when I use these code in the sharepoint designer then not enable quick launch bar on web part page
Paste this within the <head> tag. This will enable jquery:
<!– Include jquery library –>
<script src=”http://code.jquery.com/jquery-latest.js”></script>
Paste this within the <form> tag. This will ensure that the left navigation is always visible:
<scripttype="text/javascript"> $(document).ready(function(){ $("#s4-leftpanel").show(); $(".s4-ca").css('margin-left','155px');});</script>
but it show space for the quick launch bar but not display quick launch bar.
