I used the following TreeWalker as a template from this post https://stackoverflow.com/a/37178130/7102491 and modified it to skip the element 'script', to prevent certain pages like a google search from breaking to no avail. Does anyone know how I can change the code to prevent breaking certain pages? Thanks.
var replaceArry = [
[/b/gi, 'better'],
[/Terms of service/gi, 'Términos y condiciones'],
[/Privacy policy/gi, 'Privacidad'],
// etc.
];
var numTerms = replaceArry.length;
var txtWalker = document.createTreeWalker (
document.body,
NodeFilter.SHOW_TEXT,
{ acceptNode: function (node) {
//-- Skip whitespace-only nodes
if (node.nodeValue.trim() && node.parentNode.nodeName != 'SCRIPT')
return NodeFilter.FILTER_ACCEPT;
return NodeFilter.FILTER_SKIP;
}
},
false
);
var txtNode = null;
while (txtNode = txtWalker.nextNode () ) {
var oldTxt = txtNode.nodeValue;
for (var J = 0; J < numTerms; J++) {
oldTxt = oldTxt.replace (replaceArry[J][0], replaceArry[J][1]);
}
txtNode.nodeValue = oldTxt;

I can't perform multiple delette from my listbox although I made the listbox mutiselect Why ??
I need your help . You can see the full Script down there.
(function(){
$.win = new Window("palette");
var win = $.win;
win.orientation = "column";
win.alignChildren = ["center", "top"];
win.spacing = 10;
win.margins = 16;
var listbox1 = win.add("listbox", undefined, undefined, { name: "listbox1", multiselect: true, columnTitles: "Max", showHeaders: true });
listbox1.preferredSize.width = 136;
listbox1.preferredSize.height = 208;
var button1 = win.add("button", undefined, undefined, { name: "button1" });
button1.text = "Search";
var button2 = win.add("button", undefined, undefined, { name: "button2" });
button2.text = "Delete";
win.show();
var myNewArray = [];
button1.onClick = function Search() {
var compsArray = new Array();
var myProj = app.project;
myNewArray = [];
listbox1.removeAll();
for (var i = 1; i <= myProj.numItems; i++) {
if (myProj.item(i) instanceof CompItem) {
myNewArray = compsArray[compsArray.length] = myProj.item(i);
listbox1.add("item", myNewArray.name);
}
}
}
button2.onClick = function deletecomps() {
for (var s = 1; s <= app.project.numItems; s ++) {
if ((app.project.item(s) instanceof CompItem) && (app.project.item(s).name.match(listbox1.selection))) {
myComp = app.project.item(s);
break;
}
}
app.project.item(s).remove ();
}
})();
You can see an image to clarify the script in AE
Your problem is that listbox1.selection in line 34
if ((app.project.item(s) instanceof CompItem) && (app.project.item(s).name.match(listbox1.selection))) {
is an array, and you're trying to match it to a string returned by app.project.item(s).name which is never going to match.
Also, what are you trying to achieve with the lines
myComp = app.project.item(s);
break;
Here's the onClick function, but it works. It loops through the selection, and looks for a matching project item, based on the text of the listbox matching the comp's name. This is dangerous, because identical comp names would create false positives. I strongly suggest you don't use this technique in production code, because it will definitely cause problems for your users.
Also I'd turn the part wherre you populate the list into a separate function, and call it after you click delete, so that the list is refreshed, because at the moment the list stays the same, even after the comp is deleted.
button2.onClick = function deletecomps() {
for (var b= 0; b < listbox1.selection.length; b++){
for (var s = 1; s <= app.project.numItems; s ++) {
if ((app.project.item(s) instanceof CompItem) && (app.project.item(s).name.match(listbox1.selection[b].text))) {
app.project.item(s).remove ();
}
}
}
}
In google docs one can easily add headings and link to them from inside of the document. But when the heading text changes, the link text does not change.
Is there a way to change that behavior or update the link text automatically?
I know it is about 1 1/2 years, but maybe this will help. I have had the exact same problem and wrote a function that will update all the links to the headings in a document. Since I could not find any built-in functions or add-ons, the only way was to script it.
Some things to consider:
This needs a current table of contents to work. If you don't have (or do not want) a TOC, you can insert one, run that function and delete it afterwards. Also, I have only tested it with a TOC that contains page numbers.
It will update ALL texts of links to headings in the document. However, links to everything else remain untouched.
Please use at your own risk (maybe try it out in a copy of your document). I have tested it, but the testing could have been more thorough. Also, this is my first in scripting Docs.
