Question

Sorting the layers and using a loop

Hello,

I have such part of code. It is sorting me the layers in proper order.

My question is how to use a loop of existence of every layer for that ? "Check if such given layer exists, use the code. When it doesn't exist, go to the next layer" ?

 

"

var aLay = app.activeDocument.layers.getByName("tertiary");
aLay.zOrder( ZOrderMethod.BRINGTOFRONT);

var aLay = app.activeDocument.layers.getByName("secondary");
aLay.zOrder( ZOrderMethod.BRINGTOFRONT);

var aLay = app.activeDocument.layers.getByName("primary");
aLay.zOrder( ZOrderMethod.BRINGTOFRONT);

Thank you. They are working great.

 

I still have problems with these kind of loop.

For me it would be ideal if script checks if such layer exists, then bring it to front. When it doesn't exist, do nothing.

it would be ideal for me as well, but there isn't a command to check for layer existance

 

No, no, I needn't catch errors.

checking for errors is a way of telling if a layer exists

you can use a try/catch to trap errors

 

var idoc = app.activeDocument;
try {
var ilayer = idoc.layers.getByName('Layer 2');
// DO SOMETHING
alert(ilayer.name);
}
catch(e) {
// DO SOMETHING ELSE
alert(e);
}

Then next layer the same, and next and next...

 

These are only three example layers.

Loop thru layers and check if a named-layer exists; if so, bring to front; if not, check if a next named-layers exists:

 

 

for (var i = 0; i < activeDocument.layers.length; i++) {
 if (activeDocument.layers[i].name == "tertiary") {
   activeDocument.layers["tertiary"].zOrder(ZOrderMethod.BRINGTOFRONT);
 }
 if (activeDocument.layers[i].name == "secondary") {
   activeDocument.layers["secondary"].zOrder(ZOrderMethod.BRINGTOFRONT);
 }
 if (activeDocument.layers[i].name == "primary") {
   activeDocument.layers["primary"].zOrder(ZOrderMethod.BRINGTOFRONT);
 }
}

What do you mean by "proper order"?  Do you want the first-created to be topmost?  Or do you want them ordered by name ("primary" to be topmost)?

No, no, it is working nice now. It is sorting me the layers from the top in this order: primary, secondary, tertiary.

But when for example there is no layer "secondary", then the script crashes in that moment.
