About to make the selected content as bold, you can't do that directly in the textarea but you can do that using editable divs. This plugin could help you: http://mistic100.github.io/jquery-highlighttextarea/
要将所选内容设为粗体，您不能直接在 textarea 中执行此操作，但可以使用可编辑的 div 执行此操作。这个插件可以帮助你：http: //mistic100.github.io/jquery-highlighttextarea/
About your comment: "How can i get the all text from a div excluding html tags?" you can use something like this: jQuery('.yourDiv').text();
关于您的评论：“如何从 div 中获取除 html 标签之外的所有文本？” 你可以使用这样的东西：jQuery('.yourDiv').text();
