My Vue instance currently includes the following code:
async mounted () {
document.addEventListener('paste', this.onPasteEvent)
},
beforeDestroy () {
document.removeEventListener('paste', this.onPasteEvent)
},
methods: {
onPasteEvent () {
return async (event) => {
try {
const items = event.clipboardData.items
const files = await this.getBase64Files(items)
this.transferedItems = files
this.modal = true
} catch (error) {
this.$toast.error('Unable to detect a file in the clipboard.')
}
}
},
I am facing an issue with destroying the "paste" event when the component is destroyed. Even though I know I need to use the same reference for removeEventListener, it doesn't seem to work in this case. Could it be that the references are not actually the same?
The only workaround I found was moving the onPasteEvent method outside of the Vue instance as a constant. However, this approach restricts my access to the this instance, which is crucial for me. Additionally, passing arguments becomes impossible with this setup as any attempt seems to create a new reference in memory, preventing the event from being properly removed using removeEventListener.
I am struggling to understand how to remove an event in JavaScript. Can someone provide an example or guidance related to the following questions I have encountered but not fully understood:
- How do I maintain the method reference even when parameters are involved?
- How can I successfully remove events while working with Vue instances?
