Looping through layers and setting them to visible

I'm trying to loop through the layers in an InDesign doc and set all of them to visible. This is to ensure that file collection occurs correctly.
I put together the following
var myDocument = app.activeDocument;
//make all layers visable
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible = false) {
myDocument.layers[i].visible = true;
};
};
This is excerpted from a larger script that automates the file collect, this is just the routine for the layers.
For context here's the actual script.
function Left(str, n){
if (n <= 0)
return "";
else if (n > String(str).length)
return str;
else
return String(str).substring(0,n);
}
function Right(str, n){
if (n <= 0)
return "";
else if (n > String(str).length)
return str;
else {
var iLen = String(str).length;
return String(str).substring(iLen, iLen - n);
}
}
if (app.documents.length != 0){
var myDocument = app.activeDocument;
var docName = myDocument.name;
var docName = Left(docName, String(docName).length-5)
//alert(docName);
var myFolder = new Folder ("~/Desktop/"+docName+"/");
//myFolder.create("Bob");s
/*new Folder ("~/Desktop/Collected/Hi-Res PDF/");
new Folder ("~/Desktop/Collected/RELEASE INFO/");*/
//make all layers visable
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible = false) {
myDocument.layers[i].visible = true;
};
};
myDocument.packageForPrint (myFolder,1,1,0,1,0,0,0);
var newFolder = new Folder ("~/Desktop/"+docName+"/RELEASE INFO/");
newFolder.create();
var inddFolder = new Folder ("~/Desktop/"+docName+"/Indesign Files/");
inddFolder.create();
var newFolder = new Folder ("~/Desktop/"+docName+"/IDML Files/");
newFolder.create();
//Export IMDL File
myDocument.exportFile(ExportFormat.INDESIGN_MARKUP, File("~/Desktop/"+docName+"/IDML Files/"+docName+".idml"), false);
//Move INDD File
//var myInddfile = File("~/Desktop/"+docName+"/"+docName+".indd");
//myDocument.changePath(File(inddFolder),false);
//Rip Low Res PDFs
var myPDFExportPreset = app.pdfExportPresets.item("CP3 Low Rez");
app.activeDocument.exportFile(ExportFormat.pdfType,
File("~/Desktop/"+docName+"/RELEASE INFO/"+docName+"_LR.pdf"), false, myPDFExportPreset);
//Now export the document. You'll have to fill in your own file path.
//app.activeDocument.exportFile(ExportFormat.pdfType, File("~/Desktop/"+docName+"_FILM/RELEASE INFO/"+docName+"_LR.pdf"), false);
var newFolder = new Folder ("~/Desktop/"+docName+"/Hi-Res PDF/");
newFolder.create();
//Rip Hi-Res PDF
var myPDFExportPreset = app.pdfExportPresets.item("Kern Hi Rez Print");
app.activeDocument.exportFile(ExportFormat.pdfType,
File("~/Desktop/"+docName+"/Hi-Res PDF/"+docName+"_HiRes.pdf"), false, myPDFExportPreset);
//Now export the document. You'll have to fill in your own file path.
//app.activeDocument.exportFile(ExportFormat.pdfType, File("~/Desktop/"+docName+"_FILM/Hi-Res PDF/"+docName+"_HiRes.pdf"), false);
myFolder.execute();
}
else{
alert("Please open a document and try again.");
}
Hopefully, when the script executes, all the layers will be set to visible then the file collect will occur.

