var DictionaryItems= response.value;
if (DictionaryItems == null || typeof(DictionaryItems) != “object”)
{
return;
}
var myDropDownList = document.getElementById(“myDropDownList”);
myDropDownList.options.length = 0;
for (var i = 0; i < response.value.length; ++i)
{
myDropDownList.options[myDropDownList.options.length] = new Option(response.value[i].Value,response.value[i].Key);
}
}
