0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'add' / 'put'

Question

Hi,

When I used the following line, I got the error like:

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'add' . 

I am using :
<script src="//Microsoft.WinJS.1.0.RC/js/base.js"></script>
<script src="//Microsoft.WinJS.1.0.RC/js/ui.js"></script>

Any ideas about it? Thanks a lot.

IDBObjectStore.add("value", "key");

Hi

These is a W3C Indexed Database API, it's state is draft.

Your code can't work in normal html app, it's not a Win8 UI problem.

Please refer to this :

http://www.w3.org/TR/IndexedDB/#widl-IDBObjectStore-add-IDBRequest-any-value-any-key

add

This method throws a DOMException of type ReadOnlyError if the transaction which this IDBObjectStore belongs to is has its mode set to "readonly". If any of the following conditions are true, this method throws a DOMException of type DataError:

• The object store uses in-line keys and the <var>key</var> parameter was provided.
• The object store uses out-of-line keys and has no key generator and the <var>key</var> parameter was not provided.
• The object store uses in-line keys and the result of evaluating the object store's key path yields a value and that value is not a valid key.
• The object store uses in-line keys but no key generator and the result of evaluating the object store's key path does not yield a value.
• The <var>key</var> parameter was provided but does not contain a valid key.

Otherwise this method creates a structured clone of the <var>value</var> parameter. If the structure clone algorithm throws an exception, that exception is rethrown. Otherwise, run the steps for asynchronously executing a request and return the IDBRequest created by these steps. The steps are run with this IDBObjectStore as <var>source</var> and the steps for storing a record into an object store as <var>operation</var>, using this IDBObjectStore as <var>store</var>, the created clone as <var>value</var>, the <var>key</var> parameter as <var>key</var>, and with the <var>no-overwrite flag</var> flag set to true.

Parameter	Type	Nullable	Optional	Description
value	any	✘	✘	The value to be stored in the record
key	any	✘	✔	The key used to identify the record

Exception

Description

DOMException

TransactionInactiveError The transaction this IDBObjectStore belongs to is not active. ReadOnlyError The mode of the associated transaction is "readonly". DataError The calculated key for the insertion was not a valid key. Also thrown if the calculated key for any of the indexes which belong to this object store had a calculated key which was not a valid key InvalidStateError Occurs if a request is made on a source object that has been deleted or removed. DataCloneError The data being stored could not be cloned by the internal structured cloning algorithm.

Return type: IDBRequest
