Window.Open Function Not Work In Google Chrome

I am really tired with Chrome, one of my window.open() Stuff work fine in FF and Opera in Fedora O.S. But Chrome Did not, my code is like:

Code:
<script type="text/javascript">
function getpage(id, type){
$.ajax({
type: "POST",
data: "key="+id,
async: false,
url: "<?php echo site_url(); ?>/server/precp/"+type,
success: function (msg) {
window.open("<?php echo site_url(); ?>/server/cplogin/"+msg, "autologin");
}});}
</script>

And it call in another JavaScript function like:
Code:
function doKeyup(id,e){
if(e == 13) {
var cp = $("table#serverdata tbody tr#container_tr.row_no td:nth-child(7) a#cp").html();
var dc = $("table#serverdata tbody tr#container_tr.row_no td:nth-child(7) a#dc").html();
if(cp != null || dc != null ) {
var firstId = $("table#serverdata tbody tr#container_tr.row_no td:nth-child(1) input[type=checkbox]").val();
}if(cp != null) {
alert("Enter here");
getpage(firstId,'cp');
return false;
}

And it firstly call from onkeyup as :
Code:
<input type="text" name="find_text0" id="find_text0" autocomplete="off" <?php if ('B' == $sb_pos) { ?> onfocus="document.getElementById('find_text1').value='';" <?php } ?> onkeyup = "return doKeyup('0',event.keyCode);" />
