Develop Reference

Is it possible to assign the hash(#) automatically in angular?

Is there any way where I can assign the hash(#) automatically to the elements inside an ngfor?
<div *ngFor="let note of notes; index as i">
<h3 #[note][i]>
{{ note }}
</h3>
</div>
The result I would expect would be something like this:
<div>
<h3 #note11>
note1
</h3>
</div>
<div>
<h3 #note122>
note12
</h3>
</div>
<div>
<h3 #note153>
note15
</h3>
</div>

You can use the index variable to automatically assign a unique id to each element in the ngFor loop. Here's an example:
<div *ngFor="let note of notes; index as i">
<h3 id="note{{i}}">
{{ note }}
</h3>
</div>
This will give each element an id of "note0", "note1", "note2", etc.
Regarding using #, it is not possible to use it in such a way. The # symbol is used to create a template reference variable, you can use it like <h3 #myNote>{{ note }} and you can access the element using myNote in your component.

Try this:
<div *ngFor="let note of notes; index as i">
<h3 #{{note}}{{i}}>
{{ note }}
</h3>
</div>
Note:
This would do your work but # is used to create template reference.

How to loop through unknow number of nested json object in Angular with ngFor?

I'm trying to display all the reply from this json :
https://www.reddit.com/r/AskReddit/comments/k8w43d/people_with_the_last_name_pepper_who_have.json
So, depending of the post im loading and the reply, my number of children will differ. How can I loop throught it until I reach the last reply with children (body[2].data.children) ?
Like this :
<div class="replies-box" *ngFor="let reply of comments.body[1].data.children">
<div class="reply-header">
<p class="reply-author"><b>From</b> : {{ reply.data.author }}</p>
<p class="reply-send"><b>Send</b> : {{ this.getDateReply(reply.data.created_utc) }}</p>
</div>
<div class="text-first-reply" [innerHTML]="this.getHtmlDecode(reply.data.body_html)">
</div>
</div>
I have only the first level of reply, is there a way to simply loop through them all ?
Thanks in advance.

I would use a recursion type of approach.
Develop a app-comment component and if comment has children, loop over the children and display the app-comment. That way it will loop over the comments until no more children
<div *ngIf='comment'>
<span *ngIf='comment.kind; else showComment'>Kind: {{ comment.kind }}</span>
<ng-template #showComment>
<span>{{ comment }}</span>
</ng-template>
<div>
<app-comment *ngFor='let child of comment.data?.children' [comment]='child'> </app-comment>
</div>
</div>
See this sample illustration

Simply use ngFor inside ngFor with help of ng-container (will not create extra dom elements)
<div class="replies-box">
<ng-container *ngFor="let commentBody of comments.body">
<ng-container *ngFor="let reply of commentBody.data.children">
<div class="reply-header">
<p class="reply-author">
<b>From</b> : {{ reply.data.author }}
</p>
<p class="reply-send">
<b>Send</b> : {{ this.getDateReply(reply.data.created_utc) }}
</p>
</div>
<div class="text-first-reply" [innerHTML]="this.getHtmlDecode(reply.data.body_html)">
</div>
</ng-container>
</ng-container>
</div>

how to add :key in v-for with multiple divs

I want to make v-for loop without any html element so I decided to use <template as parent. I don't know to assign :key for this loop. I can't assign it to template and to every div inside loop. Any ideas?
<template
v-for="{ id, text, option, percentage, value } in reports"
>
<div class="table-row__index">
{{ id }}
</div>
<div class="table-row__title">
<p>{{ text }} - <strong>{{ option }}</strong></p>
</div>
<div class="table-row__info">
{{ percentage }}%
</div>
<div class="table-row__info">
{{ value }}
</div>
</template>

