var sampleData = [], results = d.results;
for (var i = 0, len = results.length; i < len; i++) {
var result = results[i];
sampleData.push({ name: result.Name, Age: result.Age, Sex: result.Sex });
}

You just have to iterate through the results array in your javascript object and build a new array that has the data in the format you want.
您只需要遍历 javascript 对象中的结果数组并构建一个新数组，其中包含您想要的格式的数据。
var results = data.d.results;
var sampleData = [], item;
for (var i = 0, len = results.length; i < len; i++) {
item = results[i];
sampleData.push({name: item.Name, Age: item.Age, Sex: item.Sex});
}
