How to save highlighting to a database
- by vman
Hi
I am trying to highlight a part of the text on my website. This highlighted text will be saved for the specific user in a database and when the document is opened again it will show the previously highlighted text. I assumed I would be using javascript to highlight the text but I cannot seem to find a way to pinpoint where the word is that I am highlighting.
function getSelText()
{
var txt = '';
if (window.getSelection)
{
txt = window.getSelection();
}
else if (document.getSelection)
{
txt = document.getSelection();
}
else if (document.selection)
{
txt = document.selection.createRange().text;
}
else return "";
return txt;
}
I am using that to get the selection but I cannot figure out where the selection is in the text. The biggest annoyance is when I have duplicates within the line or text so if I were to use search then I would find the first instance and not the one I was looking for.
So the question is : How do you pinpoint a word or a selection in the entire document?
