target="_blank" causes a link to open in a new window.

You don't have a link. You have an anchor element with an onclick attribute which runs some JavaScript. (You should be using a <button> element since you don't have an actual link, better yet , have a link to a URL which replicates the effects of the JS server side).

In order to get it to open a new window, you will have to modify your JavaScript (we can't see the editView function so it is hard to say precisely how) to make use of the open method .

You are generating a form which takes no user input and just has fixed data. The easiest way to deal with this is to just us a form in the first place.

<form method="post" 
      action="<?php echo base_url(); ?>home/editData"
      target="_blank">
    <input type="hidden" name="id" value="<?php echo $detail->id;?>">
    <button class="btn button_style">Edit</button>
</form>

Forget about JavaScript. Add CSS to style the form (eg display: inline; margin: 0; padding: 0 ) and button to taste.
