资源说明：An IndexedDB Plugin for Jquery.
Jquery Plugin for the IndexedDB API [](https://travis-ci.org/axemclion/jquery-indexeddb)
===============================================================================================================================================================================
IndexedDB is a database inside a browser to save and retrieve objects on the browser/client. The JQuery IndexedDB Plugin is a wrapper on the IndexedDB API for JQuery.

Summary
-------
The Jquery IndexedDB Plugin brings to goodness of Jquery to the browser's native IndexedDB API. It supports method chaining, promises and smart defaults, enabling you to get more done with less code. It also abstracts out differences in browser implementations.
Code
----
The code written with the jQuery plugin is pretty simple. It looks something like
```javascript
$.indexeddb("BookShop-1").objectStore("BookList").openCursor().each(write);
```
A typical operation using the IndexedDB API would involve using the request model, creating transactions, checking for existence of object store using error responses and exceptions and then finally getting to the part where the data is actually iterated over.
```javascript
var request = window.indexedDB.open("BookShop-1");
request.onsuccess = function(event){
var db = request.result;
var transaction = db.transaction(["BookList"], IDBTransaction.READ_WRITE);
var objectStore = transaction.objectStore("BookList");
var request = DAO.objectStore.openCursor();
request.onsuccess = function(event){
var cursor = request.result;
if (cursor) {
write(cursor.key + "" + cursor.value);
cursor["continue"]();
}
};
};
```
