我有一个输入框,您可以输入项目,提交项目并使用自己的删除按钮创建一个框以将其删除。问题是,在删除多个框后,然后在输入中输入新内容后,所有以前删除的项目都会重新加载,包括新项目。 如何防止重新装入已移除的盒子?重新加载已删除的列表项目

这是我的HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Shopping List Example</title>
<link rel="stylesheet" type="text/css" href="css-list.css">
</head>
<div id="centerPanel">
<form class="my-list-form">
<input type="text" class="input" name="add-input" id="add-input">
<button class="add-button" id="submitBtn">Add</button>
</form>
<ul class="my-list-ul"></ul>
</div>
<script src="https://code.jquery.com/jquery-2.2.3.min.js"></script>
<script src="js-list.js"></script>
</html>
JS:
var state = {items:[]};
var addItem = function(state, item)
{
state.items.push(item);
}
var displayItem = function(state, element){
var htmlItems = state.items.map(function(item){
return '<li class="box">' + item + '</br><button class="divBtns" id="deleteBtn">Delete</button>' + '</li>';
});
element.html(htmlItems);
}
//After deleting items, this button again loads all items that have been created since
//the page loaded up, including the new item.
//Needs to be fixed to not reload the deleted items
$('.my-list-form').submit(function(event){
event.preventDefault();
addItem(state, $('.input').val());
displayItem(state, $('.my-list-ul'));
/* alert(state.items[1]); shows that the items array holds everything that is turned into a div*/
})
$(document).ready(function(e){
$('ul').on('click', '#deleteBtn', function(event){
var rmvButton = $(this).closest('li');
rmvButton.remove();
});
})
CSS:
* {
font-family: sans-serif;
font-weight: normal;
}
#centerPanel {
margin-left: 50px;
margin-top: 50px;
padding-left: 10px;

}
.font-size {

}
#add-input {

button {

}
除了从您创建的,您也需要到''#deleteBtn'改变为一类像我在的jsfiddle做了数组删除我为你创造 – mplungjan
