(1)eg1

<view class="artList">
    <block v-for="(item,index) in artList" :key="index">

改为:

    <icon class='iconfont uc-liebiao'></icon>

1.2 scroll-view

(1)eg1

<!-- 通过点击方式(选项卡的方式代码负责且应用卡)切换分类(高效简单)  掌握css动态样式追加小技巧 -->
<view class="grace-header-cate">
    <scroll-view class="grace-tab-title grace-center" scroll-x="true" id="grace-tab-title">
        <view v-for="(cate,index) in categories" :key="index" :data-cateid="cate.cateId" :data-index="index" 
            :class="[cateCurrentIndex == index ? 'grace-tab-current' : '']" @tap="tabChange">{{cate.name}}
        </view>
    </scroll-view>
</view>

2. 基础内容

2.1 icon

请参考uni-app组件使用注意中的icon的使用说明部分。

2.2 text

3. 表单组件

3.1 button

<button type="primary" form-type="submit">添加</button>

3.3 form

(1)eg1

<!-- 输入区 -->
<form @submit="submit">
    <view class="inputArea">
        <view class="addImg" @tap="addImg">+图片</view>
            <view class="addText">
                <textarea name="artText" maxlength="-1" v-model="inputContent" placeholder="请输入文本"></textarea>
                <button type="primary" form-type="submit">添加</button>
            </view>
    </view>
</form>

3.4 input

• value :输入框的初始内容
• placeholder :输入框为空时占位符(引用国际化文本问题)
• name : 该属性的作用,uni-app官网无该属性
• v-model :动态绑定数据
• @input:当键盘输入时，触发input事件，event.detail = {value}
• @blur:输入框失去焦点时触发，event.detail = {value: value}
  (1)eg1

<input type="text" v-model="title" placeholder="请输入标题"/>

(2)eg2

<input type="text" class="weui-search-bar__input" :placeholder="T_D.keyword" placeholder-style="color:#e2e2e2" v-model="keyword"/>

(3)eg3

<input type="text" class="weui-search-bar__input" :placeholder="T_D.keyword" v-model="keyword" @blur="inputBlur" @input="inputTyping" />
<view class="weui-icon-clear" v-if="keyword.length > 0" @tap="clearInput">
    <icon type="clear" size="14"></icon>
</view>

(4)eg4
小程序:

<view class="weui-cell__bd">
     <input class="weui-input" type="text" placeholder="{{T_D.pleaseEnterGroupName}}" name="name" value="{{name}}">{{name}}</input>
 </view>

修改语法:

<view class="weui-cell__bd">
    <input class="weui-input" type="text" :placeholder="T_D.pleaseEnterGroupName" name="name" :value="name">{{name}}</input>
</view>

备注:input 为单标签,值只能写在里面.继续修改:

<view class="weui-cell__bd">
    <input class="weui-input" type="text" :placeholder="T_D.pleaseEnterGroupName" name="name" :value="name"></input>
</view>

双向绑定:v-model和:value的效果一致.

<view class="weui-cell__bd">
    <input class="weui-input" type="text" :placeholder="T_D.pleaseEnterGroupName" name="name" v-model="name"></input>
</view>

3.6 picker

• mode :
• :range :mode为 selector 或 multiSelector 时，range 有效
• :value :value 的值表示选择了 range 中的第几个（下标从 0 开始）
• @change :value 改变时触发 change 事件，event.detail = {value: value}
• :range-key :当 range 是一个 Array 时，通过 range-key 来指定 Object 中 key 的值作为选择器显示内容
  (1)eg1

<picker @change="bindPickerChange" :value="index" :range="array">
        <view class="uni-input">{{array[index]}}</view>
</picker>

(2)eg2

<!-- 选择分类 -->
<view class="art-cate">
    <view>文章分类</view>
    <view class="">
        <picker mode="selector" :range="caties" @change="cateChange">
            <view>{{caties[currentCateIndex]}}</view>
        </picker>
    </view>
</view>

