本文介绍了如何扩展KineticJS的形状的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
对于KineticJS版本 4.0.0 或更少,形状扩展了一个类,可以扩展
For KineticJS version 4.0.0 or less a shape extended a class and could be extended by
var MyCircle = Kinetic.Circle.extend({
init : function(config) {
this._super(config));
},
myFunc : function(){}
});
或
Kinetic.MyCircle = function (config) {
Kinetic.Circle.apply(this, [config]);
};
Kinetic.MyCircle .prototype = {
myFunc: function () {}
};
Kinetic.GlobalObject.extend(Kinetic.MyCircle , Kinetic.Circle);
在版本 4.0.1 中,他们将依赖关系删除到类实用程序,
In version 4.0.1 they removed the dependencies to the class utility and implemented a custom solution that is supposed to be much faster.
如何用新的解决方案扩展形状?
How does one extend a shape with the new solution?
推荐答案
Kinetic.GlobalObject变成Kinetic.Global(> 4.0.1),然后
Kinetic.Global现在是 Kinetic.Util (2013版),这里是一个解决方案:
Kinetic.GlobalObject became Kinetic.Global (>4.0.1), then
Kinetic.Global is now Kinetic.Util (2013 versions), here is a solution:
(function() {
Kinetic.MyCircle = function(config) {
this._initMyCircle(config);
};
Kinetic.MyCircle.prototype = {
_initMyCircle: function(config) {
Kinetic.Circle.call(this, config);
},
myFunc : function(){
}
};
Kinetic.Util.extend(Kinetic.MyCircle, Kinetic.Circle);
})();
