Solution

...i want to ask the user when a user wants to remove a post ,( agree or disagree ) if selected agree(ok) then the post will be remove , if selected disagree (cancel) do nothing with the post

In order to achieve the desired result you need to change a bit your html in order to pass the current element (refer: this keyword) and like reported in the examples section you can attach to the window object a function called showAlert:

window.showAlert = function(msg, title, ele) {
    var that = ele;
    alertify.prompt(msg, title,
            function(evt, value){
                ele.closest('div').remove();
            },
            function(){
                // do nothing 
            });
}

And change your button to:

<button onclick="return showAlert('are you sure you want to delete',  '{{obj.title}}')".....

<script src="//cdn.jsdelivr.net/npm/alertifyjs@1.13.1/build/alertify.min.js"></script>
<link rel="stylesheet" href="//cdn.jsdelivr.net/npm/alertifyjs@1.13.1/build/css/alertify.rtl.min.css"/>
<script type="text/javascript">
window.showAlert = function(msg, title, ele) {
    var that = ele;
    alertify.prompt(msg, title,
            function(evt, value){
                ele.closest('div').remove();
            },
            function(){
                // do nothing
            });
}
</script>


<div>
    <p> This is the first post</p>
    <button onclick="return showAlert('are you sure you want to delete',  'post n. 1', this)">Click Me</button>
</div>

<div>
    <p> This is the second post</p>
    <button onclick="return showAlert('are you sure you want to delete',  'post n. 2', this)">Click Me</button>
</div>
<div>
    <p> This is the third post</p>
    <button onclick="return showAlert('are you sure you want to delete',  'post n. 3', this)">Click Me</button>
</div>
