How to get a single object in an array to a JSON model

Question

I have a JSON model /details with 4 objects. I want the object based on the key :month.

   Object
   oData
   details:
   Array[4]
   0:Object
   1:Object
   2:Object
   3:Object
    editable:false
    key:"date"
    removeable:false
    value:"Day: TRUE, Night:False"
   4:Object
    editable:false
    key:"month"
    removeable:false
    value:"August"

The following is the code

/view

 var viewModel = that.getView().getModel();
 var viewModelData = viewModel.getData();

Working with objects is pretty easy. Check this link: developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/… — hcerim

You cannot query the object directly. You have to loop and search like so:

var viewModel = that.getView().getModel();
var viewModelData = viewModel.getProperty("/details");
var month = getObjectByKey(viewModelData, "month");

function getObjectByKey(a, key){
  for(var i = 0; i < a.length; i++){
  if (a[i].key === key){
    return a[i];
  }
  return null;
}

I get the model with the property, but I am not able to bind it.sap.m.Table({ columns: [ new sap.m.Column({ header: new sap.m.Text({ text: 'key',. }) }),], items: { path: '/details', template: new sap.m.ColumnListItem({ cells: [ What should be the path for binding to table

What do you want to achieve? Do you want to have a table with each detail object as row displaying their key and their value? Or do you want to display an array contained in the key="month" object in the table?
