[easyUI]select如何动态添加option

Train of thought:

1.Write a API for getting values from json, format like: "abc","123","345"

2.Put the widget init into ajax block

function appendSenderAddress(){
  var url = '../foo.do';  
  $.ajax({
    url : url,
    type : 'GET',
    success : function(data, status){
      if(data == 'Please login first'){
        return;
      }
      var statusCode = data.code;
      if (statusCode == '0') {
        var value = data.foo;
        console.log('value: ' + value)
        var valueList = value.split(",")
        $.each(valueList,function(i,item){
          console.log(i,item)
          $('#value_list').append("<option value='"+item+"'>"+item+"</option>")
        })
        initWidget()
      } else {
        initWidget()
      }
    }
  });

}      

function initWidget(){
  var valuetElem = new Choices('#value_list', {
        delimiter: ',',
        editItems: true,
        maxItemCount: 5,
        removeItemButton: true,
      });
}
