Theserialize() method creates a standard URL-encoded text string by serializing form values. Its operation object is a jQuery object representing a collection of form elements.

3. Only "successful controls" will be serialized into strings. If you do not use a button to submit the form, the submit button's value is not serialized. If you want a form element's value to be included in a sequence string, the element must use a name attribute.
4. The name in the form cannot use keywords in Js and jquery.
For example: length
//Use:$("#form1").serialize();
The value above cannot be obtained.
