javascript - How to create additional fields and remove them from a form? -


i trying allow users add additional email fields if want add additional email accounts, , hit remove if hit not want add field. however, cannot remove button work, , also, trying somehow differentiate each class including variable emailcount in each class not working either reason...

here jquery script: (it in document ready function)

  var = 0;  $(function(){                =+ 1;         var emailcount = "email" + i.tostring();         console.log(i);         console.log(emailcount);         $('.addemail').click(function() {               $('#addinfo').append('<div class="' + emailcount '"></div><form class="newemail", method="post", action="newemailpost"> <label>' + emailcount + '</label>' + '<input name="' + emailcount + '", type="email", value=""/><br><input type="submit", class="addnewemail", value="save email"></input><button class="removeemailfield">remove</button></form><br>');         });           $('.removeemailfield').click(function() {             $(emailcount).remove();          });     });

here jade file: (it works correctly, maybe visual purposes)

extends layout block content        div.centercontent         div             form.validateform(method="post", action="/edituserprofile")                     legend edit profile                     input(type="text", name="firstname", maxlength="20", placeholder=ufirstname, value=ufirstname)                     br                     input(type="text", name="lastname", maxlength="20", placeholder=ulastname, value=ulastname)                     br                     input(type="email", name="email", maxlength="20", placeholder=uemail, value=uemail)                     br                     - if(uemaillist.length > 0)                         userc in uemaillistcount                             usere in uemaillist                                 input(type="email", name=userc, maxlength="20", placeholder=usere, value=usere)                                 br                     input(type="number", name="phone", maxlength="20", placeholder=uphone, value=uphone)                     br                     input(type="date", name="birthday", value=ubirthday)                     br                     input.btn.btn-primary(type="submit", name="update", value="save")                     a(href="/userprofile")                         button.btn(type="button") cancel                     hr         div#addinfo             label add email address:                   button.addemail add email             br             label add phone number:                   button.addphone add phone number

you can try this:

$("."+emailcount).remove(); i--;

if want add or remove several times make sure emailcount set right value, when adding you're not setting again , when removing you're not changing well.
