<avue-input v-model="newbusinessname" @change="changeBusinessname" type="tree" :dic="businessnameList"/>
data() {
return {
a:'',
newbusinessname:'',
businessnameList:[],
}
}
changeBusinessname(){
this.$message.warning(this.businessname)
},
之前没做处理前，当change改变时，信息提示总是出现两次。后来在data里加个变量存储change值，然后方法里修改如下，顺利解决。
changeBusinessname(){
if(this.a==this.businessname){
}else{
this.a=this.businessname
//这里放change该执行的事件
this.$message.warning(this.businessname)
}
},
