Vue: The function "priceFilter" is not defined in this context

function sanitizeInput(event) {
  event.target.value = event.target.value.replace(/[^\d.]/g, "");
  event.target.value = event.target.value.replace(/^\./g, "");
  event.target.value = event.target.value.replace(/\.{2,}/g, ".");
  event.target.value = event.target.value.replace(".", "$#$").replace(/\./g, "").replace("$#$", ".");
  event.target.value = event.target.value.replace(/^(\-)*(\d+)\.(\d\d).*$/, '$1$2.$3');
}

dom.js

To resolve the error message, it is necessary to define priceFilter on the component instance so that it can be used within the template. Functions from modules or global scope are not directly accessible in templates; only properties defined on the Vue instance can be used.

import { priceFilter } from '../../commons/dom'

export default {
  methods: {
    priceFilter
  }
}

To ensure proper formatting, implement the priceFilter function in your JavaScript file (dom.js).

// dom.js
export default {
      priceFilter(e) {
         e.target.value = e.target.value.replace(/[^\d.]/g, "");
         e.target.value = e.target.value.replace(/^\./g, "");
         e.target.value = e.target.value.replace(/\.{2,}/g, ".");
         e.target.value = e.target.value.replace(".", "$#$").replace(/\./g, "").replace("$#$", ".");
         e.target.value = e.target.value.replace(/^(\-)*(\d+)\.(\d\d).*$/, '$1$2.$3');
     }
}

Then, utilize it like this:

import priceFilter from '../../common/dom'
// If using within a Vue instance, place it in the methods object
....
methods: {
   sampleUsage(e) {
      priceFilter(e);
   }
}
