weex踩坑记录（4）

1、weex中默认的css样式不要写：

display,
position: relative,

2、color属性都写全，不然爆出警告（这个可能跟项目的配置有关）
color: #fff; -> color: #ffffff;

3、align-self: center；的替换方案：
1、在元素的外层加一个div标签，然后对该div设置居中flex布局： justify-content: center; align-items: center
2、如果该元素有固定的宽度： margin-left: (750 - 元素的宽度) / 2

4、自定义slider的指引器

<slider class="banner-slider" auto-play="true" interval="3000" @change="getSliderIndex">
      <div v-for="(banner, index) in data.bannerList" :key="index" >
        <image class="banner-slider-image" @load="onImageLoad" :resize="data.effect === 2 ? 'cover' : 'contain'" :src="banner.src"></image>
        <text class="banner-slider-title">{{banner.title}}</text>
      </div>
      <!-- <indicator class="banner-slider-indicator" v-if="data.effect === 2 && data.bannerList.length > 1"></indicator> -->
    </slider>
    <!-- 自定义indicator -->
    <div class="custom-indicator-box">
      <div class="custom-indicator" :class="[index === currentSliderIndex ? 'custom-indicator-active': '']" v-for="(banner, index) in data.bannerList" :key="index"></div>
    </div>

.banner-slider-indicator {
  position: absolute;
  right: 10px;
  bottom: 0;
  height: 60px;
  item-size: 20px;
  item-color: #dddddd;
  item-selected-color: #ffffff;
}
.custom-indicator-box {
  position: absolute;
  right: 10px;
  bottom: 0;
  height: 60px;
  flex-direction: row;
}
.custom-indicator {
  width: 20px;
  height: 20px;
  border-radius: 10px;
  border-width: 1px;
  border-style: solid;
  border-color: #ffffff;
  background-color: transparent;
  margin-right: 5px;
}
.custom-indicator-active {
  background-color: #ffffff;
}
.banner-slider-title {
  width: 750px;
  position: absolute;
  left: 0;
  bottom: 0;
  padding: 0 80px;
  font-size: 20px;
  line-height: 32px;
  text-align: center;
  color: #ffffff;
  background-color: rgba(102, 102, 102, 0.8);
  overflow: hidden;
  text-overflow: ellipsis;
  lines: 1;
}

    onImageLoad (event) {
     ...
    },
    getSliderIndex (e) {
      this.currentSliderIndex = e.index
    }
