Javascript string to variables

Let's say I have a javascript string formatted like:

"var1='hello'&var2='value2'&var3='value3'" - is there a way for me to parse that/evaluate it turn that string into actual variables?

Thanks!

Before we talk code - can you tell us what you want to do with the variables. There are different ways to solve this - if you explain your intention it will help to pinpoint what the right solution is.

I've got an app I'm writing that scans a barcode.  The barcode only can return text/a string - which I'm going to format as variables.  I need something that interprets the returned text - and then parses it out as the appropriate values.

You can do something like this
var input = "var1='hello'&var2='value2'&var3='value3'";
var data = parseData(input);
alert(data.var1);
alert(data.var2);
alert(data.var3);

function parseData(inp)
{
  var data = {};
  inp = inp.split('&');
  for(var i = 0; i < inp.length; i++) {
    var item = inp[i].split('=');
    data[item[0]] = item[1];
  }
  return data;
}

Open in new window

You can now access your variables like this

console.log(data->var1
