Adjust your template:
<div ng-repeat="data in datab track by $index">
<ul class="list">
<li class="item" ng-click="singlegolf(data.href)" ng-model="la">{{data.href}}</li>
</ul>
</div>

I have a piece of code which is a basic example of how to use angular-ui-tree:
<div ui-tree>
<ol ui-tree-nodes="" ng-model="list">
<li ng-repeat="item in list" ui-tree-node>
<div ui-tree-handle>
{{item.title}}
</div>
<ol ui-tree-nodes="" ng-model="item.items">
<li ng-repeat="subItem in item.items" ui-tree-node>
<div ui-tree-handle>
{{subItem.title}}
</div>
</li>
</ol>
</li>
</ol>
</div>
Now if I have an {{item}}, is there a way to get the item's iteration on the loop? Like for example I want to get a condition that if this item's current loop iteration is an odd number or an even number for instance, I could change the style of the certain node of the tree like say I have an alternate blue and red items based on its iteration if it's odd or even.
You can use $index in your ng-repeat loop it will give you the interation number-
ng-class="{ even : $index%2 == 0, odd : $index%2 != 0 }"
CSS
.even {
color: blue;
}
.odd {
color: red;
}
Final code
<div ui-tree>
<ol ui-tree-nodes="" ng-model="list">
<li ng-repeat="item in list" ui-tree-node>
<div ui-tree-handle>
{{item.title}}
</div>
<ol ui-tree-nodes="" ng-model="item.items">
<li ng-repeat="subItem in item.items" ui-tree-node>
<div ui-tree-handle ng-class="{ even : $index%2 == 0, odd : $index%2 != 0 }">
{{subItem.title}}
</div>
</li>
</ol>
</li>
</ol>
</div>
I have an application that polls the server via ajax and adds the json to an ng-repeat.
I'd like to know how I can highlight the latest entry to the list?
<div id="activity-listing" ng-controller="activityListing">
<ul>
<li ng-repeat="task in activity track by task.id | orderBy:'task.id':true" class="activity-item">
<div class="activity-person">{{ task.name }}</div>
<div class="activity-type">{{ task.activity }}</div>
<div class="activity-time" am-time-ago="task.time"></div>
<div class="activity-location">{{ task.location }}</div>
</li>
</ul>
</div>
You can use $last and then apply a CSS animation on it.
https://docs.angularjs.org/api/ng/directive/ngRepeat
ng-class="{lastItem: $last}"
<div id="activity-listing" ng-controller="activityListing">
<ul>
<li ng-repeat="task in activity track by task.id | orderBy:'task.id':true" class="activity-item" ng-class="{lastItem: $last}">
<div class="activity-person">{{ task.name }}</div>
<div class="activity-type">{{ task.activity }}</div>
<div class="activity-time" am-time-ago="task.time"></div>
<div class="activity-location">{{ task.location }}</div>
</li>
</ul>
</div>
I have the following code in the html. In the ng-click="inbox.showView('in: {{category|lowercase}}')" the double braces is not working because it is being considered as a string and not as a variable.
How do I ensure I have the category value in the ng-click event?
<li ng-repeat="category in inbox.categories track by $index">
<a href="#">
<div class="left-row" ng-click="inbox.showView('in: {{category|lowercase}}')" target="_self">
<div class="leftcolumn1"><span class="glyphicon glyphicon-user"></span></div>
<div class="leftcolumn2">{{category}}</div>
<div class="leftcolumn3 email-time" ng-bind="inbox.messageCounts.socialCount"></div>
</div>
</a>
</li>
In the controller:
$scope.inbox = {
categories: ['Name', 'Test'],
showView : function(variable) {
**console.log(variable);**
}
};
In the HTML given the parameter for showView function is object,, hence pass like the below inbox.showView({'in': (category | lowercase) })
<li ng-repeat="category in inbox.categories track by $index">
<a href="#">
<div class="left-row" ng-click="inbox.showView({'in': (category | lowercase) })" target="_self">
<div class="leftcolumn1"><span class="glyphicon glyphicon-user"></span></div>
<div class="leftcolumn2">{{category}}</div>
<div class="leftcolumn3 email-time" ng-bind="inbox.messageCounts.socialCount"></div>
</div>
</a>
</li>
I have a JSON object which I am repeating with ng-repeat, the keys are strings, and the values are an array. I am listing each of the values as a checkbox. I would like to create a second object which contains a list of only the checkboxes that are checked. I want to preserve the structure of the object with keys and values.
I'm unsure how to bind this to a model properly so that the structure is preserved.

This is my HTML
<h3 >Dynamic data binding in AngularJS</h3>
<div ng-app ng-controller="Controller" class="container">
<h4>Inputs</h4>
<ul ng-repeat="(parent, values) in inputs">
<span>{{parent}} : </span>
<li ng-repeat="value in values"><label>{{value}}
<input type="checkbox" ng-model="output[parent]" ng-checked="output[parent]" value="value" >
</input></label>
</li>
</ul>
<h4>Outputs</h4>
<ul ng-repeat="(key,value) in inputs">
<li>
{{key}} : {{output[key]}}
</li>
</ul>
</div>
and my JS
function Controller($scope) {
$scope.output = {};
$scope.inputs = {'category': ['one','two','three'], 'color':['blue','green']};
}
Is there some simple way to do this? I have the feeling that I'm missing something minor and this will all work nicely.
My examples have your angular logic in the recommended syntax (non-global). There were also several issues with your markup that I have corrected.
In this example, ng-model="x" is a placeholder that I don't use, but ng-model must be present or an error is thrown. I am using ng-change to handle the link between the checkboxes and $scope.outputs.

