js 判断两个对象是否相等

	//判断两个对象是否相等
	function isObjectValueEqual(a, b) {
        // Of course, we can do it use for in 
        // Create arrays of property names
        var aProps = Object.getOwnPropertyNames(a);
        var bProps = Object.getOwnPropertyNames(b);
     
        // If number of properties is different,
        // objects are not equivalent
        if (aProps.length != bProps.length) {
            return false;
        }
     
        for (var i = 0; i < aProps.length; i++) {
            var propName = aProps[i];
     
            // If values of same property are not equal,
            // objects are not equivalent
            if (a[propName] !== b[propName]) {
                return false;
            }
        }
     
        // If we made it this far, objects
        // are considered equivalent
        return true;
    }
