反应路由器 - 在新选项卡上打开链接并重定向到主页

Question

Using React Router 4.2

My attempt is to open a new tab upon clicking on a navigation link and at the same time be redirected to the site homepage.

ie: Navigation bar: clicking on Policies

Even though the code bellow behaves as the requirements above: Is this the advisable way to go about it? Aiming to learn best practices here on Routes.js.

 //Routes.js
 import HandbookDoc from './policies.pdf'
 ...

 <Route 
   path="/registration/policies" 
   component={() => window.open(`${HandbookDoc}`,'_blank').then(window.location= '/')} 
 />

....

 //Navigation.js (using react-router-bootstrap)
  <NavDropdown eventKey={3} id="formId" title="Registration">
     <LinkContainer to="/registration/financial-aid">
        <MenuItem eventKey={3.1}>Financial Aid</MenuItem>
      </LinkContainer>
      <LinkContainer to="/registration/policies">
        <MenuItem eventKey={3.2}>Policies</MenuItem>
      </LinkContainer>
  </NavDropdown>

Answer 1

You don't need to create a new route for the thing you are trying to achieve. You could add an onClick handler to the MenuItem like this:

  <NavDropdown eventKey={3} id="formId" title="Registration">
     <LinkContainer to="/registration/financial-aid">
        <MenuItem eventKey={3.1}>Financial Aid</MenuItem>
      </LinkContainer>
      <LinkContainer 
        to="/">
        <MenuItem onClick={this.handlePoliciesClick} eventKey={3.2}>Policies</MenuItem>
      </LinkContainer>
  </NavDropdown>

And then in same component add the handler:

handlePoliciesClick = () => {
  window.open(HandbookDoc, '_blank');
}

Remember to import your HandbookDoc .
