Having trouble retrieving the textContent from a blink element and modifying it. Interestingly, when attempting the same process with a tag or div tag, it works without any issues.
<b-link
:ref="index"
v-b-toggle="`${index}`"
@click="changeText(index)"
>View More</b-link>
changeText(index) {
console.log(this.$refs[index][0].textContent); // undefined
}
I learned a valuable lesson from the vue js test cases on how to tackle this issue. Usually, this method does the trick.
console.log(this.$refs[index][0].textContent);
However, when dealing with bootstrap-vue components which return Vue components, we have to utilize $el to access their properties.
console.log(this.$refs[index][0].$el.textContent);
The contrast between a <div /> and <b-link /> lies in their nature - the former being a standard HTML tag, while the latter is a component that offers a level of abstraction. If you wish to delve deeper into this concept, I suggest exploring native web components alongside their corresponding Vue equivalents.
To modify the content within your <b-link />, it is essential to leverage Vue's reactivity feature:
let buttonText = 'View More';
<b-link
:ref="index"
v-b-toggle="`${index}`"
@click="changeText(index)"
>{{ buttonText }}</b-link>
changeText(index) {
console.log(viewMore); // undefined
viewMore = 'View Less';
}
