Question

我想在一行下面输入以下内容。有可能吗？

 `import SellerAdaptor from '../adaptors/sellers';
  import UserAdaptor from '../adaptors/user';
  import ShopEarnAdaptor from '../adaptors/shop_earn';
  import ProductAdaptor from '../adaptors/product';
  import JobAdaptor from '../adaptors/job';
  import OrderAdaptor from '../adaptors/order';
  import NotificationAdaptor from '../adaptors/notification';
  import CategoryAdaptor from '../adaptors/category';
  import AdminAdaptor from '../adaptors/adminAdaptor';`

Answer 1

否。

解构将使您可以从一个模块中导入许多值。

您不能一次导入多个模块。

典型的模式是使用../adaptors/index导入所有模块，然后导出它们：

import SellerAdaptor from './sellers';
import UserAdaptor from './user';
// etc
export { SellerAdaptor, UserAdaptor, etc };

那么您将能够：

import { SellerAdaptor, UserAdaptor, etc } from "../adaptors/index";

Answer 2

要能够写<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"> <xsl:output method="xml" encoding="UTF-8" indent="yes"/> <xsl:template match="/"> <xsl:for-each select="root/row[name='name1'] | root/row[name='name2']"> <xsl:variable name="filename" select="concat('output/',name,'.xml')" /> <xsl:result-document href="{$filename}" method="xml" encoding="iso-8859-1"> <xsl:for-each select="/"> <xsl:element name="topic"> <xsl:value-of select="."/> </xsl:element> </xsl:for-each> </xsl:result-document> </xsl:for-each> </xsl:template> </xsl:stylesheet>，它要放在import { A, B, C } from 'myPackage'上，并且要如何写。

如果它们是不同的文件，则无法执行。如果您有一个myPackage文件adaptors，其中包含export个不同的模块，则可以使用解构来编写导入文件。

Answer 3

您可以执行以下操作：

import SellerAdaptor from '../adaptors/sellers';
import UserAdaptor from '../adaptors/user';
import ShopEarnAdaptor from '../adaptors/shop_earn';
import ProductAdaptor from '../adaptors/product';
import JobAdaptor from '../adaptors/job';
import OrderAdaptor from '../adaptors/order';
import NotificationAdaptor from '../adaptors/notification';
import CategoryAdaptor from '../adaptors/category';
import AdminAdaptor from '../adaptors/adminAdaptor';


export {
    SellerAdaptor,
    UserAdaptor,
    ShopEarnAdaptor,
    ProductAdaptor,
    JobAdaptor,
    OrderAdaptor,
    NotificationAdaptor,
    CategoryAdaptor,
    AdminAdaptor
}

然后您可以按如下所示导入

import { SellerAdaptor, UserAdaptor} from './<filename>'
