$('textarea').each(function () {
    //浏览器不兼容的情况下的获取方式
    var oHeight=this.scrollHeight==0?$(this).height:this.scrollHeight;
    this.setAttribute('style', 'height:' + oHeight + 'px;overflow-y:hidden;');
    //正常情况下           
    this.setAttribute('style', 'height:' + this.scrollHeight + 'px;overflow-y:hidden;');
}).on('input', function () {
    this.style.height = 'auto';
    this.style.height = (this.scrollHeight) + 'px';
});
