How can I dynamically insert a variable string into a link tag using React and TypeScript?

I am just starting out with javascript and typescript, and I need to generate a link based on certain variables. I am currently facing an issue trying to insert that link into 

<a href="Some Link"> Some Text </a>

Both the "Some Text" and "Some Link" values are sourced from variables.

I have managed to fetch the "Some Text" from a variable 

<dd><a href="{thisDoesNotWork}">{someText}</a></dd>

However, I am struggling to make the href attribute work with a variable string as it is being taken literally. How can I make the href work with a variable string?

Providing more context:

Current typescript code:

return (
   <div>
      ....
      <dd><a href="hardCodedSomething">{someText}</a></dd>
   </div>
)

Desired behavior:

var someDynamicUrl = "somepath.com" + someId

return (
   <div>
      ....
      <dd><a href="someDynamicUrl">{someText}</a></dd>
   </div>
)

Answer №1

It seems like your current issue is more tied to react rather than typescript.

You're on the right track to getting it to work:

  • val needs to be changed to var
  • The value of the href attribute should be enclosed in curly brackets as well

Below is the updated code snippet:

var dynamicUrl = "somepath.com/" + someId;
var text = "your text";

return (
   <div>
      ....
      <dd><a href={dynamicUrl}>{text}</a></dd>
   </div>
);

Try using 'string' instead of 'String' if you are encountering issues. For more information, check out this link: Understanding the distinction between types String and string
