Interface data and processing methods

	
		
		<----------------------------------------------->
		数据处理
			console.log(res.data.data)
			let fenji = res.data.data
			_this.jidurange = fenji.map((item, index) => ({
    
    
			  text: item.year,
			  value: index + 1,
			  children: item.children.map((child, childIndex) => ({
    
    
			    text: child.name,
			    value: parseFloat(`${
      
      index + 1}.${
      
      childIndex + 1}`),
			    cjsysid: child.sysid
			  }))
			}));


	

Data processing after selection to get the selected value

	changejidu(e){
    
    
		console.log(e.detail.value)
		const selec = e.detail.value[1].text
		 const matchedObject = this.jidurange.find(obj =>
		   obj.children.find(fruit => fruit.text === selec)
		 );
		const matct = matchedObject.children.find(obj => obj.text === selec);
		 console.log(matct);  //  选中的值
	}
