How can I get form data with JavaScript/jQuery?
Use $('form').serializeArray(), which returns an array:
[
{"name":"foo","value":"1"},
{"name":"bar","value":"xxx"},
{"name":"this","value":"hi"}
]
Other option is $('form').serialize(), which returns a string:
"foo=1&bar=xxx&this=hi"
Take a look at this jsfiddle demo
$('form').serialize() //this produces: "foo=1&bar=xxx&this=hi"

Updated answer for 2014: HTML5 FormData does this
var formData = new FormData(document.querySelector('form'))
You can then post formData exactly as it is - it contains all names and values used in the form.
