Select page range

The sample script below places emphasis on the dialog used to get the page range from the user. Run the script and then analyze the code. You should be able to apply much of this to your needs. Hope this helps.

try {

    //assumes document is open

    var docRef = app.documents.item(0);

    var maxPages = docRef.pages.count();

  //provide variable to hold user's response

  var userResponse = dialogWChoices ("Dialog Name", true, "Label here", maxPages);

    //enter call to function that processes all pages

    if (userResponse[0] == 0) {

        myProcess (docRef, 0, maxPages);

     } else {

         var minPageRef = userResponse[1] - 1;

         var maxPageRef = userResponse[2] - 1;

         myProcess (docRef, minPageRef, maxPageRef);

     }

} catch (e) {

  alert (e);

}

alert ("User entered " + userResponse[0] + " " + userResponse[1] + " " + userResponse[2]);

//function to process range of pages

function myProcess (docRef, minPageRef, maxPageRef) {

    var thisPage, thisFrame, docOffset;

   for (var i = minPageRef; i <= maxPageRef; i++) {

       thisPage = docRef.pages.item(i);

       docOffset = (thisPage.documentOffset) + 1;

    thisFrame = thisPage.textFrames.add({geometricBounds:[36, 72, 100, 300]});

    thisFrame.contents = "Hello page " + docOffset

   }

}

//function gets page range or "all" from user

function dialogWChoices (dlgName, cancelIt, dLabel, maxPages) {

    var userCancelled = false;

    var origValue = app.scriptPreferences.userInteractionLevel;

  //make sure that user interaction levels will allow a dialog

  app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;

  //create the dialog

  var dlgRef = app.dialogs.add({name:dlgName, canCel:cancelIt, label:dLabel});

  //add a column

  var dlgColumn1 = dlgRef.dialogColumns.add();

    var dlgColumn2 = dlgRef.dialogColumns.add();

    var dlgColumn3 = dlgRef.dialogColumns.add();

  //add widgets for first column

  dlgColumn1.staticTexts.add({staticLabel: "PageRange:"});

  //add widgets to second column

  var radioGroup = dlgColumn2.radiobuttonGroups.add();

    radioGroup.radiobuttonControls.add({staticLabel:"All", checkedState:true});

    radioGroup.radiobuttonControls.add({staticLabel:"Range", checkedState:true});

    //add widgets to third column; put reference into a variable

    var emptyRow = dlgColumn3.dialogRows.add();

    emptyRow.staticTexts.add ({staticLabel: ""});

    var inputRow = dlgColumn3.dialogRows.add();

    var firstField = inputRow.integerEditboxes.add({minWidth:36, minimumValue:1,maximumValue:maxPages});

    inputRow.staticTexts.add ({staticLabel: " thru "});

    var secondField = inputRow.integerEditboxes.add({minWidth:36, minimumValue:1, maximumValue:maxPages});

  //show the dialog and capture the result

  if (dlgRef.show() == true) {

        var firstVal = 0;

        var secondVal = 0;

        var selButton = radioGroup.selectedButton;

        if (selButton == 1) {

  var firstVal = firstField.editValue;

  var secondVal = secondField.editValue;

    }

  } else {

        userCancelled = true;

  }

       dlgRef.destroy();

       app.scriptPreferences.userInteractionLevel = origValue;

    if (userCancelled) {

       throw ("User Cancelled");

    }

  //destroy the dialog; script doesn't get here if user cancels

  return [selButton, firstVal, secondVal];
