Method Detail

minify

public static String minify(String jsonish)

Renders JSON-like content safe for use with Javascript eval.

The output is a Javascript expression, not a statement, so if it contains an object ({properties}) then it still needs to be wrapped in parentheses before being passed to eval as via eval('(' + s + ')') or eval('0,' + s).

Parameters:

jsonish - a string of JSON-like content as defined by JsonSanitizer.

Returns:

a valid Javascript expression that has no free variables and whose execution will have no side-effects, and which can be embedded safely in an HTML <script></script> element or inside an XML <![CDATA[...]]> section.

minify

public static String minify(String jsonish,
                            int maximumNestingDepth)

Same as minify(String), but allows to set custom maximum nesting depth.

Parameters:

jsonish - a string of JSON-like content as defined by JsonSanitizer.

maximumNestingDepth - the maximum nesting depth for the JsonSanitizer

Returns:

see minify(String)
