Question

I have an array containing objects. I fill a dropdown using the array. How can the elements in the dropdown be arranged based a property of the object say ID?

The array has 3 elements (read objects at indexes 0,1, and 2). I want to rearrange my dropdown based on a property of the object in the array, say ID (which is 3,1 and 2 respectively).

Currently even if I bind the dropdown with sorted array, it is a futile effort, as the dropdown is indexed based on the name of the property.

_data.push(objItem[i]); 
// here the array is being populated with data after it has been populated, I'm filling a dropdown using
 System.Utils.fillSelectData("$selectDDL", _data, "FieldValue", "FieldText");
//our framework supports this code But every time the binding is being done based on FieldText..

Any insight would be highly obliged..

Answer 1

ordering objects by id example:

    var employees=[]
        employees[0]={id: 1, name:"George", age:32}
        employees[1]={id: 4, name:"Edward", age:17}
        employees[2]={id: 2, name:"Christine", age:58}
        employees[3]={id: 3, name:"Sarah", age:62}

    var sorted = employees.sort(function(a, b) {
       return a.id-b.id 
    });

    for(var i=0;i<sorted.length;i++) {
       alert(sorted[i].id); 
    }
