Are you familiar with how to include an operator in an object (rather than the entire class)? When it comes to a method, I know you can achieve that by:
my_object.new_function = function(){return 1};
Then invoking my_object.new_function() will output 1.
However, what I'd like to do is apply the get operator to access my_object.new_function directly instead of using my_object.new_function().
There are a multitude of methods -
let obj = {
get propX() {
return 1
}
}
console.log(obj.propX)
// 1
obj = {
...obj,
get propY() {
return 2
}
}
console.log(obj.propX, obj.propY)
// 1 2
Object.assign(obj, { get propZ() { return 3 } })
console.log(obj.propX, obj.propY, obj.propZ)
// 1 2 3Getters function like regular functions and thus capture their surroundings -
let obj = {
get propA() { return 1 }
}
let variableB = 2
obj = {
...obj,
get propC() { return variableB } // <- dynamic
}
console.log(obj.propA, obj.propC)
// 1 2
variableB = 999
console.log(obj.propA, obj.propC)
// 1 999I am looking to transfer data from a form to another PHP page without using a button within the form itself. Instead, I have placed a separate button outside of the form for submission. How can I achieve this by sending the form data to the other page? Bel ...
