While inputting text into a frame, I am looking to execute a script.
I want this script to target the specific text frame where my cursor is located.
How can I reference this particular textFrame using Javascript?
While inputting text into a frame, I am looking to execute a script.
I want this script to target the specific text frame where my cursor is located.
How can I reference this particular textFrame using Javascript?
Let's consider the code snippet below:
var selectedItem = app.activeDocument.selection[0];
if (selectedItem instanceof InsertionPoint &&
selectedItem.parentTextFrames[0] instanceof TextFrame) {
var textFrame = selectedItem.parentTextFrames[0];
// This code shows that the variable `textFrame` holds a reference to the text frame - now let's delete it!
textFrame.remove();
} else {
alert("The cursor is not placed in a text frame");
}
Explanation:
We start by getting a reference to the selected item in the document using this line of code:
var selectedItem = app.activeDocument.selection[0];
We then check if the selection qualifies as a "cursor in a Text Frame" by:
InsertionPoint.parentTextFrames belongs to a TextFrame.if (selectedItem instanceof InsertionPoint &&
selectedItem.parentTextFrames[0] instanceof TextFrame) {
// ... If we reach here, then the "cursor is in a Text Frame".
}
If the checks confirm that the "cursor is in a Text Frame" are true, we assign the reference of the Text Frame to a variable named textFrame. For example:
var textFrame = selectedItem.parentTextFrames[0];
To demonstrate that the variable textFrame indeed refers to the text frame, we delete it!
textFrame.remove(); // Perform actions on the text frame !
If the checks indicating whether the "cursor is in a Text Frame" are false, we inform the user that "The cursor is not placed in a text frame".
Selected text characters in a Text Frame
In case the user has chosen text characters in a text frame instead of just placing the cursor in one, you can adjust the conditional check in the code above like this:
if ((selectedItem instanceof InsertionPoint || selectedItem instanceof Text)
&& selectedItem.parentTextFrames[0] instanceof TextFrame) {
// ...
