Hi,

https://idempiere.atlassian.net/browse/IDEMPIERE-5218 allows to copy some contents in clipboard.

Now, I would like to add an item to the right click > popup menu of a Description field to copy the content to the clipboard.
I've duplicated the code and it's working well when there is no line break.

String textToCopy = gridTab.get_ValueAsString("Description");
Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(\"").append(textToCopy).append("\");").toString());

But it throws this error when the content of the field has line breaks:

13:51:50.454===========> DefaultScriptErrorListener.onEvent: Clients.evalJavascript error! message: SyntaxError: "" string literal contains an unescaped line break, stack: b@https://localhost:8443/webui/zkau/web/b8d3d1b8/js/zk.wpd:9:838

v/</<@https://localhost:8443/webui/zkau/web/b8d3d1b8/js/zk.wpd:29:1924

and the content is not copied.

Any idea how to handle that?

Thanks,

Nicolas

Found some tip in stackoverflow

Try replacing the double quote with backtick, something like

Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(`).append(textToCopy).append(`);").toString());

I don't know if it works, just following the tip

Regards,

Carlos Ruiz

Thanks, I found several other similar solutions, but I can't find a way to implement them properly.
From what I understand, that must be done directly in the javascript, but I can't find the correct syntax :(

It still throws the error :

14:50:19.706===========> DefaultScriptErrorListener.onEvent: Clients.evalJavascript error! message: SyntaxError: "" string literal contains an unescaped line break, stack: b@https://localhost:8443/webui/zkau/web/b8d3d1b8/js/zk.wpd:9:838

Code is

else if (evt.getContextEvent().equals(COPY)) {

String textToCopy = gridTab.get_ValueAsString("Description");

textToCopy = textToCopy.replace("\\n", "\\\\n");

Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(\"").append(textToCopy).append("\");").toString());

}


:-/

Perhaps your string has "\r" too, try
textToCopy = textToCopy.replace("\\n", "\\\\n");
textToCopy = textToCopy.replace("\\r", "\\\\r");

Still not :(

Here's the field on iDempiere (field with a 2 lines content):

2024-06-06 16_16_17-Expert Light local — Mozilla Firefox.png

click on Copy trigger this code

String textToCopy = gridTab.get_ValueAsString("Description");

System.out.println("Original:\n" + textToCopy);

textToCopy = textToCopy.replace("\\n", "\\\\n");

textToCopy = textToCopy.replace("\\r", "\\\\r");

System.out.println("Final:\n" + textToCopy);

Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(\"").append(textToCopy).append("\");").toString());


And log:

Original:

Comunicazione creata per i documenti iniziali

bla bla bla

Final:

Comunicazione creata per i documenti iniziali

bla bla bla

Am I missing something?

My mistake, should be the following instead:

textToCopy = textToCopy.replace("\n", "\\\\n");
textToCopy = textToCopy.replace("\r", "\\\\r");

Almost there :)

There is error message anymore, but the 'output' is :

Comunicazione creata per i documenti iniziali\nbla bla bla

Logs:

Original:

Comunicazione creata per i documenti iniziali

bla bla bla

Final:

Comunicazione creata per i documenti iniziali\\nbla bla bla

Well, probably just a case of reducing the "\":

textToCopy = textToCopy.replace("\n", "\\n");
textToCopy = textToCopy.replace("\r", "\\r");

Yes !!!!!

Is working now, thanks a lot !!

Final code is

String textToCopy = gridTab.get_ValueAsString("Description");

textToCopy = textToCopy.replace("\n", "\\n");

textToCopy = textToCopy.replace("\r", "\\r");

Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(\"").append(textToCopy).append("\");").toString());

:-)  My fault, as said, just writing untested code, forgot to close the quotes, it must be something like this:

Clients.evalJavaScript(new StringBuffer("navigator.clipboard.writeText(`").append(textToCopy).append("`);").toString());

The text block approach suggested by Carlos should be the cleaner and better approach.