Paste this in the Script editor of your doc and run replaceHeadingLinks. Links that the script could not update (because they link to a heading that does not exist anymore) will be output in the console.
function replaceHeadingLinks() {
var curDoc = DocumentApp.getActiveDocument();
var links = getAllLinks_(curDoc.getBody());
var headings = getAllHeadings_(curDoc.getBody());
var deprecatedLinks = []; // holds all links to headings that do not exist anymore.
links.forEach(function(link) {
if(link.url.startsWith('#heading')) {
// get the new heading text
var newHeadingText = headings.get(link.url);
// if the link does not exist anymore, we cannot update it.
if(typeof newHeadingText !== "undefined") {
var newOffset = link.startOffset + newHeadingText.length - 1;
// delete the old text, insert new one and set link
link.element.deleteText(link.startOffset, link.endOffsetInclusive);
link.element.insertText(link.startOffset, newHeadingText);
link.element.setLinkUrl(link.startOffset, newOffset, link.url);
} else {
deprecatedLinks.push(link);
}
}
}
)
// error handling: show deprecated links:
if(deprecatedLinks.length > 0) {
Logger.log("Links we could not update:");
for(var i = 0; i < deprecatedLinks.length; i++) {
var link = deprecatedLinks[i];
var oldText = link.element.getText().substring(link.startOffset, link.endOffsetInclusive);
Logger.log("heading: " + link.url + " / description: " + oldText);
}
} else {
Logger.log("all links updated");
}

Here is my code :
for (var j in albums){
var album_images = albums[j].images
var l = album_images.length
for ( var i = 0; i < l; i++ ) {
var image = album_images[i]
Like.findOne({imageID : image._id, userIDs:user._id}, function(err,like){
if(like){
console.log(i)
//console.log(albums[j].images[i])
//albums[j].images[0].userLike = true;
}
})
}
}
Here I have albums, and I am populating images of album
So album variable contains all the albums and inside them their images will also be there in a array
I want to add a extra field (userLike) in each images.
Problem here is all the time the value of the i is 3 (that is the number of images in a album (album_images.length) - for the time being I have only one album)
I think the problem could be because the callback of Like.findOne calls only when all the loops has finished executing (just a guess).
How can I make it work so that I will get all the loop values in console.log(i) ?
Thanks in advance
I prefer using forEach:
albums.forEach(function(album, j) {
var album_images = album.images;
album_images.forEach(function(image, i) {
Like.findOne(...);
});
});
Just a tip: instead of performing a findOne for each image, you may consider using $in.
Alternatively you could define a function in order to have a scope where the variable doesn't change.
...
handle_album_image = function(image, i, j) {
Like.findOne({imageID : image._id, userIDs:user._id}, function(err, like){
if(like){
console.log(i)
//console.log(albums[j].images[i])
//albums[j].images[0].userLike = true;
}
})
}
for ( var i = 0; i < l; i++ ) {
var image = album_images[i]
handle_album_image(image, i, j)
}
I need to offer a feature which allows InDesign users to select a page range in an InDesign document and create a new document out of those pages. This sounds simple, but it isn't...
I have tried many different ways of doing this but they have all failed to some degree. Some methods put all pages in a single spread (which sometimes makes InDesign crash). The best I've been able to do (see code below) still has problems at the beginning and the end (see screenshots below):
The original document:
The new document:
The question: How can I create a new document out of a subset of another document's pages (in InDesign using ExtendScript) without having the problems shown in the screenshots?
note: The behavior of the script is quite different in CS5.5 and CS6. My question concerns CS6.
The second screenshot was obtained by applying the following code to the document shown in the first screenshot:
CODE
var firstPageName = { editContents: "117" }; // This page number is actually entered by the user in an integerEditbox
var lastPageName = { editContents: "136" }; // This page number is actually entered by the user in an integerEditbox
var sourceDocument = app.activeDocument;
var destDocument = app.documents.add();
destDocument.importStyles(ImportFormat.paragraphStylesFormat, new File(sourceDocument.filePath + "/" + sourceDocument.name), GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
destDocument.importStyles(ImportFormat.characterStylesFormat, new File(sourceDocument.filePath + "/" + sourceDocument.name), GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
destDocument.viewPreferences.horizontalMeasurementUnits = sourceDocument.viewPreferences.horizontalMeasurementUnits;
destDocument.viewPreferences.verticalMeasurementUnits = sourceDocument.viewPreferences.verticalMeasurementUnits;
destDocument.documentPreferences.facingPages = sourceDocument.documentPreferences.facingPages;
destDocument.documentPreferences.pageHeight = sourceDocument.documentPreferences.pageHeight;
destDocument.documentPreferences.pageWidth = sourceDocument.documentPreferences.pageWidth;
destDocument.documentPreferences.pageSize = sourceDocument.documentPreferences.pageSize;
var sourceSpreads = sourceDocument.spreads;
var nbSourceSpreads = sourceSpreads.length;
var firstPageFound = false;
var lastPageFound = false;
var i;
var newSpreadNeeded;
var currentDestSpread;
for (i = 0; !lastPageFound, i < nbSourceSpreads; ++i) {
newSpreadNeeded = true;
var sourcePages = sourceSpreads[i].pages;
var nbSourcePages = sourcePages.length;
var j;
for (j = 0; !lastPageFound, j < nbSourcePages; ++j) {
if (sourcePages[j].name === firstPageName.editContents) {
firstPageFound = true;
destDocument.documentPreferences.startPageNumber = parseInt(firstPageName.editContents); // We want to preserve page numbers
}
if (firstPageFound) {
// Copy this page over to the new document.
var firstInNewSpread = false;
if (newSpreadNeeded) {
currentDestSpread = destDocument.spreads.add();
newSpreadNeeded = false;
firstInNewSpread = true;
}
var newPage = sourcePages[j].duplicate(LocationOptions.AT_END, currentDestSpread);
var k;
for (k = 0; k < newPage.index; ++k) {
currentDestSpread.pages[k].remove();
}
}
if (sourcePages[j].name === lastPageName.editContents) {
lastPageFound = true;
}
}
}
destDocument.spreads[0].remove();
I was hacking around and came up with this little script. Although it approaches the problem from the opposite direction, it seems to work fine here. Also, I'm still running in InDesign CS5, but maybe it will work for you. Hopefully I got the gist of your question?
