使用 reactjs 禁用刷新

Question

anybody knows how to disable refresh. the following does not seem to work.

window.addEventListener("beforeunload", () => { 
    return false; 
});

Answer 1

Probably the best thing you can do (with respect to you wanting to prevent a user from accidentally leaving the voice call) is to show them a message they have to confirm before they leave. Try this:

window.onbeforeunload = ()=>"If you leave this page, you'll also leave the call";

Maybe you can also do that in the addListener syntax you already tried (simply return a string instead of false and change onunload to onbeforeunload).

Answer 2

这是在components类中通过shouldComponentUpdate函数完成的，在use中通过输入参数实现，虽然可以通过rect.memo和纯组件来控制，使用回调和使用memo
