using a string with object name to refrence object

Re: using a string with object name to refrence object

If you are using Internet Explorer (5 onwards, I think), then you can use
the following...

function changeElement(s trId) {
document.getEle mentById(strId) .style = "background:yel low";
}

Alternatively, use a style sheet, then do...

function changeElement(s trId) {
document.getEle mentById(strId) .className = strYourClassNam e;
}

When passing values to the function containing the above you could use
changeElement(t his.id) when passing from an event from the specific element
you wish to change.

Hope some of this ramble makes sense to you!

That's not right, under default assumptions.

It is OK if we assume that the only person reading the page is its
author (I have a few like that); but in the World-Wide Web, which is the
default assumption here, it is the reader's browser that matters, not
the author's. Many authors do not think of that.

The proportion who are using browsers compatible with IE5 is large, but
it is not unity.

Before answering here, you should read and understand the regularly-
posted FAQ, linked below; section 2.3 in particular.

Look at the posts in this group, ignoring yours and mine; you will see
that the more intelligent users predominantly comply with paragraph 5 of
2.3, and in particular sentence 6 thereof. Responses should follow
trimmed quotes.

Jim - FAQ 2.3 para 2 sentence 2 last word should be words.
