我有一种待办事项列表,在单击“添加”按钮时添加元素。有两条默认行。 add 函数效果很好,这是原始代码
$(function() {
$(".container").on('input', 'input[type=text]', function(event) {
var i = $(this).closest(".flex-row").index();
var v = (i == 0) ? $(this).val() : "|" + $(this).val();
$("#custom_wrapper .output").eq(i).html(v);
});
$('.add').click(function() {
var count = $("input").length;
count++;
var row = $("<div>", {
class: "flex-row"
}).insertBefore(this);
$("<label>").appendTo(row);
$("<input>", {
type: "text",
class: "input",
placeholder: "custom text " + count,
tabindex: count
}).appendTo($("label", row));
$("<button>", {
class: "remove"
}).html("-").appendTo(row);
$("<span>", {
class: "output"
}).insertAfter($("#custom_wrapper .output:last"));
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.1/jquery.min.js"></script>
<div class="container">
<div class="wrapper">
<article>
<section>
<div class="flex-row">
<label><input class="input" type="text" name="" placeholder="custom text" tabindex="1" /></label><button class="remove">-</button>
</div>
<div class="flex-row">
<label><input class="input" type="text" name="" placeholder="custom text 2" tabindex="2"></label><button class="remove">-</button>
</div>
<button class="add">+</button>
<div class="flex-row">
<div>customText{{[<span id="custom_wrapper"><span class="output"></span><span class="output"></span></span>]}}</div>
</div>

现在,我添加了一个按钮来删除线条。这就是它被卡住的地方。
例如:我添加两行,总共有 4 行。例如,每一行都有一个字母。 (a,b,c,d) 我删除“b,c,d”并保留“a”;当我添加更多内容时,添加的文本将被插入到“a”之前,而它应该在“a”之后。如果我继续添加更多内容,文本将替换现有文本,而不是被添加。
此外,我希望在我的 span.output 中,第一个文本之前永远没有管道。
有人知道问题出在哪里吗?
这是我更新的代码:
$(function() {
$(".container").on('input', 'input[type=text]', function(event) {
var i = $(this).closest(".flex-row").index();
var v = (i == 0) ? $(this).val() : "|" + $(this).val();
$("#custom_wrapper .output").eq(i).html(v);
});
$('.add').click(function() {
var count = $("input").length;
count++;
var row = $("<div>", {
class: "flex-row"
}).insertBefore(this);
$("<label>").appendTo(row);
$("<input>", {
type: "text",
class: "input",
id: "custom-text-" + count,
placeholder: "custom text " + count,
tabindex: count
}).appendTo($("label", row));
$("<button>", {
class: "remove"
}).html("-").appendTo(row);
$("<span>", {
class: "output",
dataid: "custom-text-" + count
}).insertAfter($("#custom_wrapper .output:last"));
});
$('body').on('click', '.remove', function() {
$(this).parent('.flex-row').remove();
var j = $(this).parent().find('.input').attr("id");
$('#custom_wrapper .output[dataid="' + j + '"').empty();
})
})

这有帮助吗?
$(function() {
let nextInputId = 3;
$(".container").on('input', 'input[type=text]', function(event) {
const i = $(this).closest(".flex-row").index();
const v = ((i == 0) ? "" : "|") + $(this).val();
$("#custom_wrapper .output").eq(i).html(v);
});
$('.add').click(function() {
const count = $("input").length;
const row = $("<div>", {
class: "flex-row"
}).insertBefore(this);
$("<label>").appendTo(row);
$("<input>", {
type: "text",
class: "input",
id: "custom-text-" + nextInputId,
placeholder: "custom text " + (count + 1),
tabindex: (count + 1)
}).appendTo($("label", row));
$("<button>", {
class: "remove"
}).html("-").appendTo(row);
$("<span>", {
class: "output",
dataid: "custom-text-" + nextInputId
}).insertAfter($("#custom_wrapper .output:last"));
nextInputId++;
});
$('body').on('click', '.remove', function() {
const i = $(this).closest(".flex-row").index();
$("#custom_wrapper .output").eq(i).remove();
$(this).parent('.flex-row').remove();
})
});
