How to submit a form in Semantic UI?

问题

I know how to validate a form using Semantic UI, and can even read in console the message "Form has no validation errors, submitting." However, where is this submitting to? I want to actually submit the form, but the way Semantic UI is laid out I don't seem to be able to specify where to submit to or anything.

I read this tutorial, but that uses Angular for submission and not just Semantic UI.

Am I missing something really simple here?

回答1:

You can use jQuery's ajax:

   //Get value from an input field
   function getFieldValue(fieldId) { 
      // 'get field' is part of Semantics form behavior API
      return $('.ui.form').form('get field', fieldId).val();
   }

   function submitForm() {
      var formData = {
          field1: getFieldValue('someId')
      };

      $.ajax({ type: 'POST', url: '/api/someRestEndpoint', data: formData, success: onFormSubmitted });
   }

   // Handle post response
   function onFormSubmitted(response) {
        // Do something with response ...
   }

EDIT: also, you can use the onSuccess method of the form to run the submitForm function, ie when you initialize the form:

$('.ui.form').form(validationRules, { onSuccess: submitForm });

onSuccess will only be called when the 'Submit' button is clicked and the form is valid based on the rules you specify.

EDIT: If you want the regular HTML form behavior, you will need to add the semantic css classes to the form tag.

<form class="ui form" method="POST" action="/signup">...</form>

And then you set up the validation rules using jQuery. This will give you the default HTML form behavior, ie when you hit the submit button, it will make a POST request to /signup in the case above. If any of your rules trigger, the submit is prevented until there is no validation errors.

use the original submit button but add semantic button style:

<input type="submit" value="Submit" class="ui button" />
<input type="submit" value="Submit" class="ui teal button big"/>

Semantic UI has it's own API to submit form. for example:

$('.ui.form .submit.button')
.api({
    url: 'server.php',
    method : 'POST',
    serializeForm: true,
    beforeSend: function(settings) {
    },
    onSuccess: function(data) {
    }
});

The easiest way is to retrofit a standard HTML form use the code below.

Start with a basic working standard HTML form with a submit button and this will take your values and post them to your form destination, returning the output below your form submit button.

Its a good time to double check you are successfully linking to jquery, semantic javascript and semantic css at this point.
Add class="ui form" to your form tag .
Add the javascript below.

$(document).ready(function() {

// validation 
 $('.ui.form').form({
    email: {
      identifier : 'email',
      rules: [
        {
          type   : 'email',
          prompt : 'Please enter an email'
        }
      ]
    }
},
{
    inline: true,
    on: 'blur',
    transition: 'fade down', 
    onSuccess: validationpassed
});

// called if correct data added to form 
function validationpassed() {

    // Multiple instances may have been bound to the form, only submit one.
    // This is a workaround and not ideal. 
    // Improvements welcomed. 

    if (window.lock != "locked") { 
        var myform = $('.ui.form');
        $.ajax({
            type: myform.attr('method'),
            url: myform.attr('action'),
            data: myform.serialize(),
            success: function (data) {
                //if successful at posting the form via ajax.
                myformposted(data);
                window.lock = "";
            }
        });
    } 
    window.lock = "locked";
}

// stop the form from submitting normally 
$('.ui.form').submit(function(e){ 
    //e.preventDefault(); usually use this, but below works best here.
    return false;
});




function myformposted(data) { 
    // clear your form and do whatever you want here 
    $('.ui.form').find("input[type=text], textarea").val("");
    //$('.ui.submit.button').after("<div>Message sent. Thank you.</div>");
    $('.ui.submit.button').after(data);
} 

});

Basic form:

    <form action="process.php" method="post" class="ui form">
    <div class="field">
    <label>title</label>
        <input name="email" type="text">
    </div> 
    <input type="submit" class="ui button"/>
    </form>

If you want the error message to show in a box rather than within the form itself include this in your form, and remove the words "inline: true," and Semantic UI does the rest:

<div class="ui info message"></div>

NOTE: Using form tags with Semantic UI isn't strictly necessary as you only really need a div with the classes "ui form", however this retrofit code does require a form tag.

What if you don't wana use ajax?!

Use this one:

$( "#reg_btn" ).click(function(event){
    event.preventDefault();
    $('#register_form').submit();

});

in this case u can use <button> tag... there is no need to use classic tag instead

回答6:

Semantic UI is based on jQuery and CSS so if you want to submit your form data you have some way to do that:

Send your form data with AJAX
Use some jqQuery plugins like this
Trick!

Put a submit button and set its display to none. When a user clicks on the div button throw that event to the submit button, in this way:
```
$("div_button_selector").on("click", function(){
   $("input[type='submit']").trigger('click');
});
```

See post Adding errors to form validation doesn't work? for form and error validation. Since Semantic UI is a client side tool for user interface, this is the php for "self submitting / same code page" contact email. Since the purpose of Semantic UI is not logic processing, what language and or method do you want to use for form submission? JS/jquery client side or serverside php, rails, etc.? Keep in mind Semantic UI is dependent on jquery.

<?php    
if (isset($_POST["email"]))
{
    if ($_POST["email"] != "")
    {
        $from = htmlentities($_POST["email"]); 
        $subject = htmlentities($_POST["subject"]);
        $message = htmlentities($_POST["message"]);
        $message = wordwrap($message, 70);
        mail("valid-server-email-username@valid-server-address", $subject, $message, "From: $from\n");
        $_POST["email"] = "";
        $_POST["subject"] = "";
        $_POST["message"] = "";
        unset($GLOBALS['email']);
        header("location: /");
    }
}

If you have a form like this

<div class="ui form segment">
  <p>Tell Us About Yourself</p>
  <div class="field">
    <label>Name</label>
    <input placeholder="First Name" name="name" type="text">
  </div>
  <div class="field">
    <label>Username</label>
    <input placeholder="Username" name="username" type="text">
  </div>
  <div class="field">
    <label>Password</label>
    <input type="password" name="password">
  </div>
  <div class="ui blue submit button">Submit</div>
</div>

you can use the foolowing script to send the form

$('.ui.blue.submit.button').on('click', function() {
  submitForm();
});

function submitForm() {
  var formData = $('.ui.form.segment input').serializeArray(); //or .serialize();
  $.ajax({
    type: 'POST',
    url: '/handler',
    data: formData
  });
}
