Value is not passed on javascript code in django -

-

i new django , javascript both. , using highcharts displaying charts. problem @ template file.

visualise.html contains

<script type="text/javascript">     var yname_agewise_total_call_duration = {{ yname.agewise_total_call_duration|safe }};     var yname_agewise_weekly_total_call_duration = {{ yname.agewise_weekly_total_call_duration|safe }}; </script>

i tested value of yname.agewise_total_call_duration , yname.agewise_weekly_total_call_duration in html file shows well. when want use value yname_agewise_total_call_duration , yname_agewise_weekly_total_call_duration

in javascript file charts.js cannot show values. tried in charts.js as

alert(yname_agewise_total_call_duration);

the popup displays undefined.

what problem here ? how solve ?

in javascript, undefined means variable has been declared has not yet been assigned value. check on browser console whether yname_agewise_total_call_duration holds data or not
