jquery - how to bind data to dropdown dynamically using knockout.js? -


i new knockout.js. wasn't able bind data api dropdown using knock out js.

my json data api , dropdown is:

[{ contactid: 0, firstname: "aaa", lastname: "bbb", mobilenumber: null, startdate: "0001-01-01t00:00:00", enddate: "0001-01-01t00:00:00" }, { contactid: 0, firstname: "ccc", lastname: "ddd", mobilenumber: null, startdate: "0001-01-01t00:00:00", enddate: "0001-01-01t00:00:00" } ] <select id="selectmenu1" name="" data-theme="c" data-bind="optionscaption: 'choose...'">        </select>

i bind firstname,lastname,contactid dropdown , display firstname , lastname text , contactid value field item. please give suggestions regarding this?

you need use options binding, need specify:

  • your array of items in options (see in doc example 3)
  • you need set optionsvalue: 'contactid' have contactid value
  • you need specify function in optionstext builds select texts (see in doc example 4)

so final binding like:

<select id="selectmenu1" name="" data-theme="c"    data-bind="options: contacts,               optionsvalue: 'contactid',               optionstext: function(i) { return i.firstname + ' ' + i.lastname },               optionscaption: 'choose...'">         </select>

demo jsfiddle.
