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
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.
