I' am a newbie in Rust programming. I'am learning webassembly. I have created a form which accepts two string and I want them concatenated and show the concatenated result in the html page. For academic interest I want my concatenation logic to reside in Rust. Can I get some help on how to do Form POST with Javascript to Rust library and receive a response back.

var a=document.getElementById("a1").value;
var b=document.getElementById("a2").value;
const result=wasm.concat(a,b);
alert(result);
document.getElementById("re").value=result;
});
