问题描述
我有一个Json数据,需要排序才能显示。我的Json如下我需要根据ColumnLocation对它们进行排序。
I have a Json data that I need to sort before display it. My Json is as below. I need to sort them based on the ColumnLocation.
[{
"Name": "PieChart",
"Id": "1",
"ColumnLocation": "0",
"RowLocation": "0"
}, {
"Name": "Calendar",
"Id": "2",
"ColumnLocation": "1",
"RowLocation": "0"
}, {
"Name": "FavouriteFilter",
"Id": "3",
"ColumnLocation": "2",
"RowLocation": "0"
}, {
"Name": "FilterResults",
"Id": "4",
"ColumnLocation": "0",
"RowLocation": "1"
}, {
"Name": "Watched",
"Id": "5",
"ColumnLocation": "1",
"RowLocation": "1"
}]
即排序的数组应该有以下方式的项目
i.e the sorted array should have items in following fashion
col : 0, row 0
col : 0, row 1
col : 1, row 0
col : 1, row 1
推荐答案
不需要lodash /下划线。您可以使用 Array.prototype.sort :
由于你的值是字符串,你必须首先将它们解析成数字,然后比较:
No need for lodash/underscore. You can use Array.prototype.sort: Since your values are strings, you must first parse them into numbers and then compare:
let a = [{"Name":"PieChart","Id":"1","ColumnLocation":"0","RowLocation":"0"},{"Name":"Calendar","Id":"2","ColumnLocation":"1","RowLocation":"0"},{"Name":"FavouriteFilter","Id":"3","ColumnLocation":"2","RowLocation":"0"},{"Name":"FilterResults","Id":"4","ColumnLocation":"0","RowLocation":"1"},{"Name":"Watched","Id":"5","ColumnLocation":"1","RowLocation":"1"}]
let sorted = a.sort((a, b) => parseInt(a.ColumnLocation) - parseInt(b.ColumnLocation));
console.log(sorted);
