一、Storage事件的接口代码如下所示：

interface StorageEvent:Event{
    readonly attribute DOMString key;
    readonly attribute DOMString? oldValue;
    readonly attribute DOMString? newValue;
    readonly attribute DOMString url;
    readonly attribute Storage? storageArea;    //storageArea属性指向事件监听对应的Storage对象
    void initStorageEvent(in DOMString typeArg,
                          in boolean canBubbleArg,
                          in boolean cancelableArg,
                          in DOMString keyArg,
                          in DOMString oldValueArg,
                          in DOMString newValueArg,
                          in DOMString urlArg,
                          in Storage storageAreaArg);
    };

二、在下面这段代码中，当提交form表单时，第二个（外部的）表单会随第一个一起提交。因为外部的<input>增加form属性，并制定form的ID值为testform，外部的<input>就属于form表单范围。

<form id="testform">
<input type="text" />
</form>
<input form=testform />
