解决方法
这是我在我的select2字段上所做的
<%= f.input :field_name,as: :select,collection: f.object.field_name,include_blank: false,selected: f.object.field_name,input_html: { class: "json_data" },%>
json_data是如何使文本字段进入选择2
咖啡
$('.json_datas').before ()->
"<input name='#{@.name}' type='hidden' />"
$('.json_data').select2
allowClear: true,placeholder: "Select a value",ajax:
url: '/api/call_to_data'
dataType: 'json'
delay: 250
data: (params) ->
{
q: params.term
page: params.page
}
processResults: (data,page) ->
# parse the results into the format expected by Select2.
# since we are using custom formatting functions we do not need to
# alter the remote JSON data
{ results: data.items }
cache: true
我希望这可以帮助你
