I am new to FormGroup, so I guess I making some very silly mistakes, but I am not able to figure out where.
I have designed this below UI:
Now, as it can be seen, there are 3 checkboxes under Select Server Option. So, what I want is on click of the Download button, to submit the values of the checkbox.
What I have tried till now is as shown here:
this.systemlogsform = this.fb.group({
logtype: ['installlogs', Validators.required],
servers: [[], Validators.required]
});
getServiceListData(type) {
this.nodeList = [];
this.apiservice.getClusterInfo()
.subscribe(data => {
if (Array.isArray(data.NodeList)) {
this.nodeList = data.NodeList;
} else {
this.nodeList.push(data.NodeList);
}
})
}
The below is the html code:
<div class="large-12 small-12 medium-12" *ngIf="systemlogsform.value.logtype==='installlogs'">
<div>
<label class="col-md-12 md-padding--s md-padding__left--l md-padding__top--s" for="" formGroupName="systemService"><strong>
Select Server Option
</strong></label>
<div
class="col-md-3"
*ngFor="let node of nodeList; let j=index;"
>
<md-checkbox
style="padding-left:45px;"
name="TDG"
value="{{node.FQDN}}"
label="{{node.FQDN}}"
htmlId="{{node.HostName}}"
[formControl]="node"
[formControlName]="j">
</md-checkbox>
</div>
</div>
</div>
The checkbox values will be coming from an api call. So, I can not hard code the values in the form group.
1) So, how do I submit multiple values of the checkbox if more than 1 of them are clicked.
2) Also, I am facing issue in retrieving the value of the checkbox, can someone please help me with this.

I have a ng-repeat that loops over 9 divs, each one has a different color.
When the user clicks on one div, its color it's gonna be the background color of a section.
I'm trying to do this:
The array that gets repeated is structured like this:
interface colorBoxes {
color: string;
isSelected: boolean;
}
in the view:
<div ng-repeat="s in vm.colorBoxes track by $index">
<div class="pointer" ng-click="w.backgroundColor = s.color; vm.pickColor(s, $index)" ng-style='{"background-color": s.color}'>
<i ng-show="vm.isColorSelected($index) === true" class="fa fa-check fa-1x checkOnSelectedLegend"></i>
</div>
</div>
in the controller:
pickColor(array: any, index: number) {
for(var i = 0; i<=this.colorBoxes.length; i++) {
this.colorBoxes[i].isSelected = false;
}
array[index].isSelected = true;
}
I use this function so when you click on a DIV, its variable: isSelected gets true, and all the other DIV's have theirs set to false.
I use this variable in the view with a ng-show, to show a check mark on the DIV that is currently selected, but this isn't working, below the function I put in that ng-show
isColorSelected(index:number):boolean {
return this.colorBoxes[index].isSelected
}
What am I doing wrong?
To summarize, I want that when you click on a box, its color string gets applied to another element (that is working correctly with my code), then, that box need to have a check mark appear on top of it, I tried with the above functions, by setting the isSelected var to true when clicked, but it doesnt work.
I'm pretty sure the problem is that angular isn't checking for changes in that ng-show, I just don't know exactly how to make it check for changes, and maybe there is a cleaner way to obtain what I'm trying to do!
Thank you

Ok, here you have your code fixed and working:
http://jsfiddle.net/7zymp2gq/4/
Basically there were 2 things wrong with the function $scope.pickColor:
The loop was entering into not existing fields, I have changed the <= with a <
It was updating array[index], and it should be updating $scope.colorBoxes[index]
Instead of using function at ng-show you can use the isSelected property:
<div ng-app="app" ng-controller="Ctrl">
<div class="class1" ng-repeat="s in colorBoxes track by $index">
<div class="pointer class2" ng-click="pickColor(colorBoxes,$index);" ng-init="lastselected=s.isSelected?$index:null" ng-style='{"background-color": s.color}'>
<i ng-if="s.isSelected" class="fa fa-check fa-1x checkOnSelectedLegend"></i>
</div>
</div>
<div class="changeColor" ng-style='{"background-color": chosenColor}'></div>
</div>

Just starting out learning AngularJS and decided to mock up a basic product gallery using what I've learned so far and I've hit a roadblock. Currently I have a simple product gallery with 3 templates(category listing, products in category listing and product overview). What I would like to do is set up some sort of conditional, where if the products in a selected category have a sub-category, it displays a list of sub-categories using the category-list template. If they don't have a sub-category it just goes straight to the product-list template.
I have created this Plunker showing where I am at so far.
