如果是安卓手機，調起軟鍵盤是滑動body

$("#jobInfo").delegate('input[type="text"],textarea',"focus",function () {
var u = navigator.userAgent, app = navigator.appVersion;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1; //g
if(isAndroid){
    var num = $(this).offset().top-150;
    $("html,body").animate({scrollTop:num},400);
}
});
