Random Character Case

[jscott21]

Is there any way to take a string in one text box and randomize the case of each character (Upper and Lower), then place it in a new text box?

Here is my function:

function calltext() {
regulartext = reg_text.length;
for (i=0; i<regulartext; i++) {
j = Math.ceil(Math.random(2));
if (j == 1) {
new_text += reg_text.charAt(i).toUpperCase;
} else if (j == 2) {
new_text += reg_text.charAt(i)toLowerCase;
}
}
}

Thanks for any and all help

Here is a rewrite of your code that will do it. You were nearly there. A few problems I fixed:

1) I simplified your random code. random(2) returns either 0 or 1, and works very well for this kind of thing. If it returns 1, it's true, otherwise it's false. You only need a simple if/else construct.

2. I changed all the variables that are only used inside the function to local vars (using the var) keyword, to help reduce side effects.

3. I made reg_text a parameter that is passed to the function.

4. I set a dynamic text field's contents to the results. This code assumes your dynamic text field has been named myTextField.

code:

---

function calltext(reg_text) 

{

  var len = reg_text.length;

  var new_text = '';

  for (var i=0; i < len; i++) {

    if (random(2)) {

      new_text += reg_text.charAt(i).toUpperCase();

    } else {

      new_text += reg_text.charAt(i).toLowerCase();

    }

  }

  trace(new_text); // test output

  return new_text;

}



myTextField.text = calltext('Hello how are you');
