Testing for Auto Leading and an alert

[timmysmuckers]

Hey everybody.

I would like to test with a script if a text layer is using Auto Leading and display an alert if it is not set to auto.

This is what I have now:

var doc = activeDocument 

var lay = doc.activeLayer

var textSize = lay.textItem.size

var textlayer = doc.activeLayer

if (lay.textItem.autoLeading = "false"){

     alert("Leading is set to a custom value of "+(activeDocument.activeLayer.textItem.leading) + ".")}

This works when something is set to a specific leading. But when it is set to Auto Leading I get this error.

So I know my "IF" or "VAR" needs to be reworked (probably the alert too just to clean it up), but I have run out of ideas.

First off, you need to set you if statement with a double equal sign "==", otherwise you're setting laytextItem.autoLeading to false. Use a try catch block. if it throws an error, then you know there is auto leading.

Thank you, Chuck. Always a huge help.

I changed the conditional to:

     if (lay.textItem.useAutoLeading == false){

          alert("Leading is set to a custom value of "+(activeDocument.activeLayer.textItem.leading) + ".")}
