文本在Google网上论坛中设置，邮件正文但不显示？ [英] Text gets set in Google Groups, post-message body but does not display?

问题描述

我的扩展程序在内容脚本中写入Google Groups新主题页面的主题和消息正文。

更新后的主题显示得很好;它是输入类型文本，所以一切都很简单。但是，body是一个表示TextBox的div，当我写入时，更新不会出现：

我尝试将焦点置于首位，但没有任何效果。

解决方案

您如何设置文本？ 显示您的代码！

最初设置 contenteditable 元素的典型方式如下所示：

  var messageBody = document.getElementById（pb-0）; 
 messageBody.innerHTML ='< p>第1行。< / p>< p>第2行。< / p>';

请注意，使用 innerHTML 可以清除以前可能在文本框中的任何内容 - 对于这个问题的场景，这是可以的。

（对于更高级的更改/编辑，加载jQuery并使用它来添加/删除/替换编辑框中的节点，但是，这是一个不同的搜索和/或问题的主题。）

My extension, in a content script, writes to the subject and message body of the Google Groups "New Topic" page.

The updated subject is displayed just fine; it's of input type "text", so everything is easy. The body, however, is a div representing a TextBox, and when I write to it, the update doesn't appear:

I tried setting the focus to the field first, but that had no effect.

解决方案

How are you trying to set the text? Show your code!

A typical way to initially set a contenteditable element is like so:

var messageBody         = document.getElementById ("p-b-0");
messageBody.innerHTML   = '<p>Line 1.</p><p>Line 2.</p>';

Note that using innerHTML erases anything that might have been on the textbox before -- which is okay for this question's scenario.

(For more advanced changes/edits, load jQuery and use it to add/delete/replace nodes inside the edit box. But, that is a subject for a different search and/or question.)
