vue @click的时候,第一次点击无效,第二次才有效果,点击两次才有效<select type="button" v-model="typhoonYear" @click="getselectYearByDistinct" @change="getTyphoonListByYear"> <option value="">--请选择--</option> <option v-for='item in typhoonYearList' :key="item.id">pw_ item </option> </select> <script> export default { name: "typhoon", data: function () { return { typhoonYear: '', //台风年份o typhoonYearList: [],//数据库中台风发生的年份 } }, /*根据年份获取当年的所有台风年份*/ getselectYearByDistinct:function() { //表格 // var _this = this; var option=this.typhoonYearList; this.$axios.get(request.selectYearByDistinct) .then(function (response) { var data=response.data; var item =1; for (item in data) { if(!option.includes( data[item])) { option.push( data[item]); }else { return data[item]; } } }) .catch(function (error) { window.console.log(error); }); }, 问题:结果第一次点击无效,第二次才出现效果。 解决办法: mounted() { this.getselectYearByDistinct();//在mounted()中添加这个方法,就解决了 }, </script> |
