Passing boolean values to component attributes in Vue.js

Question

Passing boolean values to component attributes in Vue.js

I am attempting to create a straightforward input component using Vue, where if the condition IsPassword is true, the type will be set to "password," and if it is false, the type will be set to "text."
I suspect there may be a syntax error causing a parsing JavaScript error.

This is a simplified version of my code
App.vue

import InputText from "@/components/InputText.vue";

<template>
Username : <InputText/>
Password : <InputText :isPassword="true">
</template>

InputText.vue

<template>
<input :type="{IsPassword ? 'password':'text'}" value="I am encountering an error here"> 
</template>
<script>
export default {
    props: {
        IsPassword: Boolean
    }
}
</script>

Answer №1

To begin, ensure that the condition is enclosed in curly braces.

Next, the ternary operator should be structured like this:

condition ? action if true : action if false

Therefore, your code should appear as follows:

<input :type="IsPassword ? 'password' : 'text'" value="I am encountering an error here">

It may be necessary to include support for different types of features in the Input Text field.

To ensure a clean separation of concerns, I recommend keeping the logic outside of the templates:

import InputText from "@/components/InputText.vue";

<template>
Username : <InputText/>
Password : <InputText is-password>
</template>

<template>
   <input :type="inputType" > 
</template>

<script>
import {computed} from 'vue';

export default {
    props: {
        IsPassword: Boolean
    },
    setup(props){
       const inputType = computed(() => props.IsPassword ? 'password' : 'text')

      return{
         inputType
      }
    }

}
</script>
