if item type: 'boolean', issue

[jupe]

if checkbox is unchecked and press submit button, uncheck state is not regonized at all because of serializeArray() . There is one fix for jquery ( https://github.com/madrobby/zepto/pull/248/commits ), but i think it is not added to main jQuery branch. One possible way to fix this issue is to add concat just after serializeArray() -->

line: 2138
/* Because serializeArray() ignores unset checkboxes and radio buttons: */
formArray = formArray.concat(
$(':input[type=checkbox]:not(:checked)', this.el).map( function() {
return {"name": this.name, "value": this.checked}
}).get()
);

Isn't this how this is handled in pure html forms as well?

I included the provided patch in 8d3bb01.

I initially did that because I thought that validation would fail if the schema key was defined as required in the schema and the user left the box unchecked. Having checked with a real example, I realized that required has another meaning in Web browsers: a required checkbox must be checked for validation to succeed in a Web browser that supports the required attribute. Since that's not the meaning of the required property in JSON Schema, I disabled the addition of a required attribute to checkbox fields in 4a00a47.

That second change means that there is no way to define a checkbox that users must check before they proceed (a typical example would the infamous "by clicking here, you agree with our terms of service"). I do not know how to express such a flag in JSON Schema though.
