Here is the code:

    alert(e.target.value);
    }
  }

DATA (Json) of button value

array data: small,medium,large

this.buttonvalue= this.item[0].buttonvalue.split(',');

Answer 1

To get value button value you can either bind a :value attribute first like:

<button
  class="button buttonvalue"
  v-for="(p,index) in buttonvalue"
  :key="index"
  @click="webcamSendRequestButton($event)"
  :value="p"
>{{p}}</button>

Then e.target.value will work fine.

Or, if you don't want to add another attribute, then you can simply use:

methods: {
  webcamSendRequestButton(e) {
     console.log(e.target.textContent)
  }
}

instead of using e.target.value.

Or, if the value p is required, then you can simply pass that to click handler like:

@click="webcamSendRequestButton(p)"

and then access it like:

methods: {
  webcamSendRequestButton(buttonvalue) {
     console.log(buttonvalue)
  }
}

Answer 2

If you simply need to pass a value of p, for example then you would write:

@click="webcamSendRequestButton(p)"

then in your method:

  methods: {
    webcamSendRequestButton(val) {
       alert(val);
    }
  }

I am assuming that buttonvalue is some kind of array that you are looping through.

Hope it helps.
