javascript - php javascript - 添加删除动态表单(带有日期选择器输入)

Question

我使用一些代码来克隆表单元素，但我不知道它如何与日期选择器一起使用。

有人可以更新我可以通过输入可以克隆的内容来使用日期选择器的代码吗？使用查询用户界面？

//define template
var template = $('#sections .section:first').clone();

//define counter
var sectionsCount = 1;

//add new section
$('body').on('click', '.addsection', function() {

    //increment
    sectionsCount++;

    //loop through each input
    var section = template.clone().find(':input').each(function(){

        //set id to store the updated section number
        var newId = this.id + sectionsCount;

        //update for label
        $(this).prev().attr('for', newId);

        //update id
        this.id = newId;

    }).end()

    //inject new section
    .appendTo('#sections');
    return false;
});

//remove section
$('#sections').on('click', '.remove', function() {
    //fade out section
    $(this).parent().fadeOut(300, function(){
        //remove parent element (main section)
        $(this).parent().parent().empty();
        return false;
    });
    return false;
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
				
			<div id="sections">
  <div class="section">
    <fieldset>
        <legend>test form - <a href="#" class='button red remove'>delete</a></legend>
        <p>
            <label for="number1">number1:</label>
            <input type="text" name="number1[]"/>
        </p>
		
		<p>
<label for="number2">number2:</label>
            <input type="text" name="number2[]"/>
        </p>
		
		<p>
            <label for="selcet1">selcet1:</label>
 	<select name="select1[]" required>
		<option value="1" >1</option>
    <option value="2" >2</option>
		</select>
        </p>

        <p>
<label for="selcet2">selcet2:</label>
        <select name="selcet2[]" required>
			<option value="1" >1</option>
      <option value="2" >2</option>
			</select>
        </p>


		<p>
<label for="date">Date:</label>
 <input type="text" name="date[]" required /> 
        </p>
		<p>
            <label for="text">text:</label>
<textarea rows=3 type="text" name="text[]" > </textarea>
        </p>

						
    </fieldset>
 
  </div>
</div>

							<a href="#" class='addsection'>add form</a>

我不知道如何添加日期选择器 //输入 type="text"name="date[]"必需//我可以克隆和使用。

请有人帮我看看它是否有效？

JqueryUI解决方案

//define template
var template = $('#sections .section:first').clone();

//define counter
var sectionsCount = 1;

//add new section
$('body').on('click', '.addsection', function() {

    //increment
    sectionsCount++;

    //loop through each input
    var section = template.clone().find(':input').each(function(){

        //set id to store the updated section number
        var newId = this.id + sectionsCount;

        //update for label
        $(this).prev().attr('for', newId);

        //update id - THIS CAUSES JqueryUI Datepicker to bug, also you shouldn't use numerical only IDs
        //this.id = newId;

    }).end()

    //inject new section
    .appendTo('#sections');
    //initialize datePicker on last name=date[] element in HTML DOM
    $("input[name='date[]']").last().datepicker();
    return false;
});
//init original datePicker in HTML DOM
$("input[name='date[]']").last().datepicker();
//remove section
$('#sections').on('click', '.remove', function() {
    //fade out section
    $(this).parent().fadeOut(300, function(){
        //remove parent element (main section)
        $(this).parent().parent().empty();
        return false;
    });
    return false;
});
