Error 'length is null or not an object' in IE8

nicola.peluchetti

Hi,

i have a problems on a particular table: in firefox everything is ok, but in IE8 i always get the error shown in the title. It points to line 719 of datatables 1.7.4 (i'm using jquery 1.4.4).

this is the code at line 719

[code] function ( sData )
{
/* Allow zero length strings as a number */
if ( sData.length === 0 )//Line 719
{
return 'numeric';
}
[/code]
i think thata the problem is that sData is null, because if i put
[code]
if (sData == null){
sData=''
}
[/code]

i don't get the error anymore, but i still get the same type of error in some other point. Has anyone experienced a behaviour like this?

The problem appears to be in my aoColumns definition:

[code]
"aoColumns": [
null,
null,
null,
{ "bVisible": false} ,
null,
null,
null,
null,
null,
null,
null,
null
]

[/code]
if i remove it, there is no error

The problem was in the space after { "bVisible": false}!

I had the same problem.
Thanks for pointing out the cause Nicola.
But Microsoft... how is that an error? If anything, the error is in the parser.

I have just had a similar problem, and clearing all spaces, new lines, carriage returns and tabs from the code passing parameters solved it for me - thanks to nicola.peluchetti for pointing me in the correct direction.
