Text selection in chrome etc

Question

function getPosition () { if ($.browser.msie) { var textPosition = document.selection.createRange().duplicate(); } else($.browser.mozilla || $.browser.opera || $.browser.safari) { var textPosition = window.getSelection(); } } <div><textarea rows="3" cols="50" name="textarea1" id="textarea1" onChange="javascript:storeCursorPosition();" onClick="javascript:getPosition();" onKeyPress="javascript:getPosition();" onFocus="javascript:getPosition();"></textarea></div> <input type="Button" onclick="javascript:if(textPosition.text == null){alert('No position selected')}else{alert('position selected')};">

I have the above code, which is not working in Chrome, Safari etc. I'm getting the "No position selected" alert all the time, except for IE. In IE I get the "position" alert..

Any idea why it's not working except for IE??

There is no need to browser sniff! if (window.getSelection) { } else {} — epascarello

textPosition has no scope outside of the getPosition() function. Adding it as a variable of window should work, but isn't ideal:

var textPosition = null; function getPosition () { if(!window.getSelection) { textPosition = document.selection.createRange().duplicate(); } else { textPosition = window.getSelection(); } }

Aaahhh :) but still no working :( I'v created a jsfiddle here: jsfiddle.net/5qtLS and even if I write something in the textarea, in chrome it still alert me with no position selected. When you click in the textarea and click the button it should remain position to textarea and alert with position selected.
