这是代码
<select v-model="item[index]"
@change='select(item,index,event)'>
<option v-for="(t,j) in item.valarr" :value="t" :key="j">{{t}}</option>
</select>
sarr 值为 [{"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"A: 1","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}, {"label":"","valarr":["A: 1","B: 2","C: 3","D: 4","E: 5","F: 6","G: 7"]}]
我想在 select 里面设置默认值 假如说 label 的值有 'A: 1' ，这样就设为默认
在网上没找到太多相关的 希望有人能够指教一下

<select> 的 model 绑定了 item[index]，那么让这个状态有默认值就行了

<select v-model="selVal">
data: { selVal: 'whatever' } 这样 <select> 的默认值就被设定为 "whatever"。 |

Colorful OP @SilentDepth 这个我知道，现在理解了动态绑定是怎么样的了
