为什么我的高用了document.body.clientHeight高度变成了160。。html中有写两个height为100%
var WINDOW_WIDTH = document.body.clientWidth;
var WINDOW_HEIGHT = document.body.clientHeight;
var MARGINTOP = Math.round(WINDOW_HEIGHT/4);
var MARGINLEFT = Math.round(WINDOW_WIDTH/10);
var RADIUS = Math.round(WINDOW_WIDTH * 4 / 5 / 126) - 1;
var minus = getCurTime();
var balls = [];
var colors = ["#33B5E5","#0099CC","#AA66CC","#9933CC","#99CC00","#669900","#FFBB33","#FF8800","#FF4444","#CC0000"];
window.onload = function(){
var canvas = document.getElementsByTagName('canvas')[0];
var context = canvas.getContext('2d');
canvas.width = WINDOW_WIDTH;
canvas.height = WINDOW_HEIGHT;
setInterval(function(){
clock(context);
update();
},50);
}
