Answer 1

It seems that you can't do it with the execCommand directly Documentation of the commands an other one .

You can still do it in jQuery, after adding the image (seems a bit hackish, I know, but don't think you can do better) :

$('img[src="smiley.gif"]').attr('alt','Smiley face');

Answer 2

您可以这样使用insertHTML命令：

document.execCommand('insertHTML', 0, '<img src="' + newUrlValue + '" alt="' + newAltValue + '" />');
