Solve JavaScript error split is not a function

The JavaScript String ‘split is not a function’ error occurs when are calling the string function on an object that is not a string. This can happen when you are trying to use a string method on an array, for example. The solution is to convert the object to a string first using the toString() method or similar.

how to solve javascript split is not a function error

The String split() method takes a string, and splits it into an array of substrings. However, the method will only work if you are passing in a string value. If it is passed in any other type of object as an argument, an error will occur.

Here is an example of an error when you call the split() method on a date object. To fix this, you can use the toString() method to convert the object into a string first.

var date = new Date();

date.split(” “); // TypeError: date.split is not a function

var date = new Date();

date.toString().split(” “); // works!

Another way to fix the issue to check that the type of the object is string before calling the split() method.

var date = new Date();

if (typeof date == “string”) {

date.split(” “); // works!

} else {

console.log(“date is not a string”);

}

typeof is a JavaScript function that can be used to check the type of an object. If you pass in a string value, it will return “string”.

In the code above, we use if/else statements to check whether date is a string before calling the split() method. If it is a string, we call the split() method and pass in ” “, which will break apart the date value into an array of substrings. If it does not contain a string value, then we print an error message to let us know that something went wrong.

So, if you ever encounter the JavaScript error “split is not a function”, remember to check the type of the object before calling string methods. You can use the toString() method or other conversion functions, or else you can use the typeof() function to check for string values before calling methods such as split().
