You can use length to see if your selector matched 1 anything.

if ($('#MyId').length) {
    // do your stuff
}

Assuming you are trying to find if a div 1 exists

$('div').length ? alert('div found') : alert('Div not found')

You can use the visible selector:

jQuery should be able to find even hidden 3 elements. It also has the :visible and :hidden selectors 2 to find both visible and hidden elements.

Does 1 this help? Not sure without more info.

if ($("#MyId").length) { ... write some code here ...}

This from will automatically check for the 2 presence of the element and will return 1 true if an element exists.

I use this:

if ($('.div1').size() || $('.div2').size()) {
    console.log('ok');
}
