Question

是否有办法(除了园艺图书馆之外)改变内容 Editable Divinner Rainbow on the air, as on keyup, with no cursor status /cus loss? 我只想使用纯javascript代码,尽可能简单。

例如:

<div id="divId" contentEditable="true" onkeyup="change(this)"></div>

然后是 j:

function change(element)
{
  element.innerHTML = element.innerHTML.replace(/.../,  ... );
}

感谢。

如果你重新取代超文本,你将需要一些节约和恢复选择的手段。备选办法如下:

Insert elements with IDs at the start and end of the selection before the HTML replacement, retrieve them by ID afterwards and move the selection boundaries using those elements. This is the most robust method and is what Rangy does.
Store some kind of character-based offset for the start and end of the selection before the HTML replacement and recreate the selection afterwards. This has all kinds of problems in the general case but may be good enough, depending on your needs. I ve posted functions on SO to do this before that depend on Rangy, but you could easily strip out the Rangy stuff if you don t mind losing support for IE < 9.
Store and restore selection boundaries by pixel coordinates. Browser support for this is not good and will not be suitable if your HTML replacement changes the layout.

这没有利用关键事件,但可能已经足够了? 适用于贵机构的说明显然只针对某一要素。

document.body.contentEditable= true ;
document.designMode= on ;
void 0;
