Prevent space input in text fields using VueJS

Question

Prevent space input in text fields using VueJS

In my TextInput.vue component, I have created a div.

<div ts-text-input :ts-text-input-filled="setFilledAttribute && !!value"
:ts-text-input-not-valid="!valueValid">

<input :value="value" @input="setValue" @keyup.enter="enterClicked" :placeholder="placeholder" :title="title">

I want to prevent users from entering spaces inside the input box, similar to a username input field behavior.

I tried using the trim() function, but it doesn't seem to be working. Here's what I did:

In the computed function

    computed: {
  value: function() {
    const {valueGetter, valueGetterOptions} = this,
      getter = this.$store.getters[valueGetter];
      value.trim();
    return valueGetterOptions ? getter(valueGetterOptions) : getter;
  },

Any suggestions on how to achieve this would be appreciated. Thank you. (Apologies for any language mistakes)

Answer №1

If you want to prevent users from adding a white space to your input field, you can use preventDefault(). This function informs the user agent not to take the default action that would normally occur.

<input @keydown.space="(event) => event.preventDefault()">

Alternatively, you can make it even shorter (as suggested by Sovalina):

<input @keydown.space.prevent>

To ensure no empty spaces are allowed during keypress, paste, or drag and drop events for text:

const removeEventSpaces = e => {
  e.preventDefault();
  const left    = e.target.value.substring(0, e.target.selectionStart);
  const right   = e.target.value.substring(e.target.selectionEnd, e.target.value.length);
  const pasted  = (e.dataTransfer || e.clipboardData).getData('text').replace(/ /g, '');
  e.target.value = left + pasted + right;
}

<input @keydown.space.prevent @paste="removeEventSpaces" @drop="removeEventSpaces"/>

I didn't have luck with @keydown.native.space, but @keydown.native.space.prevent did the trick for me.

If you want to ensure that the input is formatted correctly, consider using Regular Expressions

text.replace(/\s/, '')

Another option is to store the data in lowercase format for consistency

text.replace(/\s/, '').toLowerCase()

One approach is to utilize get and set methods

var userInput = ''

export default {
    name: 'yourFromComponent',
    computed: {
        inputValue: {
            get () {
                return userInput
            },
            set (value) {
                userInput = value.replace(/\s/g,'')
            }
        }
    }
}

If you are using vuex, simply update the userInput reference to your store
