In the tutorial, JavaSampleApproach will show you how to build an web application with Html5 DateTime + Jquery Ajax + SpringBoot @JsonFormat.

– Html 5
– JQuery Ajax
– Bootstrap
– Spring Boot – 1.5.7.RELEASE

II. Html5 DateTime + Ajax Jquery + SpringBoot

For working with time input, Html5 support a set of new Input Types:

date
datetime-local
time
week

To bind data from Html5 date input with JQuery, we use new Date():


    $("#taskForm").submit(function(event) {
        // Prevent the form from submitting via the browser.
        event.preventDefault();
        
        // get data from submit form
        var formTask = {
                taskName : $("#taskName").val(),
                startTime : new Date($("#startTime").val()),
                endTime : new Date($("#endTime").val())
        }

To display Date object with customized format, we can use some Date methods as below code


function timeFormat(date){
    if(date instanceof Date){
        var isoDate = date.getFullYear() + '-' + (date.getMonth() + 1) + '-' + date.getDate();
        var time = date.toLocaleString('en-US', { hour: 'numeric',minute:'numeric', hour12: true });
        return isoDate + ' @ ' + time;  
    }else{
        return "";
    }
}

When exchange data between client to server, Json format is used by JSON.stringify(), and Date objects will be converted to String type with UTC standard format.
