我需要找到当前正在构建的网站的加载时间。我已经在本地托管了该网站。如何使用python或javascript找到其加载时间?我尝试了以下代码,但我认为这是为了响应时间。
from time import time
from urllib.request import urlopen
stream = urlopen('https://01c92730.ngrok.io/index.html')
cream = urlopen('https://01c92730.ngrok.io/Webpage.html')
start_time = time()
output = stream.read()
end_time = time()
stream.close()
print(round(end_time-start_time, 3))
start = time()
output = cream.read()
end = time()
cream.close()
print(round(end-start, 3))`
答案 0 :(得分:0)
只需将var start = Date.now()放在页面的开头,将(Date.now()-start)放在页面的末尾即可获取加载时间。 >
在没有加载库的情况下进行1#情况
<doctype html>
<html>
<head>
<script type="text/javascript">
var start = Date.now();
</script>
</head>
<body>
<script type="text/javascript">
document.write("Page load time " + (Date.now() - start) + " milliseconds");
</script>
</body>
</html>
输出:页面加载时间0毫秒(有时1毫秒)
案例2#加载jquery库
<doctype html>
<html>
<head>
<script type="text/javascript">
var start = Date.now();
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
document.write("Page load time " + (Date.now() - start) + " milliseconds");
</script>
</body>
</html>
输出:页面加载时间为24毫秒(有时为22,23)
