Looking to extract a value or id in Alpine JS onclick, I thought this.id or this.value would work but no luck.
Returns
Alpine Expression Error: Can't find variable: id
<button id="myBtn" value="100" x-on:click="alert(this.id);">Save</button>
CodePudding user response：
This might help you.
<button @click="alert($event.target.getAttribute('message'))" message="Hello World">Say Hi</button>
$event.target will give you access to the clicked element.

CodePudding user response：
Pass the Event with $event. Then you can handle it like in vanilaJs.
function hello(e) {
console.log(e.target.getAttribute('id'))
} <script defer src="https://unpkg.com/[email protected]/dist/cdn.min.js"></script>
<button id="myBtn" value="100" @click="hello($event);">Save</button>
