event modifier breaks if handler is undefined #9865
Comments
FYI you should just do |
Totally - My issue came from the undefined template ref case. The reproduction given was just easier to show by setting directly to undefined - which obviously makes no sense :) Thanks so much for the quick fix @yyx990803 |
Quick question - I just updated my vue version and I'm still seeing the issue (even though I can see it resolved in the playground). Is that because the code is compiler related and I need to wait for @vitejs/plugin-vue to update to the latest version? Thanks so much! |
Vue version
3.3.12

Steps to reproduce
Use an event modifier (like .prevent on a click event that has an undefined handler - for example
@click.prevent="undefined"
While that may seem silly, something like
@click.prevent="myModalRef?.open()"
is totally reasonable and can result in the same thing...What is expected?
no crash. Probably @click.prevent should still prevent default behaviour...
What is actually happening?
page crashes, with error Cannot read properties of undefined (reading '_withMods')

Any additional comments?
PS - the new issue wizard thing broke.. I got the "Issue Preview" screen, but then it just kept kicking me back to the native "new issue" button on github.
