Adding and retrieving from sessionStorage


Adding and retrieving from sessionStorage

I wish did fix the issue. You can store only strings in sessionStorage so before store it, first do stringify() and at the time of retrieval again parse it to JSON.
at the time of saving:
code :
$window.sessionStorage.setItem("JsonObj", JSON.stringify([
   {url: ""},{},{}
]));
JSON.parse($window.sessionStorage.JsonObj)[0].url

wish help you to fix your issue Your GetKeyForItem override is what specifies the key for an item. From the docs:
code :
MyCollection col = new MyCollection();
MyClass myClass = new MyClass();
myClass.Key = "This is the key for this object";
col.Add(myClass);

this one helps. The argument for your searchforPrice method should rather be called product than price.
Now, you're addPrice method is wrong, because it doesn't add any price. It just returns the price of the currently selected item in the combo. It should probably look like this:
code :
public int addPrice()
{
    DataSet ds = searchforPrice(comboBox2.Text);
    int sum = Convert.ToInt32(maskedTextBox10.Text);
    int price =  Convert.ToInt32(ds.Tables[0].Rows[0]["Price"]);
    return sum + price;
}

Hope this helps $sessionStorage is an AngularJs service found at: https://github.com/gsklee/ngStorage
It allows you to read and write to $localStorage and $sessionStorage, making use of these stored parameters during the lifetime of your session.
code :
var whatIsInMyStorage = $localStorage; // or $sessionStorage; 
$sessionStorage.$reset();
$localStorage.$reset();
storing and retrieving ajax xml response in sessionStorage

it should still fix some issue The issue you have is that sessionStorage can only hold strings. Due to this the XMLDocument is being coerced using toString(), hence the value you're seeing.
To fix this you need to serialise the XMLDocument manually before saving it. Try this:
code :
$.ajax({
  url: '/webservice.svc/getProfile',
  data: { 
    memberId: $(authenticateResponse).find("memberId").text() 
  },
  method: "GET",
  success: function (d) {
    sessionStorage.clear();
    sessionStorage.setItem('ALMS', new XMLSerializer().serializeToString(d));
  }
});

Does that help Note: I changed my hashmap key to int, if you want to use String then you need to make necessary changes
changes to store account
code :
public boolean store(Account account) {
    /* adds a new Account to the accounts Map. The key is the account’s ID. This
     * method should return a Boolean object that is "true" when the Account added
     * to the ledger is being added for the first time, "false" if it is being
     * updated. Check the documentation for the Map.put() method for reference.
     */
    int key = account.getAccountID();
    if(accounts.containsKey(key) != null){
        accounts.put(key, account);
        return true;
    }
    return false;
}
public Account retrieve(int accountId) { 
    /* returns a single Account with the specified accountID from the accounts Map.
     * If none is found, return null.
     */ 
    if(accounts.containsKey(accountId)) {
        return accounts.get(accountId);
    }
    return null;
}
public Account createAccount(String accountType, String firstName, String lastName) {
    /* this method creates and returns a new Account object with the specified
     * parameters (type, firstName, lastName). Calling this method should store the
     * new account within the accounts Map. Please note the first parameter passed
     * into this method determines which account type (CheckingAccount vs.
     * SavingsAccount) to create. The values should either be “checking” or
     * “savings”.
     */

    int accountId = getNextAccountID();
    Account acc;
    if(type == "checking"){
      acc = new CheckingAccount(id, type, firstName, lastName);
    } else {
      acc = new SavingAccount(id, type, firstName, lastName);
    }
    return acc;
}
public Integer getNextAccountID() {
    /*this is a helper method that can be used to find out what the next 
     * accountID will be based on the number of Accounts within the accounts Map.
     * It should return the size of the accounts Map plus one.
     */ 

    return accounts.size() + 1;
}
