我在Chrome中遇到onbeforeunload窗口事件弹出窗口的问题。我已经安装了chrome扩展程序。
步骤:
使用url创建打开浏览器活动:
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_onbeforeunload"\
使用选择器创建Click事件:
<webctrl aaname='Click here to go to w3schools.com' tag='A' />
使用选择器创建Click事件:
<ctrl name='Leave site?' role='dialog' /><ctrl name='Leave' role='push button' />
我的问题是第二次点击不起作用。
