Question

I am trying to bind this submit event from a form which not always be in Dom, so I trying with .on():

$('body').on("form","submit", function(e){})

but firebug logs:

$(“body”).on is not a function
[Parar en este error]

$(‘body’).on(“form”,”submit”, function(e){

tried also

$(document).on("form","submit", function(e){})

If you are upgrading to jQuery 1.7, you can use on() by applying form as a selector, like:

$('body').on("submit", "form", function(e){

Which will bind the submit event to body, but filtering it to form which works the same way as the delegate example below.

If you are using 1.4.2 or newer, you can use delegate() like this:

$('body').delegate("form", "submit", function(e){
