下面语句是没有自适应的提示，初始化后事件，或者记载结束事件，新自适应没法测试，用这个语句，改里面字体大小试试，没有测试，提供一个方案

setTimeout(function() {

var oldTitle = null;

$('td').bind('mouseover mouseout mousemove', function(event) {

var left = event.pageX;

var top = event.pageY;

var ele = event.target;

var title = ele.title;

var type = event.originalEvent.type;

if (type == 'mouseover') {

oldTitle = title;

ele.title = '';

console.log(title);

if (title.length != 0) {

var showEle = $('<div></div>', {

text: title,

class: 'showTitleBox'

}).css({

position: 'absolute',

top: top + 10,

left: left,

border: '1px solid #00cccc', // 边框

borderRadius: '5px', // 边框圆角

background: "#00cccc", // 背景色

fontFamily: 'SimHei', // 字体

fontSize: '15px' // 字体大小

})

showEle.appendTo('body');

}

} else if (type == 'mouseout') {

ele.title = oldTitle;

$('.showTitleBox').remove();

} else if (type == 'mousemove') {

$('.showTitleBox').css({

top: top + 10,

left: left

})

}

})

}, 100)
