How to use v-model inside v-for loop in Vue js

this is my first question here, I'm really desperate and I hope you can help me.
I'm trying to build a post/comment/reply system like Facebook by using vuejs, I'm using v-for to loop all posts/comments/replies after I use Axios to fetch data in my database (using laravel API), the problem here that I have input with v-model attached to a form inside my v-for loops when I type in my of my input it appears in all other inputs that has been looped here is an image for better understanding -> duplicate input,
<div class="panel panel-white post panel-shadow" v-for="(post) in posts" >
<div class="post-heading">
<div class="pull-left image">
<img src="https://bootdey.com/img/Content/user_1.jpg" class="img-circle avatar" alt="user profile image">

the easy way is put every post, comment and reply in separate components remember that's components for, to have separate states(or data) that you can easily manipulate it this way you write not only hard too extends but also its unreadable.
but the only way too bind a state in loop the way i said you can try with computed
v-model="replies[index].reply"
to:
v-model="replyComputed(index)"

Your problem is that replies.reply is the same for every looped comment. You should bind the reply to the specific comment you currently are iterating over e.g. v-model="comment.reply".

Google tag manager get closest a text

i want use custom js variable to get card-title a shop-item-title-link's text for the event label = "product x".
Clicking the click class fa-cart-plus to get the label product x;
Click the image to get the label product x
I've tried this js below, but it gets [object] [object] as the result.
function() {
var el = {{Click Element}};
return $(el).closest('card-title').text('a.shop-item-title-link');
}
HTML
<div class="card card-product">
<div class="card-image">
<a href="#" title="product x">
<img width="230" height="230" src="#" class="attachment-_thumbnail" alt="product x">
</a>
<div class="ripple-container"></div>
</div>
<div class="content">
<h6 class="category">Items</h6>
<h4 class="card-title">
<a class="shop-item-title-link" href="#" title="product x">product x</a>
</h4>
<div class="card-description">
<p><span>product descirption</span></p>
</div>
<div class="footer">
<div class="price">
<h4><span class="Price"><span class="Price-currencySymbol">£</span>45.00</span></h4>
</div>
<div class="stats">
<a rel="nofollow" href="#" title="Add to cart">
<i rel="tooltip" data-original-title="Add to cart" class="fa fa-cart-plus"></i>
</a>
</div>
</div>
</div>
</div>

That is a very specific target, what you want to do is use parent and sibling together.
Try something like this:
return $(el).parents().siblings('.card-title').text();

Angular *ngFor to repeat buttons with list items

I am building a web App using Angular 2 and want to loop the button with the list items but outside of list items, how can I get the functionality using *ngFor, please help.
My HTML code:
<div class="col-xs-6">
<a class="list-group-item clearfix" style="background-color:rgb(3, 0, 48)" *ngFor="let buying of buy">
<div class="pull-left" style="max-width:350px">
<h5 style="color:white">{{buying.names}}</h5>
<p style="color:white">{{buying.desc}}</p>
</div>
<div>
<span class="pull-right" >
<img [src]="buying.getImg" alt="image not loaded" class="img-responsive" style="max-height:100px">
</span>
</div>
</a>
</div>
<div class="col-xs-6"> <-----I WANT TO LOOP THIS BUTTON
<button class="btn btn-primary ; pull-right">Add To Cart</button>
</div>

Try this code snippet. I have created a div tag above linking both content and then added the loop inside that, so it will refer to both elements (item and button).
<div *ngFor="let buying of buy">
<div class="col-xs-6">
<a class="list-group-item clearfix" style="background-color:rgb(3, 0, 48)">
<div class="pull-left" style="max-width:350px">
<h5 style="color:white">{{buying.names}}</h5>
<p style="color:white">{{buying.desc}}</p>
</div>
<div>
<span class="pull-right">
<img [src]="buying.getImg" alt="image not loaded" class="img-responsive" style="max-height:100px">
</span>
</div>
</a>
</div>
<div class="col-xs-6">
<button class="btn btn-primary ; pull-right">Add To Cart</button>
</div>
</div>

keypress in appended html [duplicate]

