I am new to angular and I'm confused over this thing. I'm trying to populate a select box based on object inside an array. I want selectbox by using ng-repeat for that array... but initially i need to show only one selectbox after clicking add() next selectbox has to come. for ref:[initially one selectbox has to come]
HTML
<div class="col-lg-12" id="variant1" style="margin-top:10px" ng-repeat="variant in variants">
<div class="col-lg-4" style="text-align:right;padding-top:2px;padding-right: 20px" >
<label for="variant1name">Variant Name</label>
</div>
<div class="col-lg-6" >
<div >
<select class="form-control" ng-model="filterFormInputs.apps" ng-options="app.Application for app in variants" >
<option value="" disabled selected>Select an Application</option>
</select>
<label ng-repeat="checkbox in filterFormInputs.apps.details">
<input class="ecomtexttype1" type="checkbox" ng-model="checkbox.checked"> {{checkbox.name}}
</label>
</div>
</div>
</div>
Controller:
$scope.variants =
[
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]},
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]},
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]}
]
I think that you can just have your add() function update the array... if things are configured correctly the new row should render due to the binding on the array.
As mentioned in comments you did not provide enough source code, so here is the assumed pseudo-code:
in html you might have
<button ng-click="$scope.add()">Add</button>
so in the controller
$scope.variants = [
// array of whatever you are displaying
{"foo":"bar1"},
{"foo":"bar2"}
];
$scope.add = function() {
variants.push({"foo":"bar_new"});
}
Have you considered using a Directive for this? That may work better, depending on your situation. Look into this: https://docs.angularjs.org/guide/directive

I have multiple select with different values. When the user selects the options that he wishes, press add button and must be added as elements to an array and that new line of added options be displayed in the view.
This does not work correctly, since each new selection steps on the values of the previous one. Only the last chosen option prevails. Example of my wrong array of values:
[{"product":"Product3","type":"A"},{"product":"Product3","type":"A"},{"type":"Product3","type":"A"}]
Here is my code:
<div class="col-md-3">
<label for="product" class="control-label">Product</label>
<select class="form-control pull-right" name="product" ng-model="data.product" >
<option ng-repeat='(key,value) in productList' value="{{key}}">{{value}}</option>
</select>
</div>
<div class="col-md-3">
<label for="type" class="control-label">Type</label>
<select class="form-control pull-right" name="type" ng-model="data.type" >
<option ng-repeat='i in typeList' value="{{i}}">{{i}}</option>
</select>
</div>
<button type="button" class="btn" ng-click="addElements()" >Add</button>
<div class="col-md-3">{{elementsList}}</div>
And in my angular controller:
$scope.elementsList = [];
$scope.addElements = function() {
$scope.elementsList.push($scope.data);
}
What's my problem? I am new in angular and js and it is difficult for me to see it ... how can I add and remove elements dynamically? Thanks!
When you add the $scope.data object to the array in addElements, it adds a reference to that object because that's how Javascript objects are stored: by reference. What that means is that any time that $scope.data changes in the future, the value you see in the array will also change. So you can do something like this instead:
$scope.addElements = function() {
const clone = Object.assign({}, $scope.data);
$scope.elementsList.push(clone);
}
This creates a new object clone each time.
I have a <select> in my application, which is supplied data from an ng-repeat but each option in the select has data of it's own. Simply enough, here is the JSON payload I am working with:
{
"0":{
"name":"Mover",
"scalar":[
{
"name":"Size",
"unit":"m"
},
{
"name":"Speed",
"unit":"m/s"
}
]
},
"1":{
"name":"Stationary",
"scalar":[
{
"name":"Size",
"unit":"m"
}
]
},
"2":{
"name":"Vibrator",
"scalar": [
{
"name":"Frequency",
"unit":"hz"
}
]
}
}
I need the outer 3 names in the select, but I'd like the 'scalar' values to show up as checkboxes next to the select. It's obviously got to be dynamic, so i was curious if there was a way to do this based off of the ng-repeat of the select. Another reason why I am asking is because due to formatting, I'd like to place the checkboxes outside of the ng-repeat (clearly since that's in a select) so not too sure how the checkboxes would access the repeat value. Below is the html snippet:
<div id="type-selection"
class="row ng-hide"
ng-show="rcw.page ==='Type Selection'">
<div class="col-md-6">
<div class="form-group">
<label for="rule-type">Type</label>
<select id="rule-type"
class="form-control"
ng-model="rcw.selectedRuleType">
<option ng-repeat="type in rcw.QueryTypes">{{type.name}}</option>
</select>
</div>
</div>
<div class="col-md-2" ng-repeat="ideally scalar in type from above^">
<label>
<input type="checkbox"
class="faChkSqr"
ng-model="ideally this would be dynamically tied to scalar.name </input>
<span></span>
<b>{{ideally this would be scalar.name}}</b>
</label>
</div>
</div>
Just not too sure if this is possible, or if I need to handle what's selected then from there in the javascript decide what needs to be displayed? Thanks in advance!
