什么HTML不显示HTML标签？
什么HTML不显示HTML标签？
提问于 2017-12-05 23:31:59
几天前，我访问了一个网站，无缘无故地试图查看其源代码。令人惊讶的是，它不包含常规的超文本标记语言标记，如h1、h2、p等。
它只包含如下代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<script>
window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;
if (window.PerformanceObserver) {
var observer = new PerformanceObserver(function(list) {
const entries = list.getEntries();
for (var i=0; i<entries.length; i++) {
var entry = entries[i];
// `name` will be either 'first-paint' or 'first-contentful-paint'.
var metricName = entry.name;
var time = Math.round(entry.startTime + entry.duration);
ga('send', {
hitType: 'timing',
timingCategory: 'Performance Metrics',
timingVar: metricName,
timingValue: time,
});
}
});
observer.observe({entryTypes: ['paint']});
}
</script>

</html>这是什么编程语言/技术？它显示了我浏览器上的所有内容，但html标签仍然不可见。知道这是什么吗？

这是你在那里看到的一些直接的Javascript，运行的代码将生成所有必要的客户端标记(这就是为什么查看源代码不显示它们的原因)。
尝试右键单击一个元素，然后使用"Inspect“。这将打开浏览器的开发工具，并显示Javascript正在生成的HTML代码。
