For some reason AngularJS does not fire off the event when {{$index}} is used in ng-click.
My html:
<div ng-controller="Ctrl">
<ul>
<li ng-repeat="foo in foos">
<label>{{foo.name}}</label>
X (doesnt work)
Remove first element (works)
</li>
</ul>
</div>
jsfiddle: http://jsfiddle.net/Lcasg/3/
Anyone knows how to fix this? Thanks
The value of the ng-click attribute is evaluated as an angular expression, so simply use remove($index).
solved!
<div ng-repeat="idiomax in textos.idiomas ">
<div class="idioma" ng-click="cambiaridioma($index)" ng-class="idioma != $index || 'idioma-activo'" >
{{idiomax.idioma}}
</div>
</div>
$scope.cambiaridioma = function (indice) {
$scope.idioma = indice;
}
I had to use $index in a string expression and this is how it worked:
HTML
<button ng-click="showUserStories($event, '#modal-id-prefix-' + $index)">Show Modal</button>
Script
$scope.showUserStories = function(event, modalId) {
$(modalId).modal("show");
event.stopPropagation();
}

I have following code and try to use $index in delete function but it gives incorrect value of it.
<li ng-repeat="joinMember in data.teamMember | orderBy:'member.screenName || member.fname' ">
<div class="member-list-img">
<a ng-href="">
<img ng-src="{{joinMember.member.data.image ? (joinMember.member.data.imageType == 'avatar' ? '/public/images/avatars/' + joinMember.member.data.image : '/public/images/' + joinMember.member.data.image) : '/public/images/avatars/avatar-73.png'}}" width="100%" alt="{{joinMember.member.screenName ? joinMember.member.screenName : joinMember.member.fname + ' ' + joinMember.member.lname }}" />
</a>
</div>
<div class="member-list-cont">
<h4>
<a ng-href="#">
{{joinMember.member.screenName ? joinMember.member.screenName : joinMember.member.fname + ' ' + joinMember.member.lname }}
</a>
</h4>
<span>{{joinMember.created | date : "MMMM d, y"}}</span>
</div>
<div ng-if="data.canModify" class="membr-delete">
<a ng-href="">
<i class="fa fa-trash text_link" aria-hidden="true" ng-click="deleteTeamMember($parent.$index, joinMember.id)"></i>
</a>
</div>
</li>
That's because the directive ng-if creates a new scope for itself, when you refer to $parent, it access the immediate $parent's scope, i.e., the inner repeat expression's scope.
So if you want to achieve something you wanted like in the former, you may use this:
<div ng-repeat="i in list">
<div ng-repeat="j in list2">
<div ng-if="1">
({{$parent.$parent.$index}} {{$parent.$index}})
</div>
</div>
</div>
if you have more than one inner directives, you can use ng-init for storing $index in a variable for references in child scopes.
<div ng-repeat="i in list" ng-init="outerIndex=$index">
<div ng-repeat="j in list2" ng-init="innerIndex=$index">
<div ng-if="1">
({{outerIndex}} {{innerIndex}})
</div>
</div>
</div>
So try $parent.$parent.$index in your example and please check understanding the scopes
You are using $parent.$index in a div that have ng-if tag. which delete dom element(div) if condition is fall so that case you will receive incorrect $index value. but with ng-show it only add hide class to that div.
So try to ng-show if it is not important to remove div element instead just hide it.
Note:- You are also using orderBy filter in ng-repeat which will sort in only your DOM so if you will find incorrect object value in your controller.
As you can see in the official documentation of angularjs you should get a zero-based index via $index within a ng-repeat. Try the example by angularjs here. Try to debug data.teamMember in your controller to make sure that this is the correct array you'd like to iterate.
I have a loop ng-repeat that displays sevral icons.
<div class="box">
<div class="box-body">
<div class="row" >
<div class="col-sm-6" style="margin-bottom: 5px;" ng-repeat="record in newlayout.display" align="center">
<a class="btn btn-app" ng-href="#newlayout/{{newlayout.url}}{{newlayout.itemValue}}" >
<span class="badge bg-yellow" style="font-size:22px;">{{record.numberOfSamples}}</span>
<i class="fa fa-{{newlayout.labStyle}}"></i> {{record.lab}}
</a>
</div>
</div>
</div>
</div>
My issue is that the second part of the binded variable itemValue should be dynamic
In my Js, I have this
newLayout.url = 'sublabs/?labName=';
newLayout.itemValue = 'record.lab';
The URL is dynamic.
When I click on the first displayed Icon, the url should look like this :
But it didn't work as I had a compilation error..
Does someone have an idea how to fix this:
http://localhost:8181/#/newlayout/sublabs?labName=PIA/C1 - Shiftlabo
Where the record value "PIA/C1 - Shiftlabo" change.
