11 * Provides Y.QueryString.stringify method for converting objects to Query Strings.
14 * @submodule querystring-stringify
17 var QueryString = Y.namespace("QueryString"),
22 * Provides Y.QueryString.escape method to be able to override default encoding
23 * method. This is important in cases where non-standard delimiters are used, if
24 * the delimiters would not normally be handled properly by the builtin
25 * (en|de)codeURIComponent functions.
26 * Default: encodeURIComponent
32 QueryString.escape = encodeURIComponent;
35 * <p>Converts an arbitrary value to a Query String representation.</p>
37 * <p>Objects with cyclical references will trigger an exception.</p>
42 * @param obj {Variant} any arbitrary value to convert to query string
43 * @param cfg {Object} (optional) Configuration object. The three
44 * supported configurations are:
45 * <ul><li>sep: When defined, the value will be used as the key-value
46 * separator. The default value is "&".</li>
47 * <li>eq: When defined, the value will be used to join the key to
48 * the value. The default value is "=".</li>
49 * <li>arrayKey: When set to true, the key of an array will have the
50 * '[]' notation appended to the key. The default value is false.
52 * @param name {String} (optional) Name of the current key, for handling children recursively.
