这个处理 是根据 index 作为父节点 和 子节点/**一维数组处理成多维数组* Array 一维数组* curparent 父级id（父子关联字段）* nextson子级id（父子关联字段）*/multiChangeArray(Array , curparent , nextson) {let data = JSON.parse(JSON.stringify(Array ));data.forEach(item => {let son = data.find(res => res[curparent ] === item[nextson]);if (son) {item.children = item.children || [];item.children.push(son);} else {item.children = item.children || [];item.children.push({label: '555555555'});}});return [data[0]];},
