我基于vue引导获得了以下选择代码:
<b-form-select v-model="selectedgroup" class="mb-3" @change="searchSubGroup()">
<option :value="null">Select a group</option>
<option v-for="group in groupItem" :value="group.id">
{{group.nome}}
</option>
</b-form-select>
当@change事件调用
searchSubGroup()
方法时,@ change事件将传递旧值selectedgroup
。示例:如果我首先单击值= 1的选项,则该方法将调用selectedgroup
作为null
,然后,如果我再次单击另一个值= 2的选项,该方法将调用selectedgroup
作为1。searchSubGroup(){
this.axios.get("http://chart.solutions/public/api/produto/subgroup/search/" + this.selectedgroup + "/").then(response => {
if (response.data.erro) {
//console.log("subgroup doesnt exist")
}else{
this.subGroupItem = response.data;
}
})
}
最佳答案
您应该调用不带括号的searchSubGroup
方法。这将自动将新选择的值传递给您的方法。
<b-form-select v-model="selectedgroup" class="mb-3" @change="searchSubGroup">
<option :value="null">Select a group</option>
<option v-for="group in groupItem" :value="group.id">
{{group.nome}}
</option>
</b-form-select>
然后,在您的方法中,您应该执行以下操作:
searchSubGroup(value){
this.axios.get("http://chart.solutions/public/api/produto/subgroup/search/" + value + "/").then(response => {
if (response.data.erro) {
//console.log("subgroup doesnt exist")
}else{
this.subGroupItem = response.data;
}
})
}
