I got some problem about AE JavaScript;

Hi everyone, I'm new to AE js, and I wonder How do I get the color value/ or set value of fill color for the text layer.

I tried so many times but failed...

thanks

You should check out the expression language section of the help menu. Colors are determined with an array with four vapes. The value range is from 0 to 1 with as many decimal points as you like. The values describe the Red, Green, Blue and Alpha channel value for a color. For example adding this to an expression for fill color gives you 50% gray: [.5, .5, .5, 1] 

You can find the color values for elements in your comp panel by observing the info panel. Set the display to decimal:

Then sample a color and you'll get the values to type in the array:

Thanks for your answer sincerely, I want to get that RGBA value into a JavaScript array automatically,,,so I need a JavaScript expression to get that RGBA value. like var aColorValue = **********,,,

You need to explain exactly what you are trying to do. You can drive color that can be animated with an expression. I don't understand what you want to accomplish or where you are going with javascript. After Effects and After Effects Scripting are related to javascript but are separate and distinct. After Effects is used to create video and that's all. Please explain in detail what you are trying to do.

Hi Kevin,

maybe this is the answer I want that time;

var layer = app.project.activeItem.layer(1);                                        //get an textLayer

var textLayerDocument = layer.property("Source Text").value;                        //get fill color value

textLayerDocument.fillColor = [0.5, 0.5, 0.5];                                      //stort fill color value to [0.5, 0.5, 0.5] for textDocument object

layer.property("Source Text").setValue(textLayerDocument);                          //set textDocument value for textLayer "Source Text" property;
