javascript - 我需要以 10 个文件为间隔解析 json 文件

Question

我从文件中获取 json 数据，并在每个循环中创建另一个 json 文件并发送对该 json 文件的请求，这是我用于创建 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);
  });
});

• 我想先加载 10 个文件
• 页面滚动后我想再加载 10 个

• 并且进程继续

  这样做的原因

• 加载所有 json 文件并处理其数据时页面卡住
• 我有 2000 多个 json 文件

我希望这对您有帮助: 这是我为您的解决方案编写的代码

$.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 并在用户向下滚动并传入函数时获取

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