how to combine such usage of ng-class?
I need to use together function hich returns class, and expression, which evaluates another class
data-ng-class="{active: field.Selected} getDisplayClass(field.Size)"
You can do it as follows
<div data-ng-class="{active: field.Selected}" class="{{ getDisplayClass(field.Size) }}"> ... </div>

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.
What i'm trying to do is similiar to an accordion.
Simple put
i have an ng-repeat with an <a> tag that once clicked show another div called "Printpanel" nested inside it within ng-show.
If the user cick to another <a> tag, i want to hide all other div showed before, and open only to that one related.
I am using $index to trigger the specific div.
Here what i have done:
<div ng-repeat="product in $ctrl.Products">
<a href="#" ng-click="showDetails = $index;>CONFIGURE</a>
<div class="Printpanel ng-hide" ng-show="showDetails == $index" ng-hide="showDetails != $index">
</div>
it seems that ng-hide is not recognized... Anybody have an idea?
You don't need to use ngShow + ngHide: one is enough.
<div class="Printpanel ng-hide" ng-show="showDetails == $index">
You can use ng-if also:
<div class="Printpanel" ng-if="showDetails == $index">
EDIT:
due to scope inheritance problem, you are not able to set showDetails variable. use $parent for that.
working example:
<div ng-repeat="product in $ctrl.Products">
CONFIGURE
<div class="Printpanel" ng-if="$parent.showDetails == $index"> </div>
</div>
seems you have missed closing double quotes here ng-click="showDetails = $index;
Also either of one you need to use ng-show/ng-hide/ng-if = expression
I had this problem when calling a function from ng-click using $scope.var as parameter.
For instance:
Not Working:
<div ng-repeat="value in values track by $index">
<a ng-click="function({{ value }})">{{ value }}</a>
</div>
Working:
<div ng-repeat="value in values track by $index">
<a ng-click="function(value)">{{ value }}</a>
</div>
Why we can't use {{ }} if the variable is from $scope, declared on an Angular controller? Is there others situations when I will not use it?
We can not use expressions in directives like ng-click.
Expression can access variables and functions from the scope.
while using it in function, there is no need to write expression
First thing function is in built keyword.You can not use it.
suppose in controller you defined function like this.
$scope.callMe = function(){
}
then define the html :
<div ng-repeat="value in values track by $index">
<a ng-click="callMe(value)">{{ value }}</a>
</div>
I have an item in my array that is true or false.
I use this to say
<div ng-show="{{ item.isDirectory }}">
I also want to use the same rule to apply a class to that div if item.isDirectory == true
First, it's incorrect:
<div ng-show="{{ item.isDirectory }}">
ngShow waits an expression, it works just as below:
<div ng-show="item.isDirectory">
Also, preferably use ngIf directive as a good practice.
To apply a class in your div based on a condition, you should use ngClass directive:
<div ng-class="{ 'yourTrueclass': item.isDirectory, 'yourFalseClass': !item.isDirectory }"></div>
Take a look on this tutorial.
I have a lot of data within ng-repeat. It looks like table with many rows and columns. I want to put ng-click directive on some of cell of table.
Can i put some condition before ng-click directive? If this condition is true - I want to put the directive, otherwise - not to put.
I think you should just put the directive in there and pass it a condition as a parameter which returns boolean. In the directive compile function check if your parameter is right and decide from there what you load.
Maybe this is what you were looking for?
<ul class="menuItems">
<li ng-repeat="item in menuItems">
<div ng-if="item.type == 'link' ">
{{item.name}}
</div>
<div ng-if="item.type == 'function' ">
<span ng-click="function(item.command)" title="item.description">{{item.name}}</span>
</div>
</li>
</ul>
