  • You need to set the date input as null in your if condition in javascript.

In your javascript file, you need to set the date as null in your if condition. Refer this:-

if (fieldName === 'start-date') {
    let checkstartdate = evt.target.value;
    console.log("checkenddate == "+new Date(checkstartdate));
    if((????Condition) {
    this.startDate = null; <ADD_THIS_LINE>
    ///**Here on UI I want to set the Start date field as Blank**///
    this.template.querySelector('start-date').reset();
    this.showToast("lllllll");
    this.dateValidity = false;
}
else {
      this.startDate = evt.target.value;
}

  • Please check your condition is working properly. The If condition (Line no 4 in js). Try to use console.log to check if it is going inside your if condition.
