New issue 23 by b.l.stein: String treated as array (JavaScript version)
http://code.google.com/p/json-template/issues/detail?id=23
Given the following template fragment
{.section term}
{.repeated section @}
<li>{...@}</li>
{.or}
<li>{...@}</li>
{.end}
{.end}
The following input works as expected:
{term: ['one', 'two', 'three'] }
The following input however does not:
{term: 'one'}
On Firefox the string is treated as an array and returns a list element for
each character. On Internet Explorer it throws an error. The expected
result would have been to call the {.or} section of the template and only
produce a single list element.
The problem occurs on line 276 of json-template.js (210 2009-04-30), where
the code assumes that if the object exists and has a length value greater
than zero it will repeat the section:
if (items && items.length > 0)
Changing this line to test for the presence of an array fixes the error and
produces the expected result. The resulting fix is as follows:
if (items && Object.prototype.toString.apply(items) === '[object Array]'
&& items.length > 0)
