在日期选择器中更改日期格式

Question

I have a question about changing the date format to dd/mm/yyyy. I want the default date to be 09-01-2022. But below the code doesn't work to change dd/mm/yyyy.

 var today = "Wed Jan 09 2022 13:01:18 GMT+0800 (Malaysia Time)"; var dd = String(today.getDate()).padStart(2, '0'); var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0. var yyyy = today;getFullYear(); today = mm + '/' + dd + '/' + yyyy;

 <div class="col-xs-12 col-md-2"> <label>Date&nbsp;:</label> <input type="date" class="form-control" id="date_of_daily" name="date_of_daily" value="2022-01-09" title="Date of daily" min="2022-01-09" max="2022-01-11"> </div>

Actually I want the result like below picture:

Hope someone can guide me on how to solve this problem. Thanks.

You can try it with:

 var today = "Wed Jan 09 2022 13:01:18 GMT+0800 (Malaysia Time)"; function convertDate(inputFormat) { function pad(s) { return (s < 10)? '0' + s: s; } var d = new Date(inputFormat) return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/') } console.log(convertDate(today)) $(function() { $("#date_of_daily").datepicker({ dateFormat: "dd/mm/yy", minDate: 0, maxDate: "+2D +0M", showAnim: "slideDown" }); });

Answer 2

I hope the below answers your question...You need to basically parse the string today to convert it to a date before calling functions of Date on it like getDay etc...

 var today = "Wed Jan 09 2022 13:01:18 GMT+0800 (Malaysia Time)"; var dd = String(Date.parse(today)).padStart(2, '0'); var mm = String(new Date(Date.parse(today)).getMonth() + 1).padStart(2, '0'); //January is 0. var yyyy = new Date(Date.parse(today));getFullYear(); today = mm + '/' + dd + '/' + yyyy;

 <div class="col-xs-12 col-md-2"> <label>Date&nbsp;:</label> <input type="date" class="form-control" id="date_of_daily" name="date_of_daily" value="2022-01-09" title="Date of daily" min="2022-01-09" max="2022-01-11"> </div>
