Escape single quotes in a string

rated 0 times [ 179] [ 6] / answers: 1 / hits: 60050 / 11 Years ago, fri, march 22, 2013, 12:00:00

JSP:

<% final String data = some test with ' single quotes; %>

<script>

    var str = '<%= data %>';

<script>

The result is (JavaScript):

var str = 'some test with ' single quotes';

Uncaught SyntaxError: Unexpected identifier

How do I replace this single quote with ' to avoid a JavaScript error?

Use escapeEcmaScript method from Apache Commons Lang package:

Escapes any values it finds into their EcmaScript String form. Deals
correctly with quotes and control-chars (tab, backslash, cr, ff, etc.).
So a tab becomes the characters '\' and 't'.

The only difference between Java strings and EcmaScript strings is
that in EcmaScript, a single quote and forward-slash (/) are escaped.

Example:

input string: He didn't say, Stop!

output string: He didn't say, Stop!
