我正在尝试来自此 codepen https://codepen.io/aaroniker/pen/WNxoovJ的代码,它在带有类的 div 内的输入字段上效果很好,url-input
如代码笔所示。但是,当我将它全部放在一个带有 id 的 div 中wrapper
并添加一个 jquery-clone 函数来复制 时div.url-input
,它成功地复制了 HTML,但所有功能对于动态添加的字段都停止工作。我在页面的其余部分使用 jQuery,但这个 codepen 使用纯 javascript。
我怀疑这也是 forEach 循环内的事件侦听器的问题。这是我尝试过的:我尝试过的不是document.querySelectorAll('.url-input').forEach(elem => {
第 21 行
document.querySelectorAll('#wrapper').forEach(elem => {
然后是第 23、23、25 和 27 行,我使用了后代选择器,例如elem.querySelector('.url-input .icon')
,而不是elem.querySelector('.icon')
当我尝试上述方法时,即使初始url-input
字段停止工作,动态字段也没有触发。我如何将此代码合并到url-input
可以动态添加多个 div 的包装器中?
编辑:这是所有代码,包括克隆过程的脚本。“模板”标签包含用于 url 输入字段的 HTML 模板的缩小版本,以便于克隆。我还缩小了 CSS 样式,以节省空间。
