js 生成32位 UUID

function uuidGenerator() {
	var originStr = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
		originChar = '0123456789abcdef',
		len = originChar.length;
	return originStr.replace(/x/g, function(match) {
		return originChar.charAt(Math.floor(Math.random() * len))
	})
}
			
console.log(uuidGenerator());
