Get table id by click in td using jQuery

In the click handler you can use .closest()

$(this).closest('table').attr('id')

$("#tableID").on("click","input[type='text']",function(){

$(this).closest('table').attr('id');

});

reference closest()

You should delegate event to avoid multiple handlers, and then use delegateTarget to target current TABLE:

$('table').on('click', 'input', function (e) {
    alert(e.delegateTarget.id);
});
