Don't understand what to do

Hi, I'm stuck on this challenge and I don't know what to do.Can anyone explain me more clear this challenge?

js/app.js 
//Create the Modal
var $modal = $("<div id='modal'></div>");

//Create a placeholder for text in the modal
var $placeHolder = $("<p id='placeHolder'></p>");
$modal.append($placeHolder);

//Create a button to dismiss modal and add it to modal
var $dismissButton = $("<button>Dismiss</button>");

//Hide modal when button is pressed
$dismissButton.click(function(){
  $modal.hide(300);
});

$("body").append($modal);

//A function to show a modal
function displayModal(message) {
  $placeHolder.text(message);
  $modal.hide();
  $dismissButton.append();
}

//Show an example modal
displayModal("Hello World!");
index.html 
<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
    <title>Modal Example</title>
</head>
<body>
    <h1>Modal Example Page</h1>

    <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/app.js" type="text/javascript" charset="utf-8"></script>

Thanks for help Dale! Can you please tell me what's wrong with this code?

Using jQuery only, add to all links with the class "external", the target attribute with the value of "_blank".

  var src = (".external").attr("target");
});```

Srdjan,

This seems like a different question than you originally asked. You might want to check this question as answered and ask your second question in a new form post.

In your code you are setting a variable 'src' equal to the target attribute of the .external class object.

Sometimes writing multiple lines can make reading the code and finding the issue easier: 

// When you click on the object containing the class external...
$('.external').on('click', function() {
  // Using the current object clicked on, and set the attribute 'target' to be '_blank' 
  this.attr('target', '_blank');
});

Best of luck!
