Hi Robert,
Just two questions?
1 - is it possible to call two functions from the onload event?
<body onload="doIt('test', 5)"; "testTrue()";>
2 - is it possible to set the target using code??
I know we can use the location.href = "test.htm" to create a link but what
about the target?? how do I set it?? this does not work:
location.href = "test.htm target='main'";
Cheers,
Claudio
> Hi Claudio,
I don't think that it regards the TABLE element as null.
parent.frames[1].rightBottom.document.getElementsByTagName("table") !=3D
null
Just check for :
parent.frames[1].rightBottom.document.getElementsByTagName("table")
or perhaps:
if(typeof
parent.frames[1].rightBottom.document.getElementsByTagName("table") =
=3D=3D
"object")
If this doesn't work, create a variable in the other frame that is set
to true when the page is fully loaded.
As in:
<html>
<head>
<title>A title</title>
<script language=3D"JavaScript" type=3D"text/javascript">
var bIsLoaded =3D false;
window.onload =3D function (){
bIsLoaded =3D true;
}
</script>
</head>
<body>
</body>
</html>
And then change:
if(parent.frames[1].rightBottom.document.getElementsByTagName("table")
!=3D null) {
to:
if(bIsLoaded)

=C4mne: [javascript_howto] CHECK FOR NULL VALUE
Hi,
Two weeks ago Robert showed me how to create a function that would
highlight the <td>s of a table according to some criteria. This works
wonderfully well.
However, since I am using frames, I have to make sure that all the
frames are loaded. If the user clicks on the highlight button before the
bottom frame is loaded then I get an alert saying that the bottom frame
is null.
I have tried to use an "if" statement to check if the frame is null but
it is not working.
Any ideas why this "if" statement is not working?
Cheers,
var bColoredTDs =3D false;
function HighlightIndexTD()
{
if(parent.frames[1].rightBottom.document.getElementsByTagName("table")
!=3D null) {
var arrTables =3D
parent.frames[1].rightBottom.document.getElementsByTagName("table");
for(var i=3D0; i<arrTables.length; i++)
{
if(i > 0)
{
var arrAllCurrentTableRows =3D
arrTables[i].getElementsByTagName("tr");
for(var j=3D0; j<arrAllCurrentTableRows.length;
j++)
{
var oAllCells =3D
arrAllCurrentTableRows[j].getElementsByTagName("td");
with(oAllCells[oAllCells.length - 1])
{
var intValue =3D
parseInt(innerHTML, 10);
if(!bColoredTDs && (intValue <
80 || intValue > 120))
{
style.color =3D "white";
style.backgroundColor =3D
(intValue < 80)? "blue" : "red";
}
else
{
style.color =3D "black";
style.backgroundColor =3D
"white";
}
}
}
}
}
bColoredTDs =3D (bColoredTDs)? false : true;
else
{
alert("Choose a Report");
}
}
