Modifying the functionality of "use-input" in Vue.js

Currently, I am utilizing vue.js along with typescript to create an input field that allows users to either choose items from a drop-down menu or manually type in their own input. There are various scenarios where custom input might be allowed or where only input from the drop-down menu is permitted (which is pre-defined).

In my exploration, I came across a method called "use-input" that enables me to enable or disable user keyboard input. However, at this point, I can only manage this functionality by placing "use-input" within the

<q-select></q-select>
element or completely removing it. Instead, I wish to have control over the input behavior through a flag like use-input="False". Upon trying this approach, I encountered the following error message:

[Vue warn]: Invalid prop: type check failed for prop "useInput". Expected Boolean, but received a String with the value of "False".

My assumption now is that the "useInput" property should indeed accept a boolean value, but I seem to be missing the correct syntax to make it functional. Additionally, I couldn't locate any documentation pertaining to useInput, so I'm wondering if anyone here has previously dealt with it?

Below is a small snippet of the code which highlights the issue:

<template>
  <q-item
    class="item"
  >
    <div
      class="item-content column"
      style="width: 100%;"
      @click.passive="click"
    >
      <q-select
        use-input="False"
        @input="inputChanged"
      >
  </q-select>
</template>

Answer №1

It is recommended to

:use-input="false" 

By using a colon before your attribute in the template, Vue recognizes that you are inputting JavaScript code. This allows you to add booleans, methods, objects, arrays, etc. If you need to add a string, make sure to wrap it in single quotes like so:

:some-attribute="'some string'"

Additionally, remember that 'true' and 'false' should not be capitalized.

Moreover, you can utilize template literals to combine strings with JavaScript expressions:

:some-attribute="`My name is ${myName}`"
