Trying to call js function from php and pass php html string as argument

Here is the problem which I am facing.

 echo "<script type='text/javascript'>window.insertCartInHeader({$cart});</script>";

$cart variable is holding HTML block of code. I get Uncaught SyntaxError: Unexpected token <

Solution?

window.insertCartInHeader = function(cart){ 
    console.log(cart)
    var list = $("#top-links").append('<ul id="cart-header"></ul>').find('#cart-header');
    list.append('<li>'+cart+'</li>');
}

Here is the string which I am passing

'<div id="cart">


  <button type="button" data-toggle="dropdown" data-loading-text="Loading..." class="heading dropdown-toggle">

  <div class="pull-left flip"><h4></h4></div><span id="cart-total">0 item(s) - £0.00</span></button>


  <ul class="dropdown-menu">


    <li>

      <p class="text-center">Your shopping cart is empty!</p>

    </li>


  </ul>

</div>

' (length=402)

You need to add quotes ("), to let javascript know it's a string, and you should use addslashes, since you may have classes or attributes in that html.

echo "<script type='text/javascript'>window.insertCartInHeader(\"". addslashes($cart) . "\");</script>";

Without addslashes something like this, won't work:

$html = '<h1 class="hi">It works</h1>';

For multiline html, this should work.

str_replace("\n", "\\", addslashes($cart));

You can improve that replace, but you get the idea.
