我有一个表格，让游客输入入住日期和酒店名称的固定值。
这是html代码，它有一个表单和一个由Contact Form 7生成的模态表单（最新版本带有<form> ... </form>标签：

<form name="request_to_book" id="request_to_book" class="form form-small">
 <div class="form-group">
…
    <div class="row">
        <div class="col col-check-in relative s6">
                        <input type="text" name="check_in" value="01 4, 2023" readonly="" class="form-control check_in " placeholder="m j, Y">
            <i class="fa fa-calendar field-icon"></i>
        </div>
    </div>
…
     <div class="row">
            <div class="col s12">
                <input type="hidden" id="hotel_title" name="hotel_title" value="Hilton Osaka Hotel" readonly="">
            </div>
      </div>
                <div class="pl25 pr25 pb20">
                <a class="waves-effect waves-light btn btn-success btn-full btn-medium bold" href="#modal-contact-form">
                    Request to book                </a>
       </div>
        <div id="modal-contact-form" class="modal" data-created_overlay="true">
                <div class="modal-title">
                    <h4 class="bold">Request to book</h4>
                    <a href="javascript:void(0);" class=" modal-action modal-close waves-effect waves-light btn-flat"><h3>Close</h3></a>
                </div>
                <div class="modal-content">
                    <div role="form" class="wpcf7" id="wpcf7-f1420-p62-o1" lang="en-US" dir="ltr">

<p><label> Check-in date (required)<br>
    <span class="wpcf7-form-control-wrap" data-name="check_in"><input type="text" name="check_in" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" aria-required="true" aria-invalid="false"></span> </label></p>

            </div>
</form>
<a href="javascript:void(0);" class="close-form-book"><i class="flaticon-error"></i></a>

我只想将表单的数据复制到模态表单中：

<script>
jQuery(document).ready(function() {
    jQuery('#request_to_book').change(function() {
        selected_value = jQuery("input[name='hotel_title']").val();
//        alert(selected_value);
        jQuery("#modal-contact-form input[name='hotel_title']").val( selected_value );

        selected_value = jQuery("input[name='check_in’]”).val();
//        alert(selected_value);
        jQuery(".modal-contact-form input[name='check_in']").val( selected_value );
    } );
} );
</script>

获取值的工作很完美，警报确认了这一点。但是我无法在模态联系表单中设置"check_in"的值。
澄清：
1.选择的值= jQuery（"输入[名称='酒店名称']"）. val（）;给出了酒店名称，用这个html代码给出了"Hilton Osaka Hotel"

1. jQuery（"#模态联系人表单输入[名称='酒店名称']"）. val（选定值）;看起来什么也没做，但是它应该把name ="hotel_title"的input-tag设置为"Hilton Osaka Hotel"，所以它看起来没有找到input-tag。这是我的问题。
   有人能帮帮我吗？我做错了什么。
