I want to convert this json object that contain string value separated by comma to array:
[
{id: 1,
name: 'book',
colors: 'red, yellow, blue'
},
id: 2,
name: 'book',
colors: 'red, yellow, blue'
}
]
to:
[
{id: 1,
name: 'book',
colors: ['red', 'yellow', 'blue']
},
id: 2,
name: 'book',
colors: ['red', 'yellow', 'blue']
}
]
in javascript, thank you!
You can do the following,
data = [
{'id': 1,
'name': 'book',
'colors': 'red, yellow, blue'
},
{'id': 2,
'name': 'book',
'colors': 'red, yellow, blue'
}
];
ret = data.map((item) => {
return {...item, colors: item.colors.split(',').map(item => item.trim())};
})
console.log(ret);
', ' then you can remove the map and trimStrings get into arrays in each object.
let arr = [
{id: 1,
name: 'book',
colors: 'red, yellow, blue'
},
{id: 2,
name: 'book',
colors: 'red, yellow, blue'
}
]
for (let index in arr) {
let colorsIntoArr = arr[index].colors.split(',');
arr[index].colors = colorsIntoArr;
}
/*
[
{
"id": 1,
"name": "book",
"colors": [
"red",
" yellow",
" blue"
]
},
{
"id": 2,
"name": "book",
"colors": [
"red",
" yellow",
" blue"
]
}
]
*/
console.log(arr)