3.6 picker-view

(1)eg1

<modal title="{{T_D.pleaseChoosePosition}}" hidden="{{modalHidden}}" confirm-text="{{T_D.confirm}}" cancel-text="{{T_D.cancel}}" bindconfirm="modalBindaconfirm" bindcancel="modalBindcancel">
       <picker-view indicator-style="height: 50px;border-top:1px solid green;border-bottom:1px solid green;" style="width: 100%; height: 200px;text-align:center;" range="{{positionArray}}" value="{{value}}" bindchange="bindChange">
              <picker-view-column>
                      <view wx:for="{{positionArray}}" wx:key="{{item.id}}" style="line-height: 50px">{{item.text}}</view>
              </picker-view-column>
      </picker-view>
</modal>

改为:

<modal :title="T_D.pleaseChoosePosition" :hidden="modalHidden" :confirm-text="T_D.confirm" :cancel-text="T_D.cancel" @confirm="modalBindaconfirm" @cancel="modalBindcancel">
    <picker-view  indicator-style="height: 50px;border-top:1px solid green;border-bottom:1px solid green;" style="width: 100%; height: 200px;text-align:center;" :value="value" @change="bindChange">
        <picker-view-column>
            <view v-for="(item,index) in positionArray" :key="item.id" style="line-height: 50px">{{item.text}}</view>
        </picker-view-column>
    </picker-view>
</modal>

备注:语法修改完成后,运行时列表内容不显示,只有一个空的列表架子.
modify1:

<modal :title="T_D.pleaseChoosePosition" :hidden="modalHidden" :confirm-text="T_D.confirm" :cancel-text="T_D.cancel" @confirm="modalBindaconfirm" @cancel="modalBindcancel">
    <picker-view  indicator-style="height: 50px;border-top:1px solid green;border-bottom:1px solid green;" style="width: 100%; height: 200px;text-align:center;" :value="value" @change="bindChange">
        <picker-view-column>
            <view class="item" v-for="(item,index) in positionArray" :key="item.id">{{item.text}}</view>
        </picker-view-column>
    </picker-view>
</modal>

.item{
    line-height: 50px;
    height:50px !important;
}

备注:style提取出来后,列表内容成功显示,但change事件异常,列表无法正常滑动.
modify2:

<modal :title="T_D.pleaseChoosePosition" :hidden="modalHidden" :confirm-text="T_D.confirm" :cancel-text="T_D.cancel" @confirm="modalBindaconfirm" @cancel="modalBindcancel">
    <picker-view v-if="!modalHidden" indicator-style="height: 50px;border-top:1px solid green;border-bottom:1px solid green;" style="width: 100%; height: 200px;text-align:center;" :value="value" @change="bindChange">
        <picker-view-column>
            <view class="item" v-for="(item,index) in positionArray" :key="item.id" style="line-height: 50px">{{item.text}}</view>
        </picker-view-column>
    </picker-view>
</modal>

注意:添加 v-if="!modalHidden" 所有问题都解决.

3.11 textarea

<textarea :value="item.content" placeholder="" v-model="artList[index].content"></textarea>

<textarea name="artText" maxlength="-1" v-model="inputContent" placeholder="请输入文本"></textarea>

4. 导航-navigator

<!-- 文章内容区 -->
        <view class="grace-news-list">
            <block v-for="(item,index) in artList" :key="index">
                <!-- 一张图 -->
                <navigator v-if="item.art_content.length < 3" open-type="navigate" :url="'../info/info?artid=' + item.art_id">

                </navigator>
            </block>
        </view>

5. 媒体组件

5.3 image

• src:图片资源地址
• mode:图片裁剪、缩放的模式
• lazy-load:图片懒加载
  (1)eg1

<image :src="item.content" :data-index="index" mode="widthFix" @tap="removeImg"/>

(2)eg2

<!-- 文章内容区 -->
        <view class="grace-news-list">
            <block v-for="(item,index) in artList" :key="index">
                <!-- 一张图 -->

              <progress percent="{{item.use_time}}" stroke-width="3" />
        </view>
 </view>

修改语法:

<view class="weui-progress">
    <view class="weui-progress__bar">
        <progress :percent="item.use_time" stroke-width="3" />
    </view>
</view>
