如果数量增加，则使用jQuery更改WooCommerce的“添加到购物车”按钮文本

Question

WooCommerce Add To Cart Button text change using jQuery if Quantity increase.

    jQuery(document).on("change",'.minus', function() { 
  var productquantity = jQuery('.qty').attr('value');
    if  (productquantity == 15) {
          jQuery('.single-product').each(function() {
        jQuery(".single_add_to_cart_button").text("REQUEST A QUOTE");
    });
      }
})

While selecting buttons value never changes :S

HTML FOR BUTTON AND SELECTOR

<div class="quantity buttons_added">
    <input type="button" value="-" class="minus button is-form"><input type="number" step="1" min="1" max="9999" name="quantity" value="1" title="Qty" class="input-text qty text" size="4" pattern="[0-9]*" inputmode="numeric"><input type="button" value="+" class="plus button is-form"></div>

<button type="submit" name="add-to-cart" value="1520" class="single_add_to_cart_button button alt" style="display: block !important">Add to Cart</button>

 $(document).ready(function () { $('body').on("click",'.minus',function () { var qtyval = $('.qty').val(); if(qtyval >= 0) { var newQTY = parseInt(qtyval) - parseInt(1); if(newQTY >= 15) { $('.single_add_to_cart_button').text("Request a Quote"); } if(newQTY < 15) { $('.single_add_to_cart_button').text("Add to Cart"); } $('.qty').val(newQTY); } }); $('body').on("click",'.plus',function () { var qtyval = $('.qty').val(); var newQTY = parseInt(qtyval) + parseInt(1); if(newQTY >= 15) { $('.single_add_to_cart_button').text("Request a Quote"); } $('.qty').val(newQTY); }); });

jQuery(document).on("click",'.plus, .minus', function() { 
  var productquantity = jQuery('.qty').attr('value');
    if  (productquantity == 15) {
          jQuery('.single-product').each(function() {
        jQuery(".single_add_to_cart_button").text("REQUEST A QUOTE");
    });
      }  else if(productquantity != 15) {
          jQuery('.single-product').each(function() {
        jQuery(".single_add_to_cart_button").text("ADD TO CART NOW");
    });
      }
})

Only problem was on change to onclick.
