I have a list of user-details stored in userList.
I am rendering these list of users in a div tag as follows:
<ul>
<li class="extra-users" ng-repeat="member in view.userList">
<input class="add-friends-check add-friends{{$index}}" type="checkbox" ng-checked="member.ischeck" />
</li>
</ul>
Now Problem occurs If same userList is used to render users in multiple div tags.
i.e.
<div class="1">
<ul>
<li class="extra-users" ng-repeat="member in view.userList">
<input class="add-friends-check add-friends{{$index}}" type="checkbox" ng-checked="member.ischeck" />
</li>
</ul>
</div>
<div class="2">
<ul>
<li class="extra-users" ng-repeat="member in view.userList">
<input class="add-friends-check add-friends{{$index}}" type="checkbox" ng-checked="member.ischeck" />
</li>
</ul>
</div>
Now If two users are selected/checked in div1, it gets reflected in div2 as well since view.userList is getting updated.
One way to solve it is clone userList and assign cloned userList` to div1 and userList`` to div2.
But that is causing me performance issues If I load more than 15 or 20 divs.
Is there any way we can avoid selecting a user in one div not reflecting in another?
Thanks in Advance

I'm very new to tizen web. I have an app that gets data from mqtt broker and controls wi-fi lamp. I have list page with 3 pages, that allow to control brightness, speed, scale. I get data from mqtt every time when the lamp changes its state and I want to update the level in each page.

I tried to get element from brightness.html like this document.querySelector("input[data-slider-type='bri']") to set value, but it returns null. When I try to get access to this element of index.html document.getElementById("t_swtch") and it works fine.
I need to get access to this element from my index.html page.
Not sure it's the case, but maybe there's a typo in your query. I've tried the exact same query you use, but with the closing ) - document.querySelector("input[data-slider-type='bri']") and it returned the corresponding element
I have a demo application here and in the upper left corners of the "tweets" there are dots and I have no idea where they come from. The code is written in Ember and the template looks like this

<h2>Tweets</h2>
<button {{action 'changeAllTweets'}}>Change All Tweets</button>
<button {{action 'changeOneTweet'}}>Change One Tweet</button>

P.S. The SHOW LIST button must be pressed for the list to show
It's because you're using list items, i.e. <li> tags. They're shown with bullet points by default.
First of all, you should only use <li> tags inside an ordered or unordered list (<ol> / <ul>). You should consider if list items are appropriate here. Maybe <div>s are more suitable?
If you want to use list items you should wrap them in a <ul> list and then get rid of the bullet points by applying the styling: list-style-type: none.
Changing the display style of the list item will also get rid of the bullet point.
These are the list item markers. Add list-style:none; to the ul, and they will disappear.
Edit: I see that you are also missing the ul itself. The wrapping ul does not exist. These are just list items. Add the opening ul before the each statement and closing after it. And in case the list style none rule.
I'm on mobile and can't edit the fiddle.
There is HTML structural error.
Wrap the <li class="media"> with an <ul> tag. I can assume you are using Bootstrap. If yes then wrap the <li> tag with <ul class="list-group"> and add list-group-item class to the <li> tag like this: <li class="media list-group-item">
I want to create dropdown with country->region->city selection.
The first ul opens from click on that span and the others set to show on hover (code at the bottom).
<input type="text" id="srch-area" alt="" class="c-textfield suggestionsInput " name="locationStr" maxlength="" size="" tabindex="3" title="" value="Deutschland" defaultvalue="" highlight="y" strict="y" autocomplete="off">
<span class="c-icon-arrow-green-down-left c-icon" id="loc-slctbx"></span>
<ul class="dropdown-location-ul" id="dropdown-country" style="display:none;">
<li class="dropdown-location-li">
<strong>Deutschland</strong>
<ul class="dropdown-location-ul" style="display:none;">
<li class="dropdown-location-li">
<strong>Brandenburg</strong>
<ul class="dropdown-location-ul" style="display:none;">
<li class="dropdown-location-li">
<strong>Oranienburg</strong>
</li>
<li class="dropdown-location-li">
<strong>Schwedt</strong>
</li>
...
</ul>
</li>
<li class="dropdown-location-li">
<strong>Berlin</strong>
</li>
...
</ul>
</li>
<li class="dropdown-location-li">
<strong>France</strong>
</li>
...
</ul>
$('.dropdown-location-li').hover(function(){
$(this).children('ul').css('left', $(this).parent('ul').width()+'px');
$(this).children('ul').show();
}, function(){
$(this).children('ul').hide();
});
This works just fine and now i need to make it on click to change value of near input to the name of location inside strong tag. I tried the code below but it appears that $(this) selecting the element and all his parents, but i need to get location from only the one i clicked. Please tell me how to do that correctly? Maybe i have completely wrong approach to do this and need to make all with id's and stuff, but i just wanted to minimise the amout of repeating js.
$('.dropdown-location-li').click(function(){
$('#srch-area').val($(this).children('strong').text());
$('#dropdown-country').hide();
});
This is how it shows in console. AS you can see when i click on Oranienburg it selects Brandenburg and Deutschland as well which are the parents of the element i clicked.

