            <img src="images/Logo.png" />
        </li>
    </ul>
</div>

#SettingWrap{
    display:none;
    width: 280px;
    height:308px;
    top: 100%;
    position: absolute;
    z-index: 598;
    list-style: none;
    margin: 0;
    padding: 0;
    background: rgba(0, 40, 58, 0.91);
    padding: 5px;
}

#SettingWrap li {
    width: 267px;
    height: 40px;
    line-height: 40px;
    vertical-align: middle;
    padding: 5px 10px;
    color: #9dd702;
}

According to this article , i write below code but don't work:

$("#SettingWrap").on("mousedown", function (e) {
    e.preventDefault();
});

正如@Mosh Feu在评论中所说，我在画布的click事件之前调用event.stopPropagation() ，它解决了我的问题。
