我正在尝试使用来自发送请求的多记录选择的一些值在原型中进行ajax更新.

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

正如你所看到的那样,请求将"campaigns"元素作为一个值数组发送,我试图用这个js代码在原型7上做同样的事情.

// 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
                }
 });

campaigns_ids正在获取正确的信息,如:

[ "27929", "27932" ]

但似乎原型ajax更新正在发送一个请求,如:

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

什么发送参数如:

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

我也尝试过

Object.toJSON(campaign_ids)

但我只得到一个逃脱的字符串

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