• What's the easiest way to assign a string returned from the server to a javascript string?

  - by powerboy

  The following does not work: var js_str= '<?php echo $str_from_server; ?>'; The problem is that, $str_from_server can contain any characters. If it contains single quotes or line breaks or others, the above code will break. And I do not have access to the server-side code. What's the easiest way to "escape" the contents of $str_from_server into a javascript string, and then it can be restored later?
