Allow field validation in ajax.

[Eugene TUYIZERE]

Friends,

The ajax codes below successfully save the records in the database without page loading. But what I want is to validate the fields first before saving. The codes do not validate the empty field. How can I include that validation ? please help

<script>

$(".submit_btn").click(function(){

var form=new FormData($("#ReportForm")[0]);

//AJAX CODE

var xhr=new XMLHttpRequest();

xhr.onreadystatechange=function(){

if(xhr.status==200){

console.log(xhr.responseText);

}

}

xhr.open("POST","{% url 'report_create' %}",true);

$("#progressbar").show();

//UPDATING PROGRESS BAR

xhr.upload.addEventListener("progress",function(ev){

if(ev.lengthComputable){

var percentage=(ev.loaded/ev.total*100|0);

$("#progressbar").css({"width":""+percentage+"%"}).text("Uploading .."+percentage+"%");

console.log(percentage);

if(percentage>=100){

location.reload()

}

}

});

xhr.send(form);

})

</script>

Regards,

Eugene

You are not submitting your form which Inturn is not validating. For validations to run you need to submit a form.

Give the submit button attribute type="submit", then add an event listener for form submit in your javascript.

$("#ReportForm").on('submit', function(event) {

       // here event is submit type event object

       event.preventDefault() // this is added to prevent default execution of form submit event which will stop the page reload. 

       // here event.target is your form so you can use that to get data as let data = new FormData(event.target) 

})

If you specifically trying to validate the form on the basis of empty input field, then simply include  required attribute in you input field

 <input type="text" id="username" name="username" required>

and for more validation , you just validate all the thing in HTML only using django template tags... 

here I am including a descent approach ... 

     <form method = "POST" >{% csrf_token %}

            {% load bootstrap_tags %} 

           {{form.non_field_errors}}

           <!-- {{ form|as_bootstrap }}       -->

           <div class = "profile-root-inner"> 

             <ul class="profile-form-field">                        

                   

               <li>

                 <ul>  

                                     

                      {% if form.username.errors %}                            

                      <li>{{form.username.errors}}</li>      

                      {% endif %}

                      <li><label for="{{ form.userame.id_for_label}}">Username</label></li>                  

                       <li>{{form.username}}</li>

                     </ul>  

               </li> 

               <li>

                 <ul>                

                   {% if form.email.errors %}                            

                   <li>{{form.email.errors}}</li>      

                   {% endif %}

                   <li><label for="{{ form.email.id_for_label}}">Email</label></li>                   

                      <li>{{form.email}}</li>

                     </ul>  

               </li> 

                   <li>

                     <ul>   

                           {% if form.password1.errors %}                            

                               <li>{{form.password1.errors}}</li>      

                             {% endif %}

                           <li><label for="{{ form.password1.id_for_label}}">Enter the Password</label></li>                         

                          <li>{{form.password1}}</li>

                     </ul>  

                   </li> 

                   <li>

                     <ul>           

                       {% if form.password2.errors %}     

                         <li>{{form.password2.errors}}</li>

                       {% endif %} 

                         <li><label for="{{form.password2.id_for_label}}">Confirm Password</label></li>

                         <!-- <li><input class= "profile-input-field" placeholder="{{blogger.user_email}}" name = "user_email" type = "email" ></li> -->

                         <li>{{form.password2}}</li>

                     </ul>  

                   </li>

                                 

                   <li>

                     <ul>    

                       {% if form.captcha.errors %}     

                         <li>{{form.captcha.errors}}</li>

                       {% endif %}             

                          <li><label for="{{form.captcha.id_for_label}}">Captcha</label></li>                        

                       <li>{{form.captcha}}</li>

                       </ul>  

                     </li>                    

            </div>

               <button type = "submit" class="btn btn-success">Register</button>

            </form>

if any validation error has caught , then it will shown at {{form.captcha.errors}}
