小程序綁定enter事件

<view class="search">
    <view class="search-container">
        <view class="search-left">
            <image class="search-image" src="/images/index/search.png" />
            <input class="search-input"  placeholder="請輸入你喜歡的商品" bindinput='watchSearch' data-keywords="{{keywords}}" bindconfirm='go_to_search_result'/>
        </view>
        <view class="search-btn" data-keywords="{{keywords}}" bindtap="go_to_search_result">搜索</view>
    </view>
</view>

bindconfirm

綁定后，就不需要點搜索按鈕了
