先加载Jquery文件
jQuery(document).ready(function($){
$("html,body").click(function(e){
var y = new Array("+","-","*","/");
var n=Math.round(Math.random()*100)+1;
var i= 0;
var s = '';
while(i < Math.round(Math.random()*8)+1){
s = s + Math.round(Math.random()*100)+1 + y[Math.round(Math.random()*3)];
i = i + 1;
}
s = s + n;
var $i=$("").text(s+"="+eval(s));
var x=e.pageX,y=e.pageY;
$i.css({
"z-index":99999,
"top":y-20,

});
$("body").append($i);
$i.animate(
