Uncaught TypeError: Illegal constructor – Using Bonsai.JS in Backbone.JS
提问by ac360
I'm still new to js and I'm trying to fit bonsai.js into a backbone app.
我还是 js 的新手，我正在尝试将 bonsai.js 放入一个主干应用程序中。
I'm following this guide here: https://github.com/iamdustan/bonsai-demos, and trying to 'Separate Things Out' by putting the animation into a separate file titled hero-animation.js, but I get an Uncaught TypeError: Illegal constructoron the first line of hero-animation.js
我在这里遵循本指南：https: //github.com/iamdustan/bonsai-demos，并尝试通过将动画放入名为 的单独文件来“分离事物” hero-animation.js，但我Uncaught TypeError: Illegal constructor在第一行得到hero-animation.js
This is called in my Backbone router, and is working fine...
这在我的骨干路由器中被调用，并且工作正常......
homeAnimation: function() {
bonsai.run(document.getElementById('heroContent'), {
url: 'hero-animation.js',
width: 500,
height: 400
});
}
Here is what I have in hero-animation.js which is resulting in an error on line 1:
这是我在 hero-animation.js 中的内容，导致第 1 行出现错误：
var rect = new Rect(0, 0, 200, 200);
rect
.fill('random')
.addTo(stage)
.attr({
x: stage.width - rect.attr('width'),
y: stage.width - rect.attr('height')
})
.animate('0.5s', {
x: 0,
y: 0
});

Seems like you forgot to include bonsai.js.
好像你忘了包括bonsai.js.
Initially, Rectis an "interface", which means it can't be used as a constructor, and Bonsai overrides it for its own purposes.
最初，Rect是一个“接口”，这意味着它不能用作构造函数，并且 Bonsai 出于自己的目的覆盖它。
