condition for value not in array or value different from all elements in array

Hi I would like to find a condition in jquery to be sure that the id of the data found by .grep is different from all the values from a vector, with something like this : 

var matchedAgainstBrand = $.grep(prodata, function(v,i) {
    return v['id'] !== matchedProIds ;
});

or this

var matchedAgainstBrand = $.grep(prodata, function(v,i) {
    return $.inArray( v['id'], matchedProIds ) == -1;
});

(but these two do not work !)

where matchedProIds is a vector of integers, defined like this :

var matchedProIds = [];
for (i=0; i< matchedPro.length; i++) {
     matchedProIds.push(matchedPro[i]['id']);
}

Can you help with a condition that (un)match a value against a vector ?

Thanks to the suggestion from @Matt Burland :

var matchedAgainstBrand = $.grep(prodata, function(v,i) {
    return matchedProIds.indexOf(v['id']) == -1;
});
