I'm working with a code snippet that looks like this:
for(var j=0; j < this.arr.length; j++) {
arr.push({
id: 'j',
label: this.arr[j],
display: () => this.arr[j]
})
}
I am curious about how to set the value inside single quotes (' ') for each iteration. I would like it to be something like '1', '2', '3' .....
To make things easier, you can simply utilize the .toString() method.
for(let i = 0; i < this.array.length; i++) {
array.push({
id: i.toString(),
label: this.array[i],
display: () => this.array[i]
})
}
let array = [];
for(let i = 0; i < [1, 2, 3, 4].length; i++) {
array.push({
id: i.toString()
})
}
console.log(array)To include quoted numbers, follow these steps:
var arr = ["foo", "bar", "baz"];
var res = [];
for (let i = 0; i < arr.length; i++) {
res.push({
id: `'${i}'`,
label: arr[i],
display: () => arr[i]
})
}
console.log(res);This method uses template literals to insert i within the string with single quotes.
Please note that using var for i in your display function may result in an unexpected value for arr[i]. To resolve this issue, consider using let instead of var.
The following code snippet assigns the values '0', '1', '2' ... to id.
for(var i=0; i < this.arr.length; i++) {
arr.push({
id: '\''+i.toString()+'\'',
label: this.arr[i],
display: () => this.arr[i]
})
}
The main issue lies in the necessity to convert your variable i of type number to a type of string
Instead of writing:
id: 'i',
You should use:
id: i.toString(),
or
id: ''+i,
or
id: `${i}`,
Modify the id by changing from 'i' to " ' "+i+" ' ",
