如何恢复用jQuery删除的元素? [英] How to Restore an Element Removed with jQuery?

问题描述

如果使用删除元素

$('.notification').remove();

我们如何重新创建它.

推荐答案

您无法获取该特定实例.使用$.remove()会将其从DOM中删除.您可以创建它的副本，在DOM中移动它，隐藏它，等等.根据您的项目要求，您可能还有许多其他选择.

You can't get that particular instance back. Using $.remove() removes it from the DOM. You can create a clone of it, move it around the DOM, hide it, etc., though. Depending on what your project requires, you likely have many other options.

如果您对该特定实例不太感兴趣，则可以创建一个新实例.假设那是一个带语句的div:

If you're not too interested in that particular instance, you can create a new one. Suppose that was a div with a statement:

$("<div />").addClass("notification").text("I exist!").appendTo("body");

如果要保留该特定元素的副本，可以$.clone()并删除原始元素:

If you want to keep a copy of that particular element around, you can $.clone() it and remove the original:

var clone = $(".notification").clone(); // making zeh' clones!
$(".notification").remove();            // original is gone
$("body").append(clone);                // appears to have returned
