++复制代码++ 代码如下:

var fontSize = $(this).attr('style',function(i,s){
return s.replace(/font-size:\s*(\d+.{0,1}\d*)/, function(a){
return a + 'px';
});
});
//console.debug("font-size: "+ $(this).attr('style').match(/(?:font-size:)s*(\d+.{0,1}\d*)/));

var style = $(this).attr('style');
var fontSize = $(this).css('font-size',function(){
var s = style.match(/(?:font-size:)s*(\d+.{0,1}\d*)/)[0].replace(/font-size:/,'');
return s;
});
