Put comments in the scripts

Fred Yes, that is a very good question. I'm trying to update the Ninox code to accept both indifferently, JavaScript and/or comments. I will come soon with a solution for all (I hope ).

Sean Sorry, the prompt function does not exist in the Mac app. But M. Daaboul  told me that it was possible to insert HTML in the text of the Dialog function. I think that with this it is possible to remake the prompt function by adding an input field and retrieve the value.
 

Sean I found a solution about prompt for Mac app and Web. I use the solution of M. Daaboul  with the dialog function and NativeJS :

var ret := dialog("Title of dialog box", ---
<div class='component editor  editor-string' style="display : block;">
<label for='fname'>Whats your name is ?</label>
<input type='text' class='nx-input nx-input__value' id='fname' name='fname' value='your name' onchange='window._dialogValue = this.value;'></div>
---, ["cancel", "ok"]);
if ret = "ok" then
    var r := #{:text return window._dialogValue}#;
    alert("result is : " + r)
end

The onchange event of the input element (end of line 4) puts the entered value in the global JavaScript variable _dialogValue.
Then, if the result of the dialog is "ok", put the value of _dialogValue in the variable r Ninox (line 7).

Note: I put several element nesting to get the same visual result as a Ninox field. But you can just put an input element (line 4) and it works just as well. 

A more structured, reusable solution might look like this: 

function promptText(titleBox : text,caption : text,defaultValue : text) do
    var ret := dialog(titleBox, ---
<div class='component editor  editor-string' style="display : block;"><label for='fname'>{ caption }</label><input type='text' class='nx-input nx-input__value' id='fname' name='fname' value='{ defaultValue }' onchange='window._dialogValue = this.value;'></div>
---, ["cancel", "ok"]);
    {
        validate: ret = "ok",
        value: #{:text return window._dialogValue}#
    }
end;
var r := promptText("Title of dialog box", "Whats your name is ?", "your name");
if r.validate then
    alert("result : " + r.value)
end

Sean Thank's for your help. 

Maybe it is because NativeJS is not initialized on Ninext ? See here to do so.

I have attached an example database. Let me know if it work on your mac (or web) app.

Sean Sean That's strange, I copied the same code to my console and everything works fine (app and wab). Have you tried the Test prompt.ninox that I attached just before?

Sean Surprising . wich version of Ninox do you have ?

Sean The best is to look directly in the application:

Sean That's good! 
I tried to compare the 3.5 version (I don't have the 3.6) and the current 3.7 and I don't see anything that can explain this problem!?
If anyone has an older version, I want them to try it and tell me if it works or not.

Jacques TUR It is also possible not to use NativeJS for the prompt. It is necessary to use a temporary field (for example a field in global memory):

var t := this;
var r := {
        titleBox: "Title of dialog box",
        caption: "Whats your name is ?",
        defaultValue: "your name",
        returnField: "_Value"
    };
var body := ---
<div class='component editor  editor-string' style="display : block;"><label for='fname'>{ r.caption }</label><input type='text' class='nx-input nx-input__value' id='fname' name='fname' value='{ r.defaultValue }'
onchange='
var field = database.schema.typeOf("{ string(t.Id) }").findElement("{ r.returnField }");
database.update("{ string(t.Id) }", field.id, this.value, null );
'></div>
---;
var ret := dialog(text(r.titleBox), body, ["cancel", "ok"]);
if ret = "ok" then
    'Résult of prompt' := _Value
end

We then use the JavaScript of the function onchange to call the code of Ninox and thus update the field _Value (line 11 and 12).

It is less flexible, but there is no need for an add-on.

See the example in attachment.
