Question

我试图让json中的项目有条不紊地排列。我能够选择json中存在的“term”值，但是可以按照我在预期输出部分中显示的方式进行排列吗？我添加了一个jsfiddle链接来显示我到达的位置：

[{
        "_index": "test",
        "id": "YMFT112",
        "_source": {

                    "Map": [

YMFT113; Company;   Microsoft Corp; Microsoft;  http://testLink.com/2;

Answer 1

您可以在本机可用时使用JSON对象，或使用JSON2作为垫片。

之后，只需使用JavaScript的内置排序功能即可。您提供了一个与数组项相互比较的函数

var myArray = JSON.parse(jsonString);
myArray.sort(function(a, b){
    var nameA = a._source.Map.Company.term;
    var nameB = b._source.Map.Company.term;

    if (nameA === nameB) {
        return 0;
    } else if (nameA < nameB) {
        return -1
    }
    return 1;
});

Answer 2

使用eval('(' + json_object + ')')，您将能够创建JavaScript对象。此对象将是一个数组，您可以使用.访问属性。例如，如果您的json_object被称为数据，例如：然后

    var temp = eval('(' + data + ')'); // temp now is an array.

如果您想要访问_index对象中的第一个id或json：

    "_index": "test",
    "id": "YMFT112",

发出警报（temp[0]._index），它会显示"test"。对于其他属性，请遵循相同的逻辑。 This stackoverflow问题或JSON页面将帮助您了解在其他任务中您必须完成的任务才能完成任务。雅虎有一个名为YUI的API，可能会更有帮助。

将javascript对象转换为有序的逗号分隔值
