Incorrect number of elements submitted by Form JS

See the following table:

 

 

<Form ID = "loginform" Action = "login. php? Act = signin "method =" Post "> <br/> <p id =" message "> </P> <br/> <p> <br/> <label = "username"> User Name: </label> <br/> <input type = "text" class = "login_input" id = "username" name = "username" size = "20"/> <br/> </P> <br/> <p> <br/> <label for = "password"> password: </label> <br/> <input type = "password" class = "login_input" id = "password" name = "password" size = "20"/> <br/> </P> <br/> <p> <br/> <label for = "code"> Verification Code: </label> <br/> <I Nput type = "text" name = "code" id = "code" class = "code" size = "5"/> <br/> <span> <br/> "/> <br/> </span> <br/> </P> <br/> <p id =" remember "> <br /> <input type = "checkbox" name = "remember" value = "1" id = "R"/> <br/> <label for = "R"> Save my login information this time. </Label> <br/> </P> <br/> <Div class = "login_bar"> <br/> <input type = "Submit" id = "act" class = "sub"/> <br/> </div> <br/> </form> 

Below is the JavaScript code used to verify the submission form:

 $ ("# Loginform "). submit (function () {<br/> var userid = $ ("# username "). val (), <br/> pwd =$ ("# password "). val (), <br/> code = $ ("# Code "). val (), <br/> result = true, <br/> message = $ ("# message"); <br/> act = $ ("# Act "). removeattr ("disabled", ""); <br/> If (userid. length = 0 | PWD. length = 0 | code. length = 0) <br/>{< br/> result = false; <br/> message. stop (false, true) <br/>. HTML ("All items are required! ") <Br/>. slidedown ("normal") <br/>. CSS ("background", "Red"); <br/> F = function () {<br/> message. slideup ("normal"); <br/>}< br/> T = setTimeout ("F ();", 5000); <br/> $ (this ). find ("input "). click (function () {f (); window. cleartimeout (t) ;}); <br/>}< br/> If (result) {act. addclass ("subload "). ATTR ("disabled", "disabled") ;}< br/> return result; <br/> }); 

PS: there is no problem with the company's computer. When I got home, I felt strange how I could not find the act in the post. No problem was found on the internet, and no problem was found on the form. It was confirmed repeatedly that the elements to be submitted in the form were added with name. By accident, I changed the above result method to direct return false/true; no problem.

PS2: The company is still not good, good guy, there is a way to only take signin behind the action.

This is strange. Why? Is it related to the environment? Remember this for the moment and update it later.