So basically here if I change
<a class="btn btn-app" ng-href="#newlayout/{{newlayout.url}}{{newlayout.itemValue}}" >
{{newlayout.itemValue}} by {{record.lab}} it would work..but the {{record.**lab**}} should be dynamic as it will have another value when I click on the icon. It will change to {{record.subLab}}
Thanks
Use property acccessor bracket notation inside the binding:
<div>{{record[labOrSublab]}}</div>
JS
var isSublab = false;
$scope.labOrSublab = "lab";
$scope.clickHandler = function() {
isSublab = !isSublab;
$scope.labOrSublab = isSublab ? 'subLab' : 'lab';
};
I'm using angular 1.4.8. I want to save filtered result from ng-repeat and use it to determine whether to enable a "load more" button at the bottom of the list. I have looked at this question:
AngularJS - how to get an ngRepeat filtered result reference
And many others, they suggest to use "as alias" from ng-repeat, here's what my code looks like:
<ul class="media-list tab-pane fade in active">
<li class="media">
<div ng-repeat-start="item in items | limitTo: totalDisplayed as filteredResult">
{{item}}
</div>
<div class="panel panel-default" ng-repeat-end>
</div>
<div>
{{filteredResult.length}}
</div>
</li>
</ul>
<button ng-click="loadMore()" ng-show="totalDisplayed <= filteredResult.length">
more
</button>
However, I found filteredResult.length is displayed fine right after ng-repeat, but the button is never shown. If I try to display filteredResult.length in where the button is, it will show null.
So is there a rule for "as alias" scope? I've seen plenty of examples work but mine doesn't, what am I missing here?
EDIT:
The accepted answer uses controllerAs which indeed will resolve the problem. However, charlietfl's comment using ng-init to save filteredResult to parent scope is also very neat and that's the solution I use in my code eventually.
Probably some of classes in your <ul class="media-list tab-pane fade in active"> or <li class="media"> is selector for a directive that would have its own scope. So you store filteredResult in e.g. tab-pane's scope and then try to have access out of it's scope in outside of ul tag.
Try to use Controller as instead of scope:
angular
.module('plunker', [])
.controller('MainCtrl', function() {
vm = this;
// make an array from 1 to 10
var arr = [];
while (arr.length < 10) {
arr.push(arr.length + 1)
};
vm.items = arr;
vm.totalDisplayed = 5;
vm.filteredResult = [];
});
<body ng-controller="MainCtrl as main">
{{main.items}}
<ul class="media-list tab-pane fade in active">
<li class="media">
<div ng-repeat-start="item in main.items | limitTo: main.totalDisplayed as filteredResult">
{{item}}
</div>
<div class="panel panel-default" ng-repeat-end>
</div>
<div>
filteredResult = {{main.filteredResult = filteredResult}}
</div>
</li>
</ul>
<button ng-click="loadMore()" ng-show="main.totalDisplayed <= main.filteredResult.length">
more
</button>
</body>

I know that this question has already some answers/solutions but none of them works for me most probably because this is the first time when I'm trying to implement something using Angularjs.
I have a div (title) that expands some info when it's clicked and I want to change the icon inside of it when that info is visible...
This is my code:
<div class="title" ng-click="view_variables(request)">
<i class="glyphicon glyphicon-chevron-right"></i>
</div>
And this is what I tried to do, but not working because the div will not show the expanded info anymore:
<div class="title" ng-click="view_variables(request) = !view_variables(request)">
<i ng-class="{'glyphicon glyphicon-chevron-right':!view_variables(request), 'glyphicon glyphicon-chevron-left': view_variables(request)}"></i>
</div>
Controller code:
$scope.view_variables = function(req){
if (!req.enabled_variables && !req.disabled_variables) {
$http.get('/api/files/' + $scope.file_id + '/requests/' + req.id + '/variables')
.success(function(data){
variables = data.data;
req.enabled_variables = [];
req.disabled_variables = [];
for (i=0; i<variables.length; i++) {
if (variables[i].disabled == true) {
req.disabled_variables.push(variables[i]);
} else {
req.enabled_variables.push(variables[i])
}
}
});
}
req.show_variables = !req.show_variables;
}
The view_variables function doesn't return anything, so it will always be treated as false.
You want something like this:
<div class="title" ng-click="view_variables(request)">
<i ng-class="{'glyphicon glyphicon-chevron-right':!request.show_variables, 'glyphicon glyphicon-chevron-left': request.show_variables}"></i>
</div>
I think the problem is what you have going on in the ng-click attribute. By using "view_variables(request) = !view_variables(request)" are you not calling the view_variables function twice? Also, it seems strange to be assigning a value to a function call.
I would just keep ng-click="view_variables(request)" as you had in the first line of code, then have the view_variables function set a boolean somewhere in scope ($scope.data.view_vars) and have that determine ng-class for your i element.
Good luck!
