我是靠谱客的博主感性萝莉，最近开发中收集的这篇文章主要介绍js 弹出虚拟键盘修改密码的简单实例，觉得挺不错的，现在分享给大家，希望可以做个参考。
概述

实例如下：
//定义当前是否大写的状态
window.onload=
  function()
  {
    password1=null;    
    initCalc();
  }

var CapsLockValue=0;

var check;
function setVariables() {
tablewidth=630; // logo width, in pixels
tableheight=20; // logo height, in pixels
if (navigator.appName == "Netscape") {
horz=".left";
vert=".top";
docStyle="document.";
styleDoc="";
innerW="window.innerWidth";
innerH="window.innerHeight";
offsetX="window.pageXOffset";
offsetY="window.pageYOffset";
}
else {
horz=".pixelLeft";
vert=".pixelTop";

styleDoc=".style";
innerW="document.body.clientWidth";
innerH="document.body.clientHeight";

  }
}

evalMove();
}
