<script>
window.BlobBuilder = window.BlobBuilder || window.WebKitBlobBuilder;

Blob.prototype.slice = Blob.prototype.slice || function(start, length) {
return this.webkitSlice(start, start + length);
}

</script>

Thanks in advanced!

@007JulienNov 11.2011 — Try this script

<script type="text/javascript">

a=3.14116;

alert("(true || a ) => "+(true || a));

alert("(null || a ) => "+(null || a));

alert("(false || a ) => "+(false || a));

alert('("carottes" || "navets") => '+("carottes" || "navets"));

alert('("" || "navets") => '+("" || "navets"));

</script>
