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;
}
}

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 === $scope.APIdata.category_id)[0];
Change your view:
<input type="text" ng-model="category" disabled/>
I have one drop down and a check box, i want to reset check box value to false whenever drop-down value change. I had already written code for reset check box value to false, but it is not working, please tell me where i am doing wrong.
View:
<label class="item item-input item-select">
<div class="input-label">Leave Type</div>
<select ng-model="LeaveRequest.leaveType" ng-change="leavetypechange(LeaveTypes)" required>
<option value="">Select Leave Type</option>
<option ng-repeat="lt in LeaveTypes"value="{{lt.Name}} ">{{lt.Name}}</option>
</select>
</label>
<div ng-show="ShowPeriod">
<ion-checkbox ng-model="isChecked" >Half day/ Quarter leave</ion-checkbox>
</div>
controller:
.controller('ApplyLeaveCtrl',function($scope, $state, $templateCache,$ionicPopup) {
$scope.leavetypechange=function(){
$scope.isChecked=false;
};
});
$scope.isChecked in loop is creating seperate scope for each item in dropdown.
so you need to put it in service.
.service('dataService', function() {
this.isChecked;
})
here is you working codepen:

Use $parent with isChecked as follow:
<ion-checkbox ng-model="$parent.isChecked" >Half day/ Quarter leave</ion-checkbox>
Using AngularJS I have a list of selected option and one additional "New" option. What I am trying to do is, when "New" option is chosen it will show a text-box to add a new value.
<select ng-model="group.name" ng-options="bl.Name for bl in Groups" >
<option value="VALUE FROM TEXT BOX">New</option>
</select>
<div class="col-md-4" ng-show="WHEN NEW OPTION IS Chosen ">
<input class="text-box" type="text" name="NewValue" ng-model="group.name" />
</div>
You can try like this
Working Demo
<div ng-app='myApp' ng-controller="ArrayController">
<select ng-model="group.name" ng-options="Group.Name for Group in Groups"></select>
<div class="col-md-4" ng-show="group.name.Value == 'new'">
<input class="text-box" type="text" name="NewValue" ng-model="newValue" />
<button ng-click="add(newValue)">Add</button>
</div>
</div>
Just watch for the selected item change:
$scope.displayDiv = false;
$scope.newval = 'newval';
$scope.$watch('group.name', function(newval, oldval) {
if (newval == $scope.newval) {
$scope.displayDiv = true;
}
}
and for the HTML :
<div class="col-md-4" ng-show="displayDiv">
Here's a working example.
First we set up our options and input.
<select ng-model="curopt"
ng-options="option.name for option in options">
</select>
<input type="text" ng-model="newopt"
ng-show="curopt.name == 'New'"
ng-keypress="newOption($event)">
The ng-show option for our input is tied to the name of the currently selected option. We also add an ng-keypress directive to allow us to handle the enter key being pressed.
Now to the controller...
$scope.newOption = function(event) {
if (event.which == 13) {
$scope.options.push({ name : $scope.newopt, value : $scope.newopt });
$scope.newopt = '';
}
}
Because our select input options is tied to the $scope.options we can simply append our text inputs value to the array and angular will handle updating for us due to data binding.
I'm developing an app in mobile-angular-ui (angular+bootstrap).
In my login page, users can remember their credentials (username and password). Users' data ara saved in the localStorage.
That works fine. I can load users in my login page using datalist:
<form name="userForm">
<div class="form-group" ng-class="{ 'has-error' : submitted && userForm.username.$invalid && !userForm.username.$pristine }">
<label for="inputEmail" class="control-label">Username</label>
<input type="text" class="form-control" id="inputEmail"
name="username" ng-model="user.username" list="UserMemoList"
required>
</div>
<datalist id="UserMemoList">
<option ng-repeat="item in userMemoList track by $index" ng-click="setChange(item)"
value="{{item.username}}" >
</option>
</datalist>
I can select the item.username I want, but I'm not able to select the corresponding item.password.
My problem is that datalist doesn't work like select, and i cannot use ng-options. I have to use option+value to pass my value to the input.
<div class="form-group" ng-class="{ 'has-error' : submitted && userForm.password.$invalid && !userForm.password.$pristine }">
<label for="inputPassword" class="control-label">Password</label>
<input name="password" type="password" class="form-control" id="inputPassword"
ng-model="user.password" required>
</div>
I would be able to use a ng-change="theSelectedUserIs(item)", but I'm not able to pass the item object, because datalist is related to the username input, so I need to pass item.username.
Any idea?
I don't want to use typeahead because actually is deprecated in bootstrap3 or add other libraries/js/css.
I would like to do that only using angular and html.
My controller:
$scope.userMemoList = JSON.parse(localStorage.getItem('userList'));
var user = {};
LoginService.setUser(user);
userMemoList is an array of object like:
{"username":"admin", "password":"admin"}, ...
Thanks.
You can also pass with html data-id like so
in your angular js file
// when input name textbox change, check the value is same with datalist value or not. If value same, then bind that item.password to angular password model.
$scope.$watch "user.username", (newValue) ->
if newValue != null && newValue.lenght > 0
$("#locationlist option").each (index) ->
if $(this).val() == newValue
$scope.user.password = $(this).data("id") // this line will set your password text field
in your view
// pass user password via html5 (data-id) element like below
<datalist id="UserMemoList">
<option ng-repeat="item in userMemoList track by $index" ng-click="setChange(item)"
value="{{item.username}}" "data-id" = {{item.password}} >
</option>
</datalist>
This is how I solved this problem in my app. Use to wrap .
<input class="input form-control" placeholder="Search Conf by Application ID"
list="app_ids" ng-model="confs_app_id"/></th>
<datalist id="app_ids">
<select>
<option ng-repeat="app in app_list" value="{{app}}"></option>
</select>
</datalist>
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>
