ng-show="">Warning message</label>
Instead of calling an event in controller, can we achieve directly in Onchange event?
<div class="col-md-2">
<select class="form-control" ng-model="vm.sldetails.AgencyGroupID"
ng-options="a.AgencyGroupID as a.AgencyGroupName for a in vm.agencygroups">
<option value="">--Select--</option>
</select>
</div>
HTML:
<label class="col-md-2 control-label text-align-left" id="lblWarningMessage" ng-if="vm.sldetails.AgencyGroupID==='your value'">Warning message</label>
In label tag,your value should be replaced by ur compare value
I guess you could try something like this:
<select ng-model="vm.sldetails.AgencyGroupID" ng-change="vm.selectChanged()"
ng-options="a.AgencyGroupID as a.AgencyGroupName for a in vm.agencygroups">
<option value="">--Select--</option>
</select>
<label ng-show="vm.showWarning">Warning message</label>
And in js:
vm.selectChanged = function(){
if(vm.sldetails.AgencyGroupID !== 'the initial value'){
vm.showWarning = true;
}else{
vm.showWarning = false;
}
}
So here is the deal, im getting different objects from ajax request ($scope.productos - $scope.ofertas) and then using ng-foreach for both to show them so user can select multiple items (stored in $pedidoForm.productos and
pedidoForm.ofertas) and this selected items dinamically show up below with another ng-repeat showing the 'nombre' property and adding another new property and value with input but the atribute VALUE is automatically converting any object into a string, resulting in a "{property: value}" so i cant read the property correctly
<div class="row">
<span>Productos</span>
<select class="selectpicker" ng-model="pedidoForm.productos" ng-change=parse(pedidoForm.productos) multiple>
<option ng-repeat="producto in productos" value="{{producto}}"> {{producto.nombre}}
</option>
</select>
</div>
<div class="row">
<span>Ofertas</span>
<select class="selectpicker" ng-model="pedidoForm.ofertas" ng-change="test(pedidoForm)" multiple>
<option ng-repeat="oferta in ofertas" value="{{oferta}}"> {{oferta.nombre}} </option>
</select>
</div>
as I understand you need to select an object, but HTML5 select tag supports only string values. So, try to use ng-options directive:
<div class="row">
<span>Productos</span>
<select class="selectpicker"
multiple
ng-model="pedidoForm.productos"
ng-change="parse(pedidoForm.productos)"
ng-options="producto as producto.nombre for producto in productos track by producto.nombre">
</select>
</div>
<div class="row">
<span>Ofertas</span>
<select class="selectpicker"
multiple
ng-model="pedidoForm.ofertas"
ng-change="test(pedidoForm)"
ng-options="oferta as oferta.nombre for oferta in ofertas track by oferta.nombre">
</select>
</div>

Instead of using the following:
<select class="form-control" disabled>
<option ng-repeat="category in Categories" value="category.id" ng-selected="APIdata.category_id === category.id">{{ category.name }}
</option>
</select>
is it possible to use an input text only since the above selected list is disabled and there is no possibility of changing its value? Categories and APIdata are properties(Categories is an array and APIdata is an object) of $scope. How should we do that?
Add in your controller in the right place:
$scope.category = $scope.Categories.filter(c => c.id === $scope.APIdata.category_id)[0];
Change your view:
<input type="text" ng-model="category" disabled/>
I'm trying to use ng-model to show a series of dropdowns. If I set the top select to empty option then the rest of the dropdowns should be set to the empty option.
<select ng-model="ddl">
<option></option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
<div ng-show="ddl">
<div ng-show="ddl != null">
<select ng-model="ddl1">
<option></option>
<option>4</option>
<option>5</option>
<option>6</option>
</select>
<div ng-show="ddl1">
<select>
<option></option>
<option>7</option>
<option>8</option>
<option>9</option>
</select>
</div>
</div>

You could use the ng-change directive to run a funciton in your controller that set's the dropdowns to empty if the top one is empty.
https://docs.angularjs.org/api/ng/directive/ngChange#!
something like
$scope.reset = function() {
if($scope.ddl === "") {
$scope.ddl1 = ""; $scope.ddl2 = "";
}
}
