cómo agregar una cadena en una matriz dinámica

Aquí solo tengo una identificación, ¿cómo puedo modificar para obtener (37398351478977: 1, 42110385783015: 1) cadena para poder agregar esto en ajax para agregar al carrito?

 var values=[]; $(".ex_product_select").change(function(){ if($(this).is(":checked")) values.push($(this).val()); else{ var x = values.indexOf($(this).val()); values.splice(x,1) ; } $(".hide_extra_variant").text(values); }); $(document).on("click",".add",function(){ jQuery.post('/cart/update.js', { updates: { values } }); });
 <script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script> Product1 : <input type="checkbox" class="ex_product_select" style="display:inline-block;" name="exselect" value="37398331392193"> Product2 : <input type="checkbox" class="ex_product_select" style="display:inline-block;" name="exselect" value="37398351478977"> Product3 : <input type="checkbox" class="ex_product_select" style="display:inline-block;" name="exselect" value="42110385783015"> <button class="add" value="add_to_cart">Add To Cart</button> <p class="hide_extra_variant"></p>

 var values=[]; $(".ex_product_select").change(function(){ if($(this).is(":checked")) values.push({key:values.length+1,value:$(this).val()}); else{ var x = values.findIndex(x => x.value == $(this).val()); values.splice(x,1) ; } console.clear(); console.log(values) let allValues = "(" + values.map(x => x.value + ":1").join() + ")"; $(".hide_extra_variant").text(allValues); }); $(document).on("click",".add",function(){ jQuery.post('/cart/update.js', { updates: { values } }); });
