How do or can I create a filter for all of the members because right now I have about 50 members but the page only display 25 of them due to pagination. As the page only contains 25 member's data, I'm not sure if I can make a filter because the filtered search may be in the other 25 data not being fetch yet. Thanks in advance
Component
<input type="text" class="form-control border border-dark text-center" placeholder="Find someone ...">
<div class="row justify-content-center">
<div style="background-color:rgba(0,0,0, 0.1)" class= "card col-md-2 col-4 m-3 p-0" v-for="member in members" v-bind:key="member.id">
<a :href="`#${member.alias_name}`" #click="openModal(member)">
<img class="card-img-top" :src="getImgFile()">
<div class="card-body">
<p class="card-text text-white text-center">{{member.alias_name}}</p>
</div>
</a>
</div>
Methods
fetchMembers(page_url){
let vm=this;
page_url=page_url || '/api/members/fetchMembers'
fetch(page_url).then(res=>res.json()).then(res=>{
this.members = res.data;
vm.makePagination(res.meta,res.links);
})
.catch(err=>console.log(err));
},
makePagination(meta,links){
let pagination={
current_page:meta.current_page,
last_page:meta.last_page,
next_page_url:links.next,
prev_page_url:links.prev
}
this.pagination = pagination;
},
Controllers
public function fetchMembers()
{
$members = Member::orderBy("id","ASC")->paginate(25);
return MemberResource::collection($members);
}
To show more members in to your page just do this, edit this line:
public function fetchMembers()
{
$members = Member::orderBy("id","ASC")->paginate(100);//<----- 100 per page
return MemberResource::collection($members);
}
If the filter work's properly, you have to paginate throughout all filtered objects, my solution just explain how you can expand your paginated list from 25 items to 100.

I'm new to Angular and I can't really understand what is the problem I'm facing. I'm trying to pass object from an *ngFor to his component.
Here is a simple *ngFor that iterate an Array
<div class="card text-center" *ngFor="let alarm of alarms">
<div class="card-header">
....
</div>
<div class="card-body p-2">
<span class="text-secondary font-weight-bold">
Floor
<span>{{ alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].floor }}</span>
</span>
</div>
</div>
I want to avoid this long interpolation so I want pass the current let alarm to the component and assign three attributes to an object and display it,
customMethod(alarm) {
this.location.floor = alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].floor;
this.location.room = alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].room;
this.location.bed = alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].bed;
}
Here is what I expect:
<div class="card text-center" *ngFor="let alarm of alarms">
<div class="card-header">
....
</div>
<div class="card-body p-2">
<span class="text-secondary font-weight-bold">
Floor
<span>{{ location.floor }}</span>
</span>
</div>
</div>
And show the attribute's object location with string interpolation for each object alarm.
What is the best way to do this?
You want to avoid having any logic in your template (.html) file so I'll advise doing the logic in your component file.
You can prepare the alarms array before it's sent into the template.
#Component(..)
export class SomeComponent {
private _alarms;
#Input()
set alarms(alarms) {
this._alarms = alarms.map(alarm => customMethod(alarm))
}
get alarms() {
return this._alarms
}
}
function customMethod(alarm) {
return {
...alarm, // <<< remove this if you just want locations
locations: {
floor: alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].floor,
room: ....,
bed: ...
}
}
Then in your template
<div class="card text-center" *ngFor="let alarm of alarms">
<div class="card-header">
....
</div>
<div class="card-body p-2">
<span class="text-secondary font-weight-bold">
Floor
<span>{{ alarm.location.floor }}</span>
</span>
</div>
</div>
Create a helper method to get you the value you want to display, and then just call that from the template.
You can do anything to the object to get the value you want to display in here since it's just a funciton:
createMyString(alarm) {
return alarm.sensor.sentinel.monitorings_sentinels[0].monitoring.patient.location[0].floor;
}
Then in your template
{{createMyString(alarm)}}
I have a list of cards that i populate, when i click on each card i want to get and display the correct items displayed for that card.
The problem i am facing is that when i return an array its not binding the correct item to the specific card.
