I have an array like below:
var sphValues = [1, 2, 3, 4, 5];
then I need to convert above array like as below one:
var sphValues = ['1', '2', '3', '4', '5'];
How can I convert? I used this for auto-complete.

You can use map and pass the String constructor as a function, which will turn each number into a string:
sphValues.map(String) //=> ['1','2','3','4','5']
This will not mutate sphValues. It will return a new array.

For older browsers which do not support Array.map, you can use underscore.js: _.map(sphValues, String)
Devin B.
Unfortunately, this will also convert booleans to strings.
just by using array methods
var sphValues = [1,2,3,4,5]; // [1,2,3,4,5]
sphValues.join().split(',') // ["1", "2", "3", "4", "5"]

Use Array.map:
var arr = [1,2,3,4,5];
var strArr = arr.map(function(e){return e.toString()});
console.log(strArr); //["1", "2", "3", "4", "5"]
Edit:
Better to use arr.map(String); as @elclanrs mentioned in the comments.
for(var i = 0; i < sphValues.length; i += 1){
sphValues[i] = '' + sphValues[i];
}

Use .map() at this context that is a better move, as well as you can do like the below code this would add more readability to your code,
sphValues.map(convertAsString);
function convertAsString(val) {
return val.toString();
}

ES6 solution
const nums = [1, 2, 3, 4, 5, 10];
// bugfix: the `10` edge case
const strs = Array.from(nums, x => `${x}`);
console.log(strs);
// ['1', '2', '3', '4', '5', '10']git diff
- const strs = Array.from(nums.join(``));
+ const strs = Array.from(nums, x => `${x}`);

you can just append a '' to convert it to a string type.
var sphValues = [1,2,3,4,5];
for(var itr = 0; itr<sphValues.length;itr++){
sphValues[itr] = '' + sphValues[itr];
}

var value;
for (var i = 0; i < data3.sph.length; i++) {
value = data3.sph[i];
//sphValues[i] = data3.sph[i];
var obj = {
label: value
};
sphValues.push(obj);
}
You can use this method for auto complete. I think your problem will be solved, but it will not convert like you want, it will convert like
["label": "val1", "label": "val2"]

Another solution using map:
let nums = [1,2,2,4,3,2,5,6]
let all_to_str = nums.map(num => {return num.toString()})
console.log(all_to_str)
Output:
[ '1', '2', '2', '4', '3', '2', '5', '6' ]

just by using the array.map method, you can convert an array of numbers into an array of string
var sphValues = [1, 2, 3, 4, 5];
const numberToStringArray = sphValues.map((number) => {
return number.toString();
});
console.log(numberToStringArray); //['1', '2', '3', '4', '5']
sphValues.map(String)[1,2,3,4,5].toString().split(",")
