以下以采购申请单例子举例三级子表。实际以开发的为准

业务对象

建立三级对象

业务对象设计

采购申请表


采购申请明细


供货商明细信息


表单管理

在表单中

拖入自定义组件 配置相关组件名组件路径

表单脚本中:

Object.assign(JForm,{
  //加载事件
  onLoad:function(form){              
    form.$refs.dynamicForm.$refs.formItemcgsqmx[0].$refs["formField"].$refs.elTable.$on('row-click',(row, column, event)=>{
      form.$refs.dynamicForm.$refs['formItemsupplier'][0].$refs.formField.$children[0].setRow(row)
    })
    const cgsqmxData =  form.getData('cgsqmx')
    if(cgsqmxData &&cgsqmxData.length>0){
      form.$refs.dynamicForm.$refs['formItemsupplier'][0].$refs.formField.$children[0].setRow(cgsqmxData[0])
    }

  }
});
