Question

The problem statement is like this: I have a contract. On renewal on every month the contract name should append with renewal identifier. For example at beginning the name is myContract then on first renewal name should be myContract-R1, next renewal name should be myContract-R2 and so on.. On each renewal, the name should automatically change. So in Jquery how can I do this?

This is a JavaScript question, not a jQuery question. jQuery adds little to JavaScript’s built-in string manipulation.

It sounds like you want to take a string in the form “myContract” or “myContract-Rx” and have a function that appends “-R1” (if there’s no “-Rx” already) or increments the number that’s there.

There’s no shortcut for that, you have to do it. Here’s a sketch that works, I expect it could be optimized:

function incrementContract(name) {
  var match = /^(.*)-R([0-9]+)$/.exec(name);
  if (match) {
    // Increment previous revision number
    name = match[1] + "-R" + (parseInt(match[2], 10) + 1);
  }
  else {
    // No previous revision number
    name += "-R1";
  }
  return name;
}
