Extend width of TextFrames with the same geometricBounds

gistfile1.js

#include "doEx.jsx"
var s = app.selection[0].geometricBounds.toString().replace(/\.\d+/g, '');
doEx('textFrames').each(function () {
	if (this.geometricBounds.toString().replace(/\.\d+/g, '') == s) {
		this.geometricBounds = [
		this.geometricBounds[0], this.geometricBounds[1] - 50, this.geometricBounds[2], this.geometricBounds[3]]
	}
});

扩展如下：
逐一找出与(多个)所选对象相同位置及类别的对象，执行某种操作，比如：一同移动位置

#include "doEx.jsx"
var d = app.activeDocument;
doEx(app.selection).each(function () {
    var s = this.geometricBounds.toString().replace(/\.\d+/g, ''),
        str = this.toString(),
        type = eval('d.' + str.slice(8, 9).toLowerCase() + str.slice(9, -1) + 's');
    doEx(type).each(function () {
        if (this.geometricBounds.toString().replace(/\.\d+/g, '') == s) {
            this.geometricBounds = [
            this.geometricBounds[0] + 20, this.geometricBounds[1], this.geometricBounds[2] + 20, this.geometricBounds[3]]
        }
    })
});
