In Vue.js, how can I get a keypress event to get the latest version of the input?
In the following code:
https://codepen.io/anon/pen/WYJopq
I monitor key presses and try to clone the input into another input as follows:
[![methods: {
clone: function() {
this.mirror = this.original;
}
}]
But the cloned input is always one keystroke behind:
https://i.stack.imgur.com/y2uCA.gif
How do I update my code so that the cloned input exactly matches the original input?
(Note: I know for this simple example, there's an idiomatic Vue.js way to do things, but I'm specifically interested in doing this via keystroke monitoring)

is there a reason you are using keypress instead of keyup?

With a keyboard, we have three events fired in the following order:
keydown- fired before character inserted
keypress- fired when a character is getting inserted
keyup- fired when character is already inserted
In this scenario, if you need input with updated characters, you should use keyup event which is after the character is inserted into the input.
Having said this, you should probably use @input event as relying on the keyboard means you are not thinking about other ways via which text can be inserted into the input box. For example, copy-paste or using an on-screen keyboard:
<input type="text" v-model="original" @input="clone()" />
