I'm working on a search component for an app I'm working on and I needed to add some filters to it. I've found an example and got the first filter working fine.
Now I'm trying to add a second filter I'm running into problems... In the example I found they use filterFunctions, but I only get an option for filterFunction, why is that?
Here's the example code
productsCollection.filterFunctions =
[
filterByPrice, filterByType,
filterByCondition, filterByVendor
]
And this is what I'm trying
acData.filterFunction = [filterByStatus, filterByDate]
but with this code I get the following error message - 1067: Implicit coercion of a value of type Array to an unrelated type Function.
Why am I getting this error and how would I go about add multiple filters to my Array Collection?
Thanks!
filterFunction
must be set to a single function, not an Array
or any other datatype. To combine multiple functions create one that combines them, like this:
acData.filterFunction = function(item:Object)
{
return
filterByPrice(item) &&
filterByType(item) &&
filterByCondition(item) &&
filterByVendor(item);
};
If you saw a sample that used filterFunctions
plural that accepted an array, post a link. That's not anywhere in the standard Flex framework or in the new 4.0 beta afaik.
