Question

我有3列的bootstrap行。每列都有输入。我有按钮“添加行”，添加另一行3列。每个输入值都复制到textarea。但我有问题。我只能从第一行复制值。如何从所有输入中复制值？第二个问题，我如何格式化输出

ROW1 数据-1 数据-2- 数据-3

行2 数据-4- 数据-5- 数据-6

这是你在找什么？

否使新添加的输入也触发我们的keyup，将$("input").on('keyup', function() {更改为$(document).on('keyup', "input", function() {

$('#add').click(function() {
  $('.row.inputs:last').clone().insertAfter(".row.inputs:last");
  $('.row.inputs:last input').val("")
  console.log($(".row.inputs").length)
  if ($(".row.inputs").length == 2){
  $('.row.inputs:last .col-sm-4:last').css("float","left").after('<div><button style="margin-left: 20px" class="removeRow">remove row</button></div>')
  } 
    
});
$(document).on('keyup', "input", function() {
  updateTextarea()
});

$(document).on('click', ".removeText", function() {
  $(this).prev("input").val("")
  updateTextarea()
});

$(document).on('click', ".removeRow", function() {
  $(this).closest(".row").remove()
  updateTextarea()
});

function updateTextarea() {
  var values = "";
  $(".row.inputs").each(function(i) {
    values += "row" + (i + 1) + ": "
    $(this).find("input").each(function(x, e) {
      $(this).next("button").css("display", this.value.length > 0 ? "initial": "none")
      var text = $(this).prev("label").text();
      values += this.value + " " + text;
    })

    values += "\n"
  });
  $("textarea").val(values);
}

textarea {
  height: 200px;
  width: 400px;
}

.removeText{display:none;}

Answer 2

您必须对动态添加的元素使用事件委派。

您应该使用.on()方法绑定点击事件处理程序。

事件委托允许我们将单个事件监听器附加到父元素，将为匹配a的所有后代触发选择器，无论这些后代现在存在还是被添加到将来

详细了解活动委派here.

$('#add').click(function(){
  var anotherRow=$('.row.inputs:eq(0)').clone();
  anotherRow.append('<div class="col-sm-3"><button class="removeText">remove text</button></div>');
  anotherRow.find('input').each(function(){
    $(this).val('');
  });
  anotherRow.insertAfter(".row.inputs:last");
});
$(document).on('keyup',"input",function() {
    var values = "";
    $("input:text").each(function(i) {
        var text=$(this).prev("label").text();
        values +=  (i%3 ==0 ? "\n row"+(i/3)+" " :"") + this.value+ " "+text;
    });
    $("textarea").val(values);
});
$(document).on('click',".removeText",function() {
    $(this).closest('.inputs').remove();
    var values = "";
    $("input:text").each(function(i) {
        var text=$(this).prev("label").text();
        values +=  (i%3 ==0 ? "\n row"+(i/3)+" " :"") + this.value+ " "+text;
    });
    $("textarea").val(values);
});
