Answer 1

As far as I am aware .click will attach to the item when it is executed, if the item is not there, in the case of a widget it will not be attached. I could be wrong on that, try this and see if it works.

$('body').on('click', '#myID', function() {
    ...
});

Try to use jQuery function, not $.

Your code would be this:

jQuery("#myID").click(function(){
    var name = jQuery("#name").val();
    var phone = jQuery("#phone").val();
    console.log(name +" "+ phone); 
    if(name.length > 1 && phone.length > 7){
        jQuery.ajax({
            url: 'my_url',
            type: 'post',
            data: {'name': name,
            'number': phone},
            success: function(data){
                jQuery(".header-bg-title").html('thanks');
                jQuery("span.white").hide();
            },
            error: function(response){
                alert('error'); 
            }
        });
    } else {
        jQuery("p#onerror").html('write your name & number');
    }
});

or you can wrap your code in an IIFE receiving jQuery in your $

(function($) {
// your code here
}(jQuery));

I guess you currently have a function like this

$(document)ready(function(){
  $("#myID").click(function(){
    var name = $("#name").val();
    var phone = $("#phone").val();
    console.log(name +" "+ phone); 
    if(name.length > 1 && phone.length > 7){
    $.ajax({
        url: 'my_url',
        type: 'post',
        data: {'name': name,
        'number': phone},
        success: function(data){
        $(".header-bg-title").html('thanks');
        $("span.white").hide();
        },
        error: function(response){
            alert('error'); 
        }
    });
    } else {
        $("p#onerror").html('write your name & number');
    }
  });
}

If so it should be as easy as changing the $(document)ready(function(){ to jQuery(document).ready(function($) and keeping the rest the same.

jQuery(document).ready(function($) 
{
 $("#myID").click(function(){
        var name = $("#name").val();
        var phone = $("#phone").val();
        console.log(name +" "+ phone); 
        if(name.length > 1 && phone.length > 7){
        $.ajax({
            url: 'my_url',
            type: 'post',
            data: {'name': name,
            'number': phone},
            success: function(data){
            $(".header-bg-title").html('thanks');
            $("span.white").hide();
            },
            error: function(response){
                alert('error'); 
            }
        });
        } else {
            $("p#onerror").html('write your name & number');
        }
      });
}

This solution allows you to keep using $('#idofitem')
