<view class="container">

<input class='title' name='title' placeholder='{{titlePlaceholder}}' value='{{title}}'  ></input>

<textarea class='content' name='content' placeholder='{{contentPlaceholder}}' value='{{content}}'></textarea>

<view class='images' wx:for='{{images}}' wx:key="{{index}}" >

<view wx:if="{{item.index == -1}}">

<image class='image' src='{{item.url}}' bindtap='chooseImage' data-index="{{item.index}}"></image>

</view>

<view wx:else>

<image class='image' src='{{item.url}}' bindtap='delImagePlaceholder' data-index="{{index}}"></image>

</view>

</view>

</view>

这是我的自定义组件，如何在原生的form中获得，title和content的值？
