Steps to reproduce

<template>
  <div>
    <el-slider @input="handleSliderInput" :value="value"/>
    <button type="button" @click="buttonClick">Click me</button>
  </div>
</template>
<script>

export default {
  name: "App",
  data() {
    return {
      value: 1
    };
  },
  components: {
    // HelloWorld
    "el-slider": Slider
  },
  methods: {
    handleSliderInput(v) {
      console.log(arguments);
      this.value = v;
    },
    buttonClick() {
      console.log("button click");
      this.value  ;
    }
  }
};
</script>

What is Expected?

There needs to be a value, passed in handleSliderInput() , that tells whether the input event is generated by change of the value property from JavaScript or manually by mouse.

What is actually happening?

There is no such value that one could get in the input handler method like handleSliderInput() .
