Text deselected on right click in IE8

问题

I want the user selection from a text area in my page. I have a context menu that user can use on right-clicking the selection. This is my code to retrieve selected content from a textarea in IE8,

var textComponent = document.getElementById('myTextArea');
var selectedText;
// IE version
if (document.selection != undefined)
{
textComponent.focus();
selectedText= document.selection.createRange();
alert(sel.text);
}

Now I notice that before allowing the blocked content(i.e the javascript) I can select a text in the text area and on right click it does not get deselected. But, when I allow the script, on right clicking the text that i selected gets deselected. Which is why i cannot retrieve the content.

I searched the web but didn't get any solution. Can anyone pls tell me what the problem is?

Thanks a lot.

Calling the focus() method of the texbox or using the focus() method of any element on the page will clear the text selection.

Keep text selection when focus changes
