javascript - 将文本输入字段添加到文本框

Question

我正在使用 jquery 将项目从一个文本框移动到另一个文本框。它工作得很好，但我需要在第 2 组中的每个选项旁边添加一个文本输入值字段。

这是一个例子:

这可能吗？

<script>
$(document).ready(function() {
    $('#btnRight').click(function(e) {
        var selectedOpts = $('#lstBox1 option:selected');
        if (selectedOpts.length == 0) {
            alert("Nothing to move.");
            e.preventDefault();
        }

        $('#lstBox2').append($(selectedOpts).clone());
        $(selectedOpts).remove();
        e.preventDefault();
    });

    $('#btnLeft').click(function(e) {
        var selectedOpts = $('#lstBox2 option:selected');
        if (selectedOpts.length == 0) {
            alert("Nothing to move.");
            e.preventDefault();
        }

        $('#lstBox1').append($(selectedOpts).clone());
        $(selectedOpts).remove();
        e.preventDefault();
    });
});
</script>

        <td style='width:160px;'>

您可以使用 jQuery 欺骗此行为。

    $('#btnRight').on('click',function(e) {
        var selectedOpts = $('#lstBox1 option:selected');
        if (selectedOpts.length == 0) {
            alert("Nothing to move.");
            e.preventDefault();
        }
        var li_wrap = $('<li>');
        var label = $("<label>").text(selectedOpts.val());
        label.attr('for',selectedOpts.val());
        var input = $('<input type="text">').attr({id: selectedOpts.val(), name: selectedOpts.val()});
        label.append(input);
        li_wrap.append(label);
        $(selectedOpts).remove();
        $('ul#lstBox2').append(li_wrap);
        e.preventDefault();
    });

    $('ul#lstBox2').on('click', 'li', function(){
        $('#lstBox2 li').removeClass('selected');
        $(this).addClass('selected');
    });
                        
    $('#btnLeft').on('click',function(e) {
        var selectedOpts = $('#lstBox2 li.selected');
        if (!selectedOpts) {
            alert("Nothing to move.");
            e.preventDefault();
        }
        
        $('#lstBox1').append($('<option/>', { 
        value: selectedOpts.find('label').text(),
        text : selectedOpts.find('label').text() 
    }));
        $(selectedOpts).remove();
        e.preventDefault();
    });
