使用jQuery（如果需要CSS3），如何创建一个步骤之间平滑过渡的多步骤表单？

例如，如果我有这样的三步形式，如何平滑步骤之间的过渡？

//shows #form_part{n} and hides the other parts
function shows_form_part(n){

  var i = 1, p = $("#form_part"+(i).toString());
  while (p.length != 0){

      if (i == n){
          p.show();
      }
      else{
          p.hide();        
      }
      i++;
      p = $("#form_part"+(i).toString());
  }

}

//change accordingly, just an example
function submit_form() {
  var sum = Number($("#num1").val()) + 
            Number($("#num2").val()) + 
            Number($("#num3").val());
  alert("The sum result is: " + sum);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body onload="shows_form_part(1)">
<form>
  <div id="form_part1">
    Part 1<br>
    <input type="number" value="1" id="num1"><br>
    <!--form elements 1-->
    <button type="button" onclick="shows_form_part(2)">&raquo;</button>
  </div>
  <div id="form_part2">
    Part 2<br>
    <input type="number" value="2" id="num2"><br>
    <!--form elements 2-->
    <button type="button" onclick="shows_form_part(1)">&laquo;</button>
    <button type="button" onclick="shows_form_part(3)">&raquo;</button>
  </div>
  <div id="form_part3">
    Part 3<br>
    <!--form elements 3-->
    <input type="number" value="3" id="num3"><br>
    <button type="button" onclick="shows_form_part(2)">&laquo;</button>
    <button type="button" onclick="submit_form()">Sum</button>
  </div>
</form>
</body>

实现这一目标的一种方法是在每个表单步骤.show(speed)中使用jQuery方法.hide(speed)和div中的参数。 speed参数可以是"slow"，"fast"或转换的时间（以毫秒为单位）。

然后需要一个显示和隐藏相应表单步骤div的函数。以下函数仅显示#form_part{n}并隐藏其他表单部分。在HTML部分中，只需要使用div按顺序命名每个表单id="form_part{n}"，即form_part1，form_part2等。

//shows #form_part{n} and hides the other parts
function shows_form_part(n){

  var i = 1, p = $("#form_part"+(i).toString());
  while (p.length != 0){

      if (i == n){
          p.show("slow");
      }
      else{
          p.hide("slow");        
      }
      i++;
      p = $("#form_part"+(i).toString());
  }

}

//change accordingly, just an example
function submit_form() {
  var sum = Number($("#num1").val()) + 
            Number($("#num2").val()) + 
            Number($("#num3").val());
  alert("The sum result is: " + sum);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body onload="shows_form_part(1)">
<form>
  <div id="form_part1">
    Part 1<br>
    <input type="number" value="1" id="num1"><br>
    <!--form elements 1-->
    <button type="button" onclick="shows_form_part(2)">&raquo;</button>
  </div>
  <div id="form_part2">
    Part 2<br>
    <input type="number" value="2" id="num2"><br>
    <!--form elements 2-->
    <button type="button" onclick="shows_form_part(1)">&laquo;</button>
    <button type="button" onclick="shows_form_part(3)">&raquo;</button>
  </div>
  <div id="form_part3">
    Part 3<br>
    <!--form elements 3-->
    <input type="number" value="3" id="num3"><br>
    <button type="button" onclick="shows_form_part(2)">&laquo;</button>
    <button type="button" onclick="submit_form()">Sum</button>
  </div>
</form>
</body>

你可以这样做：

＆＃13;
＆＃13; 
$(document).ready(function () {
  var navListItems = $('div.setup-panel div a'),
          allWells = $('.setup-content'),
          allNextBtn = $('.nextBtn');

  allWells.hide();

  navListItems.click(function (e) {
      e.preventDefault();
      var $target = $($(this).attr('href')),
              $item = $(this);

      if (!$item.hasClass('disabled')) {
          navListItems.removeClass('btn-primary').addClass('btn-default');
          $item.addClass('btn-primary');
          allWells.hide();
          $target.show();
          $target.find('input:eq(0)').focus();
      }
  });

  allNextBtn.click(function(){
      var curStep = $(this).closest(".setup-content"),
          curStepBtn = curStep.attr("id"),
          nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next().children("a"),
          curInputs = curStep.find("input[type='text'],input[type='url']"),
          isValid = true;

      $(".form-group").removeClass("has-error");
      for(var i=0; i<curInputs.length; i++){
          if (!curInputs[i].validity.valid){
              isValid = false;
              $(curInputs[i]).closest(".form-group").addClass("has-error");
          }
      }

      if (isValid)
          nextStepWizard.removeAttr('disabled').trigger('click');
  });

  $('div.setup-panel div a.btn-primary').trigger('click');
});
