Javascript string to variable

[CroCrew]

Hello Everyone,

First let me say thanks for the help. Now for the question…

What I am trying to do is have a few declared variables where their names share the same common first part and have a unique second part. Then within a function I pass in the second part of the variable’s name and concatenate that with the first part to alert the value of that variable. Below is my code.

Again thanks for your help~


[HTML]<script language="JavaScript">
var LocalOne=’Hello’;
var LocalTwo=’Wow’;
var LocalThree=’Bye’;

function ShowVar(SecondPart)
{
alert(['Local'+SecondPart].value);
}
</script>[/HTML]

hi ...

have a look at the following example ... it assumes that the vars are global:

var LocalOne = 'Hello';
var LocalTwo = 'Wow';
var LocalThree = 'Bye';
 
function ShowVar(SecondPart) {
    alert(window['Local' + SecondPart]);
}
 
ShowVar('One');

kind regards

Can I also set a new value to the variable using..

window['Local' + SecondPart] = “Cool”;


Thanks~

     var LocalThree=’Bye’;
 
     function ShowVar(SecondPart)
     {
          alert(window['Local' + SecondPart]);
          window['Local' + SecondPart] = 'Cool';
     }
</script>

you answered your question already for yourself :) that works:

var LocalOne = 'Hello';
var LocalTwo = 'Wow';
var LocalThree = 'Bye';
 
function ShowVar(SecondPart) {
    window['Local' + SecondPart] = 'test';
    alert(window['Local' + SecondPart]);
}
 
ShowVar('One');
 
// to see for sure that it works:
alert(LocalOne);
 

kind regards
