Help with dynamic field...

[rob88wells]

Hi,

Was wondering,
I have a dynamic text field, with contents: "yellow, seven, house, bird"
Is there an actionscript you know that will detect the commas and delete everything after it.

For example,

", bird" would be deleted, "yellow, seven, house" would remain.

And so on.


Thanks,

For this you need the slice and lastindexOf string functions. If you want to delete everything after the last comma

code:

---

str = "yellow, seven, house, bird";

str = str.slice(0, str.lastIndexOf(","));

Sorry,
I see now it's the variable of the dynamic text field.

It works great, thanks !

str's a variable name in this case, the code would work just as well if you exchanged it for platypus. it's just good programming code to make it clear what purposes your variables are serving

but make sure you don't name any variables with reserved words such as String or Number as these are built-in Flash objects and functions

Ok.

One more question,
Because the first word (Yellow) has no comma in front of it, it is not all deleted at once, it's deleted character by character.
Is there a way around this? Or do I have to put a comma infront of it?

maybe just a quick if statement to see if there are any commas

code:

---

if(str.indexOf(",") <> -1) {

    str = str.slice(0, str.lastIndexOf(","));

}else{

    str = "";

}
