setting text, change the font

[Mr. x]

Hello,

Suppose I have a table like this :

<table width = "580">
<tr align = "right" width = 760>
<td id = "current_page_i nner">
<font size="4" color="lightgre en" face="arial"><b ><i>
abc
</i></b>
</font>
</td>
</tr>
</table>

....
if I do in code :
current_page_in ner.children(0) .innerText = "bcd"
the text is changed to the new text,
and the font doesn't change,
but the font is not italic and not bold as the original.
Why ?

Thanks :)

I recommend against using the font, b and i tags. Use CSS to get
the same effect, that is what it was invented for.
</font>
</td>

Amazing, out of the three parts of the expression on the left of
the equal sign, all are IE-specific and won't work in Mozilla.

It is bad style to refer to an element by using its name as a global
variable (bad style, and not likely to work in many browsers, including
Mozilla).
Use the W3C DOM method "getElementById " instead:
document.getEle mentById("curre nt_page_inner")

The children collection is not standard code. Again, it probably works
in IE, but doesn't in Mozilla/Netscape 6+. Use the W3C DOM "childNodes "
collection instead:

document.getEle mentById("curre nt_page_inner") .childNodes[0]

Likewise "innerText" is a proprietary MS property that doesn't work in
Mozilla. The W3C method isn't as short, so I won't show it here.

Why ?

Because the first child of the element named current_page_in ner is the
font tag (in IE, in Mozilla it is a text node containing the newline
between the td and the font elements). You set the innerText of the
font tag to "bcd". That clears *all* the content of the font tag and
adds a single text node with the text "bcd".

It is equal to this W3C DOM code (ok, I will show it here :)

---
var elem = document.getEle mentById("curre nt_page_inner") .
getElementsByTa gName("*")[0]; // first non-text-node
while (elem.hasChildN odes()) { // remove content
elem.removeChil d(elem.lastChil d);
}
elem.appendChil d(document.crea teTextNode("bcd ")); // add new content
