我在Javascript / jQuery中操作数据时遇到问题,我可以使用一些帮助。
我有一系列像这样的对象:
var projects = [
{title:'project1'},
{title:'project2'},
{title:'project3'},
];
我有另一个对象数组,如下所示:
ganttEvents = [
{
text: 'some text',
start_date: '2018/06/13',
end_date: '2018/06/14',
id: '1',
readonly: true,
project: 'project1',
category: 'scoping',
}
{
text: 'some text2',
start_date: '2018/06/14',
end_date: '2018/06/15',
id: '1',
readonly: true,
project: 'project2',
category: 'scoping',
}
{
text: 'some text3',
start_date: '2018/06/15',
end_date: '2018/06/16',
id: '1',
readonly: true,
project: 'project2',
category: 'design',
}
{
text: 'some text4',
start_date: '2018/06/13',
end_date: '2018/06/14',
id: '1',
readonly: true,
project: 'project2',
category: 'scoping',
}
{
text: 'some text5',
start_date: '2018/06/14',
end_date: '2018/06/15',
id: '1',
readonly: true,
project: 'project3',
category: 'testing',
}
{
text: 'some text6',
start_date: '2018/06/15',
end_date: '2018/06/16',
id: '1',
readonly: true,
project: 'project3',
category: 'build',
}
];
第二个对象中的项目字段将始终是第一个数组中的对象之一。
然后我需要得到一个如下所示的对象:
source: [
{
name: "project1", // a project defined in the projects array
desc: "scoping", // the category from the ganttEvents array of objects
values: [
{
to: "2018/06/13", // the start_date from the ganttEvents array of objects
from: "2018/06/14", // the end_date from the ganttEvents array of objects
desc: "some text", // the text from the ganttEvents array of objects
label: "some text", // the text from the ganttEvents array of objects
}
]
},
{
name: "project2", // a project defined in the projects array
desc: "scoping", // the category from the ganttEvents array of objects
values: [
{
to: "2018/06/14",
from: "2018/06/15",
desc: "some text2",
label: "some text2",
},
{
to: "2018/06/13",
from: "2018/06/14",
desc: "some text4",
label: "some text4",
},
]
},
{
name: "project3", // a project defined in the projects array
desc: "testing", // the category from the ganttEvents array of objects
values: [
{
to: "2018/06/14",
from: "2018/06/15",
desc: "some text5",
label: "some text5",
}
]
},
{
name: "project3", // a project defined in the projects array
desc: "build", // the category from the ganttEvents array of objects
values: [
{
to: "2018/06/15",
from: "2018/06/16",
desc: "some text6",
label: "some text6",
}
]
},
]
每个项目的所有阶段都可能有多个值,并且可能根本没有需要从源对象中省略事件的项目。
请你帮忙吗?
修改
这背后的背景是我使用SharePointPlus从SharePoint列表中提取事件列表。这会产生ganttEvents数组。我需要将其插入到jQuery.Gantt库中,该库需要以特定方式格式化事件。
我很抱歉,但我相对较新的Javascript(通常是Python程序员)我尝试过不同的方法,但无济于事。
答案 0 :(得分:1)
您可以使用-DEIGEN_INTERNAL_DEBUGGING
将数组分组到一个对象中。使用项目和类别的连接值作为键。使用reduce
将对象转换为数组。
Object.values

如果没有var ganttEvents = [{"text":"some text","start_date":"2018/06/13","end_date":"2018/06/14","id":"1","readonly":true,"project":"project1","category":"scoping"},{"text":"some text2","start_date":"2018/06/14","end_date":"2018/06/15","id":"1","readonly":true,"project":"project2","category":"scoping"},{"text":"some text3","start_date":"2018/06/15","end_date":"2018/06/16","id":"1","readonly":true,"project":"project2","category":"design"},{"text":"some text4","start_date":"2018/06/13","end_date":"2018/06/14","id":"1","readonly":true,"project":"project2","category":"scoping"},{"text":"some text5","start_date":"2018/06/14","end_date":"2018/06/15","id":"1","readonly":true,"project":"project3","category":"testing"},{"text":"some text6","start_date":"2018/06/15","end_date":"2018/06/16","id":"1","readonly":true,"project":"project3","category":"build"}];
var result = Object.values(ganttEvents.reduce((c, v) => {
let k = v.project + "-" + v.category;
c[k] = c[k] || {name: v.project,desc: v.category,values: []};
c[k].values.push({to: v.end_date,from: v.start_date,desc: v.text,label: v.text});
return c;
}, {}));
console.log(result);
,您可以使用Object.values()