This is my HTML
<div repeat.for="Grouping of categoryItems">
<div class="row">
<div class="col s12 m3 l3">
<div class="card blue-grey darken-1">
<div class="card-content" style="padding:10px">
<span class="card-title white-text truncate">${Grouping.name}</span>
<a if.bind="Grouping.hideDetails" class="btn-floating halfway-fab waves-effect waves-light" click.delegate="Activate(list, Grouping)"><i class="material-icons">add</i></a>
</div>
</div>
</div>
</div>
<div repeat.for="categoryGroupingTypes of categoryItemTypes">
<div class="row" if.bind="!Grouping.hideDetails">
<div class="col" style="position:absolute;padding:5%">
<div class="rotate-text-90-negative">
<span class="blue-grey-text"><b>${categoryGroupingTypes.name}</b></span>
</div>
</div>
<div repeat.for="item of categoryItemsTypes.items" class="col s12 m3 l3 ">
<div class="card-content">
<span class="card-title white-text truncate">${items.Name} ${items.Quantity}</span>
</div>
</div>
</div>
</div>
</div>
</div>
my ts
async Activate(list: ListModel[], grouping: any) {
this.categoryItemsTypes = await this.getTypes(list);
let result = this.categoryItem.filter(x => x.name == grouping.name)
if (result) {
grouping.hideDetails = false;
}
}
so this.categoryItemsTypes has the following array
0: {name: "Clothes", items: Array(3)}
1: {name: "Shoes", items: Array(2)}
so when the page loads it loads the cards as follows
then when i click on "Clothes"
i only want it to load the array associated with clothes and if "shoes" is clicked then only load that array as follows
but what is currently happening with my above code is the following
this line is where i bind the items
repeat.for="item of categoryItemsTypes.items"
how can i bind the items to the correct ${Grouping.name} as shown in picture 2?
You are in the right direction, but not complete yet.
Array assignment are not observed by aurelia.
In general, when populating arrays with a new set of elements, this is a good way:
destarray.splice(0, destarray.length, ...sourcearray);
over
destarray = sourcearray;
because the former is observed by aurelia by default and the latter is not.
I am new to vue.js I am going to make a news app using a API.
In here I used v-for to iterate some codes. I think there is a problem in v-for. because it gives error. error has been included end of this question.
I used following codes to show search results
<template>
<div class="col-md-12">
<div>
<h2>Results</h2>
<div class="card mb-3" v-for="item in resultList">
<img class="card-img-top" src="" alt="Card image cap" height="100" width="200">
<div class="card-body">
<h5 class="card-title">{{ item.name }}</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<div class="button">
<button type="button" class="btn btn-primary">Show more</button>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default{
props: ['resultList']
}
</script>
following codes used to get the api data(search api data)
<template>
<div class="container1">
<div class="form-group row">
<label for="exampleInputPassword1">Search Music</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="exampleInputPassword1" placeholder="Type here"
#input="keypressed">
</div>
</div>
</div>
</template>
<script>
import axios from 'axios'
export default{
data () {
return {
newset: []
}
},
methods: {
keypressed () {
var key = event.target.value
axios.get('http://newsapi.org/v2/everything?q=' + key +
'&sortBy=publishedAt&apiKey=b5ac77726d0a4460bd82b57210b2efb7')
.then(response => {
this.newset = response.data.articles
})
.catch(e => {
this.error.push(e)
})
this.$emit('newDataset', this.newset)
}
}
}
</script>
but it gives an error. error is
https://google.com/#q=vue%2Frequire-v-for-key Elements in iteration expect to have 'v-
bind:key'
directives
src\components\ResultArea.vue:5:5
<div class="card mb-3" v-for="item in resultList">
^
You need to add :key binding:
<div class="card mb-3" v-for="(item, index) in resultList" :key="index">
key value should be unique for every item. If your list items has any id it is good idea to use this id here:
<div class="card mb-3" v-for="item in resultList" :key="item.id">
To give Vue a hint so that it can track each node’s identity, and thus reuse and reorder existing elements, you need to provide a unique key attribute for each item. check the link for better understanding

I want to show data using ng-click
First i have listing for of all the companies, this works fine. it displays all the companies.:
<div class="col-xs-3" ng-repeat="item in companyData">
<a ng-click="getPackageInfo({id:item.iCompanyID})" class="block panel padder-v bg-primary item">
<span class="text-white block">{{item.vCompanyName}}</span>
</a>
</div>
Now on click of company name, i have to display other info like packges of that company, for that i have done this under above div:
<div ng-repeat="item in pData" class="col-xs-3">
<a ng-click="" class="block panel padder-v bg-primary item">
<span class="text-white block">{{item.vPackageName}}</span>
</a>
</div>
In controller.js i did this, getPackageInDetail will return package listing according to company id:
function getPackageInfo(id) {
SubscriptionoptioncompanylistFactory.getPackageInDetail(id).
