如何在Bootstrap日期選擇器中獲得下個月上個月而不是下一個上一個圖標？

Question

我正在使用引導程序日期選擇器，我想更改下個月和上個月的顯示而不是箭頭。 我已經完成了一些功能，但工作不准確......

 $(document).ready(function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; $('#datepicker').datepicker({ inline: true, todayHighlight: true, }).on('changeDate', function(e) { $('#dt_due').val(e.format('dd/mm/yyyy')); }).on('changeMonth', function(e) { var prevMonth = new Date(e.date).getMonth()-1; console.log(prevMonth); prevMonth > 12 ? prevMonth = 0 : prevMonth; var currMonth = new Date(e.date).getMonth(); console.log(currMonth); $('.pickDate').find('table .prev').html(monthNames[prevMonth]); var nextMonth = new Date(e.date).getMonth() + 1; console.log(nextMonth); nextMonth > 12 ? nextMonth = 0 : nextMonth; $('.pickDate').find('table .next').html(monthNames[nextMonth]); $('#dt_due').val(e.format('dd/mm/yyyy')); }); function getInitMonths() { var prevMonth = new Date().getMonth(); console.log(prevMonth); var currMonth = new Date().getMonth() + 1; console.log(currMonth); console.log(monthNames[currMonth - 1]) $('.pickDate').find('table .prev').html(monthNames[currMonth - 2]); var nextMonth = new Date().getMonth() + 2; console.log(nextMonth); nextMonth > 12 ? nextMonth = 0 : nextMonth; $('.pickDate').find('table .next').html(monthNames[nextMonth]); } getInitMonths(); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.4/css/bootstrap-datepicker.css"> <script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.4/js/bootstrap-datepicker.js"></script> <div id="datepicker" class="pickDate"></div>

我怎樣才能做到這一點？

注意：- 問題出現在月份是 12 月、1 月...

請幫助/建議給我...

Answer 1

您需要在document.ready之外定義getInitMonths()的實現。

這是運行沒有錯誤的JSFiddle 。

 $(document).ready(function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; $('#datepicker').datepicker({ inline: true, todayHighlight: true, }).on('changeDate', function(e) { $('#dt_due').val(e.format('dd/mm/yyyy')); }).on('changeMonth', function(e) { var prevMonth = new Date(e.date).getMonth()-1; console.log(prevMonth); prevMonth > 12 ? prevMonth = 0 : prevMonth; var currMonth = new Date(e.date).getMonth(); console.log(currMonth); $('.pickDate').find('table .prev').html(monthNames[prevMonth]); var nextMonth = new Date(e.date).getMonth() + 1; console.log(nextMonth); nextMonth > 12 ? nextMonth = 0 : nextMonth; $('.pickDate').find('table .next').html(monthNames[nextMonth]); $('#dt_due').val(e.format('dd/mm/yyyy')); }); function getInitMonths() { var prevMonth = new Date().getMonth(); console.log(prevMonth); var currMonth = new Date().getMonth() + 1; console.log(currMonth); console.log(monthNames[currMonth - 1]) $('.pickDate').find('table .prev').html(monthNames[currMonth - 2]); var nextMonth = new Date().getMonth() + 2; console.log(nextMonth); nextMonth > 12 ? nextMonth = 0 : nextMonth; $('.pickDate').find('table .next').html(monthNames[nextMonth]); } getInitMonths(); });

 $(document).ready(function() { var monthMinusOneName = moment().subtract(1, "month").startOf("month").format('MMMM'); var monthPlusOneName = moment().add(1, "month").startOf("month").format('MMMM'); var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; $('#datepicker').datepicker({ inline: true, todayHighlight: true, }).on('changeDate', function(e) { $('#dt_due').val(e.format('dd/mm/yyyy')); }).on('changeMonth', function(e) { var monthMinusOneName = moment(e.date).subtract(1, "month").startOf("month").format('MMMM'); var monthPlusOneName = moment(e.date).add(1, "month").startOf("month").format('MMMM'); $('.pickDate').find('table .prev').html(monthMinusOneName); $('.pickDate').find('table .next').html(monthPlusOneName); }); function onInit() { var monthMinusOneName = moment().subtract(1, "month").startOf("month").format('MMMM'); var monthPlusOneName = moment().add(1, "month").startOf("month").format('MMMM'); $('.pickDate').find('table .prev').html(monthMinusOneName); $('.pickDate').find('table .next').html(monthPlusOneName); } onInit() })

 <script type="text/javascript" src="https://code.jquery.com/jquery-3.4.1.js"></script> <link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.4/css/bootstrap-datepicker.css"> <script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.4/js/bootstrap-datepicker.js"></script> <script src="https://momentjs.com/downloads/moment.min.js"></script> <div id="datepicker" class="pickDate"></div>

注意：- 我為下個月和上個月的名稱添加了時刻 js。
