Now in my web app I deserialize JSON and bind to HTML5 dropdown to get following

What I am trying to get to is that; How can I modify JSON data so that when I bind to dropdown, Value is state code and text is full state name so some thing like this

  <option value="IL">Illinois</option>

Answer 1

Please note there is options and optionsText in the data-bind attribute for a <select> element.

If you json is:

States:[
    { name:'Illinois', value:'IL'},
    { name:..., value:...},
    ....
]


<select data-bind="
    options: value, // IL, ... 
    optionsText: name, // Illinois, ...
    value: lead().state, 
    optionsCaption: 'Choose state...'">
</select>

Answer 2

Only minor change I had to make from Blaise's reply was as below

  <select data-bind="
     options: states, 
     optionsValue: 'value'// IL, ... 
     optionsText: 'name', // Illinois, ...
     value: lead().state, 
     optionsCaption: 'Choose state...'">
  </select>