As a good practice we should always have a parent element inside. But due to your constraints, it's okay to use for loop on template as given in official docs
https://v2.vuejs.org/v2/guide/list.html#v-for-on-a-lt-template-gt
In this case, any keys have to be added to child elements/components and this is what officially recommended.
See this example and please add keys to your div's inside template.
new Vue({
el: '#app'
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<template v-for="n in 5">
<span :key="'number' + n">{{ n }}</span>
<span :key="'dot' + n">. </span>
</template>
</div>

you just can't have the for loop in your template. The for loop directive is only allowed to be inside the first child component ( or root component) inside your template.
Here is an example of how you can render your loop:
<template>
<div class="cant-have-for-loop-this-is-the-root-component">
<div v-for="{ id, text, option, percentage, value } in reports" :key="{id}">
<div class="table-row__index">
{{ id }}
</div>
<div class="table-row__title">
<p> {{ text }} - <strong>{{ option }}</strong></p>
</div>
<div class="table-row__info">
{{ percentage }}%
</div>
<div class="table-row__info">
{{ value }}
</div>
</div>
</div>
</template>
This runs soomthly, and with no hesitations. And renders with no styling as this screenshots depicts:
Hope this answers what you want to achieve.

Add JavaScript logic in dynamically loaded template AngularJS

I'm dynamically loading templates which is working fine. Now my concern is I need to add a JavaScript logic to template
I need to use something like this in my template.
{{ var entries = 0; }}
{{ for(var r = 0; r < d; r++) }}
Suppose my template returns this HTML
<div ng-repeat="x in names" ><span>{{x.name}}</span>{{some logic here which is plain js. var a=[] if(a=b){}}}</div>
My question is how to achieve this.

<div ng-repeat="entry in entries track by $index">
{{entry}},{{$index}}
</div>

Use ng-repeat.
<div ng-repeat="entry in entries">
{{entry}}
</div>
If you need the index:
<div ng-repeat="entry in entries">
{{entry}},{{$index}}
</div>
Docs: https://docs.angularjs.org/api/ng/directive/ngRepeat

<div ng-init="entries[0,1,2,3,4]">//Use ng-int to initialize data
<div ng-repeat="data in entries">// use ng-repeat to loop over
{{data}}
</div>
</div>

Assign value to dynamically created scope variables

I'm trying to create a means to toggle dynamically created rows of information. I've tried using ng-init, and then passing it to a function, but I'm screwing up somewhere and I can't seem to wrap my head around how or if this is possible. The gap, I believe, is in getting the concatenated scope variable to be referenced elsewhere. I'm using Bootstrap 3 and AngularJS 1.5.
The HTML:
<div class="row" data-ng-repeat="equipment in task.equipment">
<div class="col-md-12">
<h4 class="green-text">
{{ equipment.equipId }}
<small class="green-text">
<i class="glyphicon"
data-ng-class="{'glyphicon-triangle-bottom': field{{ $index }}, 'glyphicon-triangle-right': !field{{ $index }}}"
data-ng-init="equipment['field' + $index] = true"
data-ng-click="toggleTaskEquip('field{{ $index }}')">
field{{ $index }}: I WANT THIS TO WORK</i>
</small>
</h4>
</div>
<div data-ng-show="field{{ $index }}">
...stuff here...
</div>
</div>
The JS:
$scope.toggleTaskEquip = function(toggleBool)
{
if (toggleBool === true)
$scope.isTaskEquipOpen = false;
else if (toggleBool === false)
$scope.isTaskEquipOpen = true;
};

If I understand the problem correctly, you want to be able to toggle the boolean created in the ng-init with a click.
I think you need this:
<div class="container-fluid">
<div ng-controller="MyCtrl">
<div class="row" data-ng-repeat="equipment in task.equipment">
<div class="col-md-12">
<h4 class="green-text">
{{equipment.equipId}}
<small class="green-text">
<i class="glyphicon"
data-ng-class="{'glyphicon-triangle-bottom': isVisible, 'glyphicon-triangle-right': !isVisible}"
data-ng-init="isVisible = true"
data-ng-click="isVisible = !isVisible">I WANT THIS TO WORK</i>
</small>
</h4>
</div>
<div data-ng-show="isVisible">
...stuff here...
</div>
</div>
</div>
</div>
You don't even need the function toggleTaskEquip on the $scope.
JSFiddle here.
ng-repeat creates a new scope for each template instance, so you can just create a separate isVisible for each equipment with isVisible = true in the ng-init.