success(function(data) {
$scope.pData = data;
}).
error(function(data,status,header,config) {
$scope.pData = 0;
});
};
How can i append the data according to company clicked?
Array.prototype.push.apply() can be used for merging two arrays.
Merge the second array into the first one
//Define an empty array
$scope.pData = [];
$scope.getPackageInfo = function(id) {
SubscriptionoptioncompanylistFactory.getPackageInDetail(id).
success(function(data) {
Array.prototype.push.apply($scope.pData, data); //Merge the array
});
};
Additionally, I think you need to pass ID properly
<a ng-click="getPackageInfo(item.iCompanyID)">
I have made a small app using AngularJS 1.4, that outputs JSON data from a remote source.
Here is the JSON data in question.
Here is my view - the link to ngInfiniteScroll comes in at the top of the container:
<body ng-app="cn" ng-controller="MainCtrl as main">
<div id="header" class="container-fluid">
<p>Camper News</p>
</div>
<div class="container">
<div infinite-scroll="feed.loadMore()" infinite-scroll-distance="3">
<div ng-repeat="newsItem in myData" class="news-row col-sm-12 col-xs-12">
<div class="col-sm-2 col-xs-12">
<div id="img-container">
<img ng-src={{newsItem.author.picture}} id="user-avatar" />
</div>
</div>
<div class="news-text col-sm-10 col-xs-12">
<a href={{newsItem.link}}><em>{{newsItem.headline}}</em></a>
</div>
<div class="col-sm-10 col-xs-12" id="link-description">
{{newsItem.metaDescription}}
</div>
<div class="col-sm-12 col-xs-12" id="bottom-text">
<div class="col-sm-4 col-xs-12" id="author">
<a href='http://www.freecodecamp.com/{{newsItem.author.username}}'>{{newsItem.author.username}}</a>
</div>
<div class="col-sm-4 col-xs-12" id="likes">
<i class="fa fa-thumbs-o-up"></i> {{newsItem.upVotes.length}}
</div>
<div class="col-sm-4 col-xs-12" id="timestamp">
<span am-time-ago={{newsItem.timePosted}} | amFromUnix></span>
</div>
</div>
</div>
</div>
</div>
</body>
I am attempting to stagger the loading and outputting of the data using ngInfiniteScroll. I'm just not sure how it would work:
app.controller('MainCtrl', function($scope, Feed) {
$scope.feed = new Feed();
});
app.factory('Feed', function($http) {
var Feed = function() {
this.items = [];
this.after = '';
};
Feed.prototype.loadMore = function() {
var url = "http://www.freecodecamp.com/news/hot";
$http.get(url).success(function(data) {
var items = data;
// Insert code to append to the view, as the user scrolls
}.bind(this));
};
return Feed;
});
Here is a link to the program on Codepen. The code that relates to ngInfiniteScroll (controller and factory) is currently commented out in favour of a working version, but this of course loads all links at once.
What do I need to insert in my factory in order to make the JSON load gradually?
From what I can tell, by looking at FreeCodeCamps' story routes, there is no way to query for specific ranges of the "hot news" stories.
It looks to just return json with a fixed 100 story limit.
function hotJSON(req, res, next) {
var query = {
order: 'timePosted DESC',
limit: 1000
};
findStory(query).subscribe(
function(stories) {
var sliceVal = stories.length >= 100 ? 100 : stories.length;
var data = stories.sort(sortByRank).slice(0, sliceVal);
res.json(data);
},
next
);
}
You can use infinite scroll for the stories it does return to display the local data you retrieve from the request in chunks as you scroll.
