Script to Check if Parent Type is Master

Hello,

I'm using a script to resize objects in a document. Regarding primary text frames, the script edits both the frames present on the master pages and the occurrences on the linked pages. Therefore, the link is lost for position and size.

Is there a condition I could add to test whether the object's parent type is a master page, in order to target only these objects?

primaryTextFrame

If you want to check if Parent is "master":

and either by checking type of the parent directly - or parent of the parentPage.

One more thing - for pages - pageItems - is a collection of items that are "directly" on the page - allPageItems - is a collection of all items that are "directly" and "indirectly" on the page(s) - anchored and grouped.

Of course, each object have its own pageItems and allPageItems collections - that works the same way - "direct" and "all" childrens.

@Robert at ID-TaskerWere you thinking of something like this?

if (textFrames[Id].parent == '[object MasterSpread]') {
  // true
}

Yes.

But if your TF is anchored - parent will be Character - so you probably would need to ignore it as well.

Can you post the script. If I remember correctly the primary frame should not appear in the pages pageitem collection, that should work for you but we need to see what the script is exactly doing as well.

Hello @Manan Joshi

Below is the basis of the script. I removed the content from the loop, but in summary, each frame is resized to fit the page margins. I didn't apply the function to pageItems, but to textFrames and rectangles. Maybe this is my mistake?

function auto_size (collection) {
  for (Id = 0; Id < collection.length; Id++) {
      // Resize
  }
}

auto_size (app.activeDocument.textFrames);
auto_size (app.activeDocument.rectangles);

I could be reading it wrong, but I think @35626004 , wants to skip the text frames on the pages that are primary.

Yes, move only TFs on Master's - so overriden TFs on pages will still be linked "by location" with TFs on MasterPages.

Thank you @Robert at ID-Tasker and @rob day for your answers, I am studying them.

I'm having trouble understanding what everyItem() and getElement() imply regarding object access.

To expand a bit, I was happy with my script until I realized that the children of primary frames were no longer connected to their parent. The problem is that the script, in its current state, targets all frames, breaking parent-child links (as each is resized individually). Non-primary frames are not problematic because they are not accessible as child objects.

I'm not sure what approach to take to this problem. Below, I managed to collect all my master page items in an array.

var master = app.activeDocument.masterSpreads;
var frames = [];

for (var_1 = 0; var_1 < master.length; var_1++) {
  for (var_2 = 0; var_2 < master[var_1].pageItems.length; var_2++) {
    frames.push (master[var_1].pageItems[var_2]);
  }
}
