I can't figure this one out:
I have a variable "myString"
The string myString may not contain any other character the a-z and 0-9
Let's say myString = "23-b" or "23.b" then I want to generate an error. 23b is ok.
I tried several thing like this:
valid = "0123456789abcdefghijklmnopqrstuvwxyz"
if (myString.indexOf(valid) == -1) {
bCheck = false
} else {
bCheck = true
}
I know this works fine in javascript, but I can't get it to work in Flash.
Any ideas on how to solve this one are welcome.

I have a feeling that it's looking for the entire valid string variable.
You'll either need to make a loop and go through the valid var or put each letter in an array and go through that:
Code:
for (var i=0; i<=valid.length; ++i) {
if (myString.indexOf(valid[i]) == -1) {
bCheck = false;
} else {
bCheck = true;
}
}
I haven't tested this but you get the idea.

DAMMIT! the forum removes some characters - doesn't work anyway. OK, try this:
Code:
valid = "0123456789abcdefghijklmnopqrstuvwxyz";
for (var i=0; i<=valid.length; ++i) {
currLett = valid.substring(i,i+1);
if (myString.indexOf(currLett) == -1) {
bCheck = false;
} else {
trace(currLett + " is OK");
bCheck = true;
}
}

*sigh* Sorry - made a real mess of that. Actually tried it out now and this works:
Code:
myString = "ababababaasddsffghghfb";
//myString = "a.babababaasddsffghghfb";
valid = "0123456789abcdefghijklmnopqrstuvwxyz";
for (var i = 0; i<=myString.length; ++i) {
//trace(currlett);
currLett = myString.substring(i, i+1);
if (valid.indexOf(currLett) == -1) {
//trace(currLett + " NO");
bCheck = false;
} else {
//trace(currLett + " is OK");
bCheck = true;
}
}
Leon (hopefully for the last time)

Thanks, I'll try this in the morning in my actual code and I'll let you know.
