form表单内容转javascript对象

form表单内容转javascript对象，便于ajax提交数据


function serializeFormObject(selector) {
var a, o, h, i, e;
a = $(selector).serializeArray();
o = {};
h = o.hasOwnProperty;
for (i = 0; i < a.length; i++) {
e = a[i];
if (!h.call(o, e.name)) {
o[e.name] = e.value;
}
};
return o;
}


var formData = serializeFormObject('#saveForm');
