[FIXED] Probleme mit Photoshops Onchanging -Funktion

Ausgabe

Ich versuche, einen Beschriftungstext abhängig vom Status eines Kontrollkästchens für die Benutzeroberfläche von Photoshop Script zu ändern. Nur aktualisiert es überhaupt nicht. Keine Ahnung warum.

Idealerweise möchte ich, dass es “Some text” sagt, wenn es angekreuzt ist, und “Some other text” , wenn es nicht markiert ist. Und sich dynamisch verändern.

Hier ist mein Code

// DIALOG
// ======
var dlg = new Window("dialog");
   dlg.text = "Title"; 
   dlg.preferredSize.width = 180; 
   dlg.preferredSize.height = 100; 
   dlg.orientation = "column"; 
   dlg.alignChildren = ["center","top"]; 
   dlg.spacing = 10; 
   dlg.margins = 16; 

var statictext1 = dlg.add("statictext", undefined, undefined, {name: "statictext1"}); 
   statictext1.text = "Some static text"; 
   statictext1.justify = "center"; 

var checkbox1 = dlg.add("checkbox", undefined, undefined, {name: "checkbox1"}); 
   checkbox1.text = "Some text";
   checkbox1.value = true;
   

// GROUP1
// ======
var group1 = dlg.add("group", undefined, {name: "group1"}); 
    group1.orientation = "row"; 
    group1.alignChildren = ["left","center"]; 
    group1.spacing = 10; 
    group1.margins = 0; 

// add buttons
group1.add ("button", undefined, "OK");
group1.add ("button", undefined, "Cancel");

// Define behavior for when the slider value changes
dlg.checkbox1.onChanging = function() 
{
   var textArr = ["Some text", "Some other text"]
   var val = dlg.checkbox1.value;
   // Update the label text with the current checkbox value.
   dlg.checkbox1.text = textArr[val];
}

var myReturn = dlg.show();

Lösung

Das CheckboxSteuerelement löst das onClickEreignis und nicht das onChangingEreignis aus.

Die einzigen Steuerelemente, die das onChangingEreignis auslösen, sind:

• EditText
• Scrollbar
• Slider

Erwägen Sie daher, diesen Teil in Ihrem Skript zu ändern:

// Define behavior for when the slider value changes
dlg.checkbox1.onChanging = function() {
  // ...
}

stattdessen zu Folgendem:

// Define behavior for when the checkbox value changes
dlg.checkbox1.onClick = function() {
   var textArr = ["Some text", "Some other text"]
   var val = checkbox1.value ? textArr[0] : textArr[1];
   statictext1.text = val;
}

Erläuterung

Im Körper der vorangehenden Funktion für das onClickEreignis, dh der Teil, der liest;

var val = checkbox1.value ? textArr[0] : textArr[1];

we utilize the conditional (ternary) operator to check the value property of checkbox1. If checkbox1 is checked (true) we assign the string "Some text" to the val variable, otherwise if checkbox1 is unchecked (false) we assign the string "Some other text" to the val variable instead.

Additional changes:

The following changes also need to be carried out:

1. As checkbox1‘s initial value is set to true, i.e. it’s checked, you’ll need to change line number 13 from this:

   statictext1.text = "Some static text";
   

   to this:

   statictext1.text = "Some text";
   

2. Also consider setting the size property for statictext1. As you can see on line number 15 below the following has been added:

   statictext1.size = [180, 20];
   

   This will ensure it’s width accomodates the "Some other text" string.

Revised script:

Hier ist das vollständig überarbeitete Skript:

// DIALOG
// ======
var dlg = new Window("dialog");
    dlg.text = "Title";
    dlg.preferredSize.width = 180;
    dlg.preferredSize.height = 100;
    dlg.orientation = "column";
    dlg.alignChildren = ["center","top"];
    dlg.spacing = 10;
    dlg.margins = 16;

var statictext1 = dlg.add("statictext", undefined, undefined, {name: "statictext1"});
    statictext1.text = "Some text"; // <--- Note: Also change this !
    statictext1.justify = "center";
    statictext1.size = [180, 20];   // <--- Note: Also set the width/height !

var checkbox1 = dlg.add("checkbox", undefined, undefined, {name: "checkbox1"});
    checkbox1.text = "Some text";
    checkbox1.value = true;


// GROUP1
// ======
var group1 = dlg.add("group", undefined, {name: "group1"});
    group1.orientation = "row";
    group1.alignChildren = ["left","center"];
    group1.spacing = 10;
    group1.margins = 0;

// add buttons
group1.add ("button", undefined, "OK");
group1.add ("button", undefined, "Cancel");

// Define behavior for when the checkbox value changes
dlg.checkbox1.onClick = function() {
   var textArr = ["Some text", "Some other text"]
   var val = checkbox1.value ? textArr[0] : textArr[1];
   statictext1.text = val;
}

var myReturn = dlg.show();
