    regex - JavaScript regular expression to check time format - Stack Overflow

    I would like to have a regular expression which clears an HTML field when the input is not correct. I created this one, but instead of clearing the field when it's incorrect, it clears it only when the input is correct.

    onchange="this.value=this.value.replace(/^([01]?[0-9]|2[0-3]):[0-5][0-9]/,'')"

    I've tried to 'reverse' the code, but it didn't succeed so far.

    Reset to default 5 
    onchange="if (!this.value.match(/^([01]?[0-9]|2[0-3]):[0-5][0-9]/)) this.value = '';"

    if(!/^([01]?[0-9]|2[0-3]):[0-5][0-9]/.test(this.value)) this.value="";

    onchange="this.value=
/^([01]?[0-9]|2[0-3]):[0-5][0-9]/.test(this.value) ? this.value : ''"
