Browse - programming tips - javascript safely parse json in any browser

Q.  How can I safely parse JSON in any browser?

A.  Many browsers have a JSON.parse() function which is the best thing
to use.  But not all.  So use this function:

function parseJson(json) {
	var	out;

	try
	{
		if (typeof JSON == 'object' && typeof JSON.parse == 'function') {
			 out = JSON.parse(json);
		}
		else {
			out = eval('('+json+')');
		}
	}
	catch(e) {
		// do nothing
	}

	return out;
}