This question already has answers here:
Event binding on dynamically created elements?
(23 answers)
Closed 7 years ago.
<input type="text" id="message" param="1" placeholder="chat here.." />
This is element inside the div which is working fine outside the javascript
here is the case after appended element
$('.chat-wrapper').append('<li class="one-big-icon mega-li mgl-10"> <span class="mega-icon"><img alt="example image" class="chat-initatior" src="'+img_url+'"></span> <span class="badge vd_bg-red">10</span> <div class="vd_mega-menu-content open-top width-xs-4 width-md-5 width-lg-4 center-xs-4 chat-box'+id+'" data-action="click-target"> <div class="child-menu"> <div class="title"> ujwal <i>(online)</i> <div class="vd_panel-menu"> <div data-rel="tooltip" data-original-title="Close" class="menu entypo-icon"> <i class="icon-cross"></i> </div> </div> </div> <div class="content-list content-image content-menu"> <div data-rel="scroll"> <ul class="list-wrapper pd-lr-10"> <li> <div class="menu-icon"><img alt="example image" src=""></div> <div class="menu-text"> Do you play or follow any sports? <div class="menu-info"> <span class="menu-date">12 Minutes Ago </span> </div> </div> </li> </ul> </div> <div class="closing chat-area"> <div class="chat-box"> <input type="text" id="message" placeholder="chat here.." /> </div> <div class="vd_panel-menu"> <div data-rel="tooltip" data-original-title="Insert Picture" class="menu"> <i class="icon-camera"></i> </div> <div data-rel="tooltip" data-original-title="Emoticons" class="menu"> <i class="fa fa-smile-o"></i> </div> </div> </div> </div> </div> <!-- child-menu --> </div> <!-- vd_mega-menu-content --> </li>');
Now when I do
$('#message').keypress(function(event){
alert('WORKING');
});
alert('working') only works when I type any key in the first element after the append is made on some click and if I type something inside that appended input box I get nothing but why?

Look at using .on() or .live() depending on your jQuery version to bind to elements that are appended.
$("div").on( "keypress", "#message", function(){
alert( "working!" );
});
where div is the selector of a parent of #message.

here work fine;

var id='one',img_url='http';//test values
$('.chat-wrapper').append('<li class="one-big-icon mega-li mgl-10"> <span class="mega-icon"><img alt="example image" class="chat-initatior" src="'+img_url+'"></span> <span class="badge vd_bg-red">10</span> <div class="vd_mega-menu-content open-top width-xs-4 width-md-5 width-lg-4 center-xs-4 chat-box'+id+'" data-action="click-target"> <div class="child-menu"> <div class="title"> ujwal <i>(online)</i> <div class="vd_panel-menu"> <div data-rel="tooltip" data-original-title="Close" class="menu entypo-icon"> <i class="icon-cross"></i> </div> </div> </div> <div class="content-list content-image content-menu"> <div data-rel="scroll"> <ul class="list-wrapper pd-lr-10"> <li> <div class="menu-icon"><img alt="example image" src=""></div> <div class="menu-text"> Do you play or follow any sports? <div class="menu-info"> <span class="menu-date">12 Minutes Ago </span> </div> </div> </li> </ul> </div> <div class="closing chat-area"> <div class="chat-box"> <input type="text" id="message" placeholder="chat here.." /> </div> <div class="vd_panel-menu"> <div data-rel="tooltip" data-original-title="Insert Picture" class="menu"> <i class="icon-camera"></i> </div> <div data-rel="tooltip" data-original-title="Emoticons" class="menu"> <i class="fa fa-smile-o"></i> </div> </div> </div> </div> </div> <!-- child-menu --> </div> <!-- vd_mega-menu-content --> </li>');
$('#message').keypress(function(event){

});

I tried following code in jquery
$(".dialogs .itemdiv .tools").live("click",function(e){
e.preventDefault();
alert('clicked on edit');
var n = $('.dialogs .itemdiv .tools a').attr('id');
alert(n);
});
I use live here because I am getting above html by using append method in jquery.

live is deprecated in later versions of jQuery - but to solve your issue you need to use an instance of this
$("#addSentiment").on("click", ".dialogs .itemdiv .tools", function(e){
e.preventDefault();
alert('clicked on edit');
var n = $("a", this).attr('id');
alert(n);
});

jQuery selectors catch the first match of their content.
To catch the n-th match, you need to use the n-th child selector, like this:
$(".dialogs .itemdiv .tools:nth-child(2)")

I am not familiar with the live method, but you should be able to do something like the following:
function addHandlers() {
$(".dialogs .itemdiv .tools a").each(function() {
$(this).click(function() {
alert('clicked on edit');
);
});
}
function yourAppendFunction() {
//your append code
//add call to a function that will create your event handlers
addHandlers();
}
The .each method runs through each and every item that fits the selection criteria, and then we use the this keyword within the function to reference what we are working on. Putting it in a function that we don't call until after you append the items ensures the html exists when you try to add the handlers you need.
