Getting list of fields from identified feature

MarkSmith

Hello,
Please help, I've been trying to return a list of field names from a feature when identified, I think it has something to do with fieldAliases but I can't find an example of it being used in code.  I can run through the features one by one and retrieve attributes by hard-coding a field name like so: val = idResult.feature.attributes['UNIQUE_ID'], but I want to write some generic code so I don't have to hard code the field names.
Below is the identify function which is looping through the identified features, can someone please post the few lines necessary to get the field names?  Thanks again, Mark.

function addToMap(idResults, evt) {
for (var i=0, il=idResults.length; i<il; i++) {
    var idResult = idResults;

    //Get attribute for a given field name
    val = idResult.feature.attributes['UNIQUE_ID']

    //Instead of above line, need to get list of field names for this feature so I can loop through them

    alert(val)
}

I haven't tested this code so it may have typos/errors but I think the idea should be correct.

var i, fieldName, fieldValue, fieldNamesArr = [];

// This is how you can get the field names from an object.
for (fieldName in idResult.feature.attributes) {
    if (idResult.feature.attributes.hasOwnProperty(fieldName)) {
        fieldNamesArr.push(fieldName);
    }
}
// Now use the field names to retrieve attributes
for (i = 0; i < fieldNamesArr.length; i += 1) {
    fieldValue = idResult.feature.attributes[fieldNamesArr];
}
