Set selected attribute on DOM created select options 1

[theniteowl]

I am rebuilding a select box using the DOM add() method.
Any way to set the selected attribute through this method so I do not have to loop through the whole set later comparing values in order to set selected correctly?

Never mind, found it.

myobj.setAttribute('selected', true);

niteowl, to answer your original question:

Using the add method you cannot set an item to selected, you will have to use a secondary method as you showed above in your 2nd thread. Here's the w3c's definition of the add method:

As you can see the constructor method only accepts 2 values, and neither of them define the "selected" status.

However, if you use the Option object, you can set a new option initially to "selected". Here's a reference to the Option object and a detailed explanation of it's constructor:

Thanks Kaht, that will be useful in the future.

I actually got around the problem in this case by testing the previously selected text value against the new text values as they are being created and kept track of the new index number so at the end of the function I could set the appropriate selectedIndex against the already created options.

I did it this way for other reasons based on how I assigned the value and text properties and filtered which options to display. Which options would show is dependent on values in the database but also upon an external value I had to test against.

It's one of those situations where the solution is very simple to look at but took a log of thinking and testing to come up with.

This situation is unusual though and in the future I will make use of what you showed above.
