Uni-app中Class綁定與Style綁定

爲了節約性能,咱們將Class與Style的表達式經過compiler硬編碼到uni-app中

支持語法和轉換效果以下:

Class支持語法:

1 <view :class="{ active: isActive }">111</view>
2 <view class="static" v-bind:class="{ active: isActive, 'text-danger': hasError }">222</view
3 <view class="static" :class="[activeClass, errorClass]">333</view>
4 <view class="static" v-bind:class="[isActive ? activeClass : '', errorClass]">444</view>
5 <view class="static" v-bind:class="[{ active: isActive }, errorClass]">555</view>

Style支持語法:

1 <view v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }">666</view>
2 <view v-bind:style="[{ color: activeColor, fontSize: fontSize + 'px' }]">777</view>

不支持Vue官方文檔:   Class與Style綁定中的classObject和styleObject語法.

此外還能夠用computed方法生成class或style字符串,插入到頁面中,

1 <template>
2     <!-- 支持 -->
3     <view class="container" :class="computedClassStr"></view>
4     <view class="container" :class="{active: isActive}"></view>
5     <!-- 不支持 -->
6     <view class="container" :class="computedClassObject"></view>
7 </template>