In the above example, if someone clicks on "Cars" I want it to then show a listing of sub-categories using the category-list template. So when you click "Cars" it would take you to a screen with 2 buttons: 4-door and 2-door. Clicking on one of those buttons would then show you the products from those sub-categories using the product-list template. However, if you were to click on "Trucks" from the initial screen, it would just take you directly to the product-list template since the trucks don't have sub-categories.
Here is my category-list template:
<section id="categories" ng-hide="productsVisible">
<div ng-repeat="product in vm.products" class="category">
<div ng-click="vm.selectCategory(product); showProducts();">
<button>{{product.category}}</button>
</div>
</div>
</section>
And here is my product-list template:
<section id="products" ng-show="productsVisible">
<div ng-repeat="product in vm.selectedCategory.items" class="product">
<a href ng-click="vm.selectProduct(product); showResults();">{{product.name}}</a>
</div>
</section>
See my updated plunker
Basically, you need to extend the selectCategory method by grouping the sub-categories and checking whether we're about to enter this sub-category in subsequent click. Like this:
vm.selectCategory = function(category) {
var subCats = [],
map = {};
if (category.items && !category.items[0].subCategory){
vm.selectedCategory = category;
vm.inSubCat = true;
return;
}
vm.inSubCat = !category.items;
if (category.items) category.items.forEach(function(e){
if (!map[e.subCategory]) subCats.push({category: e.subCategory, name: category.category});
map[e.subCategory] = true;
});
vm.products = subCats;
if (vm.inSubCat) vm.selectedCategory = {items: vm.data.filter(function(c){
return c.category == category.name;
})[0].items.filter(function(p){
return p.subCategory == category.category;
}) };
}
I would suggest your data model could use some work, and put all the products in a single array with categories and subcategories as properties. However, you can get what you want with this change to the products-list.html.
<div ng-show="vm.selectedCategory.category=='Cars'">
<input type="radio" ng-model="subcategory" value="2-Door">Coupe
<input type="radio" ng-model="subcategory" value="4-Door">Sedan
</div>
<section id="products" ng-show="productsVisible">
<div ng-repeat="product in vm.selectedCategory.items" class="product">
<a ng-show="product.subCategory===subcategory" href ng-click="vm.selectProduct(product); showResults();">{{product.name}}</a>
</div>
</section>
I advice you to refactor the code in two possible ways:
a) Try to remove lines from controller that control the view (the process of displaying different directives) and use events in directives
b) Control your view by using ng-show and ng-hide directives that will show or hide some part of your code.
Im using ionic framework and Im trying to create a phone list which can add and delete the user entered phone no.Here the user entered numbers are listed with check box on clicking the add button.When the user selects the check-box and clicks the delete button, he must be able to delete the selected check box phone number.Here the problem is while using the delete button, it doesn't delete the selected check box instead it is deleting the first value entered in the list. So please help me to delete only user selected check-box items.
html code:
<div>
<ion-checkbox ng-model="phoneno" ng-repeat="y in phonelist">
<span data-ng-bind="y"> {{y}}</span> </ion-checkbox>
<button ng-click="remove($index)" value="Delete">Delete</button><br>
</div>
<br>
<br>
<div>
<!label class="item item-input item-floating-label">
<input ng-maxlength="10" ng-model="phone"> <br>
<button ng-click="add()" value="Add">Add</button><br>
<!/label>
</div>
</ion-content >
</ion-view>
js code:
.controller('PlaylistCtrl', function($scope, $stateParams) {
})
.controller('addAdmin',['$scope',function($scope){
$scope.phonelist=[];
$scope.add=function(phone){
$scope.phonelist.push($scope.phone);
$scope.phone='';
}
$scope.remove=function(uuid){
var x=$scope.phonelist[uuid];
$scope.phonelist.splice(uuid,1);
}
}]);
Sorry for my english. I'm foreigner..
The problem is that your loop ends before the button, so when the button gets clicked the $index is always 0.
Because its not inside the element "ion-checkbox".
Here is my solution: put ng-click inside the checkbox and call to function with the $index.
And in the js, save the index on a scope var. So if the delete button gets clicked, delete the index that you saved on the previous function.
I hope that i helped.
It seems like you mean something else than your code says. You probably want to delete all phones that are checked, when clicking the button. Therefore you don't need the $index property, but just loop through the phones and delete the ones that are checked.
