Web URL加载时间在Web视图中如何检查

Question

如何在React原生web视图中查找url的加载时间？

Answer 1

我是这样做的-

1. 我正在记录onLoadStart时间
2. 然后我记录onLoadEnd时间
3. 并得到他们两个之间的差异

<WebView
source={{
uri,
}}
ref={ref => (this.webview = ref)}
style={{ marginTop: 0, flex: 1 }}
onLoadStart={() => {
this.setState({ onLoadStartTime: Date.now() });
}}
onLoadEnd={() => {
var startTime = this.state.onLoadStartTime;
console.log('I am within onLoadEnd start time is, end tme is, time to load web page is', startTime, Date.now(), startTime - Date.now());
}}
/>
