javascript - 自举时钟选择器动态输入

在下面的引导代码中，我试图实现时钟选择器的动态输入，这里我使用了wrapper.append（）来实现时钟选择器文本框和其他2个文本框，只需单击一个按钮（add）。

<div  style="height:70px;"></div>
    <div class="container-fluid" >
            <form role="form" name="frm" class="col-xs-12" action ="timeslot" method="post"
            onSubmit="return valid2()">

            <div class="form-group">
                    <label for="name" >Slot Name</label>
                    <input type="text" name="slotname" class="form-control col-xs-6" placeholder="Time Slot name" >
             </div>
                <div  style="height:30px;"></div>
             <div class="form-group row">
             <div class="col-xs-6">
                    <label for="name" >Time Slot</label>
                    <input type="text" name="timeslot1" class="form-control col-xs-6" placeholder="Time Slot name" >
             </div>
             <div class="col-xs-6">
                    <label for="name">Slot Available</label>
                    <input type="text" name="slotavailable1" class="form-control" placeholder="Slot available" >
             </div>
             </div>

             <label for="name" >Time</label>
            <div class=" form-group row">

ps:对不起，代码太长了。
感谢@cale椆b帮我写上一篇文章。

最佳答案

我将包括更多的原始问题，只是为了帮助-因为有些事情会让你的生活更容易向前发展。
提示：不需要单独的<script>块，也不需要单独的文档准备功能。
解决方案：为了让时钟选择器处理动态添加的元素，需要在动态添加元素后bind它们。
最有组织的方法是创建一个绑定时钟选择器元素的函数，然后在需要时调用该函数：

// Script tags do not need type="text/javascript", so I've removed
<script>
jQuery(function($) {
    // The original "clockpicker" code is moved to the bottom in a function
    // No need to close and re-open script tags, so I've removed those
    // No need for a new "document ready" function, so I've removed that
    var max_fields      = 15; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID

    var x = 2; //initlal text box count
    $(add_button).click(function(e) { //on add input button click
        e.preventDefault();
        if(x < max_fields) { //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div> <div  style="height:30px;"></div>'+
                '<div class="form-group row">'+
                    '<div class="col-xs-6">'+
                      '<label for="name"+x >Time Slot</label>'+
                      '<input type="text" name="timeslot"+x class="form-control col-xs-6" placeholder="Time Slot name" ></div>'+
                     '<div class="col-xs-6">'+
                        '<label for="name"+x>Slot Available</label>'+
                        '<input type="text" name="slotavailable"+x class="form-control" placeholder="Slot available" >'+
                     '</div>'+
                '</div>'+
                '<label for="name"+x >Time</label>'+
                '<div class=" form-group row">'+
                    '<div class="form-group clockpicker col-xs-6" data-placement="left" data-align="top" data-autoclose="true" >'+
                        '<input type="text" id="start_time"+x name="start_time"+x class="form-control" value="09:30">'+
                         '<span class="form-group-addon">'+
                            '<span class="glyphicon glyphicon-time "></span>'+
                         '</span>'+
                    '</div>'+
                    '<div class="form-group  clockpicker col-xs-6" data-placement="left" data-align="top" data-autoclose="true" >'+
                        '<input type="text" id="end_time"+x name="end_time"+x class="form-control" value="09:30">'+
                        '<span class="form-group-addon">'+
                            '<span class="glyphicon glyphicon-time"></span>'+
                        '</span>'+
                    '</div>'+
                '</div>'+
            '<a href="#" class="remove_field">Remove</a></div>'); //add input box
            // NEW: Bind to the newly added clockpicker element
            bindClockPicker();
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove();
        x--;
    });

    // This function "binds" the clockpicker
    function bindClockPicker() {
        $('.clockpicker').clockpicker({
            placement: 'top',
            align: 'left',
            donetext: 'Done'
        });
    }

    // Last but not least, call this to bind to any existing clockpicker elements
    bindClockPicker();
});
