Open .pdf files in new tab and not download - Javascript

Question

I have a quick question, I have my javaScript code setup where it downloads any ".pdf" files that I have on my JavaScript table. How do I make it where it doesn't download the file, but instead opens it up in a new tab?

Here is the code:

JavaScript file: o365FileSlide.js

$(document).ready(function(){
	var current_title = $(document).attr('title');
	
	if(current_title == 'Introduction to OneDrive')
		getOneDriveFiles();
});

function getOneDriveFiles(){
	//PnP call here

	$pnp.setup({
		baseUrl: "/TrainingResourceCenter/O365Training/"
	});

	$pnp.sp.web.getFolderByServerRelativeUrl("/TrainingResourceCenter/O365Training/Shared Documents/OneDrive/").files.orderBy("Title").get().then(function(f){
		console.log(f);
		
		var files = '';
		
		$.each(f, function(index, value){
			var filesHtml = "<div class='file'>" + 
							"<a href='" + value.ServerRelativeUrl + "'><img src='/O365Training/PublishingImages/wordThumbSmall.png' width='75px' height='75px' /></a>" + 
							"<a href='" + value.ServerRelativeUrl + "'><p id='fileTitle' margin-top: 10px>" + value.Title + "</p></a>" + 
							"</div>";
			
			files = files + filesHtml;
		});
		
		$(".files").append(files).window.open(files);
		
	});
}

<div id="filesDiv" class="row" style="padding-left: 15px;">
    <div class="files" target="_blank"></div>
</div>

<script type="text/javascript" src="/publiccdnlib/apps/O365-Slider/o365FileSlide.js"></script>

If anyone could give me some pointers, I would really appreciate it! Thanks.
