javascript - jquery unterminated string literal when loading dynamic content -

$str loading dynamic content admin panel (tinymce) in following format  $str = 'first line     second line     third line';  when try access variable gives me unterminated string literal   <script type="text/javascript">     $(document).ready(function() {         var = '<?php echo $str;?>';         $('#abc').html(a);                           });     </script> <div id="abc"></div> 

when convert string $str = 'first line second line third line'; not give error string in above way.

when dumping php variable javascript, use json_encode. this:

var = <?php echo json_encode($str); ?>; 

note no quotes around php code, important! php add quotes , escape correctly.
