我需要获取 JSON 数据中每一列的总计。下面是我的 JSON 数据，我想获取每列的总计。
[
{"campaign":"MD001","seen":650,"taken":62,"eligible":542,"total":1000,"ind":"E"},
{"campaign":"MD002","seen":550,"taken":52,"eligible":342,"total":1000,"ind":"E"},
{"campaign":"MD003","seen":800,"taken":69,"eligible":642,"total":1000,"ind":"W"},
{"campaign":"MD004","seen":500,"taken":62,"eligible":527,"total":1000,"ind":"E"},
{"campaign":"MD005","seen":350,"taken":29,"eligible":992,"total":1000,"ind":"w"},
{"campaign":"MD006","seen":550,"taken":52,"eligible":342,"total":1000,"ind":"W"}
]
上面的意思是“合格”，每个“合格”都有不同的值，所以我需要从上面的数据中获得“合格”的总数。
最佳答案
那么你必须计算一下:
var data = // your json data
var total = 0;
for(var i = 0; i < data.length; i++){
total += parseInt(data[i].eligible);
}
