$("#cform")[0].reset();

或穿便衣:

document.getElementById("cform").reset();

你可以在你的费用范围内这样做。

$.post( mail.php ,{name:$( #name ).val(),
                              email:$( #e-mail ).val(),
                              phone:$( #phone ).val(),
                              message:$( #message ).val()},

            //return the data
            function(data){

              //hide the graphic
              $( .bar ).css({display: none });
              $( .loader ).append(data);

              //clear fields
              $( input[type="text"],textarea ).val(  );

            });

使用:

$( form.contactForm input[type="text"],texatrea, select ).val(  );

或如果你提到<代码>的表格 * E/CN.6/2009/1。

$( input[type="text"],texatrea, select , this).val(  );

:input === <input> + <select>s + <textarea>s

$( .contactForm ).submit(function(){
    var that = this;

    //...more form stuff...

    $.post( mail.php ,{...params...},function(data){

        //...more success stuff...

        that.reset();
    });
});

简单

$( #cform )[0].reset();

它的工作是:在麻省成功之后,把这一职能称为“你”并寄出其表象。 例如:

This function clear all input fields value including button, submit, reset, hidden fields

function resetForm(formid) {
 $( #  + formid +   :input ).each(function(){  
  $(this).val(  ).attr( checked ,false).attr( selected ,false);
 });
}

* This function clears all input fields value except button, submit, reset, hidden fields * */

 function resetForm(formid) {
   $( :input , # +formid) .not( :button, :submit, :reset, :hidden ) .val(  )
  .removeAttr( checked ) .removeAttr( selected );
  }

例如:

<script>
   (function($){
       function processForm( e ){
           $.ajax({
               url:  insert.php ,
               dataType:  text ,
               type:  post ,
               contentType:  application/x-www-form-urlencoded ,
               data: $(this).serialize(),
               success: function( data, textStatus, jQxhr ){
                $( #alertt ).fadeIn(2000);
                $( #alertt ).html( data );
                $( #alertt ).fadeOut(3000);
               resetForm( userInf );
            },
            error: function( jqXhr, textStatus, errorThrown ){
                console.log( errorThrown );
            }
        });

        e.preventDefault();
    }

    $( #userInf ).submit( processForm );
})(jQuery);

 function resetForm(formid) {
$( :input , # +formid) .not( :button, :submit, :reset, :hidden ) .val(  )
  .removeAttr( checked ) .removeAttr( selected );
 }
  </script>

$.post( mail.php ,{name:$( #name ).val(),
                          email:$( #e-mail ).val(),
                          phone:$( #phone ).val(),
                          message:$( #message ).val()},

        //return the data
        function(data){
           if(data==<when do you want to clear the form>){

           $( #<form Id> ).find( :input ).each(function() {
                 switch(this.type) {
                      case  password :
                      case  select-multiple :
                      case  select-one :
                      case  text :
                      case  textarea :
                          $(this).val(  );
                          break;
                      case  checkbox :
                      case  radio :
                          this.checked = false;
                  }
              });
           }      
   });

Set id in form when you submitting form

     <form action="" id="cform">

       <input type="submit" name="">

    </form>

   set in jquery 

   document.getElementById("cform").reset(); 

$( #f或mid).reset();

或

document.getElementById( f或mid ).reset();

Vanilla!

I know this post is quite old.
Since OP is using jquery ajax this code will be needed.
But for the ones looking for vanilla.

    ...
    // Send the value
    xhttp.send(params);
    // Clear the input after submission
    document.getElementById( cform ).reset();
}

仅使用就构成标签,如:

  $.ajax({
    type: "POST",
    url: "/demo",
    data: dataString,
    success: function () {
      $("form")[0].reset();
      $("#test").html("<div id= message ></div>");
      $("#message")
        .html("<h2>Contact Form Submitted!</h2>")
        .append("<p>We will be in touch soon.</p>")
        .hide()
        .fadeIn(1500, function () {
          $("#message").append(
            "<img id= checkmark  src= images/check.png  />"
          );
        });
    }
  });
  e.preventDefault();
});

采用“jax reset(a)”方法,在提交后,你可以确定形式。

例如,见以上文:

const form = 文件.getElementById(cform).reset();

If you are using a form tag in your form. Then

$("#cform")[0].reset();

该守则将完美地运作,但如果你不使用任何形式标签,那么你就能够尝试为每个投入领域设定一个空洞的价值。

$( input[type="text"],textarea ).val(  );
