表格序列化与ajax帖子

Question

I was trying to post the form data with onclick event in an ajax function.but the data are not being posted in the next page. I was using the serialize method of from data submission but its not working. Meanwhile when I use jQuery .val function it captures the right data in th right field

Here is my html:

             <form id="customer_from"  class="form-group">
                <div class="row">
                   <div class="col-lg-2">
                      <div id="customer_information" style="background-color:grey;padding:5px;text-align:center;border:1px solid white;cursor: pointer; cursor: hand;height:50px;font-size:15px;" data-registry-id="<?php echo $_POST['order_number']; ?>" data-order-ref="<?php echo $_POST['order_ref'];  ?>" data-registry-type="<?php echo $_POST['registry_type'];  ?>" data-customer-id="<?php echo $data['customer_id'];?>">
                         Customer Information
                      </div>
                      <div id="registry_details" style="background-color:grey;padding:5px;text-align:center;border:1px solid white;cursor: pointer; cursor: hand;height:50px;font-size:15px;" data-registry-id="<?php echo $_POST['order_number']; ?>" data-order-ref="<?php echo $_POST['order_ref'];  ?>" data-registry-type="<?php echo $_POST['registry_type'];  ?>" data-customer-id="<?php echo $data['customer_id'];?>">

                      </div>
                      <div id="send_email" style="background-color:grey;padding:5px;text-align:center;border:1px solid white;cursor: pointer; cursor: hand;height:50px;font-size:15px;"  data-registry-id="<?php echo $_POST['order_number']; ?>" data-order-ref="<?php echo $_POST['order_ref'];  ?>" data-registry-type="<?php echo $_POST['registry_type'];  ?>" data-customer-id="<?php echo $data['customer_id'];?>">

                   <div class="col-lg-10" id="dynamic" >
                      <div class="col-lg-5">

                      <div class="col-lg-5">
                         <label for='customer_address'> Address: <span class='required-field'>*</label>

                         <input name='customer_postal'  type='text' value="<?php echo $data['postal_code'] ?>" class='form-control' required /> </span>
                         <label for='customer_country'> Country: <span class='required-field'>*</label>
                         <select id = "customer_country" name="customer_country" class="form-control" title="Select a Category" required>
                            <?php echo $customer_country; ?>
                         </select>
                         <label class="checkbox-inline"><input type="checkbox" value="yes">Newsletter</label>
                      </div>
                   </div>
                </div>

                <div class="row">
                   <div class="col-sm-10 col-xs-11 col-md-12">
                      <input type="button" class="btn btn-success" id="update-registry" value="Update Registry" style="float:right;">
                      <input type="button" class="btn btn-danger" id="delete-registry" data-registry="<?php echo $_POST['order_ref'];?>" data-type="<?php echo $_POST['registry_type']; ?>" value="Delete" style="float:left;">
                   </div>
                </div>
             </div>
          </form>

and here is the ajax call:

$("#update-registry").on("click",function(){
        $.ajax({
        type: "POST",
        url: "ajax/update_customer.php",
        data:$("from#customer_form").serializeArray(),
        beforeSend: function() {

        },
        success: function(msg) {
            $("#registry").find(".update_registry").html(msg);
        },
        error: function() {
            alert("failure");
        }
    });
})

See the form ID:

<form id="customer_from" 

There is a typo:

 data:$("from#customer_form").serializeArray(),
 //------^^^^----------^^^^should be from
 //------^^^^should be form

change from to form. Even better as IDs are unique so there is no need to prefix the tag name:

 data:$("#customer_from").serializeArray(),
