Comparing Strings

[williamoc74]

Hi..

I'm trying to compare strings while using ethers. I've tried lots of different ways and I'm just not getting it, I know it's very basic but hopefully someone here can help me. :)

I'm taking data from transaction.data and calling it string 'ourData' . I'm converting it to a string 74 in length and calling it string 'ourNewData' . If 'ourNewData' is the same as 'inputData' (a string that I populate with my own data) I want my function foo() to run, if not, I want it to keep checking until it does match.

It just keeps running through the if statement as if it does match all the time.
I've tried different ways of storing the strings and checking them ,(===), booleens etc but nothing is working. I see alot of stuff about == vs === in javascript but whatever way I try it just won't do what I want.

This is the code..

<const init = function ()
{
const provider = new ethers.providers.WebSocketProvider(url);

provider.on("pending", (tx) =>
{
provider.getTransaction(tx).then(function (transaction)
{
const ourData = transaction.data;

  string = ourData;
  var length = 74;
  ourNewData = string.substring(0, length);
  
 const inputData = 12345...74;

  if((ourNewData) == (inputData)){
   foo();
  }
  else{  
   return;
  }
}

}
}>

Thanks..

Sorry. I don’t quite understand the problem you are trying to solve. Strings aren’t special in ethers…

Do you need quotes around your inputValue value? Otherwise it will just be a number?

Yeah it's a strange one. I figured out it something to do with the way I'm organising the data before comparing - nothing wrong with the compare.
I've moved on for now but thanks for your time ricmoo..
