用了修改提示样式的JS，结果用\n换行不生效了

需要怎么改一下JS？

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 = $('', {

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: "#ff0000",       // 背景色

fontFamily: 'SimHei',        // 字体

fontSize: '20px' ,            // 字体大小

color: '#ffffff'

})

showEle.appendTo('body');

}

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

ele.title = oldTitle;

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

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

$('.showTitleBox').css({

top: top + 10,

left: left

})

}

})