Markup:
<div ng-app="myApp" ng-controller="myCtrl">
<h3 >Dynamic data binding AngularJS</h3>
<h4>Inputs</h4>
<ul>
<li ng-repeat="(typeKey, typeVal) in inputs">
<span>{{typeKey}} : </span>
<ul>
<li ng-repeat="value in typeVal">
<label>{{value}}
<input
type="checkbox"
ng-model="x"
ng-change="setOutput(typeKey, $index, value)"
>
</label>
</li>
</ul>
</li>
</ul>
<h4>Outputs</h4>
<ul ng-repeat="(key,value) in inputs">
<li>{{key}} : {{outputs[key]}}</li>
</ul>
</div>
JavaScript:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.outputs = {};
$scope.inputs = {
'category': ['one','two','three'],
'color':['blue','green']
};
$scope.setOutput = function(typeKey, $index, value) {
$scope.outputs[typeKey] = $scope.outputs[typeKey] || [];
$scope.outputs[typeKey][$index] = value;
};
});
Another Solution
Live demo here (click).
First, I used ng-init to dynamically add the first-level properties from inputs to outputs. Then you just needed to set your ng-model and ng-checked properties to the correct location in outputs.
Markup:
<div ng-app="myApp" ng-controller="myCtrl">
<h3 >Dynamic data binding AngularJS</h3>
<h4>Inputs</h4>
<ul>
<li
ng-repeat="(typeKey, typeVal) in inputs"
ng-init="outputs[typeKey] = outputs[typeKey] || {}">
<span>{{typeKey}} : </span>
<ul>
<li ng-repeat="value in typeVal">
<label>{{value}}
<input
type="checkbox"
ng-model="outputs[typeKey][value]"
ng-checked="outputs[typeKey][value]"
value="outputs[typeKey][value]"
>
</label>
</li>
</ul>
</li>
</ul>
<h4>Outputs</h4>
<ul ng-repeat="(key,value) in inputs">
<li>{{key}} : {{outputs[key]}}</li>
</ul>
</div>
JavaScript:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.outputs = {};
$scope.inputs = {
'category': ['one','two','three'],
'color':['blue','green']
};
});
You need to bind to the value for the parent, as checkboxes don't work like that. Here's an example:
<h3 >Dynamic data binding in AngularJS</h3>
<div ng-app ng-controller="Controller" class="container">
<h4>Inputs</h4>
<ul ng-repeat="(parent, values) in inputs">
<span>{{parent}} : </span>
<li ng-repeat="value in values"><label>{{value}}
<input type="checkbox" ng-model="output[parent][value]" ng+checked="output[parent][value]" value="value" >
</input></label>
</li>
</ul>
<h4>Outputs</h4>
<ul ng-repeat="(key,value) in inputs">
<li>
{{key}} : {{output[key]}}
</li>
</ul>
</div>
And in the controller create the keys beforehand
function Controller($scope) {
$scope.output = { 'category': {}, color: {} };
$scope.inputs = {'category': ['one','two','three'], 'color':['blue','green']};
}

I cannot seem to get out the values I need from a nested ng-repeat in AngularJS.
I have the following data sent from the server:
[{"Your Turn":[{"gameToken":"sSFK0OHhYa8M4F6Z5Z1uNFnawQNVkZXj1GZyTEeSv2h8gntr9UrEU5FQsR9r8YWMWvjA6tePINbOm2Fc5u8U659QaRK0dju0","friendId":"522eec17e4b088a0a939cfdb","friendName":"Michelle","status":"You are waiting for Michelle Miguelamimio Agoramarketomercado to accept your challenge"}]},{"Their Turn":[{"gameToken":"sSFK0OHhYa8M4F6Z5Z1uNFnawQNVkZXj1GZyTEeSv2h8gntr9UrEU5FQsR9r8YWMWvjA6tePINbOm2Fc5u8U659QaRK0dju0","friendId":"522eec17e4b088a0a939cfdb","friendName":"Michelle Miguelamimio Agoramarketomercado","status":"You are waiting for Michelle to accept your challenge"}]}]
And the following template for the HTML:
<div ng-repeat="turn in data">
<p>{{turn}}</p>
<ul class="list-bare list-inline tab-group">
<li ng-repeat="(key, value) in turn" class="tab tab-active txt-upper {{key | lowercase}}">{{key}}</li>
</ul>
<ul class="list-bare list-users clearfix">
<li class="clearfix" ng-repeat="game in turn">
<div class="avatar-container">
<img class="avatar" ng-src="{{baseUrl}}/shobo/user/avatar/{{game.friendId}}" alt="{{game.friendName}}" />
</div>
<div class="list-users-info">
<h3 class="text-cap">{{game.friendName}}</h3>
<p>{{game.status}}</p>
</div>
<div class="list-users-status txt-center" ng-click="acceptChallenge(game.gameToken,game.friendId)">
<div><i class="icon-chevron-right"></i></div>
</div>
</li>
</ul>
</div>
I am not seeing any of the 'game' values being output from the second ng-repeat and am not sure what i am doing wrong?
<li class="clearfix" ng-repeat="game in turn">
should be
<li class="clearfix" ng-repeat="game in value">
need to make some changes in data and html to make require html
$scope.data=[{
"Title":"Your Turn",
