在提交之前使用 javascript/jQuery 从表单中提取 post 参数

Question

how can i get the parameters of any form being submitted with method=post before it's submitted using javascript(preferably jQuery). What i am trying to do is get the post parameters and submit it to an alternate loacation. i was using

$('form').submit(function() {
  alert('action=  ' + $(this).attr("action"));
  alert('serialized string' + $(this).serialize());
  return false;
});

but it works only with get request i want to extract the parameters from the post requests too .

Answer 1

Something like this works for me

$('#form').submit(function(){
        $.post(your_location, $(this).serialize());
    return false;
  });

You can use the any other Ajax method you like if you don't want to use $.post(). You can also include a callback method to handle whatever your ajax call returns.
