Add list in JSON! Javascript parsing!

Background JavaCode!

 
OBJ = questionservice. showsubjectinfo (subjectid, subjecttype); Teacher = (teacher) actioncontext. getcontext (). getsession (). get ("teacherinfo"); int departid = teacher. getdepartment (). getdepartid (); List <object []> courselist = courseservice. findallcoursebydepart (1, 10, departid); object [] O = new object [] {courselist}; obj. add (o); Return "success ";
 

JavaScript code:

VaR DATA = xmlreq. responsetext; var list = eval ("(" + Data + ")"); var DIV = document. getelementbyid ("dialog"); var result = "select a course: <SELECT>"; var courses = List. OBJ [1]; var courselist = courses [0]; for (var k = 0; k <courselist. length; k ++) {var courseval = courselist [k]; result + = "<option value = '" + courseval [0] + "'>" + courseval [1] + "</option> ";} result + = "</SELECT> <br/>"; for (VAR I = 0; I <list.
