flash script question. - Tilted Forum Project Discussion Community

I'm making a flash for a website and i have a quick question that i cannot find anywhere. i know it's possible so maybe you can help?

i have 5 dynamic text box. each has a value loaded up in them. They are named
UVR_txt1 UVR_txt2 etc...

now my problem is that i need my action to tell my main text to = the UVR_txt that i need. how can i write it down so that it accepts the #?
example:

Code:

variable1 = 2
variable2 = uvr_txt(variable1).text

so it should look like:

Code:

variable2 = uvr_txt2.text

you see what i mean? am i forgetting something small here?

Note: I have zero experience in Flashscript, but...

Not every programming language has (easy) constructs for what you want. Basically you're trying to reference an object by name by joining 2 strings.

In other languages I've used one of 2 methods:

1. create an array (or linked list or whatever) with the objects in question.
2. construct the name of the object (string3=string1+string2) then use a GetObjectByName(string3)

Whichever method is applicable depends on Flashscript, but as I said, I've never programmed in Flash.

At least this post bumps your thread back up. Hope it helps

thanks for the reply. The reason i asked is because i know for sure theres a way to do this because i did it a few times at work 2-3years ago. so it shouldn't be that hard for me to get it but i just don't remember.

It's very difficult to transform a string into an array indexing command, which is what you're basically trying to do.

If all else fails, couldn't you just hard code it, since you only have 5 boxes?

Code:

if (variable1 == 1)
   variable2 = UVR_txt1.text
else if (variable1 == 2)
   variable2 = UVR_txt2.text
else if (variable1 == 3)
   variable2 = UVR_txt3.text
else if (variable1 == 4)
   variable2 = UVR_txt4.text
else if (variable1 == 5)
   variable2 = UVR_txt5.text

Sure, it's not the generic solution, but it works for five textboxes.

hmm. that works for not i guess.

but i'm sure there was a way to do this in the dynamic instance name to somehow say it's uvr_txt#... but isn't there a way to say: uvr_txt(variable).text? i was sure it was doable somehow. maybe it's [ ] or with some sort of other technique?
i will use your idea for now Jinn. thanks!

Did a little research, and Flash script actually supports this kinda of dereferencing. Kinda unique, actually.

There's two ways to do what you're talking about. You can either use the array indexing brackets [] or the eval() command.

Their documentation gives:

eval("piece" + x);

If you did

Code:

variable2 = eval("UVR_txt" + variable1).text

it would dynamically create the variable name.

Similarly, you can use the bracket notation to do it:

Code:

 variable2 = UVR_txt[variable1].text;

Where variable1 is the UVR_txt that you want the main text box to get

AH!!!! thank you so much!! i knew it was simple like that! i guess i just used the wrong search word in google.

this will make my life easier now!
