我希望有人可以指出正确的方向。
我基本上是试图构建一个OOP解决方案,以基于一个类动态生成许多对象,然后能够通过类方法运行与每个对象相关联的方法。
下面是我的非动态代码。
// Create videoObject class
function videoObject(videoTag, videoNum){
this.videoTag = videoTag;
this.videoNum = videoNum;
this.videoTagHref = videoTag.attr("href");
this.videoId = function(videoTag){
};
this.addAttrId = function(videoNum){
};
this.printObjectInfo = function(videoId){
};
this.embedVideo = function(videoId, videoTag, videoNum){
};
this.buildControls = function(videoTag){
};
};
// Manually create two objects and run class methods
var newVideo1 = new videoObject($('.yt-player-0'), 0);
newVideo1.videoId();
newVideo1.addAttrId();
newVideo1.embedVideo();
newVideo1.buildControls();
var newVideo2 = new videoObject($('.yt-player-1'), 1);
newVideo2.videoId();
newVideo2.addAttrId();
newVideo2.embedVideo();
newVideo2.buildControls();
// I want to somehow create newVideo1 and newVideo2 dynamically inside a loop like below
var length = $('.yt-player').length;
for (var i = 0; i < length; i++) {
}
大家能给我的任何帮助将不胜感激。
谢谢,
汤姆
我会尝试这个(未经测试的):
// Create videoObject class
function videoObject(videoTag, videoNum){
this.videoTag = videoTag;
this.videoNum = videoNum;
this.videoTagHref = videoTag.attr("href");
this.videoId = function(videoTag){
};
this.addAttrId = function(videoNum){
};
this.printObjectInfo = function(videoId){
};
this.embedVideo = function(videoId, videoTag, videoNum){
};
this.buildControls = function(videoTag){
};
// call these methods in your constructor instead of repeatedly from elsewhere
this.videoId();
this.addAttrId();
this.embedVideo();
this.buildControls();
// send back a reference to this newly created video object to the loop
return this;
};
// create an array of video object references
var videoObjectReferences = [];
for (var i=0;i<10;i++){
// building ten video objects here, with ids of: yt-player-0, yt-player-1, etc.
// build a selector to reference them via id, not by class with a dot as you have in your question
var sel = String("#yt-player-" + i);
// create the object and store a reference to the video object so you can do something with it later
var newVid = new videoObject($(sel), i);
// build list of references
videoObjectReferences.push(newVid);
}
