Jquery adding loop to ajax parameters.

Jquery adding loop to ajax parameters.

I'm looking to dynamically add properties and values to my ajax
parameters, does anybody know how to do this? I can't seem to figure out
how to accomplish this task. Thanks
doLookup = function($field, url, query, process, filterIdArray) {
$field.addClass("ajax-wait");
return ajax(url, {
parameters: {
"t:input": query,
"t:inputFilter": $filterField.val(),
for (var i = 0; i < filterIdArray.length; i++) {
"t:inputFilter_" + i : $("#" + myStringArray[i]);
},
},
success: function(response) {
$field.removeClass("ajax-wait");
return process(response.json.matches);
}
});
};
