Help me fix the code for binary to text translator

Hi experts,

I am developing one binary translator like this: https://www.gradecalculator.tech/binary-translator/

The confusion is only in javascript function. The code is given below that I used in my tool. I don't know what's wrong with the code but I get error in console like ($ is not a function). Please help me to solve this issue. Thanks in advance.

function BtoText()
{
  var bin = $("#bin").val();
  var i=$(".calc select")[0].selectedIndex;
  if( i==0 )
     bin = bin.match(/[0-1]{1,8}/g);
  else
     bin = bin.match(/[0-1]*/g).filter(function (el) {
        return el!="";
     });
  if( !bin ) return;
  len = bin.length;
  if( len==0 ) return;
  txt='';
  for(i=0; i<len; i++)
  {
     b = bin[i];
     code = parseInt(b,2);
     t = String.fromCharCode(code);
     txt += t;
  }
  $("#txt").val(txt);
}

You need to decide what the format of your input binary will look like. Will you force the input to be multiples of 8-bits? If your input is a character string of binary numbers at multiple of 8-bits long, then:

function Output=b2text(Input)%Input'010010000110010101101100011011000110111101110111'
Output=char(bin2dec(reshape(Input,8,[])')');
end
