HTML文档中的Rich Text Editors如何实现其丰富的文本格式？ [英] How do Rich Text Editors in HTML documents achieve their rich text formatting?

问题描述

可以请您解释文本区域中的文本在富文本编辑器中的样式吗？我试图在表单中设置样式文本，但不会改变。

JS是否识别用户输入的字符？如何完成？

解决方案

我认为答案是你正在看的是通常不是实际的< textarea> 。这是一个< div> 或< span> 使其看起来像一个文本区域。

富文本编辑器将具有修改内容的控件具有常规html标记（< strong> ，< em> 等）的span /一个完整的富文本编辑器

Could you please explain how the text in the textarea gets styled in rich-text editors? I've tried to style text in the form but it doesn't change.

Is it JS that recognizes characters typed by the user? How's that done?

解决方案

I think the answer is that what you're looking at is typically NOT an actual <textarea>. It's a <div> or <span> made to look like a text area. A regular HTML textarea doesn't have individual formatting of the text.

"Rich-Text editors" will have controls that modify the contents of the span/div with regular html markup (<strong>, <em>, etc.) to emulate a full-blown rich text editor
