How to retrieve all the fields from a layer after clicking identify in Javascript

[QaziIqbal]

I am using identify onclick. I am able to get the attributes only with their specific names like
idResult.feature.attributes['FACIL_ID']

I want to retrieve all the fields and values from the attribute table of the layer.
Thanks

for a demo. use the following code:

var fields =[];
var fieldName;
for (attribute in idResult.feature.attributes)
{
    fields.push(attribute);
} 
for(var i=0; i<fields.length; i++)
{
    fieldName =fields;
    // field name
    alert(fieldName);
    // field value
    alert(idResult.feature.attributes[fieldName]);
}
