我在 HTML :
中有一个div<div class="form-check form-check-inline">
<div class="input-group">
<label class="form-check-label">
<input class="form-check-input" type="radio" name="Other" id="Other" value="Other">Other
</label>
<input type="text" class="form-control" id="unique" aria-label="Text input with radio button" disabled>
<div class="btn-group" role="group" aria-label="Basic example">
<button type="button" class="btn btn-success ml-2 border rounded-right" id="Add">Add</button>
<button type="button" class="btn btn-success border rounded" id="Remove">Remove</button>
<button type="submit" class="btn btn-primary ml-3 border rounded">Submit</button>
</div>
</div>
</div>
单选按钮旁边&#34;其他&#34;是一个输入允许用户添加更多银行类型以及删除它 这就是我提出的 Jquery :
var AddButton = $('button[id=Add]');
var RemoveButton = $('button[id=Remove]');
var NewBankDiv = $('<div class="form-check form-check-inline"></div>');
var NewBankLabel = $('<label class="form-check-label"></label>');
var AddBank = $('input[id=unique]');
AddButton.click(function () {
event.preventDefault();
NewBankLabel.append(AddBank.val());
NewBankDiv.append(NewBankLabel);
NewBankDiv.show();
});
RemoveButton.click(function () {
NewBankDiv.remove();
});
它无法正常工作。我应该改变什么?

这是它的工作原理
(function($){
var AddButton = $('button[id=Add]');
var RemoveButton = $('button[id=Remove]');
AddButton.click(function (event) {
event.preventDefault();
var NewBankDiv = $('#newBank');
var AddBank = $('input[id=unique]');
var NewBankLabel = '<label class="form-check-label">' + AddBank.val() + '</label>';
NewBankDiv.append(NewBankLabel);
NewBankDiv.show();
});
RemoveButton.click(function () {
$('#newBank label:last-child').remove();
});
})(jQuery);

你错了:
var NewBankDiv = $('<div class="form-check form-check-inline"></div>');
您可以更改为:
var NewBankDiv = $('.form-check-inline');
它会完成。

以下是每次单击“添加”按钮时附加新项目的最小示例,它将删除单击“删除”时添加的最新项目:
HTML:
<div class="container form-check">
<h1> Hey There! </h1>
</div>
<button id="Add">Add</button>
<button id="Remove">Remove</button>
JS:
var divCount = 1;
$('#Add').click(function(){
$('.container').append(generateNewDivHTML(divCount++));
});
$('#Remove').click(function(){
$('.form-check > .appended').last().remove();
});
function generateNewDivHTML(count){
return '<div class="form-check form-check-inline appended" data-ref='+count+'>'+count+'</div>';
}
您可以在此JSFiddle中运行我的示例。
希望这有帮助!
干杯!

我认为这就是你想要的。只要用户在文本框中输入并按添加,您想要添加具有银行类型的新div,并且只要您想删除银行类型,只需在文本框中键入名称,然后单击删除即可删除该特定银行类型。
此外,我在HTMl中添加了一个div <div id='banklabels'></div>
,其中将附加所有银行类型,因为您没有提到要添加所有银行类型的位置。希望这可以帮助你!!
$(document).ready(function() {
$('#Other').change(function() {
if (this.checked)
$('#unique').prop('disabled', false);
else
$('#unique').prop('disabled', true)
});
var AddBank = $('#unique');;
$('#Add').click(function() {
$('#banklabels').append('<div class="form-check form-check-inline ' + AddBank.val() + '"><label class="form-check-label">' + AddBank.val() + '</label></div>')
});
$('#Remove').click(function() {
if (AddBank.val() != '')
$('#banklabels .' + AddBank.val()).remove();
});
});
