jquery - Converting a text input to a select element with JavaScript

Question

I'm doing some front end development on a hosted e-commerce platform. The system sends a text input for the customer to choose the quantity of items they want to add to their cart, but I would prefer a select. I don't have access to the markup the system spits out in this regard, so I'd like to use JavaScript to change the text input to a select element.

I used jQuery to remove the select and duplicate the input element with a select with the right choices, but when I try to add something to my cart, only one item is added, regardless of the choice in the select.

Here's the native markup:

<div id="buy-buttons">
  <label>Quantity:</label>
  <input name="txtQuantity" type="text" value="1" id="txtQuantity" class="ProductDetailsQuantityTextBox">
  <input type="submit" name="btnAddToCart" value="Add To Cart" id="btnAddToCart" class="ProductDetailsAddToCartButton ThemeButton AddToCartThemeButton ProductDetailsAddToCartThemeButton">
</div>

Here's the jQuery I'm running to update my markup.

 $("#txtQuantity").remove();
 $("#buy-buttons").append('<select id="txtQuantity" type="text" value="1" class="ProductDetailsQuantityTextBox"></select>');
 $("#txtQuantity").append('<option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option>');

Does anyone know why this isn't working? Shouldn't the select be submitting the information to through the form in the same way as the text input?

Thanks!

Use replaceWith instead of remove and append. Also the type attribute on the <select> is unnecessary and the <option> nodes should be within the <select>. Here's the docs on replaceWith - http://api.jquery.com/replaceWith/.

$("#txtQuantity")
    .replaceWith('<select id="txtQuantity" name="txtQuantity" class="ProductDetailsQuantityTextBox">' +
          '<option value="1">1</option>' +
          '<option value="2">2</option>' +
          '<option value="3">3</option>' +
          '<option value="4">4</option>' +
          '<option value="5">5</option>' +
        '</select>');
