javascript调用对象属性方式
javascript调用对象属性可以用<对象.属性>或者用<对象['属性']>。代码示例如下：

       function init(){ var Point = function(){var x;var y;this.setX = function(x){this.x = x;}this.setY = function(y){this.y=y;} }var point1 = new Point();        point1.setX("121.00");point1.setY("31.00");alert("point1>> x:"+point1.x+"y:"+point1.y);var point2 = new Point();        point2.x = "122.00";point2.y = "32.00";alert("point2>> x:"+point2.x+"y:"+point2.y);var point3 = new Point();point3['x']="123.00";point3['y'] = "33.00";point3['address'] = "china";alert("point3>> x:"+point3['x']+"y:"+point3['y']+"address:"+point3['address']); }
