How to set null value to variable using JavaScript or jQuery?

I'm storing an image value in the variable first_img:

var first_img = $('img[alt="example"]').attr('src');

And I want to set the value null after the button is clicked JavaScript or jQuery.

How can I do this?

***$('img[alt="example"]').click(function() {
    $(this).removeAttr('src');

 .on('click',
      function(){$(this).remove()}
  );​

Not sure I get this at all, as it sounds kinda obvious?

var first_img = $('img[alt="example"]').attr('src');

$('button').on('click', function() {
    first_img = null;
});

You could remove the src attribute when the image is clicked:

$('img[alt="example"]').click(function() {
    $(this).removeAttr('src');
});

or completely remove the <img> tag from the DOM:

$('img[alt="example"]').click(function() {
    $(this).remove();
});