You have nested .dropdown-location-li elements, so the click keeps propagating up to the other LI elements, firing the event handler again etc.
You should stop the propagation the first time
$('.dropdown-location-li').click(function(e){
e.stopPropagation();
$('#srch-area').val($(this).children('strong').text());
$('#dropdown-country').hide();
});
try to use JQuery Find
$(this).find('strong').text()
I've searched for a while and did find a lot about multiple iterations. The problem is that i don't see a plain solution for my problem.
I have a list of checkbox that is filled dinamically with ng-repeat. Due to layout purposes i need to create a new div inline-block whenever i reach 3 checkboxes. Like that:
CheckBoxList = {1,2,3,4,5}
<div class="form-group-content">
<div class="form-col-secondary">
<ul class="list-checkboxes">
<li>
<input type="checkbox"/>1
</li>
<li>
<input type="checkbox"/>2
</li>
<li>
<input type="checkbox"/>3
</li>
</ul>
</div>
<div class="form-col-secondary">
<ul class="list-checkboxes">
<li>
<input type="checkbox"/>4
</li>
<li>
<input type="checkbox"/>5
</li>
</ul>
</div>
</div>
I tried using a iterator and two ng-repeat but didn't work like i wanted to.
If somebody already had this struggle and could help i would appreciate it.
To achieve this you will have to make 2 updates.
2 ng-repeat
Change structure
HTML Code
<div class="form-group-content">
<div class="form-col-secondary" ng-repeat="block in blocks">
<ul class="list-checkboxes">
<li ng-repeat="checkbox in block">
<input type="checkbox{{$index + 1}}"/>
</li>
</ul>
</div>
</div>
JS Code
$scope.blocks = [
['1','2','3'],
['4','5']
];
Here is a plunker for you - http://plnkr.co/edit/BWcFI5d02yPkAYDiQxvO?p=preview
If you split your CheckBoxList in parts of 3, you can use your ng-repeat on each div.
So change checkboxlist to something like:
divs = [[1,2,3],[4,5,6]];
then your html:
<div class="form-col-secondary" ng-repeat="div in divs">
<ul class="list-checkboxes">
<li ng-repeat="checkbox in div">
<input type="checkbox" ng-attr-id="{{checkbox}}">
</li>
</ul>
</div>
This might nog exactly match what you want as result, but it reflects the principle on which you should be able to create your own working version :-)
Edit
Worth noting: As far as I am aware, you can't have <input type="checkbox1" />, I think you mean <input type="checkbox" id="1" name="checkbox1" /> instead.
You'll have to track by $index in your ng-repeat and either ng-if or ng-show and $index < 3 for your first set and $index > 2 for the second set.
I would like to do this really basic example :
<div ng-controller="ctrl">
<li ng-repeat="config in configs">
<span >Config : {{config}}</span>
<li ng-repeat="version in versions">
{{config}}
</li>
</li>
</div>
So basically, I got 2 imbricated ng-repeat loop, and I would like to access a value of the first loop from the second one.
I thought it was really basic, but no way to make it work. My result of that is 1 liwith the config printed, and 3 empty sub lis
I already tried a lot of combination list {{$parent.index}}, {{$parent.config}} etc ...
I'm pretty sure this has to do with the structure of your HTML.
Here is a working plunker.
Since you are omitting the <ul> tags that are required for lists. The nested <li> is causing a display issue.
I have simple wrapped the <li> with <ul> and it seems to work fine:
<div ng-controller="ctrl">
<ul>
<li ng-repeat="config in configs">
<span >Config : {{ config }}</span>
<ul>
<li ng-repeat="version in versions">
VersionConfig: {{ config }}
</li>
</ul>
</li>
</ul>
</div>
