NN2 NN3 NN4 NN6 IE3 J1 IE3 J2 IE4 IE5 Compatibility While the execCommand method offers several commands that insert HTML elements into a text range it is probably more convenient to simply paste fully formed HTML into the current text range assuming you need to be working with a text range instead of even more simply setting new values to an element object s outerHTML property . Provide the HTML to be inserted as a string parameter to the pasteHTML method. Use the pasteHTML method with some forethought. Some HTML that you may attempt to paste into a text range may force the method to wrap additional tags around the content you provide to ensure the validity of the resulting HTML. For example if you were to replace a text range consisting of a portion of text of a P element with for instance an LI element the pasteHTML method has no choice but to divide the P element into two pieces because a P element is not a valid container for a solo LI element. This division can greatly disrupt your document object hierarchy because the divided P element assumes the same ID for both pieces. Existing references to that P element will break because the reference now returns an array of two like-named objects.
