micro tpl 极小的模板系统，支持数据递归

micro-tpl.js

var microTpl = {
	render: function (tpl, data) {
		if(!tpl || !data) {
			throw new Error("tpl or data can't be empty, microlTpl.render");
		}

		// 占位符的正则 the regex of placeholder
		var rendered,
			rPlaceholder = /\{([^}]+)\}/g,
			

		rendered = tpl.replace(rPlaceholder, function (m, key) {
			var result,
				stack = key.split('.');

			result = data;
			while(key = stack.shift()){
				result = result[key];
			}
			return result;
		});
		
		return rendered;
	}
}
