Is there any way I can call the validate() function outside the initValidation() function in JavaScript?
We wish to call the function validate() outside of initValidation(), without necessarily having to call initValidation()
Following is our problem code −
function initValidation(){
// irrelevant code here
function validate(_block){
// code here
}
}In JavaScript, as we know that functions are nothing but objects, so to achieve this we can tweak our code like this −
function initValidation(){
// irrelevant code here
function validate(_block){
// code here
console.log(_block);
}
this.validate = validate;
}What this tweak does is that it makes our parent function to represent a class now, of which validate is a property and we can access it like this −
const v = new initValidation();
v.validate('Hello world');Following is the complete code with output −
Example
function initValidation(){
// irrelevant code here
function validate(_block){
// code here
console.log(_block);
}
this.validate = validate;
}
const v = new initValidation();
v.validate('Hello world');Output
The output in the console will be −
Hello world
