How to check if element has autoNumeric initialized

Question

How to check if an HTML element already has autoNumeric initialized, so i won't initialize it again?

Initializing it twice results in all input numbers appearing twice.

if (// autonumeric not yet initialized) {
    var anObject = new AutoNumeric(document.querySelector(inputSel), autoNumericSettings);
}

Edit: The reason to check is that autoNumeric might be previously initialized elsewhere, in another script with different autoNumericSettings and this script needs to respect the earlier set settings.

Answer 1

probably, you can use getAutoNumericElement(domElement) to check if an HTML element already has autoNumeric initialized

if (AutoNumeric.getAutoNumericElement(domElement) === null) {
    var anObject = new AutoNumeric(document.querySelector(inputSel), autoNumericSettings);
}

Answer 2

You can indeed use AutoNumeric.getAutoNumericElement(domElement) as Aliaksandr mentioned to check if an element is returned, but the official way to check if a DOM element is already managed by AutoNumeric is this:

AutoNumeric.isManagedByAutoNumeric(domElementOrSelector);

So your code should be updated like so:

let anObject;
if (!AutoNumeric.isManagedByAutoNumeric(inputSel)) {
    // Also, no need to querySelector `inputSel` here:
    anObject = new AutoNumeric(inputSel, autoNumericSettings);
}
