<select class="form-control" @change="inputChange(item.id,postObj[item.id])" v-model.trim="postObj[item.id]" :class="{'successBorder':exStatus[item.id]==1&&postObj[item.id]!=''&&item.required==1}">
<option value="">请选择</option>
<option :value="littleitem" :label="littleitem" v-for="littleitem in item.exDefaultValue" :key="littleitem">{{littleitem}}</option>
</select>
The revised code is such that the original drop-down box at the end ios options, in addition to select the outside, are not displayed, and then observed a moment please choose and dynamic loading option What is the difference, that is, the value of dynamic loading only bound label, the label did not write the middle option value, then, in the iphone mobile phone, these dynamic option value did not show up, but actually exists, then add the option tag values in the middle, on the show, write it down, hoping to help you
