How to move some group items to another layer in Javascript for Illustrator?

[hongliangc41190231]

I'm working on a script to move some group items to another layer automatically using Javascript for Illustrator 2020. I can't find much script samples. Anyone can help? Thank you!

This snippet would move the first page item of "BACK TEXT" layer to the top of "Base" layer. Maybe this will get you started.

var aDoc = app.activeDocument;
var backText = aDoc.layers['BACK TEXT'].pageItems[0];
backText.move(aDoc.layers['Base'], ElementPlacement.PLACEATBEGINNING);

Use "ElementPlacement.PLACEATEND" to move it to the bottom of the target layer.

Hi,

The following snippet will help tomove the selected item to layer with name "Layer 2". This will work only if selected item is a groupItem. 

var aDoc = app.activeDocument;
if (app.selection.length) {
    var _selectedItem = app.selection[0];
    if (_selectedItem.typename == 'GroupItem') {
        try {
            var _layer = aDoc.layers['Layer 2'] //Assuming layer with name Layer 2 exists
            _selectedItem.move(_layer, ElementPlacement.PLACEATBEGINNING);
        } catch (e) {
            alert("Layer with name 'Layer 2' doesn't exists");
        }
    } else {
        alert("Please select groupItem");
    }
}
