完全从源中删除标记 [英] Completly remove a tag from the source

问题描述

我想删除类别为.de的标记。

I would like to remove a tag with the class of '.de'.

$（'。de'）。remove（ ）; 会将其从页面中删除但是当我检查源代码时，我仍然会看到标记。

$('.de').remove(); will remove it from the page but when I check the source code, then I still see the tag.

我遇到的问题是，需要从表单中删除以下标记，否则它将被发送，而这不是我想要的。

The problem that I have is, the following tag needs to be removed from the form, otherwise it will get sent and that's not what I want.

<input class="input_field_left de" name="friend_vorname[]" type="text" placeholder="Vorname">

或者还有另外一种方法可以不让这个字段被发送？！

Or maybe there is another way to not let this field get sent?!

推荐答案

这就是查看源在浏览器中的工作原理。它向您显示来自服务器的内容（通常从服务器重新查询它[可能从缓存中读取]），不页面中当前的内容。

This is just how "view source" works in browsers. It shows you what came from the server (and usually re-queries it from the server [which may read it from cache]), not what is currently in the page.

要查看页面中当前的内容，您需要在浏览器的开发工具中使用元素或DOM选项卡（通常通过F12或Ctrl + Shift + I打开）。您通常可以通过右键单击页面上的元素并选择Inspect element来打开它并移动到特定元素，因此如果您在 $（'。de'）之后使用表单执行此操作.remove（）; 运行后，你会看到没有 .de 元素的表单。

To see what's currently in the page, you need to use the "Elements" or "DOM" tab in your browser's dev tools (usually opened via F12 or Ctrl+Shift+I). You can usually open it and move to a specific element by right-clicking that element on your page and choosing "Inspect element", so if you do that with your form after your $('.de').remove(); is run, you'll see the form without the .de elements in it.

不，它不会。您的 $（'。de'）。remove（）; 将从页面中删除任何匹配的元素，如果表单随后提交，则不会随表单一起提交。

No, it won't. Your $('.de').remove(); will remove any matching elements from the page, and they will not be submitted with the form if the form is then submitted.
