(IE6) 将内容插入到当前光标位置的 iframe 中
我目前正在升级基于 DHTML 编辑器控件 (DEC) 的所见即所得富文本编辑器,以便在现代浏览器中使用更现代的编辑器控件。我正在使用打开设计模式的 iFrame 以及常规 javascript 和 jquery 的混合。
我的要求之一是将 html 内容(表单等)插入 iframe 中,以便用户可以编辑它们。我可以在 FF + Chrome 中使用它,但 IE 却很痛苦。我当前的代码将内容插入到父文档的开头而不是 iframe,我使用的是 Selection.createRange() 函数,当与 DEC 一起使用时,如果选择了控件,则将在光标处插入内容,或者在如果没有,则在编辑器内的文档末尾。
目前,它仅在我在 IE 中选择某些文本时才有效。这是我当前的代码(抱歉,如果它看起来未格式化,工作中的防火墙阻止了 stackoverflow 中的大量 css + js),有什么想法吗?

I'm currently upgrading a WYSIWYG Rich Text Editor that was based on the DHTML Editor Control (DEC) to use the more modern editor controls in modern browsers. I'm using an iFrame with design mode turned on and a mixture of regular javascript and jquery.
One of my requirements is to insert html content (forms etc) into the iframe so that users can edit them. I have it working in FF + Chrome, but IE is proving a pain. My current code inserts the content at the start of the parent document and not the iframes, I'm using the selection.createRange() function that when used with DEC would insert the content either at the cursor if the control was selected or at the end of the document inside the editor if not.
Currently it only works when I select some text in IE. Heres my current code (apologies if it looks unformatted the firewall at work is blocking a lot of the css + js from stackoverflow), any ideas?

使您的按钮不可选择,以防止它从 iframe 中夺走焦点。您可以在 IE 中使用
uneselectable="on"
执行此操作:Make your button unselectable to stop it nicking the focus from the iframe. You can do this in IE using
uneselectable="on"
