使用Javascript以编程方式掀起波澜

问题描述：

这有效，但我希望它像波浪一样.它应该看起来像实际的波浪，而不是"v"形.您如何逐步做到这一点?

This works but I want it to be like a wave. Rather than a 'v' shape, it should look like an actual wave. How do you gradually do this?

var height = 0;

setInterval(function () {
    $('#container').prepend('<div style="height:' + Math.abs(height++) + '%"></div>');
    height = (height == 100) ? -100 : height;
}, 10);

我的CSS:

html, body, #outerContainer, #container {
    height:100%;
}
#outerContainer {
    display : table;
}
#container {
    display : table-cell;
    vertical-align:bottom;
    white-space:nowrap;
}
#container > div {
    width:5px;
    background:black;
    display:inline-block;
}

答

只需使用

Just use Math.sin() to model the wave.

更新示例

var i = 5, height = 0;
setInterval(function () {
    $('#container').prepend('<div style="height:' + height + '%"></div>');
    i += 0.05;
    height = 50 * Math.sin(i) + 50;
}, 10);

如果要使波形更平滑，请减小增量值和元素的宽度.这是一个示例.

If you want to make the wave smoother, decrease the increment value and the width of the elements. Here is an example.
