selected text and xy coordinates
how to get a selected text and xy coordinates of the开发者_Python百科 word in the same time??
Just googled it:
var txt = "";
if (window.getSelection) {
txt = window.getSelection();
} else if (document.getSelection) {
// FireFox
txt = document.getSelection();
} else if (document.selection) {
// IE 6/7
txt = document.selection.createRange().text;
}
txt = txt.toString()
There is no simple way to get X/Y coordinates of the selected text. Because it dependes on its container position and size, text font, text layout, and many many other variables.
To expand on @MatuDuke's answer, you can get the position of the selected text like so:
var txt = window.getSelection(),
range = txt.getRangeAt(0),
boundary = range.getBoundingClientRect();
// Available positions:
// boundary.top
// boundary.bottom
// boundary.left
// boundary.right
These will give you pixel values relative to the viewport. However, it doesn't seem to work within text areas, a problem I'm currently trying to solve.
I am using this jQuery plugin http://plugins.jquery.com/node/7411 for a project and it seems to be working flawlessly. You could use jQuery to get the position of mouse http://docs.jquery.com/Tutorials:Mouse_Position
Here is some sample code I have worked on
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html lang="en">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript" src="jquery.textselect.js"></script>
<script type="text/javascript">
$(function(){
$('#select').bind('textselect click', function(e){
console.log(e.text);
console.log(e.pageX);
})
});
</script>

You could try something like this
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript" src="jquery.textselect.js"></script>
<script type="text/javascript">
$(function(){
$('#select').bind('textselect click', function(e){
console.log(e.text);
console.log(e.pageX);
var selected_text = e.text
var original_text = $(this).text();
var parts = original_text.replace(e.text, "/").split("/");
for(i in parts) {
console.log(parts[i])
}
})
});
</script>
