The error message “control.setparent is not a function” is indicating that the setparent function is not defined or accessible on the control object. This means that you are trying to call the setparent function on a variable that does not have that function defined.
To understand this error further, let’s look at an example:
// Define a Control class
class Control {
constructor() {
// Some properties
}
}
// Instantiate an object of Control class
const control = new Control();
// Call the setparent function on control object
control.setparent(); // Error: control.setparent is not a function
In the above example, we have a Control class with a constructor and some properties. However, we have not defined a setparent function for the Control class. Therefore, when we try to call control.setparent(), we get an error stating that setparent is not a function.
To resolve this error, you need to ensure that the setparent function is defined for the control object. Here’s an updated example:
// Define a Control class
class Control {
constructor() {
// Some properties
}
setparent() {
// Implementation of setparent function
}
}
// Instantiate an object of Control class
const control = new Control();
// Call the setparent function on control object
control.setparent(); // No error
In the updated example, we have added the setparent function to the Control class. Now, when we call control.setparent(), it will execute without any error.
Make sure to check if the setparent function is defined for the control object or if there are any typos in accessing it. Sometimes, this error can also occur if the control object is not an instance of the expected class or if there is a conflict with other libraries.
Double-checking the code and verifying that the control object has the setparent function defined will help in resolving the “control.setparent is not a function” error.
