How can the name of an element be passed as an argument to a function called by that element within a Vue component?

Question

How can the name of an element be passed as an argument to a function called by that element within a Vue component?

I'm currently developing an interactive SVG map inspired by the one found on the CDC page. In my SVG map component, I have implemented multiple path elements that each contain a unique name attribute representing the corresponding state. Additionally, I have integrated a bound class function that I aim to compute for each state as shown below:

<template>
  <svg>
    <path name="New York" :class="computeClass" />
    <path name="California" :class="computeClass" />
    <!-- etc -->
  </svg>
</template>

While this might be a simple query, I am wondering if there is a way to pass the name attribute of the element as a parameter into the computeClass() function it invokes. Perhaps something like:

<path name="New York" :class="computeClass(this.name)" />

Your insights are greatly appreciated!

Answer №1

When passing parameters to a function, it's best to use a method instead of a computed property. Here's an example:

<path name="New York" :class="getPathClass(name)" />

Remember: avoid using this in a template.

...
methods: {
  getPathClass(pathName) {

  }
}

Incorrect. Computed properties function independently without receiving any parameters. If you're looking for a function that can take parameters, consider using methods:

methods: {
  getClasses: (name) => {
    // perform operations with the provided name
  }
}

Another approach is to create a computed property that returns an object containing all necessary data. For instance, if this.name could be aaa, bbb and ccc, you could have the computeClass property return an object like this:

computed: {
  computeClass: () => {
    // perform operations here 
    return {
      aaa: ...,
      bbb: ...,
      ccc: ...
    }
  }
}
