我一直在尝试使用单击按钮使 jquery 在文本框中滚动文本，但它在 IE、Chrome 或 Firefox 中不起作用。
我希望我的文本框在单击按钮时手动向下滚动。
<!DOCTYPE html>
<html>
<head>
<script src="http://localhost:62240/Scripts/jquery-2.1.1.js"></script>
<script>
x = 0;
$(document).ready(function () {
$("div").scroll(function () {
$("span").text(x += 1);
});
$("button").click(function () {
$("div").scroll();
});
});
</script>
</head>
<body>
<p>Try the scrollbar in the div</p>
<div style="border:1px solid black;width:200px;height:100px;overflow:scroll;">
In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since.
<br><br>
'Whenever you feel like criticizing anyone,' he told me, just remember that all the people in this world haven't had the advantages that you've had.'
</div>
<p>Scrolled <span>0</span> times.</p>
<button>Trigger scroll event for the window</button>
</body>
</html>
最佳答案
scroll() 是当 div 滚动时触发的事件。如果您想通过单击按钮进行滚动，请尝试以下操作:
x = 0;
$(document).ready(function () {
$("button").click(function () {
$('div').animate({ scrollTop: (x+1)*20 }, 200);
$("span").text(x += 1);
});
});