Use triple equals in your if statement for strict equality. For instance:
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible === false) { // <-- Note the `===` instead of `=`
myDocument.layers[i].visible = true;
};
};
Or even better, you can change it to utilize the Logical NOT ! operator
for (i = 0; i < myDocument.layers.length; i++) {
if (!myDocument.layers[i].visible) { // <-- Change to this.
myDocument.layers[i].visible = true;
};
};
Note: Given your example, the conditional if statement is not actually necessary. You could simply do this instead:
for (i = 0; i < myDocument.layers.length; i++) {
myDocument.layers[i].visible = true;
};
Set everything to be visible
If you actually want to make everything visible - including; InDesign document layers and all page items on the sub-layer(s), then you'll need to do something like this example:
var myDocument = app.activeDocument;
// ...
function makeAllVisible() {
for (i = 0, max = myDocument.layers.length; i < max; i++) {
var currentLayer = myDocument.layers[i];
currentLayer.visible = true; // Make the top level layer visible.
// Make all sub layers visible,
// i.e. make all page items on the current layer visible.
var currentLayerPageItems = currentLayer.allPageItems;
for (x = 0, len = currentLayerPageItems.length; x < len; x++) {
currentLayerPageItems[x].visible = true
}
}
}
makeAllVisible(); // Invoke the function.
// ...

Illustrator scripting

I am writing a script for an active doc in Illustrator. The active doc already has the spot swatch for "LEAD" in it. All the paths I have to set and symbols need to be set to this swatch. I have worked my way around it by deleting the swatch then re-adding it to the doc. This works for all my paths and objects created. There are 3 symbols in the active doc that are being placed by scrip, that are already set to the spot swatch. When my script deletes the swatch it resets the symbol to 100% black process. Is there a way to pull the swatch from the active doc?All path items reqiure the leadSpotColor variable to set that color. The LEAD swatch already exist in the active doc. If i do not add the swatch remove line before hand it errors out, but the swatch remove line sets my symbols already in the active doc to 100% process black, and they also need to be set to the LEAD swatch.
if ( app.documents.length = "LEAD" ) {
swatchToDelete = app.activeDocument.swatches["LEAD"];
swatchToDelete.remove();
}
var leadSpot = doc.spots.add();
var leadSpotColor = new CMYKColor();
leadSpotColor.cyan = 0;
leadSpotColor.magenta = 0;
leadSpotColor.yellow = 0;
leadSpotColor.black = 100;
leadSpot.name = "LEAD";
leadSpot.colorType = ColorModel.SPOT;
leadSpot.color = leadSpotColor;
var leadSpotColor = new SpotColor();
leadSpotColor.spot = leadSpot;

Why would you want to delete the swatch if you can just edit it ?
var main = function(){
var doc,
leadClr, c;
if(!app.documents.length) return;
doc = app.activeDocument;
leadClr = getLeadColor(doc);
if ( leadClr===null ) {
var leadSpot = doc.spots.add();
var leadSpotColor = new CMYKColor();
leadSpotColor.cyan = 0;
leadSpotColor.magenta = 0;
leadSpotColor.yellow = 0;
leadSpotColor.black = 100;
leadSpot.name = "LEAD";
leadSpot.colorType = ColorModel.SPOT;
leadSpot.color = leadSpotColor;
var leadSpotColor = new SpotColor();
leadSpotColor.spot = leadSpot;
}
else {
c = leadClr.color.spot.color;
c.cyan = 0;
c.magenta = 0;
c.yellow = 0;
c.black = 100;
}
};
var getLeadColor = function(doc){
var clrs = doc.swatches,
n = clrs.length;
while (n-- ) {
if ( clrs[n].name=="LEAD" ) return clrs[n];
}
return null;
}
main();
I would recommend adding some prevention mechanism like ensure swatch is actually a spot prior to reach teh spot property.

