Trích từ AVIM source code:
Mã:
wi=getElementById('iframe_id').contentWindow
iframedit=wi.document;iframedit.wi=wi
....
//w==e.target.parentNode.wi (iframedit.wi)
var sel=w.getSelection()
....
range=sel?sel.getRangeAt(0):document.createRange()
.....
var node=range.endContainer
.....
//node.data = đoạn text trong iframe
//Dùng node.deleteData đế xóa & node.insertData để thêm dữ liệu.

Em có đoạn JS này mà không biết tô màu nền cho nó như thế nào. Mặc định là nó không có màu nền. Height là 100px và em muốn tô màu toàn bộ 100px này. Mong các anh chỉ giúp. Xin cám ơn.

Ko được thì chỉ có chú làm sai thôi. Chứ còn chính chú vẫn đang gõ tiếng Việt ầm ầm đấy thôi.
