I just want to know how to call a javascript function inside another function. If I have the code below, how do I call the second function inside the first?
function function_one()
{
alert("The function called 'function_one' has been called.")
//Here I would like to call function_two.
}
function function_two()
{
alert("The function called 'function_two' has been called.")
}
function function_one() {
function_two(); // considering the next alert, I figured you wanted to call function_two first
alert("The function called 'function_one' has been called.");
}
function function_two() {
alert("The function called 'function_two' has been called.");
}
function_one();A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).
function_one is a callable function. Such as in case of following mutation example. developer.mozilla.org/en-US/docs/Web/API/MutationObserver How can one call the function_two from within the callable function.
function function_one() {
function_two();
}
function function_two() {
//enter code here
}
function function_one()
{
alert("The function called 'function_one' has been called.")
//Here u would like to call function_two.
function_two();
}
function function_two()
{
alert("The function called 'function_two' has been called.")
}
function function_first() {
function_last();
alert("The function called 'function_first' has been called.");
}
function function_last() {
alert("The function called 'function_last' has been called.");
}
function_first();
