Deactivating a Vue custom filter when hovering over it

I'm trying to figure out how to disable a truncate filter when hovering over an element using VueJS 2. Here's the part of my template that includes the filter:

<div class="eng" @mouseover="showAll">{{ word.english | truncate }}</div>

And here is the truncate filter function itself:

filters: {
    truncate: function(value) {
      let length = 50;
      if (value.length <= length) {
        return value;
      } else {
        return value.substring(0, length) + '...';
      }
    }
 },

Is there a way to disable the filter upon mouseover so that the text is not truncated anymore? Thank you!

Edit: I thought about removing the filter in the showAll() function. I've tried a few different approaches like:

showAll(){
  console.log('being mousedover');
  this.truncate = false
},

and:

showAll(){
  console.log('being mousedover');
  !this.truncate
}

but I am confused about where to go from here...

Answer №1

Include a Boolean data property called showAll and utilize template tags to decide which version of the variable word.english should be displayed using the v-if and v-else directives:

<div class="eng" @mouseover="showAll = true">
  <template v-if="showAll">{{ word.english }}</template>
  <template v-else>{{ word.english | truncate }}</template>
</div>

To efficiently manage this situation, it is recommended to use a boolean flag and filter a computed property based on whether the flag exists or not. This method allows you to store the value in cache, requiring only one element with a single conditional watcher instead of two.

HTML

<div class="eng" @mouseover="showAll = true" @mouseout="showAll = false">
  {{getWord}}
</div>

JS

export default {
    data() {
        return {
            showAll: false,
            word: {}
        }
    },
    computed: {
        getWord: function () {
            if (this.showAll) return this.word.english

            let value = this.word.english;
            let length = 50;
            if (value.length <= length) {
                return value;
            } else {
                return value.substring(0, length) + '...';
            }
        }
    }
}

This code is expected to function as intended.

      shouldLimitText: true
    }
},
methods: {
    displayFullText() {
        this.shouldLimitText = false
    }
},
filters:{
    limitText(value) {
        let maxLength = 50;
        if (value.length <= maxLength || !this.shouldLimitText) {
            return value;

        else {
            return value.substring(0, maxLength) + '...';
