VueJS - disable space in input text
You can directly prevent that the user adds a white space to your input field. preventDefault() tells the user agent that the default action should not be taken as it normally would be.
<input @keydown.space="(event) => event.preventDefault()">Or to make it even shorter (as Sovalina pointed out):
<input @keydown.space.prevent>
To prevent spaces on all input events - keypress, paste or drag and drop 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"/>