First of all first line of your code is wrong
if ( app.documents.length = "LEAD" )
How you can compare length with string "LEAD", its should be a number and also in if statement we use conditional operator and what you are doing is assigning value in if statement.
Here is the script for LEAD spot, that will give you spot color if exist otherwise it will create new spot color with name "LEAD"
function main() {
var currentDocument;
var leadSpotColor;
if (!app.documents.length) {
alert("No document is open");
return;
}
currentDocument = app.activeDocument;
leadSpotColor = getLeadSpotColor(currentDocument);
applyColorToAllPath(leadSpotColor, currentDocument);
}
function getLeadSpotColor(currentDocument) {
try {
var leadSpotColor = currentDocument.spots.getByName('LEAD')
return leadSpotColor;
} catch (e) {
var color = new CMYKColor();
color.cyan = 0;
color.magenta = 0;
color.yellow = 0;
color.black = 100;
var newSpot = currentDocument.spots.add();
newSpot.name = "LEAD";
newSpot.colorType = ColorModel.SPOT;
newSpot.color = color;
var leadSpotColor = new SpotColor();
leadSpotColor.spot = newSpot;
return leadSpotColor;
}
}
function applyColorToAllPath(leadSpotColor, currentDocument) {
// Change code as per your requiremnt. I just handled for pathItems. You can similary for symbols.
var pathItems = currentDocument.pathItems;
for (var i = 0; i < pathItems.length; i++) {
pathItems[i].filled = true;
pathItems[i].fillColor = leadSpotColor;
pathItems[i].stroke = true;
pathItems[i].strokeColor = leadSpotColor;
}
}
main();

Basicprimitives org chart node preview working wrong

I successfully create a organizational chart with BasicPrimitives-orgChart but I have a problem with the node's preview when you do mouse hover.
Sometimes randomly gray "preview" node appears on the left of the screen.
Sometimes the preview shows correctly
But somethimes appear the gray node
My fucntion to chart create
function buildChart() {
var options = new primitives.orgdiagram.Config();
var jsonString = $("[id$=txhDat]").val();
var datos = JSON.parse(jsonString);
var arrayItem = [];
for (index = 0; index < datos.length; index++) {
var objUbica = datos[index];
var item = new itemUbica(objUbica.cve, objUbica.name, objUbica.parent, objUbica.index);
var itemFinal = new primitives.orgdiagram.ItemConfig(item);
arrayItem[arrayItem.length] = itemFinal;
}
options.items = arrayItem;
options.cursorItem = 0;
options.templates = [getTemplateUbica()];
options.onItemRender = onTemplateRender;
options.hasButtons = primitives.common.Enabled.True;
options.hasSelectorCheckbox = primitives.common.Enabled.False;
options.onButtonClick = function (e, data) {
switch (data.name) {
case "move":
$("[id$=]")
dialogMoveOp(data.context.cveUbica, data.context.ubica);
break;
}
};
jQuery("#divChart").orgDiagram(options);
}
Also this happend just after the first render I dont manipulate anything in the DOM.

Photoshop Javascript to get all layers in the active document

I'm sure it should be discussed before by Photoshop scripters. I write a solution as following. I think it's logically right, but the result is not correct. Anybody can help to check where's wrong in the code, or have ideas for this topic? I want to get all the layers in a document.
Code:
function getAllLayersInLayerSets(layerNodes) {
var retList = [];
for (var i=0; i<layerNodes.length; i++) {
if(layerNodes[i].layerSets.length > 0)
{
var tmp = getAllLayersInLayerSets(layerNodes[i].layerSets);
var j = (tmp == null) ? -1 : tmp.length-1;
while(tmp && j>=0)
{
retList.push(tmp[i]);
j--;
}
}
for(var layerIndex=0; layerIndex < layerNodes[i].artLayers.length; layerIndex++)
{
var layer=layerNodes[i].artLayers[layerIndex];
retList.push(layer);
}
}
return retList;
}
Many thanks for any help or discussion.

