children["id"].innerText - does not work with netscape but with explorer

[Julia Peterwitz]

I have a function that works with explorer but not with netscape.
The problem is the function at line 5.
1 fSetSelectedDay (myElement){
2 /*
3 ...
4 */
5 var elementText = eval(myElement. children["calDateTex t"].innerText);
6 /*
7 ...
8 */
9 }
10 <!-- ... -->
11 <td id=calCell onclick='fSetSe lectedDay(this) '>
12 <font id='calDateText ' onclick='fSetSe lectedDay(this) '>
13 <script> myMonth[w][d] </script>
14 </font>
15 </td>
16 <!-- ... -->
I need some support for this.
Thank you very much.

..innerText is IE only, and as such is not going to work in NS. use
innerHTML instead.

eval is not needed there:

var elementText =
document.getEle mentById(myElem ent).children(' calDateText').i nnerHTML;

the [ ] are also an IE-ism.

innerHTML instead.

Agreed, however...
var elementText =
document.getEle mentById(myElem ent).children(' calDateText').i nnerHTML;

....there are two problems with this line:

1) If you look at the OP's HTML, you'll see that myElement is a
reference to the element, not an id.
2) The children property is
a) a collection, so the brackets were correct,
b) also a Microsoft-ism.

Perhaps

var elementText = myElement.child Nodes[ 'calDateText' ].innerHTML;

would be better (preferably with feature detection)?

[julia peterwitz]

myElement.child Nodes[ 'calDateText' ].innerHTML;
is also not working
(it neither works in explorer nor in netscape)

any other proposals for netscape??

solution for explorer again:
myElement.child ren["calDateTex t"].innerText;

Oops. I assumed that childNodes was a standard collection that could be
indexed by name/id as well as ordinal. However, I just thought that
'calDateText' is an id, so why don't you just use

document.getEle mentById( 'calDateText' ).innerHTML

?

You don't say which Netscape. If it's Netscape 4, your options are
very limited. If it's Netscape 6+, i.e., based on Mozilla, then
you can pretty much fly :) I'll assume Netscape 6+.
5 var elementText = eval(myElement. children["calDateTex t"].innerText);
I see three problems:
- innerText is IE only.
- children is IE only.
- eval is evil.

There are different options, depending on how standards compliant you
want to be. I'll go for full compliance with the DOM specification
(i.e., avoiding innerHTML).

A version that collects the string content of the calcDateText element
(not recursively, so don't put the text to find inside tags).
---
var span = document.getEle mentById("calcD ateText");
var elementText = "";
for(var chld = span.firstChild ; chld; chdl=chld.nextS ibling) {
if (chld.nodeType == 3) { // text node
elementText += chld.nodeValue;
}
}
---
Or, change the first line to:
---
var span = myElement.getEl ementsByTagName ("span")[0];
---
(Notice that I use "span" instead of "font" as commented later)
11 <td id=calCell onclick='fSetSe lectedDay(this) '>
12 <font id='calDateText ' onclick='fSetSe lectedDay(this) '>
The font tag is deprecated and you are not using any of its specific
attributes anyway. Change it to a <span> instead, that is just what
you need: a meaningless wrapper.
13 <script> myMonth[w][d] </script>
The type attribute is required on script tags, so:
---
<script type="text/javascript">
---
Do you mean to document.write the value?
---
document.write( myMonth[w][d]));
---
Where are "w" and "d" calculated? (Meaning Week and Day?)
14 </font>

</span>

yes, I thought about netscape 6+

var font= myElement.getEl ementsByTagName ("font");

until here it works.
but the following doesn't start.
and I don't know why.
but there is no error message.
for(var chld = font.firstChild ; chld; chdl=chld.nextS ibling) {
if (chld.nodeType == 3) { // text node
elementText += chld.nodeValue;
}
}

I removed the irrelevant attributes.
so I will use <font> further on.

13 <script> myMonth[w][d] </script>
The type attribute is required on script tags, so:
---
<script type="text/javascript">
---
Do you mean to document.write the value?
---
document.write( myMonth[w][d]));

sorry I forgot to put the document.write around

13 <script> document.write( myMonth[w][d]); </script>

this function notes the days of the months, but this is irrelevant for
the problem. isn't it?
---
Where are "w" and "d" calculated? (Meaning Week and Day?)

14 </font>

</span>

Damn! :(
That would be the typo: ^^^^ shoud be chld.

That would mean that the loop goes on forever ... doing nothing.

/*

alert("1");
var font = myElement.getEl ementsByTagName ("font");
alert("2");
var elementText = "";
alert("3");
for(var chld = font.firstChild ; chld; chld=chld.nextS ibling) {
alert("4");
if (chld.nodeType == 3) { // text node
elementText += chld.nodeValue;
}

/*

when I start this I'll get the alert's 1,2,3 but the alert 4 doesn't start.
so I think there is something wrong.
but I don't know what.

elementText = document.getEle mentById('calDa teText').innerH TML;
alert(elementTe xt);

good idea, but elementText is "".
do you know why?
