javascript - 更改数组对象的元素

Question

首先here is a fiddle 。我想动态更改变量data的参数。如果您查看 Firebug 控制台，您可以查看数据数组对象。我查了很多资料，但找不到数据。

简而言之，我想使用 return_data 元素重新生成数据数组对象。 return_data 对象的元素是动态的。在 fiddle它有 3 个元素，但可能与 3 个不同。我如何动态地更改它？

提前致谢。

var return_data = [{"name":"mrzurafa","count":315,"pop":5,"impact":7.37},{"name":"mutcato","count":20,"pop":5,"impact":56},{"name":"s0lukciyerli","count":3488,"pop":5,"impact":25.65}];

var data = google.visualization.arrayToDataTable([
  ['name','impact','pop','temp','count'],
  ['beyinsiz',80.66,1.67,2,33739900],
  ['mutcato',79.84,1.36,4,81902307],
  ['s0lukciyerli',78.6,1.84,8,5523095],
  ['herbkubilenadam',81.55,2.96,10,748560000],
  ['mrzurafa',88.09,2.05,40,307007000]
]);

Answer 1

您可以尝试一下，这会返回一个新列表，其结构与您的 return_data 完全相同:

var return_data = [{"name":"mrzurafa","count":315,"pop":5,"impact":7.37},{"name":"mutcato","count":20,"pop":5,"impact":56},{"name":"s0lukciyerli","count":3488,"pop":5,"impact":25.65}];

var data = ([
  ['name','impact','pop','temp','count'],
  ['beyinsiz',80.66,1.67,2,33739900],
  ['mutcato',79.84,1.36,4,81902307],
  ['s0lukciyerli',78.6,1.84,8,5523095],
  ['herbkubilenadam',81.55,2.96,10,748560000],
  ['mrzurafa',88.09,2.05,40,307007000]
]);

//prepare object
var item = {}
for (j=0;j<data[0].length;j++) {
    item[data[0][j]] = "";
}

//prepare list of objecs
var objs = []

for (i=1;i< data.length;i++) {
    item['name'] = data[i][0];
    item['impact']=data[i][1];
    item['pop']=data[i][2];
    item['temp']=data[i][3];
    item['count']=data[i][4];
    objs.push(item)
}

console.log(objs)

希望它能有所帮助。
