[Javascript] deleting all options

[Peter Brunone]

Paul,

   What browsers/platforms demonstrate this DOM blindness?  I've been using innerHTML to build the rows in EasyListBox and I've never found the DOM to be unaware of the elements I've added...

Cheers,

Peter

I sometimes use it to delete markup but never to insert it -- unless I don't need to read or manipulate the elements in the markup I'm inserting.I wonder if this blindness of the DOM to markup inserted using innerHTML is one of the 'widely differing implementations' we're warned against:___________________________innerHTML sets or gets all of the markup and content within a given element...Though not actually a part of the W3C DOM specification, this property provides a simple way to completely replace the contents of an element. For example, the entire contents of the document body can be deleted by:document.body.innerHTML = ""; // Replaces body content with an empty string....As there is no public specification for this property, implementations differ widely. It should never be used to write parts of a table - W3C DOM methods should be used for that - though it can be used to write an entire table or the contents of a cell.ref: http://developer.mozilla.org/en/docs/innerHTML___________________________Paul _______________________________________________Javascript mailing listJavascript at LaTech.eduhttps://lists.LaTech.edu/mailman/listinfo/javascript