You will have to keep track of a 'checked' property of each phone, so you know which are checked. You can do this by using an object which holds the phone information, instead of just a string:
<div>
<!-- ng-model to a property of the phone that keeps track if the phone is checked -->
<ion-checkbox ng-model="y.checked"
ng-repeat="y in phonelist">
<span data-ng-bind="y.number">{{ y.number }}</span>
</ion-checkbox>
<button ng-click="removeSelected()" value="Delete">Delete</button><br>
</div>
<!-- ng-model to a property of the phone object -->
<input type="text" ng-model="phone.number" />
And in your controller:
$scope.add = function() {
$scope.phonelist.push($scope.phone);
}
$scope.removeSelected = function() {
var i = $scope.phonelist.length;
// reversed loop because you change the array
while (i--) {
var phone = $scope.phonelist[i];
// If phone is checked, remove from list
if(phone.checked) {
$scope.phonelist.splice(i, 1);
}
}
}
See this jsfiddle
Or see this jsfiddle where I included Ionic
It seems that you're mixing the add and remove functions, try to separate those as below.
.controller('addAdmin',['$scope',function($scope){
$scope.phonelist=[];
//Add function
$scope.add=function(phone){
$scope.phonelist.push(phone);
$scope.phone='';
}
//Remove function
$scope.remove = function(index){
$scope.phonelist.splice(index, 1);
};
}]);
add the following code in your controller
$scope.remove = function(index){
$scope.phonelist.splice(index, 1);
}
and that should work
I started to work with Angular, it's pretty good to implement, I stuck with a single issue at ng-click
I am getting data dynamically and showing with ng-repeat, and I want to update the data at pencil click and for it I am using input text element, but when I click on pencil It's opening all the text fields
Here is my HTML code
<
div ng-repeat="item in scroller.items track by $index">
<div class="secHead text-center">
<button class="common btnDarkGrey" data-ng-hide="hideCatButton">{{item.category_name}}</button>
<input type="text" id="focus-{{$index}}" class="common btnDarkGrey editDashboardCategory" name="editCategory" value="" data-ng-model="item.category_name" data-ng-show="hideField">
<span data-ng-click="updateCategory(item.category_id,item.category_name,$index)" class="chkOneDone" data-ng-show="hideOkButton">Done</span>
<div class="pull-right">
</div>
</div>
</div>
And here I Angular code
$scope.updateCategory=function(category_id,updated_cat_name, $index){
Category.updateCat($rootScope,$scope,$index,$http,$timeout,updated_cat_name,old_cat_name,category_id);
};
$scope.updatePen=function($index){
old_cat_name=$scope.scroller.items[$index].category_name
$scope.hideField=true;
$rootScope.hideOkButton=true;
$rootScope.hideCatButton=true;
};
I created a Category service to perform task like update
I didn't get any proper solution yet.
Can anybody help me?
Thank You.
If you only want to hide/show one of the elements in the list you need to specify that in some fashion. Right now you have a three rootScope booleans:
$scope.hideField=true;
$rootScope.hideOkButton=true;
$rootScope.hideCatButton=true;
being set for the entire list, and you need to set a show properties on each individual in the list.
In your controller function you can do something like this before you expect a click:
//normal for loop so that you have the index
for(var i=0; i < $scope.scroller.items.length; i++){
$scope.scroller.items[i].show = false;
}
Then you can do something like this to actually show the fields:
HTML:
div ng-repeat="item in scroller.items track by $index">
<div class="secHead text-center">
<button class="common btnDarkGrey" ng-hide="!item.show">
{{item.category_name}}</button>
<input type="text" id="focus-{{$index}}" class="common btnDarkGrey editDashboardCategory" name="editCategory" value="" ng-model="item.category_name" ng-hide="!item.show">
<span data-ng-click="updateCategory(item.category_id,item.category_name,$index)" class="chkOneDone" ng-show="item.show">Done</span>
<div class="pull-right">
</div>
</div>
</div>
Controller:
//controller declaration --
$scope.updatePen = function(index){
$scope.scroller.items[index].show = true;
};
It's my understanding that you need all three properties to show once a click happens, so I condensed all the show properties into one single show property.
Your view only sees that hideField is true and performs that action for all of the items in your array. I hope this helps!
Am successful in building angularjs app of multiple dependent radio button.
But have a requirement to default select a radio button if only one is present.
Tried out the stuff in Angularjs: radio button checked, but it doesn't work for multiple radio buttons.
Code Explanation:
HTML Code:
I have two radio buttons. Second set of radio buttons are generated based on the first.
<div>
<ul >
<li> Part One : </li>
<li ng-repeat="f in Input"><input type="radio" name="oneInput" ng-value="f" ng-model="$parent.One"> {{f.Name}} </input></li>
</ul>
</div><br/>
<div>
<ul>
<li> Part Two : </li>
<li ng-repeat="u in filteredUser = (One.User | filter: { Valid: 'Y' })"><input type="radio" name="userInput" ng-value="u" ng-model="$parent.Two"> {{u.Name}} </input></li>
</ul>
</div><br/>
If I select a radio button in first set, and second set has only one radio button, it must be selected by default.
For example, if I select D, I get the D2 radio button which must be selected.
