How to get particular data from document 

Example in sql 

SELECT * FROM TABLE WHERE ID='101' 


i have created map function in couchDB(Futon) : 


function(doc,val) { 
  if(doc.amount=='1') {   // here instead of '1' i  can use variable val(2nd
argument of the fun) 
    emit(doc.amount, doc.name); 
  } 
}

my jquery code is : 

*
 $(document).ready(function() { 
var db = $.couch.db(window.location.pathname.split("/")[1]); 
$("#dataview").empty(); 
db.view("myDesign/myView", { 
success: function(data){ 
data.rows.map(function(row) {
 / //my printing logic goes here
 // here i can able to get all the data irrespectively. 
// which condition i need add to get specified record. 
// how to use above function using jquery/ 
}); }, 
error: function(req, textStatus, errorThrown){
alert('Error '+ textStatus);} 
});
 }); 
*
