事件中使用以下if语句,因此每秒调用3-4次。虽然这种方法运行得很好,但我发现它没有吸引力,我希望得到一些提示,使它成为一个更简单的解决方案而不重复。
from installtools import setup
scripts = ['create_database.py', 'run_migrations.py']
setup("Shelob", "requirements.txt", scripts)

您可以使用开关语句,但这似乎只是计算适当的舍入值。由于似乎总是需要ajax请求,因此在“监视”逻辑之后调用它:
var percent_watched = 67;
if (percent_watched >= 100) {
console.log('video ended');
} else {
console.log(Math.floor(percent_watched/10) + '0% watched')
}
// Ajax Request

您正在检查而我= =号码?你确定这是条件,当你在循环中递增i时。 (这似乎不是有效的逻辑)
怎么样:
var i = 0;
while (i <= percent_watched) {
console.log(percent_watched + '% watched');
i += 10;
// Ajax Request
}
