Correct syntax for loop

[wildred]

I have 3 layers on a page. When I click one I want to hide all 3 layers. The
function below calls another function (it works correctly) that hides them
all. The names of the layers are - layer1, layer2 and layer3. But my 'for
loop' syntax below is not working. What is the proper syntax to hide the
layers? Thanks a lot.

function hideAll() {
var i=0;
for (i=0;i<=2;i++)
{
HideContent('layer') + i;
}}

Wouldn't this execute these statements:
HideContent('layer') + 0;
HideContent('layer') + 1;
HideContent('layer') + 2;
?

Not having seen HideContent, I would have thought that you would want:
HideContent('layer' + 1);
HideContent('layer' + 2);
HideContent('layer' + 3);

If so, I think that the code should read:
function hideAll() {
for (var i=1;i<=3;i++)
{ HideContent('layer' + i); }
}

Thanks a lot, Trevor. Works great. This will really help my page
programming.

I think, you call HideContent function in wrong way. :)
Try this code.
So, hideAll calls HideContent 3 times and pass 3 params in such order:
'layer1', 'layer2' and 'layer3'.

function hideAll() {
for (var i=1;i<=3;i++)
{
HideContent('layer' + i);
}
}

For small numbers you might [in this NG] be forgiven for not doing a loop:

function hideAll() {
HideContent('layer1');
HideContent('layer2');
HideContent('layer3');
};
