闲得蛋疼，JavaScript版本BadApple
参考Vim版本的BadApple改写而成。由于加载数据比较大，可能网速不给力的童鞋效果不太好，多刷新几次就好了，^_^。
运行环境：支持HTML5 Canvas的浏览器。
1. 代码：
$(function() {
var BadApple = {
is_running: false,
data_index: 0,
data_count: 67,
is_loading: {},
progress: $('#progress'),

me.data_matrix = [];
for (i = 0; i < me.frame_row; ++i) {
me.data_matrix[i] = Array(me.frame_col).join(' ').split('');
}
me.canvas = stage.get(0);
me.ctx = me.canvas.getContext('2d');

},

// update progress
me.progress.html((index / me.data_count * 100).toFixed(2) + '%');
