[英]Jquery Cloned Html Divs Don't Function
视频我做到了,所以当你点击一个按钮时,用户可以复制笔记 div,但复制的不是 div 不是 function 作为原始它不可拖动,而且当我改变复制笔记的颜色时,它也会改变原始笔记颜色有没有办法可以解决这个问题并使其复制的笔记与原始笔记完全一样?
我使用 jquery 使带有 id 注释的 div 可拖动并且还克隆
$('#note').draggable({
handle: "#headeR"
});
//this will duplicate the note container
function dup(){
$(function(){
$('#note').clone().appendTo('#notecopy');
});
我正在复制的 div
<!-- my note area container-->
<div class="NoteSection" id="note">
<!--text container-->
<!--text header with colors-->
<div id="headeR">
<button id="color#1" class="BtnColor1" onclick="greennote()"></button>
<!--buttons to change color-->
<button id="color#1" class="BtnColor2" onclick="bluecolor()"></button>
<button id="color#1" class="BtnColor3" onclick="redcolor()"></button>
<button id="color#1" class="BtnColor4" onclick="purplecolor()"></button>
<button class="BtnColor5" onclick="deleteR()"><span class="black"></span><span
class="material-symbols-outlined">Delete</span></button>
</div>
<!--text header with colors-->
<!--text area-->
<div class="textspot" id="NOTEE">
<textarea id="notepage" name="notes" row="20" cols="20" maxlength="67"></textarea>
</div>
<!--text area-->
</div>

您需要了解 ID 标签必须是唯一的。 每次制作克隆时,您都在重复使用它们,这就是为什么这对您不起作用的部分原因。
我在下面展示了几种解决此问题和优化代码的方法。 请注意,我在 javascript 中根本不使用 ID。 我在 HTML 中留下了参考资料,因为我不想清理所有多余的东西……只显示 JS。 请注意我如何使用element.closest(ref)来查找容器,以便我知道哪些按钮会影响哪个记事本。 我还展示了如何使用相同的逻辑进行删除 function
$('.NoteSection').draggable({ handle: ".headeR" }); // get the 'master' refrerence so we can use it to make copies easily let masterCopy = $('.NoteSection').first() //this will duplicate the note container function dup() { masterCopy.clone().appendTo('#notecopy'); } // changes notes colors let colors = { green: '#C2EA92', blue: "#92EADD", red: "#EA92A5", purple: "#EA92E9" } function deleteR(el) { el.closest('.NoteSection').remove() } function changeColor(el, color) { el.closest('.NoteSection').querySelector(".notepage").style.backgroundColor = colors[color]; }
.NoteSection { font-family: 'Combo', cursive; background-color: #E2F1FF; height: 50px; width: 245px; color: black; font-size: 25px; outline: none; box-shadow: 4px 4px 15px 2px #AFC4D7; opacity: 0.9; position: relative; left: 250px; } textarea { font-family: 'Combo', cursive; background-color: #E2F1FF; height: 240px; width: 240px; position: relative; bottom: 83%; color: black; font-size: 25px; outline: none; box-shadow: 4px 4px 15px 2px #AFC4D7; opacity: 0.9; resize: none; }.BtnColor1 { background-color: #C2EA92; width: 30px; border: none; border-radius: 2px; height: 30px; box-shadow: 1px 1px 15px #728F4E; }.BtnColor2 { background-color: #92EADD; width: 30px; border: none; border-radius: 2px; height: 30px; box-shadow: 1px 1px 15px #4E8F8C; }.BtnColor3 { background-color: #EA92A5; width: 30px; border: none; border-radius: 2px; height: 30px; box-shadow: 1px 1px 15px #8F4E55; }
