添加核心代码如下:
this.data.push({ type: [{ value: '选项1', label: 'in' }, { value: '选项3', label: 'out' }], value:[{ value: '选项1', label: 'CSV' }, { value: '选项3', label: 'TSV' }], parameter:'', default:'', description:'', isDelete:false, });
删除核心代码如下:
/*遍历数组,然后根据选中的状态获取对应的下标,然后进行删除*/ for (let i = 0;i<this.data.length;i++){ let obj = this.data[i]; if (obj.isDelete){ this.data.splice(i,1); i-- } }
全部代码如下:

效果图如下:
