[javascript] Adding close button in div to close the box

I have created a URL preview box for the entered URL.

Preview is shown in the div box. I want to add a close option on the right top. How could be done so that when users click on its box should be disabled?

Here is my fiddle.

<a class="fragment" href="google.com">
    <div>
    <img src ="http://placehold.it/116x116" alt="some description"/> 
    <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
    <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
    </p>
</div>
</a>

code is inside php

You can use this jsFiddle

And HTML:

<div id="previewBox">
    <button id="closeButton">Close</button>
<a class="fragment" href="google.com">
    <div>
    <img src ="http://placehold.it/116x116" alt="some description"/> 
    <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
    <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
    </p>
</div>
</a>
</div>

With JS (jquery required):

$(document).ready(function() {
    $('#closeButton').on('click', function(e) { 
        $('#previewBox').remove(); 
    });
});

Here's the updated FIDDLE

Your HTML should look like this (I only added the button):

<a class="fragment" href="google.com">
    <button id="closeButton">close</button>
    <div>
        <img src ="http://placehold.it/116x116" alt="some description"/> 
        <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
        <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
        </p>
    </div>
</a>

and you should add the following CSS:

.fragment {
    position: relative;
}
#closeButton {
    position: absolute;
    top: 0;
    right: 0;
}

Then, to make the button actually work, you should add this javascript:

document.getElementById('closeButton').addEventListener('click', function(e) {
    e.preventDefault();
    this.parentNode.style.display = 'none';
}, false);

We're using e.preventDefault() here to prevent the anchor from following the link.

it's easy with the id of the div container : (I didn't put the close button inside the <a> because that's does work properly on all browser.

<div id="myDiv">
<button class="close" onclick="document.getElementById('myDiv').style.display='none'" >Close</button>
<a class="fragment" href="http://google.com">
    <div>
    <img src ="http://placehold.it/116x116" alt="some description"/> 
    <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
    <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
    </p>
</div>
</a>
</div>

Updated your fiddle: http://jsfiddle.net/xftr5/11/ Hope, everything is clear?

$(document).ready(function() {
    $('.fragment i').on('click', function(e) { $(e.target).closest('a').remove(); });
});

Added jQuery and inserted an <i> as close trigger...

jQuery("#your_div_id").remove(); will completely remove the corresponding elements from the HTML DOM. So if you want to show the div on another event without a refresh, it will not be possible to retrieve the removed elements back unless you use AJAX.

jQuery("#your_div_id").toggle("slow"); will also could make unexpected results. As an Example when you select some element on your div which generates another div with a close button(which uses the same close functionality just as your previous div) it could make undesired behaviour.

So without using AJAX, a good solution for the close button would be as follows

HTML____________

<div id="your_div_id">
<span class="close_div" onclick="close_div(1)">&#10006</span>
</div>

JQUERY__________

function close_div(id) {
    if(id === 1) {
        jQuery("#your_div_id").hide();
    }
}

Now you can show the div, when another event occures as you wish... :-)

A jQuery solution: Add this button inside any element you want to be able to close:

<button type='button' class='close' onclick='$(this).parent().remove();'>×</button>

or to 'just' hide it:

<button type='button' class='close' onclick='$(this).parent().hide();'>×</button>
