Improving JSON Structure in a New Post

When attempting to send the id and quantity as integers, I encountered an issue where the id was being posted as a string instead. Despite defining them as integers in my code, this problem persisted.

I know I must be missing something simple here, but I just can't seem to figure it out. How can I ensure that both id and quantity are sent as integers? The code snippet causing the problem is outlined below:

  var id = parseInt(identifier, 20);
  var quantity = parseInt(amount, 10);
  var updates = {};
  updates[id] = quantity;
  $.post('/cart/update.js', {updates: {updates}});

The expected JSON format for the post data should resemble this:

$.post('/cart/update.js', {updates: {40076307207: 1}});

Your insights on resolving this issue would be greatly appreciated. Thank you!

Answer №1

When using $.post, JSON is not sent; instead, it uses the

application/x-www-form-urlencoded
format. This format treats all data as strings without distinguishing data types. If a parameter needs to be an integer, it must be converted in the server code.

Additionally, in JSON, object keys are always treated as strings.

To achieve the desired structure, the syntax should be:

$.post('/cart/update.js', {updates: updates});

It seems like you have added an extra level of nesting by writing {updates}. The correct syntax would be {updates: updates}, resulting in sending {updates: {updates: updates}}.
