[英]Rails/Ajax/ jQuery: Pass multiple params from jquery to Rails controller
I need to pass two params (selected option & selected number of persons) from radio buttons through jquery to Rails controller via ajax and would appreciate any help at all on how to do so. 我需要将两个参数(选定的选项和选定的人数)从单选按钮通过jquery通过ajax传递给Rails控制器,并且将非常感谢您提供有关此操作的任何帮助。 Both params are needed to calculate pricing (please see @price code in controller below) and right now I'm only able to pass one param at a time for the calculation.
这两个参数都是计算价格所必需的(请参阅下面的控制器中的@price代码),现在我一次只能传递一个参数进行计算。
My form html code is shown below: 我的表单html代码如下所示:
<%= form_for @cartedactivity, url: carted_activities_path, method: :post, remote: true do |f| %>
1. Choose option
<div class = "options">
<center>
<% @options.each do |option| %>
<div class = "radio" id = "option_radio">
<%= f.radio_button :supplier_activity_option_id, option.id, :onclick => "save_option();" %>
<%= f.label :supplier_activity_option_id, option.option_name, :value => option.id %>
</div>
<% end %>
</center>
</div>
<h5>2. Number of Persons</h5>
<div class = "numbers">
<center>
<h5>
<%@numbers.each do |number| %>
<div class = "radio" id =
"quantity_radio">
<%= f.radio_button :activity_quantity, number, :onclick => "save_quantity();" %>
<%= f.label :activity_quantity, number, :value => number %>
</div>
<% end %>
</h5>
</center>
</div>
<h5>3. Start date
<%= f.date_field :activity_date, min: (Date.today+2.days), max: (Date.today+4.months)%>
</h5>
<hr>
<div id = "check-price-<%=@option%>"></div>
<div class = "booking-btn">
<%= f.submit "Add to Cart", class: "btn btn-book" %>
</div>
<% end %>
</div>
</div>
<br><br>
<script>
function save_option()
{var optionValue = $('input[name = "carted_activity[supplier_activity_option_id]"]:checked').val();
if (optionValue) {
$.ajax({
type: "POST",
url: "/supplier_activities/price_check",
data: { optionValue },
success: function(post){ console.log('success') },
error: function(post){ console.log(this) }
});
}
};
function save_quantity()
{var quantityValue = $('input[name = "carted_activity[activity_quantity]"]:checked').val();
if (quantityValue) {
$.ajax({
type: "POST",
url: "/supplier_activities/price_check",
data: { quantityValue },
success: function(post){ console.log('success') },
error: function(post){ console.log(this) }
});
}
};
The partial html is simply <% @price %> 部分html只是<%@price%>
The controller code is : 控制器代码为:
def price_check
@option = params[:optionValue]
@number = params[:quantityValue]
if !@option.blank? && !@number.blank?
@price = Price.find_by("supplier_activity_option_id = ? AND min_qty_for_price <= ? AND max_qty_for_price >= ?", params[:optionValue], params[:quantityValue], params[:quantityValue]).price_usd
else
@price = 100
end
respond_to do |format|
format.js {render layout: false}
end
end
Found the solution - have passed through the value of both checked radio buttons on each click of any radio button. 找到了解决方案-每次单击任何单选按钮时都要检查两个选中的单选按钮的值。 This means that whenever a radio button is clicked, the values of both checked buttons are passed in at the same time.
这意味着,每当单击单选按钮时,两个选中按钮的值都会同时传递。

if (optionValue) {
$.ajax({
type: "POST",
url: "/supplier_activities/price_check",
data: { optionValue: optionValue, quantityValue: quantityValue },
