html5 初试 indexedDB(推荐)

var keyRange = IDBKeyRange.lowerBound(0);

var cursorRequest = store.openCursor(keyRange);

cursorRequest.onsuccess = function(e) { var result = e.target.result;

if(!!result == false) return;

renderTodo(result.value);

result.continue(); };

cursorRequest.onerror = adsageIDB.onerror;

};

function renderTodo(row) { var todos = document.getElementById("todoItems");

var li = document.createElement("li"); var a = document.createElement("a");

var t = document.createTextNode(row.text);

a.addEventListener("click", function() { adsageIDB.deleteTodo(row.adsid);

}, false);

a.textContent = " [删除]"; li.appendChild(t);

li.appendChild(a); todos.appendChild(li)

}
