In Vue.js, you can utilize one property to access additional properties within the same element

Is it possible to access other properties of the same element using a different property in Vue.js?

For example:

Rather than writing it like this:

<kpi title="some_kpi" v-if="displayed_kpi==='some_kpi'"></kpi>

Is there a way to achieve something like this instead:

<kpi title="some_kpi" v-if="displayed_kpi===title"></kpi>

This would mean accessing the value of the title property within the v-if condition of the same tag. (Clearly, this approach does not work as intended.) Is there a method to accomplish this?

Latest Update:

If you want to access an element's attributes, you can utilize the $refs variable. This is a useful technique for extracting information from nested components as it grants you access to the element's children attribute. (Check out this source)

However, using the ref attribute may not be effective when combined with v-if because if v-if evaluates to false, the entire element will be removed.

Moreover, there could be synchronization issues between the $refs variable and element creation. Explore more about lifecycle hooks.

<button @click="$event => $forceUpdate()">update me</button>
<kpi ref="MyKpi" title="some_kpi">{{ $refs.MyKpi?.title }}</kpi>

This example demonstrates that upon rendering, $refs.MyKpi does not exist since the element has not been rendered yet. However, by forcing a DOM update, you can observe that we gain access to the attributes in the kpi element.

The $refs variable offers flexibility for performing more intricate operations on element attributes.
