What is the process for incorporating a custom attribute into an element with Vue directives?

One of the challenges I'm facing is dealing with a custom attribute called my-custom-attribute. This attribute contains the ID for the element that needs to have the attribute added or removed based on a boolean value.

Although I've implemented a solution in JavaScript that works well, I'm curious if there's a way to achieve this using Vue.js directives instead?

<div my-custom-attribute="my_element">
...
</div>

Here is the current JavaScript implementation:

const el = document.getElementById("some_id");
if(my_bool) {
   el.setAttribute("my-custom-attribute", "#my-element");
} else {
   el.removeAttribute("my-custom-attribute")
}

Answer №1

If you want to make a directive global, take a look at this example below. It gives you access to three lifecycle hooks to manage the behavior. Check out the instructions and try implementing it. If you encounter any issues with your implementation, feel free to ask for help by starting a new thread.

https://v2.vuejs.org/v2/guide/custom-directive.html

Vue.directive('my-custom-directive', {
  // When the bound element is inserted into the DOM...
  inserted: function (el) {
    // Focus the element
    el.focus()
  }
})
