    //focus event
    document.querySelector('jb-time-input').addEventListener('focus',()=>{});
    document.querySelector('jb-time-input').addEventListener('blur',()=>{});

set value

to set value of time input you have 2 way:

• by html as a attribute:

<jb-time-input value="14:34:63">

• by javascript

    document.querySelector('jb-date-input').value = "01:11:12";

validation

jb-time-input use jb-validation inside to handle validation so for more information you can read it's documentation.

jb time input will check validation automatically and show error on user blur the input and hide error on user type and blur to use this feature you just have to set validation list of component.

document.querySelector('jb-time-input').validationList = [
    //regex validator
    {
      validator: /^[1][1234].*$/g,
      message:"hour  must be between 11 and 14"
    },
    //callback function validator
    {
      validator:({displayValue,value,valueObject})=>{
        //display value is the value user see
        //value is the value developer get by dom.value
        //valueObject is the {hour:number,minute:number,second:number} object contain inputted value in number
        if(valueObject.minute<30){
          return false;
        }
        return true;
      },
      message:'minute must be 30 to 60'
    }
  ]

you can trigger validation manually by calling checkValidity function. for example you can call it when submit button clicked and check if value is valid or not.

    // if you set showError false you can get validation result but component wont show error to user by itself its good when you want show error in your own way
    const showError = true;
    const validationResult =  document.querySelector('jb-time-input').validation.checkValidity(showError);
    if(validationResult.isAllValid){
        alert('all validation are passed')
    }else{
        alert('validation error!');
    }

you can also get validation result of your time input by following way:

    document.querySelector('jb-time-input').validation.resultSummary
