It's really hard to explain but I want to use the value of 2 variables, n use those 2 variables values to name another variable:
VarA="Goodness gracious!";
VarB="Var";
VarC="A";
VarD=VarB+VarC;
alert(VarD);
Instead of the alert popping up and saying "VarA" I want it to say "Goodness gracious!"...
NOTE: IF YOU CAN HELP ME WITH THIS PROBLEM THEN THAT IS ALL I WILL NEED -- THE REST WON'T BE NEEDED
Now to be more exact with what I'm trying to do... I want to:
- Create variables and set a unique message as their value
IE:
var DT_A="PACKAGE A INCLUDES THIS N THAT";
var DT_B="PACKAGE B INCLUDES THAT N THIS";
var DT_C="PACKAGE C INCLUDES THOSE N THESE";
var DL_A="PACKAGE A CAN BE FOUND HERE";
var DL_B="PACKAGE B CAN BE FOUND HERE";
var DL_C="PACKAGE C CAN BE FOUND HERE";
- Then I wanna make an option box that allows you to choose A, B, or C
- And 2 buttons next to the drop-down-menu that say [details] and [download]
- When I click the details button I want to pop an alert with the appropriate DT_ message
- When I click the download button I want to pop an alert with the appropriate DL_ message
IE:
packX=getElementByID('select1');
alert("DT_"+packX);
- Now I already can get what I want done the long simple way (using if commands) but I want to learn a cleaner way...
1) I DO NOT want to use more than 1 or 2 'if' commands meaning I don't want to do something like tell the [detail] button 'if the selected value in the drop down menu is A, then-> alert(DT_A)'
2) I would rather have 1 alert(); line in the command and have it use a variable, and to have that variable set to the proper value prior to the alert.
3) I want to set the value to each of the message variables seperately to organize and make it easier to add more...
-- You don't have to make it similar to my idea at all since my idea didn't work --
BTW: In my example it may not seem like I'm trying to do the same thing mentioned above but maybe you can see where I'm going wrong