This will extract pages 3 through 5 into a separate document:
var doc = app.activeDocument;
var newFilePath = doc.filePath + "/subset_" + doc.name;
var newFile = File(newFilePath); // Create a new file path
doc.saveACopy(newFile); // Save a copy of the doc
var newDoc = app.open(newFile); // Open the copy
var firstPageNum = 3; // First page number in the range
var lastPageNum = 5; // Last page number in the range
var firstPage = newDoc.pages[firstPageNum-1];
var lastPage = newDoc.pages[lastPageNum-1];
// Remove all text from the last page in the range to the end of the document
var lastPageFrames = lastPage.textFrames.everyItem().getElements();
for (var i=0; i < lastPageFrames.length; i++) {
var frame = lastPageFrames[i];
var parentStory = frame.parentStory;
var lastFrameInsert = frame.insertionPoints.lastItem();
var lastStoryInsert = parentStory.insertionPoints.lastItem();
var textAfter = parentStory.insertionPoints.itemByRange(lastFrameInsert,lastStoryInsert);
textAfter.remove();
};
// Remove all text from the beginning of the document to the first page in the range
var firstPageFrames = firstPage.textFrames.everyItem().getElements();
for (var i=0; i < firstPageFrames.length; i++) {
var frame = firstPageFrames[i];
var parentStory = frame.parentStory;
var firstFrameInsert = frame.insertionPoints.firstItem();
var textBefore = parentStory.insertionPoints.itemByRange(0,firstFrameInsert.index);
textBefore.remove();
};
// Remove the pages that aren't in the range
var allPages = newDoc.pages.everyItem().getElements();
for (var i=0; i < allPages.length; i++) {
var page = allPages[i];
if (i < firstPageNum || i > lastPageNum) {
page.remove();
}
};
I'm trying to create a simple chrome extension using the following google RSS reader sample,
http://code.google.com/chrome/extensions/samples.html#597015d3bcce3da693b02314afd607bec4f55291
I can add links in the pop-up window that open tabs, but not from the feeds themselves.
Looping through the items in the feed, grabbing title tags and link tags, I want the title to link the the appropriate sites
var entries = doc.getElementsByTagName('item');
var count = Math.min(entries.length, maxFeedItems);
for (var i = 0; i < count; i++) {
item = entries.item(i);
// Grab the title for the feed item.
var itemTitle = item.getElementsByTagName('title')[0];
if (itemTitle) {
itemTitle = itemTitle.textContent;
} else {
itemTitle = "Unknown title";
}
// Grab the link for this feed item
var itemLink = item.getElementsByTagName('link')[0];
if (itemLink) {
itemLink = itemLink.textContent;
} else {
itemLink = "Unknown link";
}
var title = document.createElement("a");
title.className = "item_title";
title.innerText = itemTitle; //display title in iframe
title.addEventListener("click", titleLink); // should open link when clicking on title, but does not.
}
// -------------------------------------------------------------------
// Show |url| in a new tab.
function showUrl(url) {
// Only allow http and https URLs.
if (url.indexOf("http:") != 0 && url.indexOf("https:") != 0) {
return;
}
chrome.tabs.create({url: url});
}
function moreStories(event) {
showUrl(moreStoriesUrl);
}
function titleLink(event) {
showUrl(itemLink);
}
Any thoughts on why this is not working.
If I replace title.addEventListener("click", titleLink); with title.addEventListener("click", moreStories); each title will link to moreStories, I cannot get each title to link to itemLink.
Thanks
Its a bit hard to answer your question without the whole code, but Ill give it a shot ;)
First up, titleLink() isnt going to work because itemLink isnt known. When you create title (the link) you should of attached it to that...say title.href=itemLink then in tiltleLinks you could access that href with showUrl(event.currentTarget.href)
Also did you fix the error in that example?...if not then change frameLoaded to....
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var clssName = links[i].className;
if (clssName != "item_title" && clssName != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
If you still have probs could you attach the whole code so I can see what your doing and Ill give you a hand.
Thank you very much for your help.
code title.href=itemLink and code showUrl(event.currentTarget.href) was exactly what I needed.
For completeness, here is the full code,
<script id="iframe_script">
function reportHeight() {
var msg = JSON.stringify({type:"size", size:document.body.offsetHeight});
parent.postMessage(msg, "*");
}
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var class = links[i].className;
if (class != "item_title" && class != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
