建立表單對(duì)象，表單名：name=form，并建立checkbox，命名：name="checked"
建立全選按鈕，代碼：
<INPUT title=選擇所有的Banner，點(diǎn)擊選定按鈕 onclick=CheckAll(this.form) type=button value=全選 name=chkall style="cursor:hand">
建立反選按鈕，代碼：
<INPUT title=反向選擇所有的Banner，點(diǎn)擊選定按鈕 onclick=CheckOthers(this.form) type=button value=反選 name=chkOthers style="cursor:hand">
