Using VueJS to apply directives across all matching elements

Question

Using VueJS to apply directives across all matching elements

Is it possible to apply a directive to all input tags programmatically? There are two primary reasons why this is desirable:

Avoiding the need to individually add the directive to each input in the application
Simplifying the process of making changes to the directive for all inputs at a later time by having it centrally located

I have looked through the documentation, but it appears that applying the directive directly to the element is the only method mentioned. Is there any other way to achieve this?

Here is the current code I am working with:

<input type="text" class="form-control input-sm" id="price" v-model="model.doc.price" v-floating-label>

It appears that my brain decided to take a little vacation for a moment there. All I needed was an input element. By customizing this element, I can make changes and have them reflected in all instances where it's used. Instead of relying on the traditional html input tag, I'll opt for using my own custom component.

Just one of those days...

I've chosen to leave my answer here instead of removing it, just in case someone else experiences a similar temporary lapse in concentration down the line ;)

In the words of Evan You:

When you initialize or mount the root instance, that is when Vue.js compilation takes place.

For further information, please refer to https://github.com/vuejs/Discussion/issues/77#issuecomment-60339440

It seems quite unconventional what you are attempting to achieve: utilizing search and replace functionality available in various text editors or IDEs may substantially aid your stated goals.

To apply that directive based on a specific condition, use the following syntax

<input type="text" 
       class="form-control input-sm" 
       id="price" 
       v-model="model.doc.price" 
       :v-floating-label=(condition)>

If the condition is true, then the v-model-float directive will affect your input element.

Update 1: As suggested in the feedback, you can keep the implementation as is, but manage the condition from a centralized location. This allows you to easily disable the directive by changing the condition to false later on.
