Delete and Load Funcions not working in ListBox Script UI

[M.Hasanin]

Hi Experts

its just very tiny tool for saving GREP Queries, previously @Manan Joshi  helped me in creating it , now i add a title using multi columns lisbox in script UI so every grep query to be saved with its own title!, i  try to change tha code , i succeeded only in modifying inserting and saving function but i stucked in the Load and Delete functions, i still learning javascript so i get stucked from time to time! , i apperciate any help to make those functions works and thanks in advance :

var w = new Window ("dialog");
var myList = w.add ("listbox", undefined, " ",
{numberOfColumns: 2, showHeaders: true, columnTitles: ["GREP Name", "GREP Formula"]});

//MyListSize
myList.maximumSize.height = 1000;
myList.maximumSize.width = 1000;
myList.minimumSize.width = 1000;

//GREP Name
var StaticaName = w.add("statictext", undefined,"GREP Name");
StaticaName.alignment = "Left";
var myname = w.add ("edittext");
myname.active = true;
myname.characters = 100;

//GREP Formula
var StaticaGREP = w.add("statictext", undefined,"GREP Formula");
var input = w.add ("edittext");
StaticaGREP.alignment = "Left";
input.active = false;
input.characters = 100;

//-----------------------------------------------------------------------------------//
//Buttons Group 1
//-----------------------------------------------------------------------------------//
var gqmButtonGroup1 = w.add ('group {orientation: "row"}');
gqmButtonGroup1.alignChildren = "fill";
//GQMButtonGroup1.alignment = "stack";
//------------------------------------------------------------------------------------//
var inserttxt = gqmButtonGroup1.add ("button", undefined, " Insert GREP Query", {name: "Insert"});
var del = gqmButtonGroup1.add ("button", undefined, " Delete GREP Query", {name: "Delete"});
var gqmButtonGroup2 = w.add ('group {orientation: "row"}');
gqmButtonGroup2.alignChildren = "fill";
//GQMButtonGroup2.alignment = "stack";
var load = gqmButtonGroup2.add ("button", undefined, " Load GREP Queries", {name: "Load"});
var savelist = gqmButtonGroup2.add ("button", undefined, " Save GREP Queries", {name: "Save"});

//insert item Button
inserttxt.onClick = function () {
    insert_item (myList, myname.text);
    //insert_item (myList, input.text);
    input.text = "";
    input.text = "";
    input.active = true;
}

//delete selected item
del.onClick = function () {  
    // remember which line is selected
    var sel = myList.selection[0].index;
    for (var i = myList.selection.length-1; i > -1; i--)
    myList.remove(myList.selection[i]);

    // select a line after deleting one or more items
    if (sel > myList.items.length-1)
    myList.selection = myList.items.length-1;
    else
    myList.selection = sel;
}

function insert_item (list_obj, new_item) {
    if (list_obj.find (new_item) == null) {
    var stop = list_obj.items.length;
    //w.add(myList);
    var i = 0;
    while (i < stop && new_item > list_obj.items[i].text)
    i++;
    with (list_obj.add ("item", new_item, i)){
        subItems[0].text = input.text;
        }
    }
}

//Saving the List in the Same path of Indesign file (must before Show Command)
savelist.onClick = function () {
    //Define path and file name
    var filePathMinusExtension = app.activeDocument.fullName.fsName.substr(0, app.activeDocument.fullName.fsName.lastIndexOf("."));
    var writeFile = File(filePathMinusExtension + "_GREP_Queries.txt");
    writeFile.encoding = 'UTF-8';
    writeFile.open('w');
	var content = ""
	for(var i = 0; i < myList.items.length; i++)
        content += myList.items[i].toString() +","+ myList.items[i].subItems[0].toString() + "\r"
    writeFile.write(content);
    writeFile.close();
    alert("Done, File Saved in Same InDesign Document Location", "Alert!");
}

