c# - call function from Controller in javascript code -


using d3.js graphs, added graph in view cshtml page. want values in graph withdraw db. wrote following function in controller:

    protected int getreadinessavg()     {         var avgreadiness = 0;         var countitems = 0;         foreach (var item in db.reviews)         {             avgreadiness = avgreadiness + item.lecturerreadine;             countitems++;         }         avgreadiness = avgreadiness / countitems;          return avgreadiness;     }

this function works great , return relevant value. now, in graph (the js code), want use value. here trying do..

 var freqdata = [                  { state: '2013', freq: { lecturerreadine: '<%=getreadinessavg()%>', lecturertransferrate: 412, lecturerattitude: 674, lecturerknowledge: 2001 } }                 , { state: '2014', freq: { lecturerreadine: 932, lecturertransferrate: 2149, lecturerattitude: 418, lecturerknowledge: 4726 } }                 , { state: '2015', freq: { lecturerreadine: 832, lecturertransferrate: 1152, lecturerattitude: 1862, lecturerknowledge: 2135 } }                 ];

but call function: lecturerreadine: '<%=getreadinessavg()%>' isn't working. suggestions?

as @remy grandin said, can't directly call controller method javascript. can call c# function in .cshtml page. use @functions {..}

@functions{   protected int getreadinessavg()     {         var avgreadiness = 0;         var countitems = 0;         foreach (var item in db.reviews)         {             avgreadiness = avgreadiness + item.lecturerreadine;             countitems++;         }         avgreadiness = avgreadiness / countitems;          return avgreadiness;     }  }

then assign value.

var freqdata = [                  { state: '2013', freq: { lecturerreadine: '@getreadinessavg()', lecturertransferrate: 412, lecturerattitude: 674, lecturerknowledge: 2001 } }                 , { state: '2014', freq: { lecturerreadine: 932, lecturertransferrate: 2149, lecturerattitude: 418, lecturerknowledge: 4726 } }                 , { state: '2015', freq: { lecturerreadine: 832, lecturertransferrate: 1152, lecturerattitude: 1862, lecturerknowledge: 2135 } }                 ];
