getSelection & surroundContents across multiple tags
- by lethalbody
Hi,
I've got a script that changes the background colour of text that has been selected. However i'm encountering an issue when the text is selected across multiple elements/tags.
The code that i've got is:
var text = window.getSelection().getRangeAt(0);
var colour = document.createElement("hlight");
colour.style.backgroundColor = "Yellow";
text.surroundContents(colour);
And the error being output is:
Error: The boundary-points of a range does not meet specific requirements. =
NS_ERROR_DOM_RANGE_BAD_BOUNDARYPOINTS_ERR
Line: 7
I believe this is to do with the getRange() function though i'm not too sure how to proceed since I am a beginner at javascript.
Is there any other way I can replicate what I am trying to achieve?
Many thanks.
