Suppose I have Qusetion paper.Which displays some question with there options.I have got qustion with proper selected option.But I am not succeed to store it in proper models instance.I know how to store single record to particular model instance.But I dont know how to store repetative values to a particular model object.How I solve this probelm.

1) here is my some contrller file code

temp:function()
    {
        var obj = Ext.create('Demo.model.Poll');
        for(var i=0;i<4;i++)
        {
                var inputs = document.getElementsByName(i); 
                var radio = "";  
                for (var j = 0; j < inputs.length; j++) {
                    if (inputs[j].checked) {
                        name = inputs[j].name;
                        value  = inputs[j].value;
                        //console.log("questionId="+name +" value="+ value);
                        check.set('poll',name);
                        check.set('option',value);
                    }// End of if statment
                }// End of inner for loop
          }//End of outer for loop

        //Here I am going to display values inside object  
        console.log("----------------------------------");
          for(var i=0;i<4;i++)
          {
              console.log(i);
              console.log(check.get('poll'));
              console.log(check.get('option'));
          }
    //Is it possible to save object array to server side in single save method
    //  obj.save();

}// End of temp function

Answer 1

I have found the solution to my question and here is the answer.

//code for getting question name and value from view and send to server side in a asingle request
check:function()
{
    //creating objects in javascript
        var storeObject=this.getStore('qb.QbquestionoptionStore');
    for(var i=0;i<=4;i++)
    {
            var inputs = document.getElementsByName(i); 
            var radio = "";  
            for (var j = 0; j < inputs.length; j++) {
                if (inputs[j].checked) {
                    name = inputs[j].name;
                    value  = inputs[j].value;
                    console.log("questionId="+name +" value="+ value);
                        var check = Ext.create('Balaee.model.qb.QbquestionoptionModel');
                        check.set('questionId',name);
                        check.set('option',value);

                    storeObject.add(check);
                  //console.log("User Infooooooooo: option="+check.get('option')+"questionId="+check.get('questionId'));
                }// End of if statment
            }// End of inner for loop
      }//End of outer for loop
    // code to display data in store object 
      for(var i=0;i<4;i++)
      {
          var record=storeObject.getAt(i);
          console.log("record no="+i);
          console.log("Qusetion Id="+record.get('questionId'));
          console.log("Option="+record.get('option'));
          console.log();
      }
      storeObject.sync();
}// End of check function
