我正在尝试使用http://ejohn.org/blog/processingjs/处的 javascript 处理端口我想使用以下构造函数。Processing(CanvasElement, "some massive block of code");
我知道 javascript 本身并不支持多行字符串,但是有没有办法传递类似下面的内容而不必连接每一行并转义每个特殊字符?
/**
* Array.
*
* An array is a list of data. Each piece of data in an array
* is identified by an index number representing its position in
* the array. Arrays are zero based, which means that the first
* element in the array is [0], the second element is [1], and so on.
* In this example, an array named "coswav" is created and
* filled with the cosine values. This data is displayed three
* separate ways on the screen.

float[] coswave = new float[width];
for (int i = 0; i < width; i++) {
float amount = map(i, 0, width, 0, PI);
coswave[i] = abs(cos(amount));
}
for (int i = 0; i < width; i++) {
stroke(coswave[i]*255);
line(i, 0, i, height/3);
}

stroke(coswave[i]*255 / 4);
line(i, height/3, i, height/3*2);
}

stroke(255 - coswave[i]*255);
line(i, height/3*2, i, height);
