Question

我从文件中获取json数据并在每个循环中创建另一个json文件，并在此处发送对json文件的请求是我创建json文件的代码

var  derivatedFeatures = ["RMS","sb2xMagnitudev_ipspeak", "sbSubsynchronousv_ipspeak", "PeakPeak_mil", "sbHighFrequency_grms", "TruePeak_ips", "PeakPeak_g", "sb1xMagnitudev_ipspeak","Crestfactor"];

$.each(derivatedFeatures,function(index,feature){

  $.each(data,function(index,item){

    var featurefile ="Lines_"+feature+'_'+item['Line']+'_'+item['Component'].split(" ").join("_")+'.json'

    filedata = {
      file:featurefile,
      site:item['Site'],
      area:item['Area'],
      line:item['Line'],
      equipment:item['Equipment'],
      component:item['Component'],
      feature:feature
    };

    frank.sendAjax('/static/data/json/'+featurefile,'', 'GET', anomaliesDataAppend,filedata);
  });
});

我想首先加载10个文件
页面滚动后我想再加载10个
并继续处理

执行此操作的原因
页面在加载所有json文件并处理其数据时卡住
我有2000多个json文件

我希望这有助于你：这是我为您的解决方案编码

$.each(derivatedFeatures,function(index,feature){

                            $.each(data,function(index,item){
                                indexnum++;
                         var featurefile ="Lines_"+feature+'_'+item['Line']+'_'+item['Component'].split(" ").join("_")+'.json'
                         filedata.push({file:featurefile,
                            site:item['Site'],
                            area:item['Area'],
                            line:item['Line'],
                            equipment:item['Equipment'],
                            component:item['Component'],
                            feature:feature,
                            indexnum:indexnum
                        });
                            });


                    });
                    loadFeatureFiles(filedata,0);




   var loadFeatureFiles = function(filedata,indexnum){
    var startfrom=indexnum;
    var endto=startfrom+10;
    for (var i=startfrom;i <= endto;i++) {
        requestdata={filedata:filedata[i],indexnum:i};
          frank.sendAjax('/static/data/json/'+filedata[i]['file'],'', 'GET', anomaliesDataAppend,requestdata);
    };
};

分配data = rows，当用户向下滚动并传入函数

时获取

//data is induxnum
      loadFeatureFiles(filedata,data);

我需要在10个文件间隔内解析json文件