--EDIT: Now that you've put up your controller, req.show_variables looks like a useful candidate
Calling a function inside ng-class is a bad idea. Why don't you use a flag for it.
eg.
inside controller-
$scope.view_variables = function(request){
//your code
$scope.isExpanded = !$scope.isExpanded;
};
and in html
<div class="title" ng-click="view_variables(request)">
<i class="glyphicon" ng-class="{'glyphicon-chevron-right':!isExpanded, 'glyphicon-chevron-left':isExpanded}"></i>
</div>
May be Better this way using ng-show directive:
<div class="title" ng-click="view_variables(request)">
<i class="glyphicon glyphicon-chevron-right" ng-show="!view_variables(request)"></i>
<i class="glyphicon glyphicon-chevron-left" ng-show="view_variables(request)"></i>
</div>
You could use ng-if directive like so:
<div class="title" ng-click="view_variables(request)">
<i class="glyphicon glyphicon-chevron-right" ng-if="!view_variables(request)"></i>
<i class="glyphicon glyphicon-chevron-left" ng-if="view_variables(request)"></i>
</div>
assuming view_variables(request) returns true or false... maybe could replace it for req.show_variables.
I want to check boolean data with angular ng-switch
this is my code. but it is not working
<div ng-switch={{Item.ItemDetails.IsNew}}>
<div ng-switch-when="true">
<p class="new fontsize9 fontWeightBold">NEW</p>
</div>
</div>
<div ng-switch={{Item.ItemDetails.IsFeatured}}>
<div ng-switch-when="true">
<div class="featured">
<p class="fontWeightBold fontsize8">featured</p>
</div>
</div>
</div>
values of {{Item.ItemDetails.IsNew}} and {{Item.ItemDetails.IsFeatured}} are true or false
Convert the boolean to a string:
<div ng-switch="Item.ItemDetails.IsNew.toString()">
<div ng-switch-when="true">
If you are just checking for true values, ng-if seems more appropriate and reduces the need for additional divs containing the code, reducing your sample too:
<div ng-if="Item.ItemDetails.IsNew">
<p class="new fontsize9 fontWeightBold">NEW</p>
</div>
<div class="featured" ng-if="Item.ItemDetails.IsFeatured">
<p class="fontWeightBold fontsize8">featured</p>
</div>
Full docs at: http://docs.angularjs.org/api/ng.directive:ngIf
This syntax works for me:
<div ng-switch="Item.ItemDetails.IsFeatured">
<div ng-switch-when="true">FEATURED ITEM HTML</div>
<div ng-switch-default>REGULAR ITEM HTML (not featured)</div>
</div>
You should remove the {{}} from the ng-switch:
Change this <div ng-switch={{Item.ItemDetails.IsNew}}>
to <div ng-switch=Item.ItemDetails.IsNew>
The attribute value of ng-switch are interpreted as literal string values to match against. (Meaning that cannot be expressions.) For example, ng-switch-when="someVal" will match against the string "someVal" not against the value of the expression $scope.someVal.
If you really have to use ng-switch, it can be forced to semi-use evaluative expressions by the workaround of the .toString() javascript method. Example, using the scope variables numeric 'lastSortIndex' and the boolean 'reverseSorted', plus the AngularJS HTML variable '$index':
<div ng-switch="((lastSortIndex === $index).toString()+(reverseSorted).toString())">
<div ng-switch-when="truetrue">
<span class="glyphicon glyphicon-chevron-up">{{ header }}</span>
</div>
<div ng-switch-when="truefalse">
<span class="glyphicon glyphicon-chevron-down">{{ header }}</span>
</div>
<div ng-switch-default>{{header}}</div>
</div>
Note the above example is concatenating the booleans together and then evaluating their string contents. Would be better to move this into a callable function that returns a string to be evaluated in the switch-case.
Though I would recommend if possible for you to keep the logic in the logic-controllers area of the code (the javascript files). You can use the ng-html-safe AngularJS directive in combination with their Sanitize feature to call a function in Javascript that switches and returns desired snippets of HTML code for you. Example:
index.html:
<html ng-app="myApp">
<head>
<script src="https://code.angularjs.org/1.3.13/angular-sanitize.js">
</head>
<body ng-controller="MainController">
<!-- add your other code, like a table code here -->
<div ng-bind-html="HeaderSortIcon(lastSortIndex, $index, reverseSorted, header)">
</div>
</body>
script.js:
var myApp = angular.module('myApp ', ['ngSanitize']);
$scope.HeaderSortIcon = function (lastSortIndex, $index, reverseSorted, header) {
if (lastSortIndex === $index) {
if( reverseSorted )
{
return '<div><span class="glyphicon glyphicon-chevron-up"></span>' + header + '</div>';
}
else{
return '<div><span class="glyphicon glyphicon-chevron-down"></span>' + header + '</div>';
}
}
else {
return header;
}
}
