正确的方法（如果可能的话）将JSX代码存储到Javascript变量中

Question

I´ve written the following code using ReactJs´s JSX syntax:

import { Link } from 'react-router';

class SidebarMenuItem extends React.Component {

render() {

    var href = (this.props.submenu ? 'javascript:' : {<Link to="mod/admin" + this.props.link />};

    return ( 

        <a href={href} onClick={this.selected}>
            <i className={'fa ' + this.props.icon} />
            <span>{this.props.title}</span>
        </a>

    )
  }
}

But it seend that I cannot store a direct JSX code into a variable, as I got the following error:

Module build failed: SyntaxError: D:/9. DEV/client/components/App/SidebarMenuItem.js: Unexpected token, expected , (41:52)

> 41 |      var href = (this.props.submenu ? 'javascript:' : {<Link to="mod/admin" + this.props.link />};
     |                                                        ^

What is the correct way to store my Link component in the href variable ?

Answer 1

你只需编写普通的jsx，在你的情况下你需要删除jsx周围的括号，然后在“mod / admin”+ this.props.link部分周围包括括号，就像你在render方法中写一样。

var href = this.props.submenu ? 'javascript:' : <Link to={"mod/admin" + this.props.link} />

Answer 2

在JSX周围使用（）跨越多行

var href = this.props.submenu ? 'javascript:' : (<Link to="mod/admin" + this.props.link />);
