When selecting HTML content, there can be situations where only a part of the desired text is highlighted. In such cases, it becomes necessary to expand the selection to encompass the entire element containing the selected text.
some te<b>xt here is bold</b>ed, I guess
|______________________| <- the selection range
For example, if the selected text is "ere is bolded, I gue", but you actually want to include the whole BOLD tag, you can achieve this by checking if the anchor and focus nodes have different parent elements.
To expand the selection, you can use rangy's setStartBefore(Node) method as described in the documentation: http://code.google.com/p/rangy/wiki/RangyRange
Here is how you can modify the range:
a = rangy.getSelection()
b = a.getRangeAt(0)
b.setStartBefore(a.anchorNode.parentNode)
If you encounter any issues with the undefined response, you may need to troubleshoot further or seek assistance from experts like Tim Down who provided solutions for similar problems.
UPDATE: Tim Down's suggestion prompts us to reconsider the scenario where the selection should have expanded to include Mass Ef.
