这里是 jsfiddle： http: //jsfiddle.net/vZMyS/ 编辑：感谢 Buck Doyle，我用不同版本的 chrome 和 firefox/opera 脚本做了一个适当的 if else。现在它只是不适用于 IE。

脚本应该使用户能够向下/向上滚动到“var scrollKeys”中指定的滚动点，使用向上/向下键盘键，它在 chrome 中工作，但在其他浏览器中不起作用。

知道这里有什么问题吗？我如何修复此代码以使其在 firefox/opera/ie8+ 中工作？

html

<div class="big">
<div class="box1">
    <input type="text" name="input1" class="input1" />
</div>
<div class="box2">
    <input type="text" name="input2" class="input1" />
</div>
<div class="box1">
    <input type="text" name="input3" class="input1" />
</div>
<div class="box2">
    <input type="text" name="input4" class="input1" />
</div>
</div>​

css

.big {width:400px; height:4000px; float:left;}
.box1 {width:400px; height:1000px; background-color:#ccc; float:left;}
.box2 {width:400px; height:1000px; background-color:#ddd; float:left;}
.input1 {width:120px; height:16px; float:left;}

javascript

var scrollKeys = new Array('0', '1000', '2000', '3000');
$('body').on('keyup', function(event) {
    var keypressed = (event.which) ? event.which : event.keyCode;
    var curScroll = $('body').scrollTop();
    var keys = scrollKeys.length;
    var moved = false;
    for (i = 0; i < keys; i++) {
        //console.log(scrollKeys[i]);
        if (moved == false) {
            if (keypressed == 40 && i != (keys - 1) && parseInt(scrollKeys[i]) < curScroll && parseInt(scrollKeys[i + 1]) > curScroll) {
                $('body').animate({
                    scrollTop : (parseInt(scrollKeys[i + 1]))
                }, 'fast', function() {});
                console.log('down');
                moved = true;
            } else if (keypressed == 38 && i != 0 && parseInt(scrollKeys[i]) > curScroll && parseInt(scrollKeys[i - 1]) < curScroll) {
                $('body').animate({
                    scrollTop : (parseInt(scrollKeys[i - 1]))
                }, 'fast', function(){});
                console.log('up');
                moved = true;
            }
        }
    }
});​

Here is a fork of your fiddle that works in Firefox. But now it doesn’t work in Chrome. The important thing is that I changed it to scroll html instead of body.
