如何使用值數組作爲參數進行原型ajax請求？

Question

我試圖做一個ajax更新原型與一些multirecordselect值發送請求。

Parameters: {"action"=>"use_campaign", "campaigns"=> ["27929","27932"] , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} 

，你可以看到該請求發送「運動」元素值的數組，我試圖做同樣的這個js代碼在原型7.

// get the campaigns 
var campaign_ids = {}; 
var campaigns = $('filter_form').getInputs("hidden","report[campaigns][]"); 
campaigns.each(function(field) { 
      campaign_ids.push(field.value); 
}); 

new Ajax.Updater('ad_filter', '/admin/reporting/use_campaign', { 
       method : 'get', 
       asynchronous : true, 
       evalScripts : true, 
       parameters : { 
        'advertiser_id' : $('filter_form')['report[advertiser_id]'].value, 
        'ad_id' : $('filter_form')['report[ad_id]'].value, 
        'campaigns' : campaign_ids 
       } 
}); 

的campaigns_ids在得到正確的信息像數組：

[ "27929", "27932" ] 

但目前看來，原型阿賈克斯更新發送請求等：

http://my_domain/admin/reporting/use_campaign?ad_id=&advertiser_id=&campaigns=27929&campaigns=27932 

什麼發出參數，如：

Parameters: {"action"=>"use_campaign", "campaigns"=> "27929" , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} 

我也tryed與

Object.toJSON(campaign_ids) 

但我只得到一個轉義字符串像

Parameters: {"action"=>"use_campaign", "campaigns"=>"[\"27929\",\"27932\"]" , "advertiser_id"=>"", "controller"=>"admin/reporting", "ad_id"=>""} 

有無論如何要做到這一點作爲我希望？

謝謝大家。

它看起來像你使用PHP作爲後端框架。 爲了確保PHP懂得陣列狀的GET參數，你need to add一個[]參數名：

  parameters : { 
       //... 
       'campaigns[]' : campaign_ids 
      }
