Comparing text with javascript

[Corby Logue]

So I’ve made a little headway, or at least I understand a little better what’s going on.

I’ve got a var called myFile for the text file.

Then I create a var for the text and use ‘readIn()’. So suppose line one in my external my text document is “Once upon a time”

var text;
text = myFile.readln();

if (text == "Once")
DS ++;


Nothing happens, because the text variable is assigned the value of the entire line of text (“Once upon a time”).

So is there a way to be able to check just a word or even a single character from the text value?

Yes, I am going to answer my own questions. I promise I’m googling furiously before I ask… It’s just I keep googling.

Anyway… “text.charAt(0);” is what I needed.

This would be one way to count the number of “$” characters:

text.split(“$”).length-1

Different problem but same project… Not sure I understand why I’m not getting the behavior I think I should be getting:


var myComp = app.project.activeItem
var selLayers = myComp.selectedLayers;
var myMarker = selLayers[0].property("Marker");
var curMarker = myMarker.keyValue(i+1);

for (i=0; i < 4; i++){

alert(i + " " + curMarker.comment);

}


Wasn’t getting what I wanted, so I set up the alert to tell me what the script was doing.

Anyway, the alert value for “i” counts up like it should (0… 1… 2… 3… ), but the comment is always the comment at the 5th marker (there is no marker 0, so I add one to it)?

Why is it not cycling through (e.g. first returning the comment at the first marker, second returning the comment at the second marker, etc.)?

Got it… But I thought this was where I started.

Anyway, this: “var curMarker = myMarker.keyValue(i+1);”

Needs to be inside the loop. I could have sworn, that’s where I started, but I kept getting an error when running the script.

Okay… on to the next obstacle as I feel my way around in the low light!
