jQuery Ajax在提交表单上获取当前URL

Question

我使用了https://scotch.io/tutorials/submitting-ajax-forms-with-jquery中的代码来发布这些表单中的数据

 <form id="request" method="post" autocomplete="off" class="form-horizontal row scrollTo" novalidate="novalidate">
    <div class="form-group row">
    <label class="control-label label-font" for="lastname">Lastname</label>
    <input name="lastname" id="lastname" class="form-control required" type="text">
    <label class="control-label label-font" for="firstname">Firstname</label>
    <input name="firstname" id="firstname" class="form-control required" type="text">
    </div>
    <div class="form-group row">
    <label class="control-label label-font" for="mobile">Mobile</label>
    <input name="mobile" id="mobile" class="form-control required number" type="text" minlength="10" maxlength="10">
    <label class="control-label label-font" for="vat">vat</label>
    <input name="vat" id="vat" class="form-control validVAT required" maxlength="9" type="text">
    </div>
    <div class="form-group row">
    <label class="control-label label-font" for="address">Address</label>
    <input name="address" id="address" class="form-control required" type="text">
    <label class="control-label label-font" for="streetno">Streetno</label>
    <input name="streetno" id="streetno" class="form-control required" type="text">
    </div>
    <div class="form-group row">
    <label class="control-label label-font" for="user_postcode">Postcode</label>
    <select name="user_postcode" id="user_postcode" class="form-control select2 required select2-hidden-accessible" tabindex="-1" aria-hidden="true"><option value="">Select</option><optgroup label="country1">
    <option value="3002123">3002123 Las Vegas</option><option value="3002723">3002723 Los Angeles</option></optgroup></select><span class="select2 select2-container select2-container--default" dir="ltr" style="width: 100px;"><span class="selection"><span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-labelledby="select2-user_postcode-container"><span class="select2-selection__rendered" id="select2-user_postcode-container" title="3002123 Las Vegas">3002123 Las Vegas</span><span class="select2-selection__arrow" role="presentation"><b role="presentation"></b></span></span></span><span class="dropdown-wrapper" aria-hidden="true"></span></span> </div>
    </div>
    <label class="control-label label-font" for="user_email">Email</label>
    <input name="user_email" id="user_email" class="form-control required" type="text">
    </div>
    <div class="form-group row">
    <label class="control-label label-font" for="notes">Notes</label>
    <textarea type="text" name="notes" id="notes" class="form-control"></textarea>
    </div>
    <div class="form-group text-center">
    <input type="hidden" name="host"><input type="hidden" name="userID" class="userID" value="ho9fbhp3mhb"><input type="hidden" name="usage" value="auto">
    <button type="submit" class="btn btn-primary btn-sm" data-wizard="letters">Submit</button>
    </div>
    </form>

在.php文件中。

<script type="text/javascript">

            jQuery(document).ready(function() {

                jQuery("#request").submit(function(event) {

                    var formData = {
                        'lastname'         : jQuery('input[name=lastname]').val(),
                        'firstname'        : jQuery('input[name=firstname]').val(),
                        'phone'            : jQuery('input[name=mobile]').val(),
                        'afm'              : jQuery('input[name=vat]').val(),
                        'address'          : jQuery('input[name=address]').val(),
                        'address_no'       : jQuery('input[name=streetno]').val(),
                        'user_postcode'    : jQuery('select[name=user_postcode]').val(),
                        'email'            : jQuery('input[name=user_email]').val(),
                        'notes'            : jQuery('textarea[name=notes]').val()
                    };

                    jQuery.ajax({
                        type        : 'POST', 
                         url         : 'process.php', // the url where we want to POST 
                        data        : formData, 
                        dataType    : 'json', 
                                    encode          : true
                    })
                        .done(function(data) {

                            console.log(data); 

                        });

                    event.preventDefault();
                });

            });

        </script>

这是我编写的代码，但是我想将当前URL保存到.php文件中。 哪个代码可以做到这一点？ 我在哪里以及如何输入代码？ 另外，仅当表单有效时，我才能设置所有这些代码吗？

Answer 1

window.location.href属性返回当前页面的URL。

 console.log(window.location.href); 

另外： https : //www.w3schools.com/js/js_window_location.asp

如果我们遇到问题

var formData = {
  'lastname': jQuery('input[name=lastname]').val(),
  'firstname': jQuery('input[name=firstname]').val(),
  'phone': jQuery('input[name=mobile]').val(),
  'afm': jQuery('input[name=vat]').val(),
  'address': jQuery('input[name=address]').val(),
  'address_no': jQuery('input[name=streetno]').val(),
  'user_postcode': jQuery('select[name=user_postcode]').val(),
  'email': jQuery('input[name=user_email]').val(),
  'notes': jQuery('textarea[name=notes]').val(),
  'url' : window.location.href
};

你可以这样

Answer 2

向formData添加另一个属性：

var formData = {
    'lastname'         : jQuery('input[name=lastname]').val(),
    'firstname'        : jQuery('input[name=firstname]').val(),
    'phone'            : jQuery('input[name=mobile]').val(),
    'afm'              : jQuery('input[name=vat]').val(),
    'address'          : jQuery('input[name=address]').val(),
    'address_no'       : jQuery('input[name=streetno]').val(),
    'user_postcode'    : jQuery('select[name=user_postcode]').val(),
    'email'            : jQuery('input[name=user_email]').val(),
    'notes'            : jQuery('textarea[name=notes]').val(),
    'url'              : location.href
};
