I'm creating an app using fake JSONplaceholder API. I'm displaying a list of posts and I want the ng-repeated post titles to link to the post view.
Here's the HTML:
<body layout="column" ng-app="myApp" ng-cloak ng-controller="controller">
<h1>{{apptitle}}</h1>
<script type="text/ng-template" id="allposts.htm">
<a href="#addpost">
<button type="button" class="btn btn-primary addbtn" ng-model="singleModel" uib-btn-checkbox btn-checkbox-true="1" btn-checkbox-false="0">
Add a post
</button>
</a>
View
<select ng-model="viewby" ng-change="setItemsPerPage(viewby)">
<option>9</option>
<option>18</option>
<option>36</option>
<option>100</option>
</select>posts
<div class="row" ng-repeat="collatedPostList in collatedPosts">
<div class="onepost col-xs-4 box" ng-repeat="post in collatedPostList">
<div class="inner">
<a href="#/posts/{{post.indexOf(post)}}">{{post.title}}</a>
<p>{{post.body | limitTo: 60}}{{post.body.length < 20 ? '' : '...'}}</p>
</div>
</div>
</div>
<div class="text-center">
<ul uib-pagination total-items="totalItems" ng-model="currentPage" class="pagination-sm"
items-per-page="itemsPerPage" ng-change="pageChanged(currentPage)"></ul>
</div>
</script>
<script type="text/ng-template" id="posts.htm">
</script>
<script type="text/ng-template" id="addpost.htm">
<form ng-submit="addPost()" class="adding">
<input id="titleadd" type="text" name="title" ng-model="newPost.title" placeholder="Add title">
<br>
<input id="textadd" type="text" name="body" ng-model="newPost.body" placeholder="Add some text">
<br>
<button type="submit" ng-click="addAlert(msg,'success')" class="btn btn-primary" id="submit" value="Submit">
Post it
</button>
<a href="#allposts">
<button type="button" class="btn btn-primary" >
Go back to post list
</button></a>
<br>
<uib-alert
ng-repeat="alert in alerts"
type="{{alert.type}}"
dismiss-on-timeout="5000"
close="alerts.splice($index, 1);">{{alert.msg}}
</uib-alert> </form>
</script>
<div ng-view></div>
<script src="app.js"></script>
</body>
and JS:
Array.prototype.collate = function(collateSize) {
var collatedList = [];
if (collateSize <= 0) {
return [];
}
angular.forEach(this, function(item, index) {
if (index % collateSize === 0) {
collatedList[Math.floor(index / collateSize)] = [item];
} else {
collatedList[Math.floor(index / collateSize)].push(item);
}
});
return collatedList;
};
var myApp = angular.module('myApp', ['ngRoute', 'ui.bootstrap']);
myApp.config(function($routeProvider) {
$routeProvider.when('/', {
templateUrl: 'allposts.htm',
controller: 'PostsController'
}).when('/posts', {
templateUrl: 'posts.htm',
controller: 'PostController'
}).when('/addpost', {
templateUrl: 'addpost.htm',
controller: 'AddController'
}).otherwise({
redirectTo: '/'
});
});
myApp.controller('PostsController', function($scope) {});
myApp.controller('PostController', function($scope) {});
myApp.controller('AddController', function($scope) {});
myApp.controller('controller', function($scope, $http) {
$scope.apptitle = "My app";
$http({
method: 'GET',
url: "http://jsonplaceholder.typicode.com/posts"
}).then(function(response) {
$scope.posts = response.data;
$scope.viewby = 9;
$scope.totalItems = $scope.posts.length;
$scope.currentPage = 1;
$scope.itemsPerPage = $scope.viewby;
$scope.maxSize = 5;
$scope.collatedPosts = getCollatedPosts($scope.posts);
$scope.newPost = {};
function getCollatedPosts(posts) {
if (!posts) {
return [];
}
var paginatedPosts = posts.slice((($scope.currentPage - 1) * $scope.itemsPerPage), (($scope.currentPage) * $scope.itemsPerPage));
return paginatedPosts.collate(3);
}
$scope.setPage = function(pageNo) {
$scope.currentPage = pageNo;
};
$scope.setItemsPerPage = function(num) {
$scope.itemsPerPage = num;
$scope.currentPage = 1; //reset to first page
$scope.collatedPosts = getCollatedPosts($scope.posts);
};
$scope.pageChanged = function(currentPage) {
$scope.currentPage = currentPage;
$scope.collatedPosts = getCollatedPosts($scope.posts);
};
$scope.addPost = function(){
$http.post("http://jsonplaceholder.typicode.com/posts",{
title: $scope.newPost.title,
body: $scope.newPost.body,
usrId: 1
})
.success(function(data, status, headers, config){
console.log(data);
$scope.posts.push($scope.newPost);
$scope.newPost = {};
})
.error(function(error, status, headers, config){
console.log(error);
});
};});
$scope.alerts = [];
$scope.msg = "Well done! Your post was added";
$scope.addAlert = function(msg, type) {
$scope.alerts.push({
msg: msg,
type: type
});
};
});
My code is not working. There is 100 ng-repeated posts and I want each post title to link to the post view. Current code links every title to #/posts. I also tried <a href="#/posts/{{post.id}}">{{post.title}}</a>, but with no success.
What is the correct way to do this?
