我不确定这是怎么回事,但是我在视频的左上方有一个javascript切换按钮,用于交换视频嵌入源并将切换的隐藏式字幕文本从“ cc on”到“ cc off”并返回...,但只有在初次点击后才能使用。我在这里想念什么?
控制台在页面加载时显示“未定义的按钮”,但是我不确定哪个不正确。
HTML:
<div class="navbar">
<button id="togglecc" value="OFF" onclick="toggle(this);">cc on</button>
</div>
<div id="player">
<div id="la1-video-player" data-embed-id="87e859b2-5db8-4ad8-bac7-575c22288930"></div>
<script type="application/javascript" src="https://control.livingasone.com/webplayer/loader.min.js"></script>
</div>
脚本:
function toggle(button) {
v = document.getElementById("togglecc");
vp = document.getElementById("player");
if (v.value == "ON") {
v.value = "OFF";
v.innerHTML = 'cc off';
vp.innerHTML = '<div id="la1-video-player" data-embed-id="9257a531-25ce-48bd-821b-9335681c45d8"></'+'div>';var a=document.createElement("script");a.setAttribute("src","//control.livingasone.com/webplayer/loader.min.js");document.getElementById('player').appendChild(a);
} else {
v.value = "ON";
v.innerHTML = 'cc on';
vp.innerHTML = '<div id="la1-video-player" data-embed-id="87e859b2-5db8-4ad8-bac7-575c22288930"></'+'div>';var a=document.createElement("script");a.setAttribute("src","//control.livingasone.com/webplayer/loader.min.js");document.getElementById('player').appendChild(a);
}
}

这是您更新的小提琴
同样,您应该避免在按钮元素上调用函数
%%timeit
s = df['Data'].isnull()
df['sum'] = df.groupby(s.cumsum())['Data'].cumsum().where((~s) & (s.shift(-1)))
4.52 ms ± 901 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%%timeit
g = df.reset_index().groupby(df['Data'].isnull().cumsum())
df['sum'] = g['Data'].cumsum().where(lambda x: x.index == g['index'].transform('idxmax'))
8.52 ms ± 1.45 ms per loop (mean ± std. dev. of 7 runs, 100 loops each)
%%timeit
blocks = df['Data'].isnull().cumsum()
m = blocks.duplicated(keep='last')
df['sum'] = df.groupby(blocks)['Data'].cumsum().mask(m)
3.02 ms ± 172 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
