el-select使用方法及遇到数据回显的坑

< el-select v-model = " temp . lang " class = "filter-item" placeholder = "Please select" >

< el-option v-for = " item in langs " :key = " item . value " :label = " item . label " :value = " item . value " />

</ el-select >

 

langs: [{

value: '1' ,//这里注意值为字符型，须要与 temp . lang的值类型保持一致，不然不会正常回显

label: '中文'

},

{

value: '0' ,

label: '英文'

}

],

这里 注意值value为字符型，须要与 temp . lang的值类型保持一致，不然不会正常回显