//Load List Items and Show them
load.onClick = function () {
    //Remove old list items
    myList.removeAll()
    var filePathMinusExtension = app.activeDocument.fullName.fsName.substr(0, app.activeDocument.fullName.fsName.lastIndexOf("."));
    var ReadFile = File(filePathMinusExtension + "_GREP_Queries.txt");
    if (ReadFile.exists) {
        try {
            ReadFile.open("r");

            while (ln = ReadFile.readln()) {
                myList.add("item", ln);
            }
            //Close the file
            ReadFile.close();
            alert("Done, the GREP Queries Loaded");
            return true;
        }
        catch (errOpen) {
            alert("Error. The GREP Queries file could not be opened!");
            return false;
        }
    }
    else{
        alert("The GREP Queries file could not be found!");
        return false;
    }
}

w.show ();

Maybe you should provide a more global explanation of what you are trying to achieve. Having code is great but without the big picture, we can only shoot in the dark.

What about screenshots/images of what you have now vs what you want to achieve? Once that is clarified, suggesting code edits will be more meaningful.

Thanks @Loic.Aigon for your reply, here is a screen shot to clarify concept, see here (the yellow buttons) are attached with the funciton (onClick) those Buttons linked to funcitons (Delete Grep Query) not working also (Load Grep Queries) not working also

so this function not working (Delete GREP Query) :

//delete selected item
del.onClick = function () {  
    // remember which line is selected
    var sel = myList.selection[0].index;
    for (var i = myList.selection.length-1; i > -1; i--)
    myList.remove(myList.selection[i]);

    // select a line after deleting one or more items
    if (sel > myList.items.length-1)
    myList.selection = myList.length-1;
    else
    myList.selection = sel;
}

also this function not working (Load GREP Query) :

//Load List Items and Show them
load.onClick = function () {
    //Remove old list items
    myList.removeAll()
    var filePathMinusExtension = app.activeDocument.fullName.fsName.substr(0, app.activeDocument.fullName.fsName.lastIndexOf("."));
    var ReadFile = File(filePathMinusExtension + "_GREP_Queries.txt");
    if (ReadFile.exists) {
        try {
            ReadFile.open("r");

            while (ln = ReadFile.readln()) {
                myList.add("item", ln);
            }
            //Close the file
            ReadFile.close();
            alert("Done, the GREP Queries Loaded");
            return true;
        }
        catch (errOpen) {
            alert("Error. The GREP Queries file could not be opened!");
            return false;
        }
    }
    else{
        alert("The GREP Queries file could not be found!");
        return false;
    }
}

these functions need to be modified to work with multi columns listbox, i hope this clear and thanks again for help

Hi All

Now i discovered a solution to remove the items from the list box from trail from error, and it works! for removing item and subitem :

//delete selected item 
del.onClick = function () {
     //Remove Items
     myList.remove(myList.selection.text);
     myList.remove(myList.selection.subItems[0].text);
}

Thanks alot friends! , i spent some time to squeez my mind and i figured it out, here is the loading solution, it works!

load.onClick = function () {
    //Remove old list items
    myList.removeAll()
    var filePathMinusExtension = app.activeDocument.fullName.fsName.substr(0, app.activeDocument.fullName.fsName.lastIndexOf("."));
    var ReadFile = File(filePathMinusExtension + "_GREP_Queries.txt");
    if (ReadFile.exists) {
        try {
            ReadFile.open("r");
            //
            var i = 0;
            while (ln = ReadFile.readln()) {
                var arr = ln.split(',');
                with (myList.add ("item", arr[i]+"\n")){
                    subItems[0].text = arr[1+i]+"\n";
                }                 
            }
            //Close the file
            ReadFile.close();
            alert("Done, the GREP Queries Loaded");
            return true;
        }
        catch (errOpen) {
            alert("Error. The GREP Queries file could not be opened!");
            return false;
        }
    }
    else{
        alert("The GREP Queries file could not be found!");
        return false;
    }
}
