It is common knowledge that we can retrieve the selection of text in JavaScript using the following method:
var range = window.getSelection ();
However, how can we obtain the style of this selection? For example, when I select bolded text or italicized text, how can I determine their styles?
(One idea I have is to get the position of the selected text and retrieve the HTML at that specific position...)
Utilize the document.queryCommandState() method for checking if text is in bold or italic, and use document.queryCommandValue() to determine font size and style.
Remember to provide a flag to each method in order to receive a true or false value, as it will not automatically return the current styles. For example, to check if selected text is bold, you can write...
if(document.queryCommandState('Bold')){
// it's bold!
}
This information provides a range of identifiers and methods.
If you're looking to determine the status of formatting commands like "Bold" and "Italic" that don't have a value, you can utilize document.queryCommandState() (check out dottoro). For commands that do have a value, such as "FontName," consider using document.queryCommandValue() (also see dottoro).
