For Loop to search an array
I have a source text on another layer where a user can input values separated by semi-colon:
a = [10; 20; 30; 40]
I need to check this array to see if any value is above my maximum number (“cap”)
However, when I use a for loop expression, it’s only looking at the last number in my array and not considering if any other value is above my cap:
a = thisComp.layer(“Text_Input”).text.sourceText.split(“; “);
l = a.length;
cap = 100;
for (i=0; i<l; i++){
if(a[i] >= cap) “Fail”; else “Pass”
}
I feel like I’m missing something really obvious here.

You have a few issues here. The main one is the difference between AE seeing the text input as a string vs integers. To split it by “;” it needs to be a string. To compare it to 100, the numbers need to be integers. Also, you need closing braces within your if statement, and to call for an alert with your “pass” or “fail”. For a script, it’s like this:
var thisComp = app.project.activeItem;
var a = thisComp.layer(“Text_Input”).text.sourceText.value; //look at the value of the source text
var aString = a.toString(); //convert value to string
var aArray = aString.split(‘;’);//split it
var l = aArray.length;
var cap = 100;
for (i=0; i<l; i++){<=”” p=””></l;>
//convert the array values into integers as you cycle through them
if(parseInt(aArray[i]) >= cap) {
alert(“Fail”);
}else {
alert(“Pass”);
};
};
Expression version is below.

Sorry, just noticed you need this as an expression on another layer. It’s like this:
a = thisComp.layer(“Text_Input”).text.sourceText.value;
aString = a.toString();
aArray = aString.split(‘;’);
l = aArray.length;
cap = 100;
failCheck=[];
for (i=0; i<l; i++){
if(parseInt(aArray[i]) >= cap) {
failCheck.push(“Fail”);
}else {
failCheck.push(“Pass”);
};
};
failCheck;

Oh wow, I was way off base! Thanks so much.
For anyone who needs to use this, there is a small syntax error on the aArray = aString.split(‘:’), it should be “;”. Also the other “” are coming in as ” ” when you copy into Ae. But once swapped out it works perfectly!

Yeah, I’ve noticed the forum font swaps those quotations. I need to learn how to add the little code window to avoid that!
