a very simple question?!

Hello,

No doubt this is simple but I cannot see how to do it ...

I have a variable called situation_numbe r with a series of values 1,
2, 3 etc.

I would like to have a series of variables situation-1, situation-2
etc where the numbers 1 and 2 come from the situation_numbe r variable.

How do I create situation-1 etc such that the situation_)numb er
variable is used?

Thanks

Probably the best way to loop through them is to create the variables a
members of an Array, then loop through the array. It allows you to add
more elements and use them very easily - see showVars0().

Another method is to create all the variables as globals and access them
using square bracket notation and the window object - see showVars1():

for (var i=0; i<n; ++i){
alert( window['situation-' + i] );
}

But that is not good programming practice - the global space should not
be crowded with junk that need not be there - see showVars1().

Yet another way is to use eval - see showVars(2).
<script type="text/javascript">

// Using an array
function showVars0()
{
var sit = ['sit one','sit two','sit three'];

for (var i=0, j=sit.length; i<j; ++i){
alert( 'Array: ' +sit[i] );
}
}
showVars0();

// Using global variables
function showVars1()
{
sit1 = 'sit one';
sit2 = 'sit two';
sit3 = 'sit three';

for (var i=1; i<4; ++i){
alert( 'Global: ' + window['sit'+i] );
}
}
showVars1();

// Using eval
function showVars2()
{
var sit1 = 'sit one';
var sit2 = 'sit two';
var sit3 = 'sit three';

for (var i=1; i<4; ++i){
alert( 'Eval: ' +eval('sit'+i) );
}
}
showVars2();

</script>


Thanks

You may well be right Zoe - I'm going round quite a few circles these
days!

Have got this one sorted now!