I know this is an old thread, but this might be useful for someone.
I was looking for a function that would get me all the ArtLayers in a Photoshop comp, including layers nested in groups. The above function was returning undefined, so I modified it and got it to work.
var doc = app.activeDocument;
var allLayers = [];
var allLayers = collectAllLayers(doc, allLayers);
function collectAllLayers (doc, allLayers){
for (var m = 0; m < doc.layers.length; m++){
var theLayer = doc.layers[m];
if (theLayer.typename === "ArtLayer"){
allLayers.push(theLayer);
}else{
collectAllLayers(theLayer, allLayers);
}
}
return allLayers;
}

Minor expansion on Ghoul Fool's post to only get all VISIBLE art layers in the active document. :P
// Get layers in a document
var sourceDocument = app.activeDocument;
var visibleLayers = [];
var visibleLayers = collectAllLayers(sourceDocument, visibleLayers);
// Print out total layers found
alert(visibleLayers.length);
// Recursively get all visible art layers in a given document
function collectAllLayers (parent, allLayers)
{
for (var m = 0; m < parent.layers.length; m++)
{
var currentLayer = parent.layers[m];
if (currentLayer.typename === "ArtLayer")
{
if(currentLayer.visible)
{
allLayers.push(currentLayer);
}
}
else
{
collectAllLayers(currentLayer, allLayers);
}
}
return allLayers;
}

To get all the layers (and sub layers) you have to have a recursive function
var allLayers = new Array();
var theLayers = collectAllLayers(app.activeDocument, 0);
function collectAllLayers (theParent, level)
{
for (var m = theParent.layers.length - 1; m >= 0; m--)
{
var theLayer = theParent.layers[m];
if (theLayer.typename != "ArtLayer")
{
allLayers.push(level + theLayer.name);
collectAllLayers(theLayer, level + 1)
}
}
}

function selectAllLayers() {
var desc29 = new ActionDescriptor();
var ref23 = new ActionReference();
ref23.putEnumerated(charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt'));
desc29.putReference(charIDToTypeID('null'), ref23);
executeAction(stringIDToTypeID('selectAllLayers'), desc29, DialogModes.NO);
}

Write arrays content in my page using javascript

I'm studying javascript for the first time and I've some doubt: I have two arrays; the first one contain the image of a person, the second one his personal informations (the arrays' length is the same because they contain the same number of people). I'd like to write the content in my page so print the image and the infos of the first user, then the image and the infos of the second and so on...
How can I do it?
this is the code:
function jsonCard()
{
var richiestaCard = new XMLHttpRequest();
richiestaCard.onreadystatechange = function()
{
if(richiestaCard.readyState == 4)
{
var objectcardjson = {};
window.arrayCard= []; //creazione dell'array che conterrà le cards
objectcardjson = JSON.parse(richiestaCard.responseText);
arrayCard = objectcardjson.cards; //the first array
}
}
richiestaCard.open("GET", "longanocard.json", true);
richiestaCard.send(null);
}
function jsonEntity()
{
var richiestaEntity = new XMLHttpRequest();
richiestaEntity.onreadystatechange = function()
{
if(richiestaEntity.readyState == 4)
{
var objectentityjson = {};
window.arrayEntity= []; //creazione dell'array che conterrà le entity
objectentityjson = JSON.parse(richiestaEntity.responseText);
arrayEntity = objectentityjson.cards; //the second array
}
}
richiestaEntity.open("GET", "longano.json", true);
richiestaEntity.send(null);
}
function displayArrayCards()
{
jsonCard();
jsonEntity();
var inizioTag = "<img src=";
var fineTag = "\>";
for(i = 0; i < arrayCard.length; i++)
{
...
}
}
I'd like to have the image and then the infos (for the first user), the image and the infos for the second and so on all included in a div.

Try something along the lines of
function displayArrayCards()
{
jsonCard();
jsonEntity();
var wrapper = document.getElementById('div you want to put all of these users into');
for(i = 0; i < arrayCard.length; i++)
{
var userDiv = document.createElement('div');
var cardImg = document.createElement('img');
img.src = arrayCard[i];
/** Set other attributes for img **/
var entityDiv = document.createElement('div');
entityImg.innerHTML = arrayEntity[i];
/** Set other attributes for div **/
userDiv.appendChild(cardImg);
userDiv.appendChild(entityDiv);
wrapper.appendChild(userDiv);
}
}
Honestly there are a lot of ways to do this. Above is simply what I would do.
