I have passed props through to different ponents and pages before but this has been through link or just added these to the ponent tag itself.

The issue I have here is that the redirect is not going through a link tag or in a ponent tag and instead I am simply using window.locatio.href ="whatever the url is".

I simply want to pass a variable through to this (I am technically doing a refresh in this situation so window.location.reload() could also work if it is possible).

How would I pass through a variable within this. When using express you can do fetch statements with an endpoint simialr to (might not be exact syntax) "./page${variableYouWant}" Then access sit in the express file using req.params.variableYouWant.

Is this possible to pass a variable this way and how would I then access it.

Here is the most important snippet of my code.

pageRelocator(mssg) {
    if (mssg.length < 35) {
      toast.info(`${mssg}`, {

        draggable: true,

        autoClose: 1500
      });
      window.location.href = "http://localhost:3000/pleted-assessment";
    } else if (mssg.length > 35) {
      toast.error(`${mssg}`, {

        draggable: true,

        autoClose: 1500
      });
//Here I would like to pass a variable
      window.location.href = "http://localhost:3000/user-questions";
    }
  }

EDIT--

ponentDidMount() {
    const search = this.props.location.mssg;
    alert(search); // returns the URL query String
    const params = new URLSearchParams(search);
    const IdFromURL = params.get("mssg");

    this.setState({
      questions: this.getItems(),
      WorkStations: this.getWorkStations()
    });
  }
  pageRelocator(mssg) {
    if (mssg.length < 35) {
      window.location.href = "http://localhost:3000/pleted-assessment";
    } else if (mssg.length > 35) {
      window.location.href = `http://localhost:3000/user-questions?mssg=${mssg}`;
    }
  }

Try using the URLSearchParams which defines utility methods to work with the query string of URL.so to attach a variable you would do

var id=5;
window.location.href = `http://localhost:3000/user-questions?id=${id}`;

and to retreive id from the URL you would do

const search = props.location.search; // returns the URL query String
const params = new URLSearchParams(search); 
const IdFromURL = params.get('id'); 

Hope this helps

If you want the data to be present even after refresh, try to pass the variable in params. http://localhost:3000/pleted-assessment?your_variable=value If you want to use this params value you can use window.location.search Using URLSearchParams you can get the each params you've sent with the URL.
