JQuery平滑滚动到DIV内的位置,隐藏溢出

var offset = 0; // current scrolling "amount"
$('#right-arrow').click(function() {
    offset += (50 * 5); // add a @R_667_10586@l width of 5 items to the scrolling amount

    if (offset > (number_of_dates * 50)) {
        offset = number_of_dates * 50; // don't exceed this limit
    }

    $('#div-to-scroll').animate({
        'margin-left': '-' + offset + 'px'
    });
});


$('#left-arrow').click(function() {
    offset -= (50 * 5);

    if (offset < 0) {
        offset = 0; // don't exceed this limit
    }

    $('#div-to-scroll').animate({
        'margin-left': offset + 'px'
    });
});
