解决方案
问题是当您最初绑定事件时,新的字段不存在。
通过使用选择器 .input_date
,它应该以动态形式将事件附加到新元素。
$(function(){
$ ('body')。on('click','。input_date',function(){
$(this).datepicker('destroy')。datepicker({showOn:'focus'})focus );
});
});
更好的方法:
您应该在创建元素时初始化字段的日期戳。
$ function(){
$('。input_date')。datepicker();
});
函数createNewDatepickerInput(){
var $ newInput = $('< input type =textname =date123class =input_date/>');
$ newInput.appendTo(form)。datepicker();
}
I have a problem. jQuery Datepicker does not work in a dynamic form, so you can't pick a date. Here is my demo link http://gestionale.odoyabooks.com/sum.php.
JavaScript:
<script>
$(document).ready(function() {
$('.input_date').on('click', function() {
$(this).datepicker('destroy').datepicker({showOn:'focus'}).focus();
});
});
</script>
HTML:
<form action="" method="POST">
<div class="yes">
<div id="cost1" class="clonedCost" style="display: inline;">
<table border="0">
<tr>
<td><label class="date" for="date">Date</label></td>
</tr>
<tr>
<td><input class="input_date" id="date" type="text" name="date[]" /></td>
</tr>
</table>
</div>
<div id="addDelButtons_cost"><input type="button" id="btnAdd" value=""> <input type="button" id="btnDel" value=""></div>
</div>
</form>
解决方案
The problem is that when you bind the event initially, the new field doesn't exist.
By applying the on click to the body, with the selector .input_date
, it should attach the event to the new element in the dynamic form.
$(function() {
$('body').on('click','.input_date', function() {
$(this).datepicker('destroy').datepicker({showOn:'focus'}).focus();
});
});
A better way:
You should initialize the datepicker for the field when you create the element.
$(function() {
$('.input_date').datepicker();
});
function createNewDatepickerInput() {
var $newInput = $('<input type="text" name="date123" class="input_date" />');
$newInput.appendTo("form").datepicker();
}
