javascript - 在克隆字段上添加删除按钮

大家好，我需要帮助在克隆发生后添加“删除”按钮。 “删除”按钮应删除克隆的字段。任何建议将不胜感激。 Bootply 版本 - http://www.bootply.com/LiqkgWUFF6

提前致谢。

var template = $('#line_1').clone();

$('#cloneButton').click(function () {
    var rowId = $('.row').length + 1;
    var klon = template.clone();          
    klon.attr('id', 'line_' + rowId)
        .insertAfter($('.row').last())
        .find('option')
        .each(function () {
            $(this).attr('id', $(this).attr('id').replace(/_(\d*)$/, "_"+rowId));
        })                   
});

试试这个:

var template = $('#line_1').clone();

$('#cloneButton').click(function () {
    var rowId = $('.row').length + 1;
    var klon = template.clone();   
    console.log(klon)       
    klon.attr('id', 'line_' + rowId)
        .insertAfter($('.row').last())
        .find('option')
        .each(function () {
            $(this).attr('id', $(this).attr('id').replace(/_(\d*)$/, "_"+rowId));
        })    

        $("#line_" + rowId).append("<a href='javascript:void(0);' class='remove'>delete</a>")               
});

$(document).on("click", ".remove", function() {
  $(this).closest(".row").remove();
});