You are storing the selection in a variable: rcw.selectedRuleType
<select id="rule-type" class="form-control" ng-model="rcw.selectedRuleType">
<option ng-repeat="type in rcw.QueryTypes">{{type.name}}</option>
</select>
I guess you just have to loop over this object with your ng-repeat:
<div class="col-md-2" ng-repeat="scalar in rcw.selectedRuleType">
{{scalar.name}}
</div>
As a side note, I suggest you to use ng-options in your select:
<select ng-model="rcw.selectedRuleType"
ng-options="type as type.name in rcw.QueryTypes">
</select>
Try like this.
<li ng-repeat="n in items">{{n.name}}{{n.scalar}}
<select ng-model="selectme" ng-options="options.name for options in n.scalar">
<option value="">-- choose color --</option>
</select>{{selectme}}
</li>
We can create checkboxes based on the selection,But not sure how we can dynamically bind model based on scaler.name.
We need to set the value of option as scaler of selected option.Then we should listen to change event on select field & extract the scalar value from the selected value.
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.QueryTypes = [{
"name":"Mover",
"scalar":[
{
"name":"Size",
"unit":"m"
},
{
"name":"Speed",
"unit":"m/s"
}
]
},
{
"name":"Stationary",
"scalar":[
{
"name":"Size",
"unit":"m"
}
]
},
{
"name":"Vibrator",
"scalar": [
{
"name":"Frequency",
"unit":"hz"
}
]
}
];
$scope.getScalarTypes=function(){
$scope.scalarTypes=JSON.parse($scope.selectedRuleType);
}
});

This problem has been frustrating me for the last couple days now so, here I am. I'll try to be as clear as possible.
I have an object to retrieve from the database. This object is used to create dropdown menus. It has two properties on it: A section property, which contains one string. The other property is called value, which contains all the possible options that the user can select in the dropdown. I use two nested ng-repeats in my HTML to create the dropdowns.
I am trying to send out to the database a formData object that has 2 properties in it: the name of the dropdown menu, and the value that the user selected. Appending the value selected from the dropdown menu is easy thanks to two way data binding that I set on the select element. However, I CANNOT figure out how to grab the value from the label element inside my controller so that I can attach it to my formData object. As far as I know, ng-model does not work on a label element. Here is the HTML, which hopefully will make it a bit more clear:
<form class="form-horizontal" ng-controller="PreferenceCtrl">
<div ng-repeat="(name, section) in configs">
<label ng-bind="name"></label>
<select class="form-control" ng-model="formData.settings[$index].value">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
</option>
</select>
</div>
<div class="col-md-12" ng-include="gametemp"></div>
<div class="row">
<div class="hr-line-dashed"></div>
<div class="text-center col-md-12 padding-15">
<button class="btn btn-primary btn-lg" ng-click="saveSetting()" formnovalidate translate>
<i class='fa fa-circle-o-notch fa-spin' ng-if="showBusy"></i> Save
</button>
</div>
</div>
</form>
Because the <select> class can have an ng-model attached to it, I can easily capture that value in my controller. I cannot do the same with the label. If anyone can help me out I will forever be your best friend. Thank you!
In answer to your question title "Is there a way to create a two-way binding on a label element", no, that isn't possible.
But if I understand correctly what you're trying to do, it sounds like you want to save data to the database based on information contained in both the <label> and it's associated <select>. If that's true, then I'd recommend using an ng-change function in your <select> like this:
<select class="form-control" ng-model="formData.settings[$index].value" ng-click="dropdownItemClicked(name, formData.settings[$index].value)">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
</option>
</select>
In your controller, create a function to handle this ng-click event:
$scope.dropdownItemClicked = function(name, value) {
console.log(name, value);
// save name/value to database
}
The key is to pass in the exact data you want to save to the database into your dropdownItemClicked() function.
Could you just put the value inside the label?
