i have this array
let arr = [
{
"time": "3",
"wholeObj": "abc mo sa 3 Y",
"mapEventValue": "Y"
},
{
"time": "3",
"wholeObj": "abc a 3 G",
"mapEventValue": "G"
},
{
"time": "3",
"wholeObj": "cba d 3 S f",
"mapEventValue": "S"
},
{
"time": "3",
"wholeObj": "cba z 3 R",
"mapEventValue": "R"
}
]
i need to sort the array FIRST based on the time value and after that if the time values are equal i need to sort them based on mapEventValue
in following order G Y R S
So in my case all objects are having equal time values 3 I can't find a way to sort them by the mapEventValue property
what i tried
Until now i just managed to sort them by time value
let sorted = arr.sort((a,b) => a.time - b.time)
So my output at the end should be
let arr = [
{
"time": "3",
"wholeObj": "abc a 3 G",
"mapEventValue": "G"
},
{
"time": "3",
"wholeObj": "abc mo sa 3 Y",
"mapEventValue": "Y"
},
{
"time": "3",
"wholeObj": "cba z 3 R",
"mapEventValue": "R"
},
{
"time": "3",
"wholeObj": "cba d 3 S f",
"mapEventValue": "S"
},
]
So only sort by time if time differs, otherwise sort by the index of your desired sort order.
let sortOrder = 'GYRS';
let arr = [
{
"time": "3",
"wholeObj": "abc mo sa 3 Y",
"mapEventValue": "Y"
},
{
"time": "3",
"wholeObj": "abc a 3 G",
"mapEventValue": "G"
},
{
"time": "3",
"wholeObj": "cba d 3 S f",
"mapEventValue": "S"
},
{
"time": "3",
"wholeObj": "cba z 3 R",
"mapEventValue": "R"
}
];
let sorted = arr.sort((a,b) => {
if (a.time != b.time) {
return a.time - b.time;
} else {
return sortOrder.indexOf(a.mapEventValue) - sortOrder.indexOf(b.mapEventValue);
}
});
console.log(sorted);
