Check whether the user name is a valid email address

<bag id=pPage act=verify><we name="lets.go" type="mail">@{pPage:username}</we></bag>

Determine whether the verification is successful (if the verification fails, set v_pass of the pPage schoolbag to false and record the prompt information with pop. out)

<If x = "@ {pPage: lets. go} "> <bag id = pPage x = false> <we name =" v_pass "> false </we> <we name =" pop. out "> @ {pPage: pop. out} \ n Email: it must be a real email address! </We> </bag> </if>

Check whether the password is empty(If it is empty, set v_pass of the pPage schoolbag to false and record the prompt information with pop. out)

<If x = "@ {trim: @ {pPage: pass }}"> <bag id = pPage> <we name = "v_pass"> false </we> <we name = "pop. out "> @ {pPage: pop. out} \ n password: cannot be blank! </We> </bag> </if>

Check whether all verification items have passed

<If x = "@ {pPage: v_pass}" else = 1> <we x = false> <script> alert ("Verification Failed! \ N @ {pPage: pop. out} "); location. href = '@ {head: referer}'; </script> </we> <! -- Check the username and password -->... </we> </if>

If it fails, a prompt is output and the previous page is returned. If it succeeds, the logon operation is performed.
