var ctx = canvas.get(0).getContext("2d");canvas.attr("width",$(window).get(0).innerWidth);canvas.attr("height",$(window).get(0).innerHeight);$(window).resize(resizeCanvas);function resizeCanvas(){? ? ?canvas.attr("width",$(window).get(0).innerWidth);? ? ?canvas.attr("height",$(window).get(0).innerHeight); ? ??};
var ctx = canvas.get(0).getContext("2d")；我就想知道這get（0）啥意思啊
