在rmarkdown文档中，如何在带有htmltools包的标记内使用HTML特殊字符？
如果我们在rmarkdown文档的r块中写这样的话
htmltools::tags$th("μ")
我们得到：
<th>&mu;</th>
而不是
<th>μ</th>
答案 0 :(得分：0)
你能解决这个问题吗？
gsub("amp", "", htmltools::tags$th("μ"))
<th>μ</th>
答案 1 :(得分：0)
const Login =(props:any) =>{
const [state, setState] = useState({
Email:'',
Password:''
});
const inputOnChange = (e:any) => {
setState({
...state,
[e.target.name]: e.target.value
})
};
useEffect(()=>{
const token = localStorage.getItem('Token');
if(token !== null) {
props.authTokenCheck()
}
// eslint-disable-next-line react-hooks/exhaustive-deps
},[localStorage.getItem('Token')]) ;
const loginButtonEvent = (e:any) => {
props.authLogin(state.Email, state.Password)
};
return(
<div>
{props.auth.isAuthenticated?
<div>
<h1>I am authenticated</h1>
<h2>{`${props.auth.isAuthenticated}`}</h2>
</div>:
<div>
<div>
{props.auth.loading?
<div><h1>Loading</h1></div>
:
<div>
<input placeholder={'Email Address'}
name={'Email'} onChange={(e)=>{inputOnChange(e)}}
type="text"/>
<input placeholder={'Password'}
name={'Password'}
onChange={(e)=>{inputOnChange(e)}}
type="password"/>
<button onClick={(e)=>{loginButtonEvent(e)}}>Login</button>
</div>
}
</div>
</div>}
</div>
};
const mapStateToProps = (state:any) =>({
auth: state.auth
});
const mapDispatchToProps = (dispatch:any) => {
return {
// dispatching actions returned by action creators
authLogin: (email:string,password:string) => dispatch(authLogin(email,password)),
authTokenCheck: () => dispatch(authTokenCheck()),
}
};
export default connect(mapStateToProps, mapDispatchToProps)(Login)
软件包为此提供了一个功能htmltools：
HTML结果为：
require(htmltools)
require(magrittr)
"μ" %>% HTML %>% (tags$th) %>% as.character %>% cat
