Array parameter does not accept a function that returns an array

I have a function called getFieldsArray() that returns an array of field names; something like
[ "field1", "field2" ]
I've taken pains to confirm that my function works as expected and returns an array.

I'm trying to figure out why the following code does not work:

var l_sDocXML = this.exportAsXFDFStr(
{
bAllFields : true,
aFields : getFieldsArray()
bNoPassword : true,
bAnnotations : false
});

If I assign the aFields parameter with a static array, everything works fine, but it won't work with a function that returns an array.

Any thoughts/insights?

Might not be it, but I think there should be a comma after the call to getFieldsArray(). Also, are there any error messages?

Congrats on your 1,000th post!

You're right about the comma--the code here is a bit simplified but captures the essential issue.

I'm not getting any error messages or syntax errors. The string return from the exportAsXFDFStr() call simply does not contain data from the fields.

Could you post the source code of getFieldsArray() ?

I hope this won't complicate matters too much. getFieldsArray() is an object method that returns an array of field names. I've tested it separately and I'm confident that it's not the source of the issue.. but I'm certainly not immune to coding bloopers.

getFieldsArray:
function()
{
var l_aFields = [];
for (var i = 0; i < this.fields.length; i++)
{
try
{
switch (this.fields[i].type)
{
case "checkbox":
case "combobox":
case "listbox":
case "radiobutton":
case "text":
l_aFields.push('"' + this.fields[i].name + '"');
break;
}
}
catch (error) {}
}
return l_aFields;
}

};

Not sure why, cos I had tried this earlier, but it's now working after I removed the quotes from my function:

case "text":
l_aFields.push(this.fields[i].name);

You were pushing the string with quotes around it (as a part of the text itself), which later caused a problem because the names of the fields do not contain quotes.

I get that, but I only did that after it wasn't working initially. I must have done something wrong somewhere else.. glad it's working now as would be expected.

Thanks for your assistance!
