Question

我是jQuery的新手，现在已经有很长一段时间了解这个问题。

我在输入字段中使用jQuery ui datepicker，单击按钮时动态添加。日期选择器仅适用于输入框的第一个实例。尝试过寻找解决方案，但没有运气。任何帮助将不胜感激。感谢

jQuery代码

$( ".datepicker" ).datepicker({
        inline: true,
        dateFormat: "yy-mm-dd"
    });

Html代码

<div id="newlink">
    <div>
        <table style="border: 1px solid black;">
            <tr>

您需要在您创建的新输入元素中设置datePicker，但是如何复制具有所需日期选择器的输入，从新元素中删除类hasDatePicker。请尝试下面的代码。

HTML

<div id="newlink">
    <div>
        <table style="border:1px solid black;">
            <tr>
                <th>Date:</td>
                    <td>
                        <input type="text" name="linkurl[]" id="Editbox18" class="datepicker" style="width:147px;height:23px;z-index:2; color:black" autocomplete="off">

Answer 2

据我记得，当使用多个日期选择器时，他们需要输入的唯一ID。因此，如果您要添加新内容，首先需要独特的ID。文档就绪是在加载所有文档元素时发生的单个事件。所以你需要绑定其他东西。 e.g。

HTML

<div id="linkscontainer">
<div id="newlink" class="linkbox">
    <div style="border:1px solid black;"> <span>Date:</span>
        <span><input type="text" name="newdate[]" value="" id="dates" class="date" /><span>


    <div>Remark:</div>


<textarea name="linkdesc[]" size="1" id="Editbox19" style="width:550px;height:45px;z-index:2; color:black" autocomplete="off"></textarea>

    </span></span></div> 
    <input  type="button" class="delete" name="delete" id="delete" value="delete" style="width: 80px; height: 24px; z-index: 136; color: black;">    
    </div>
    </div>

<input  type="button" id="addnew" name="linkdesc[]" value="Add More" style="width: 80px; height: 24px; z-index: 136; color: black;">

jquery的

$(document).ready(function(){

var container= $('#newlink').html(); // container to add
var ids=1; //id numbers for add. datepickers

$('#addnew').click(function() {
     $('#linkscontainer').append(container); // add container
    $('.date:last').attr('id', ids);// each datepicker must have a unique id. 
    $('.delete:last').attr('id', 'f'+ids);// each deletebutton must have a unique id. 
    ids++; // increase the id numbers

});

}）;

$(document).on('focus',".date", function(){ //bind to all instances of class "date". 
   $(this).datepicker();
});

小提琴：

编辑：

删除按钮需要以相同的方式完成：

$(document).on('focus',".delete", function(){ //bind to all instances of class "date". 
 $(this).parent().remove(); 
});
