Why every text shows on img hover when using v-if, v-else, @mouseover and @mouseleave in Vue.js?-CodePudding

I am trying to create a hover effect on images with Vue.js. I wrote the following code, but now as I hover over one of the images, the text shows up over all the images. How can I resolve this problem? I want only the text that belongs to the image I hovered over to appear. Thank you in advance for your help.

Vue template:


<template>
<div class="row partner-body-row">
        <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = true"
            @mouseleave="showText = false"
          >
            <img
              class="hover-img"
              src="img/img-1"
              alt="img-1"
            />
            <span v-if="showText">Text 1</span>
          </div>
        </div>
<div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = true"
            @mouseleave="showText = false"
          >
            <img
              class="hover-img"
              src="img/img-2"
              alt="img-2"
            />
            <span v-if="showText">Text 2</span>
          </div>
        </div>
        <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = true"
            @mouseleave="showText = false"
          >
            <img
              class="hover-img"
              src="img/img-3"
              alt="img-3"
            />
            <span v-if="showText">Text 3</span>
          </div>
        </div>
        
     <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = true"
            @mouseleave="showText = false">
            <img
              class="hover-img"
              src="img/img-4"
              alt="img-4"
            />
            <span v-if="showText">Text 4</span>
          </div>
        </div>
      </div>
</template>

Script:

export default {
  data: () => {
    return {
      showText: false,
    };
  },
};

all the conditions are tied to the same variable, have that variable hold each image's number rather than just true/false.

and ideally this should be done in CSS using :hover

<template>
<div class="row partner-body-row">
        <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = 1"
            @mouseleave="showText = 0"
          >
            <img
              class="hover-img"
              src="img/img-1"
              alt="img-1"
            />
            <span v-if="showText === 1">Text 1</span>
          </div>
        </div>
<div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = 2"
            @mouseleave="showText = 0"
          >
            <img
              class="hover-img"
              src="img/img-2"
              alt="img-2"
            />
            <span v-if="showText === 2">Text 2</span>
          </div>
        </div>
        <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = 3"
            @mouseleave="showText = 0"
          >
            <img
              class="hover-img"
              src="img/img-3"
              alt="img-3"
            />
            <span v-if="showText === 3">Text 3</span>
          </div>
        </div>
        
     <div class="col">
          <div
            class="img-wrapper"
            @mouseover="showText = 4"
            @mouseleave="showText = 0">
            <img
              class="hover-img"
              src="img/img-4"
              alt="img-4"
            />
            <span v-if="showText === 4">Text 4</span>
          </div>
        </div>
      </div>
</template>

export default {
  data: () => {
    return {
      showText: 0,
    };
  },
};

You could just create a component for each Image with tooltip, something like:

Vue.config.productionTip = false;

const Img = {
  name: 'Img',
  props: ['src'],
  data() {
    return { showText: false }
  },
  template: '<div><img @mouseover="showText = true" @mouseleave="showText = false":src="src" /><span v-if="showText">Tooltip</span></div>',
};

const App = new Vue({
  el: '#root',
  components: { Img },
  template: '<div><Img src="https://via.placeholder.com/150"/><Img src="https://via.placeholder.com/150"/></div>',
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="root"/>
