如何動態刪除或重置一個javascript對象的元素

我想從其父對象中刪除一個對象沒有成功...當我直接使用'刪除'它的作品，但是當我在一個多重對象循環，我無法讓它工作？我在做什麼錯在低於$。每個循環：如何動態刪除或重置一個javascript對象的元素

<script> 
rc = { oc: { 'Amt': 30, 'mpA': 3000, 'ipP': 1, 'ppP': 12, 'mpP': 12000 }, 
     tb: { 'Amt': 2000, 'mpA': 100000, 'ipP': 1, 'ppP': 12, 'mpP': 12000 }, 
     bl: { 'Amt': 300, 'mpA': 100000, 'ipP': 1, 'ppP': 12, 'mpP': 12000 } } 

var carObj = {} 
carObj['name'] = 'carObj'; 
console.log (' when created: carObj: ', carObj); 

carObj['rc'] = rc; 
console.log ('when rc Loaded: carObj: ', carObj); 

delete carObj['rc']; 
console.log ('when rc deleted: carObj: ', carObj); 

// up till here delete works as expected. 
    // create two objects 
var carObj1 = {} 
var carObj2 = {} 
    // load objects with the 'rc' object 
carObj1['name'] = 'carObj1'; 
carObj1['rc'] = rc; 
console.log ('when rc Loaded: carObj1: ', carObj1); 

carObj2['name'] = 'carObj2'; 
carObj2['rc'] = rc; 
console.log ('when rc Loaded: carObj2: ', carObj2); 


// !!! Here is where delete doe not work. i don;t get any errors, only rc not deleted from c 
$.each([carObj1, carObj2], function (index, c){  
    console.log('before deleting rc', c); 
delete c[rc]; 
console.log('After deleting rc', c); 
}); 
</script>
