How to call when the function you want to use for the Render of React is a string

Asked 2 years ago, Updated 2 years ago, 47 views

There is a problem with Render processing of React.
There's a function called func1 that you call when you render.(Example: return(`<func1/>`).

For example, I would like to render the following JSON value from the string in funcName as the actual function name. What should I do?

 {funcName:"func1"} 

For the above values,

`return(<func1/>)`

I want to render as

I have considered many things myself, but even if I make it into a function or render it in a variable, I get an error.

The reason why I want to do this is that I am currently rendering with the following actions, but it is troublesome because I need to add an if statement every time I add a new func.

 if(funcName.func1!=null){
return `<func1/>`
} else if(funcName.func2!=null){
return `<func2/>`
}...Add if statement every time you add a function

That's all.If you know, please reply.

The JSX in React is the syntax sugar of React.createElement(...), so you can call React.createElement(...) directly instead of JSX.

For example, if func1 is a globally declared function,

React.createElement(window["func1"])

provides an object equivalent to <func1/>.
