javascript - 如何从json中获取仅数字键值对

Question

我有这样的 Json 数据

{
   "info":[
      {
         "Name":"Noob Here",
         "Major":"Language",
         "Sex":"Male",
         "English":"15",
         "Japanese":"5",
         "Calculus":"0",
         "Geometry":"20"
      },
      {
         "Name":"Noob Here",
         "Major":"Calculus",
         "Sex":"Female",
         "English":"0.5",
         "Japanese":"40",
         "Calculus":"20",
         "Geometry":"05"
      }
   ]
}

我只需要获取值为数值数据的键值对。

预期输出

{
"English":"15",
"Japanese":"5",
"Calculus":"0",
 "Geometry":"20"
},
{
 "English":"0.5",
"Japanese":"40",
"Calculus":"20",
"Geometry":"05"
}

是否有任何插件，或者我应该使用正则表达式为其编写长的 jquery 代码？

Answer 1

使用 jquery isNumeric 来查找是否为数字..然后使用对象和数组..您需要两个循环来获取对象...

给你..

var finalObj={};  //this is final output object
var info = [];  //array to push to finalObj
$.each(data.info,function(i,v){
  var object={};
  $.each(v,function(i1,val1){
    if($.isNumeric(val1)){

        object[i1]=val1
    }
  });
  info.push(object);
});
finalObj['info']=info;
console.log(finalObj);
