我为一些动画创建了一些类/对象。我创建了一个名为Navigation()的类,以及另一个名为Stars()的类。每个类都有自己的方法和与之关联的对象。我在Navigation()类中创建了一个方法,该方法尝试运行方法和与之关联的对象。 Navigation类方法不会运行Stars方法。我再次没有使用导航类对象调用Stars Class方法。我试图从导航类方法中调用Stars对象的方法,如果这是有道理的。我是OOP javascript的新手,我很难知道这个问题的术语来研究它。如果有任何其他讨论,文章或线索指出我也会非常感激。或者只是问题的一般答案。
//Problem is in the Navigation class method spaceWarp()
function Navigation(selector){//Navigation Class
this.selector = selector;
this.spaceWarp = function(selector1,selector2,speed1,speed2,speed3,speed4,delay1,delay2){//spaceWarp Method function
var button = $(selector);
var starFrame =$(selector1);
var frameSpeed = speed1;
var delay1 = delay1;
var spaceBK = $(selector2);
var bkTime = speed2;
var starSpeed = speed3;
var delay2 = delay2;
var stopStarSpeed = speed4;
button.click(function(){
starFrame.velocity({'top': '0vh'},frameSpeed);//works
setTimeout(function () {
spaceBK.velocity('fadeIn',{duration: bkTime});//works
stars1.flyingStars(starSpeed);//does not work
stars2.flyingStars(starSpeed * 1.5);//does not work
stars3.flyingStars(starSpeed * 2.5);//does not work
}, delay1);
setTimeout(function () {
stars1.stopStars(stopStarSpeed);//does not work
stars1.stopStars(stopStarSpeed);//does not work
stars1.stopStars(stopStarSpeed);//does not work
}, delay2);
});
};//End spaceWarp Method
}//End Navigation Class
function Stars(selector){//Star Class
this.selector = selector;
this.stopStars = function(speed){//stopStars method
var object = $(selector);
object.css('background-position-y', '0vh');
object.velocity({'background-position-y': '100vh'},speed,'easeOutCubic');
object.velocity('stop');
};
this.flyingStars = function(speed){
var self = this;
var object = $(self.selector);
var callback = function(){self.flyingStars(speed);};
object.css('background-position-y', '0vh');
object.velocity({'background-position-y': '100vh'},speed,'linear',callback);
};
}//End Star Class
//Initialize objects
var spaceButton = new Navigation('#spaceWarp');
var stars1 = new Stars('#stars1');
var stars2 = new Stars('#stars2');
var stars3 = new Stars('#stars3');
//run object
spaceButton.spaceWarp('#starFrame','#spaceBK','3000','3500','3000','6000','2100','7000');

欢迎来到javascript的世界,你不用它来画画和移动盒子:))
来到你的问题:
//Initialize objects
var spaceButton = new Navigation('#spaceWarp');
var stars1 = new Stars('#stars1');
var stars2 = new Stars('#stars2');
var stars3 = new Stars('#stars3');
对象的初始化很棒,但这是挑战。您如何使stars1
,stars2
和stars3
可用于spaceButton对象?在该对象stars1
的范围内,stars2
和stars3
是未定义的变量。如果您的对象是全局可用的,请通过此运算符进行检查。
通过starsX
this.starsX
对象
您需要使用三个引用更新您的函数。
this.spaceWarp = function(selector1,selector2,speed1,speed2,speed3,speed4,delay1,delay2, stars1, stars2, stars3){//spaceWarp Method function
var button = $(selector);
var starFrame =$(selector1);
var frameSpeed = speed1;
var delay1 = delay1;
var spaceBK = $(selector2);
var bkTime = speed2;
var starSpeed = speed3;
var delay2 = delay2;
var stopStarSpeed = speed4;
var stars1 = stars1;
var stars2 = stars2;
var stars3 = stars3;
button.click(function(){
starFrame.velocity({'top': '0vh'},frameSpeed);//works
setTimeout(function () {
spaceBK.velocity('fadeIn',{duration: bkTime});//works
stars1.flyingStars(starSpeed);//does not work
stars2.flyingStars(starSpeed * 1.5);//does not work but now starsX exists
stars3.flyingStars(starSpeed * 2.5);//does not work
}, delay1);
setTimeout(function () {
stars1.stopStars(stopStarSpeed);//does not work
stars1.stopStars(stopStarSpeed);//does not work
stars1.stopStars(stopStarSpeed);//does not work
}, delay2);
});
};//End spaceWarp Method
通过传递starsX
个对象
spaceButton.spaceWarp('#starFrame','#spaceBK','3000','3500','3000','6000','2100','7000', stars1, stars2, stars3);
