Javascript function help

Question

Can someone please look at this javascript function and tell me tell me what I am doing wrong? I want to pass in 4 variables. I know very little javascript.

Thanks.

  function chg(back,front,left,right)
  {
      return test("div#post", "#" + "back", "#" + "front", left, right);
  }

---

Here is the onload file

window.onload = function() {
  function chg(back,front,left,right)
  {
      return test("div#post", "#" + "back", "#" + "front", "left", "right");
  }
}

Answer 1

Nothing is syntactically wrong that I can see.

• Did you mean back instead of "back"? ( same with front )
• Is there a test function defined in an outer scope? What does it return?
• Are the 4 arguments being populated?
• Can you provide more code?

Answer 2

You have done nothing wrong syntactically. However, two of your input arguments (back and front) are never used - you are putting the words "back" and "front" in a string literal, so those arguments are never used. Functionally, it's impossible to say. What is test()? Is it another function declared elsewhere? If so, it would be helpful to see that one too.

Answer 3

For all intents and purposes, my code and your code do the exact same thing. Maybe this will help?

  function chg(back,front,left,right)
  {
      var result;

      //Pass left & right to the test function
      result = test("div#post", "#back", "#front", left, right);

      //Do something with back & front....
      //What?... I have no idea.

      return result;
  }
