Rails 4 中的 Javascript 多步骤表单 - 无法提交表单

Question

在我对此处找到的多步骤表单实现 javascript 解决方案之前，我的 Rails 表单运行良好。 http://www.jqueryscript.net/form/Creating-A-Modern-Multi-Step-Form-with-jQuery-CSS3.html

它工作正常，但它最终不会提交/存储数据。有什么建议么？这是 .form.html.erb 文件。

$(function() {

//jQuery time
var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches

$(".next").click(function(){
if(animating) return false;
animating = true;

current_fs = $(this).parent();
next_fs = $(this).parent().next();

//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

//show the next fieldset
next_fs.show(); 
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale current_fs down to 80%
scale = 1 - (1 - now) * 0.2;
//2. bring next_fs from the right(50%)
left = (now * 50)+"%";
//3. increase opacity of next_fs to 1 as it moves in
opacity = 1 - now;
current_fs.css({'transform': 'scale('+scale+')'});
next_fs.css({'left': left, 'opacity': opacity});
}, 
duration: 800, 
complete: function(){
current_fs.hide();
animating = false;
}, 
//this comes from the custom easing plugin
easing: 'easeInOutBack'
});
});

$(".previous").click(function(){
if(animating) return false;
animating = true;

current_fs = $(this).parent();
previous_fs = $(this).parent().prev();

//de-activate current step on progressbar
$("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

//show the previous fieldset
previous_fs.show(); 
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale previous_fs from 80% to 100%
scale = 0.8 + (1 - now) * 0.2;
//2. take current_fs to the right(50%) - from 0%
left = ((1-now) * 50)+"%";
//3. increase opacity of previous_fs to 1 as it moves in
opacity = 1 - now;
current_fs.css({'left': left});
previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
}, 
duration: 800, 
complete: function(){
current_fs.hide();
animating = false;
}, 
//this comes from the custom easing plugin
easing: 'easeInOutBack'
});
});

$(".submit").click(function(){
return false;
})

});

Answer 1

此时js代码中:

$(".submit").click(function(){
  return false;
})

您需要实现提交功能。类似于(使用 coffeescript):

jqxhr = $.post(
  url
  (data, textStatus, jqXHR) -> 
    console.log 'i guess it worked'
)
jqxhr.fail ->
  console.log jqxhr.responseText 

当然，这假设您已经设置了 url 值。

所以，你的代码最终会看起来像这样(同样，在 coffeescript 中......你必须转换回常规 js):

$(".submit").click ->
  jqxhr = $.post(
    url
    (data, textStatus, jqXHR) -> 
      console.log 'i guess it worked'
  )
  jqxhr.fail ->
    console.log jqxhr.responseText 

关于URL是怎么设置的，在你的非js版本中，你在提交按钮上设置了什么URL？
