Question

I'm new to Modals, I have a Form and when the user clicks submit, It will show a Modal confirming if the user wants to submit, the modal also contains the user input from the form fields. I searched all over the internet but can't find the right one on my needs. And all I see is that they tag the click event to open modal on aa link. i have a input type submit. Can you give examples or ideas? Thanks! Here's my sample form.

<form role="form" id="formfield" action="inc/Controller/OperatorController.php" method="post"  enctype="multipart/form-data" onsubmit="return validateForm();">
<input type="hidden" name="action" value="add_form" /> 

       <div class="form-group">
         <label>Last Name</label><span class="label label-danger">*required</span>
         <input class="form-control" placeholder="Enter Last Name" name="lastname" id="lastname">
       </div>

        <div class="form-group">
          <label>First Name</label><span class="label label-danger">*required</span>
          <input class="form-control" placeholder="Enter First Name" name="firstname" id="firstname">
       </div>

  <input type="submit" name="btn" value="Submit" id="submitBtn" class="btn btn-default" data-confirm="Are you sure you want to delete?"/>
  <input type="button" name="btn" value="Reset" onclick="window.location='fillup.php'" class="btn btn-default" data-modal-type="confirm"/>
</form>

Answer 1

So if I get it right, on click of a button, you want to open up a modal that lists the values entered by the users followed by submitting it.

For this, you first change your input type="submit" to input type="button" and add data-toggle="modal" data-target="#confirm-submit" so that the modal gets triggered when you click on it:

<input type="button" name="btn" value="Submit" id="submitBtn" data-toggle="modal" data-target="#confirm-submit" class="btn btn-default" />

Next, the modal dialog:

<div class="modal fade" id="confirm-submit" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                Confirm Submit
            </div>
            <div class="modal-body">
                Are you sure you want to submit the following details?

                <!-- We display the details entered by the user here -->
                <table class="table">
                    <tr>
                        <th>Last Name</th>
                        <td id="lname"></td>
                    </tr>
                    <tr>
                        <th>First Name</th>
                        <td id="fname"></td>
                    </tr>
                </table>

            </div>

            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a href="#" id="submit" class="btn btn-success success">Submit</a>
            </div>
        </div>
    </div>
</div>

Lastly, a little bit of jQuery:

$('#submitBtn').click(function() {
     /* when the button in the form, display the entered values in the modal */
     $('#lname').text($('#lastname').val());
     $('#fname').text($('#firstname').val());
});

$('#submit').click(function(){
     /* when the submit button in the modal is clicked, submit the form */
    alert('submitting');
    $('#formfield').submit();
});

You haven't specified what the function validateForm() does, but based on this you should restrict your form from being submitted. Or you can run that function on the form's button #submitBtn click and then load the modal after the validations have been checked.

$('form button[type="submit"]').on('click', function () {
   $(this).parents('form').submit();
});

I noticed some of the answers were not triggering the HTML5 required attribute (as stuff was being executed on the action of clicking rather than the action of form send , causing to bypass it when the inputs were empty):

1. Have a <form id='xform'></form> with some inputs with the required attribute and place a <input type='submit'> at the end.
2. A confirmation input where typing "ok" is expected <input type='text' name='xconf' value='' required>
3. Add a modal_1_confirm to your html (to confirm the form of sending).
4. (on modal_1_confirm) add the id modal_1_accept to the accept button.
5. Add a second modal_2_errMsg to your html (to display form validation errors).
6. (on modal_2_errMsg) add the id modal_2_accept to the accept button.
7. (on modal_2_errMsg) add the id m2_Txt to the displayed text holder.

8. The JS to intercept before the form is sent:

    $("#xform").submit(function(e){ var msg, conf, preventSend; if($("#xform").attr("data-send")!=="ready"){ msg="Error."; //default error msg preventSend=false; conf=$("[name='xconf']").val().toLowerCase().replace(/^"|"$/g, ""); if(conf===""){ msg="The field is empty."; preventSend=true; }else if(conf!=="ok"){ msg="You didn't write \\"ok\\" correctly."; preventSend=true; } if(preventSend){ //validation failed, show the error $("#m2_Txt").html(msg); //displayed text on modal_2_errMsg $("#modal_2_errMsg").modal("show"); }else{ //validation passed, now let's confirm the action $("#modal_1_confirm").modal("show"); } e.preventDefault(); return false; } }); 

`9. Also some stuff when clicking the Buttons from the modals:

$("#modal_1_accept").click(function(){
    $("#modal_1_confirm").modal("hide");
    $("#xform").attr("data-send", "ready").submit();
});

$("#modal_2_accept").click(function(){
    $("#modal_2_errMsg").modal("hide");
});

Important Note: So just be careful if you add an extra way to show the modal, as simply clicking the accept button $("#modal_1_accept") will assume the validation passed and it will add the "ready" attribute:

• The reasoning for this is that $("#modal_1_confirm").modal("show"); is shown only when it passed the validation, so clicking $("#modal_1_accept") should be unreachable without first getting the form validated.

Answer 4

You can use browser default prompt window. Instead of basic <input type="submit" (...) > try:

<button onClick="if(confirm(\'are you sure ?\')){ this.form.submit() }">Save</button>

Answer 5

It is easy to solve, only create an hidden submit:

<button id="submitCadastro" type="button">ENVIAR</button>
<input type="submit" id="submitCadastroHidden" style="display: none;" >

with jQuery you click the submit:

$("#submitCadastro").click(function(){
    if($("#checkDocumentos").prop("checked") == false){
        //alert("Aceite os termos e condições primeiro!.");
        $("#modalERROR").modal("show");
    }else{
        //$("#formCadastro").submit();
        $("#submitCadastroHidden").click();                     
    }
});