<label ng-bind="name">{{formData.settings[$index].value}}</label>
There is no way to read from the label. It is the one way binding after all, right. I would do something like this.
var app = angular.module('MyApp', []);
app.controller("MyCtrl", function($scope){
$scope.formData = {
settings:[]
};
$scope.configs = {
'Label1': [{ value: 11 }, { value: 12 }],
'Label2': [{ value: 21 }, { value: 22 }]
};
$scope.change = function(name, idx) {
$scope.formData.settings[idx].name = name;
};
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<div ng-cloak="" ng-app="MyApp">
<form class="form-horizontal" ng-controller="MyCtrl">
<div ng-repeat="(name, section) in configs">
<label ng-bind="name"></label>
<select class="form-control" ng-model="formData.settings[$index].value" ng-change="change(name, $index)">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
{{item.name}}
</option>
</select>
</div>
<div class="col-md-12" ng-include="gametemp"></div>
<div class="row">
<div class="hr-line-dashed"></div>
<div class="text-center col-md-12 padding-15">
<button class="btn btn-primary btn-lg" ng-click="saveSetting()" formnovalidate translate>
<i class='fa fa-circle-o-notch fa-spin' ng-if="showBusy"></i> Save
</button>
</div>
</div>
<div>
{{formData.settings}}
</div>
</form>
</div>
I have a nested Objects in JSON, and I need to populate the checkbox based on what comes in (dynamic) from JSON file, meaning, I wouldn't know in advance the name of the fields, or how many elements there could be. Here is a sample, but there could be more child and each child could have more or less item in it.
{
"Parent":{
"Child" :
{
"Child_01" : {
"description_01":false,
"description_02":false,
"description_03":false,
"description_04":false,
"description_05":false
},
"Child_02" :
{
"something_01":false,
"something_02":false,
"something_03":false,
"something_04": false
},
"Child_03" :
{
"things_01":false,
"things_02":false,
"things_03":false,
"things_04":false,
"things_05":false
}
}
}
}
Now, I need to populate a drop down from it, (child_01, child_02, child_03....) and when user choose one of them, I need to display checkboxes of all its properties. And of course be able to keep track of the chosen one.
Here is what I have.
$scope.children = response.data.parent.child;
$scope.childrenList = [];
angular.forEach($scope.children, function(value1, key1){
$scope.childrenList.push(key1);
});
and html:
<div ng-repeat="(key, data) in children">
<input ng-model="childrenListModel" type="checkbox" name="{{child}}" value="{{child}}">{{child}}</input>
</div>
Nothing works the way I intend to. Any help would be appreciated.
You probably need several nested ng-repeats. Have a look at this working plunker: http://plnkr.co/edit/K92JI7UlW9h6gh8SPeU5?p=preview
<div ng-repeat="child in children.Parent.Child">
<div ng-repeat="options in child">
<div ng-repeat="option in options">
<div ng-repeat="(key, val) in option">
<label for="{{key}}">
{{key}}
<input name="{{key}}" type="checkbox" ng-model="option[key]" />
</label>
</div>
</div>
<hr />
</div>
</div>
I am generating dropdown at runtime using AngularJs. I also want to bind corresponding options with it which will be generated based on dropdown type being created.
<div class="form-group" ng-repeat="attrib in col1Attribs">
<label class="control-label" for="txtCode">{{attrib.displayText}}</label>
<select class="form-control"
ng-options="item.configValue for item in configOptions(attrib.configType)" />
</div>
My controller has following method.
$scope.configOptions = function (type){
return SmartCache.get(type); //SmartCache is my cacheFactory
}
EDIT:
Here is my data when parameter type = 'Status'
[{"$id":"1","people":[],"configId":"STAT001","configValue":"Active","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Active","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHM=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"2","people":[],"configId":"STAT002","configValue":"Suspended","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Suspended","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHQ=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"3","people":[],"configId":"STAT003","configValue":"Terminated","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Terminated","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHU=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"4","people":[],"configId":"STAT004","configValue":"Deleted","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Deleted","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHY=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]}]
I am able to achieve my task using code below but not using ngOptions.
<div class="form-group" ng-repeat="attrib in col1Attribs">
<label class="control-label" for="txtCode">{{attrib.displayText}}</label>
<select class="form-control">
<option ng-repeat="c in configOptions(attrib.configType)" value="{{c.configId}}">
{{c.configValue}}</option>
</div>
</div>

I can't see the rest of your code. Here is a snippet of how to create the dropdown:
<select data-ng-options="e.description for e in configOptions" data-ng-model="selectedOption" />
Demo:http://plnkr.co/edit/YcuqZ1gs4iDAAgfLrZPO?p=preview
Probably you are trying this
Use as
<select class="form-control"
ng-options="item.configId as item.configValue for item in configOptions(attrib.configType)" />
configId adds as option value and configValue as display value.
